NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

'''
Cybersecurity researchers have identified a persistent and ambitious campaign that targets thousands of Docker servers daily with a Bitcoin (BTC) miner.
In a report published on April 3, Aqua Security issued a threat alert over the attack, which has ostensibly “been going on for months, with thousands of attempts taking place nearly on a daily basis.” The researchers warn:
“These are the highest numbers we’ve seen in some time, far exceeding what we have witnessed to date.”
Such scope and ambition indicate that the illicit Bitcoin mining campaign is unlikely to be “an improvised endeavor,” as the actors behind it must be relying on significant resources and infrastructure.

Using its virus analysis tools, Aqua Security has identified the malware as a Golang-based Linux agent, known as Kinsing. The malware propagates by exploiting misconfigurations in Docker API ports. It runs an Ubuntu container, which downloads Kinsing and then attempts to spread the malware to further containers and hosts.
The campaign’s end-goal — achieved by first exploiting the open port and then carrying through with a series of evasion tactics — is to deploy a crypto miner on the compromised host, the researchers say.

Security teams need to up their game, says Aqua
Aqua’s study provides detailed insight into the components of the malware campaign, which stands out as a forceful example of what the firm claims is “the growing threat to cloud native environments.”
Attackers are upping their game to mount ever more sophisticated and ambitious attacks, the researchers note. In response, enterprise security teams need to develop a more robust strategy to mitigate these new risks.
Among their recommendations, Aqua proposes that teams identify all cloud resources and group them in a logical structure, review their authorization and authentication policies, and adjust basic security policies according to a principle of “least privilege.”
Teams should also investigate logs to locate user actions that register as anomalies, as well as implement cloud security tools to strengthen their strategy.
Growing awareness
Last month, Singapore-based unicorn startup Acronis published the results of its latest cybersecurity survey. It revealed that 86% of IT professionals are concerned about cryptojacking — the industry term for the practice of using a computer’s processing power to mine for cryptocurrencies without the owner’s consent or knowledge.

Running a full node. Bitcoin unlimited? XT? Core? Help.

I have a one tb hard drive coming in the mail tomorrow and I plan on using my raspberry pi 3 to run a full node. Now, I'm in favor of a fully dynamic block size. I've done my research, technical and political. How do I express my vote for a bigger block size? Do miners or nodes decide block size? I need to express my vote for a larger, fully dynamic block... and I feel like running a node would do so. Thanks!

An extensive guide to building your financial sovereignty on Ubuntu 18.04

Hello all,
I have written up an extensive guide on building a node box in Ubuntu 18.04. It's aimed at newcomers who wish to use Linux as an operating system or are thinking about making the switch from Windows to Linux.
It covers the basics of installing, configuring, running and maintaining software related to bitcoin. I add my own commentary to elaborate key points.
It is not aimed to be a 'quick and easy' guide. It's more about learning the process and understanding, something I believe is key to financial sovereignty. Everything is configured manually, no scripts, no dockers, no complex terminal commands that you will find difficult to understand.
My intention is to provide you with the basic skills to get you up and running into the world of bitcoin/lightning network using Ubuntu and from there you can explore what else it has to offer. I aim to make other guides in future as well. I'm thinking guides on Blockstream Satellite, maybe HoneyMiner, and making a fully stacked torrent box/media server.
I will say that by no means am I an expert in all things linux/ubuntu. These are just learnings from my own exploration. For feedback, you can hit me up on twitter (@k3tan88) or leave an issue on the GitHub.

How can I create a blockchain from scratch?

Blockchain technology was announced initially as “A Peer-to-Peer Electronic Cash System” by Satoshi Nakamoto in the year 2008. It is a list of transaction records known as blocks and linked together by using cryptography. In other words, blockchain is a distributed ledger and each block consists of cryptographic hash of the previous block, transaction data, and a timestamp.

Eight Steps to Make Blockchain from Scrap

#Step 1
Identify the Right Use-Case
Look for the suitable use-case complementing your business sense and needs. Get your data authenticated and verified by including encryption, and digital signatures. Use, smart asset management to include payment, exchange, escrow, issuance, and retirement payment options.
#Step 2
Identify the Right Consensus Mechanism
Once, you have opted for use-case, you need to choose the right Consensus Mechanism. Over the years, there have been multiple distributed ledger systems you can choose like Byzantine fault tolerant, Proof of stake, Round Robin, Federated consensus, and Derived PBFT.
#Step 3
Choose the Suitable Platform
Fortunately, there are many free of cost and independent blockchain platforms to use such as Chain Core, BigChainDB, Eris:db, Domus Tower Blockchain, Stellar, Symbiont Assembly, Hyperledger Sawtooth Lake, and Quorum.
#Step 4
Designing the Nodes
Blockchain solutions are distinguished into two- Permissioned (Government run land registry) and Permission-less (Where everyone can be a miner such as Bitcoin). The solutions can be private, public, and hybrid. Meanwhile, in this stage decide whether the nodes will access on premise, cloud or both. You also need to opt for base operating systems such as Debian, CentOS, Windows, Ubuntu, and Red Hat.
#Step 5
Create the Blockchain Illustration
Multiple blockchain platforms require vigilant and planned configuration that must include permissions, asset re-issuance, asset issuance, key management, native assets, address formats, and block signatures.
#Step 6
Creating APIs
Some blockchain has inbuilt APIs and some don’t. Your API must generate key pairs, and address, perform audit, authenticate data, smart asset lifecycle management and data storage and retrieval.
#Step 7
Create the Admin and User Interface
Now is the time to choose the right programming languages (JAVA, JavaScript, Ruby, Python, and Solidity), front end, external databases (MongoDB, and MySQL), and severs (mail servers, Web servers, and FTP servers).
#Step 8
Infusing Future Tech
By adding biometrics, bots, artificial intelligence, cloud, data analytics, machine learning and cognitive services you can accentuate your blockchain technology.

A response to the GRS Shill cries

First of all, I think it is right to say that it wouldn’t be fair for the recent reddit to be entirely attributed to the recent 130% rise in GRS price – The price has gone a lot higher when SegWit was activated and a lot higher in the runup to the previous release announcement (22nd September) and was arguably at the ‘floor’ when it was discovered by us.
I’d like to give a little bit of a backstory on the recent discovery of GRS by a small group of people in a hope you realise this isn’t just shilling some shit-coin for a pump and dump. It was never our intention to come across as shilling and certainly not our intention to attract ‘pump and dump’ groups. We merely searched for SegWit-activated coins, and the main one that kept popping up was Groestlcoin, in posts that didn’t even mention Litecoin or Vertcoin. We thought that it was worth investigating further and decided to do some more research, and the more we found we more we realised that this was a genuine diamond amongst the rocks. 254th in market cap, first to activate SegWit, Lightning Network in full development, the list was endless – and seemingly nobody knew about it which was insanity.
In several places we saw that no marketing was done or being actively planned, and it was up to the community to market the coin if they wanted to whilst the 20+ developers keep cracking on to try and be the first to more developments.
We contacted the lead developer, ‘Jackielove4u’ and started a plan to try and market the coin, first by creating a Discord channel for discussions and then by trying to get their great features out to the world and aim for slow-and-steady growth.
In hindsight, a bit more finesse would have been better and the reddit posts got a little out-of-hand, if I didn’t know any better I would have seen GRS as a coin being shilled too on Reddit, and I have accused people of doing the same with Vertcoin in the past. So I thought I’d try to clear up some misconceptions and give one targeted response post to the cries of shilling and try to give the facts to the best of my knowledge, whilst trying to give an unbias opinion as much as I can based on my views and the views of the response that we’ve had.
PROS:
• Segwit Enabled Enabled first)
• Low-Power Mining – This is a selling point but people have said the power consumption is on-par with Vertcoin. I think the mining uses 2 rounds of Groestl algorithm hashing to make it more secure but is still very low on power consumption and hardware wear
• Lightning Network currently in development
• They have had an easy miner solution since 2015 – Although I’d be the first to admit it is a little clunky, but is openly on Git for improvements.
• 3 iOS wallets (Including a shared wallet), 11 android wallets (1x Secure BIP147, 1x Including sending GRS via SMS, 1x ability to use NFC tags as encryption keys), 11 blackberry wallets (Secure), 3 web wallets and 10 desktop wallets with varying features / designs – More to come on the differences soon.
• Over 80 electrum servers
• Working testnet
• Hosts their own block explorer
• Officially maintained by the Bitcoin Debian packaging team
• Ubuntu PPA available
• ASIC resistant, profitable CPU and GPU mining (And has an ARM miner apparently!) We’re just brushing the surface of the great tech that is being developed by the GRS developers.
CONS:
• Elephant in the room – The name. People have called it ugly, most don’t know how to pronounce it (It’s Groosel-coin). The developers are open to a rebrand pending a community vote in 2018.
• I’ve heard a few times ‘that logo looks like a cross between google and wordpress’. Again the logo is open to rebrand/redesign pending a vote (open for suggestions/examples!) but there is some significance in it. The ‘2’ in the logo is for the 2 rounds of Groestl algorithm hashing that is used.
• Obviously little or no marketing up until this point. Marketing is important (if not vital) for the success of a coin so we’re trying to spread some awareness.
• Lots of internet posts saying that it is a scam coin. From what I can see it seems to be because the coin has been ‘pumped-and-dumped’ a few times? By that logic, most coins are scam coins? The block reward dropped 6% a week when it was first launched specifically to prevent pump-and-dumps.
• Rumours of a pre-mine of 0.2% (240,000 coins) when it was first created. I haven’t gotten to the bottom of this to confirm or deny, but if it was true it seems to have been given as rewards for some early marketing (where those odd naked women pictures come from) and some early bounty rewards to get the ball rolling. No pre-mine is ideal but its personally something I can look over now if it IS true.
• Over 70% of the mined coins are owned by the top 100 addresses. Again, this is clearly an issue that many other coins also are facing (albeit some to a lesser extent). I can only guess that the more time that passes being a lesser-known coin, the greater risk that this becomes as the same miners mine for a longer period of time. Not sure if this matters much but it’s also worth noting that 24% of the mined coins appear to be on Bittrex currently.
TL:DR – Trying not to shill GRS, just trying to get the word out. Criticisms about the coin have been noted by the developers and they are very open to change and improvements suggested if they are the popular vote. I recommend that you research more into the coin, coin the discord on https://discord.gg/8VURndr and make a decision based on your own research whether you'd see something in, and like to support the coin.
Apologies for such a long post..

DAG Technology Analysis and Measurement

The report produced by the fire block chain coins Institute, author: Yuan Yuming, Hu Zhiwei, PDF version please read the original text download
Summary
The Fire Coin Blockchain Application Research Institute conducts research on distributed ledger technology based on directed acyclic graph (DAG) data structure from a technical perspective, and through the specific technical test of typical representative project IOTA, the main research results are obtained:
Report body
1 Introduction
Blockchain is a distributed ledger technology, and distributed ledger technology is not limited to the "blockchain" technology. In the wave of digital economic development, more distributed ledger technology is being explored and applied in order to improve the original technology and meet more practical business application scenarios. Directed Acylic Graph (hereinafter referred to as "DAG") is one of the representatives.
What is DAG technology and the design behind it? What is the actual application effect?We attempted to obtain analytical conclusions through deep analysis of DAG technology and actual test runs of representative project IOTA.
It should also be noted that the results of the indicator data obtained from the test are not and should not be considered as proof or confirmation of the final effect of the IOTA platform or project. Hereby declare.
2. Main conclusions
After research and test analysis, we have the following main conclusions and technical recommendations:
3.DAG Introduction
3.1. Introduction to DAG Principle
DAG (Directed Acyclic Graph) is a data structure that represents a directed graph, and in this graph, it cannot return to this point (no loop) from any vertex, as shown in the figure. Shown as follows:
📷
After the DAG technology-based distributed ledger (hereinafter referred to as DAG) technology has been proposed in recent years, many people think that it is hopeful to replace the blockchain technology in the narrow sense. Because the goal of DAG at design time is to preserve the advantages of the blockchain and to improve the shortcomings of the blockchain.
Different from the traditional linear blockchain structure, the transaction record of the distributed ledger platform represented by IOTA forms a relational structure with a directed acyclic graph, as shown in the following figure.
📷
3.2. DAG characteristics
Due to the different data structure from the previous blockchain, the DAG-based distributed ledger technology has the characteristics of high scalability, high concurrency and is suitable for IoT scenarios.
3.2.1. High scalability, high concurrency
The data synchronization mechanism of traditional linear blockchains (such as Ethereum) is synchronous, which may cause network congestion. The DAG network adopts an asynchronous communication mechanism, allowing concurrent writing. Multiple nodes can simultaneously trade at different tempos without having a clear sequence. Therefore, the data of the network may be inconsistent at the same time, but it will eventually be synchronized.

3.2.2. Applicable to IoT scenarios

In the traditional blockchain network, there are many transactions in each block. The miners are packaged and sent uniformly, involving multiple users. In the DAG network, there is no concept of “block”, the smallest unit of the network. It is a "transaction", each new transaction needs to verify the first two transactions, so the DAG network does not need miners to pass the trust, transfer does not require a fee, which makes DAG technology suitable for small payments.
4. Analysis of technical ideas
Trilemma, or "trilemma", means that in a particular situation, only two of the three advantageous options can be selected or one of the three adverse choices must be chosen. This type of selection dilemma has related cases in various fields such as religion, law, philosophy, economics, and business management.Blockchain is no exception. The impossible triangle in the blockchain is: Scalability, Decentralization, and Security can only choose two of them.
If you analyze DAG technology according to this idea, according to the previous introduction, then DAG has undoubtedly occupied the two aspects of decentralization and scalability. The decentralization and scalability of the DAG can be considered as two-sided, because of the asynchronous accounting features brought about by the DAG data structure, while achieving the high degree of decentralization of the participating network nodes and the scalability of the transaction.
5. There is a problem
Since the characteristics of the data structure bring decentralization and scalability at the same time, it is speculated that the security is a hidden danger according to the theory of impossible triangles. But because DAG is a relatively innovative and special structure, can it be more perfect to achieve security? This is not the case from the actual results.
5.1. Double flower problem
The characteristics of DAG asynchronous communication make it possible for a double-flower attack. For example, an attacker adds two conflicting transactions (double spending) at two different locations on the network, and the transactions are continuously forward-checked in the network until they appear on the verification path of the same transaction, and the network discovers the conflict. At this time, the common ancestor nodes that the two transactions are gathered together can determine which transaction is a double-flower attack.
If the trading path is too short, there will be a problem like "Blowball": when most transactions are "lazy" in extreme cases, only the early trading, the trading network will form a minority. Early transactions are the core central topology. This is not a good thing for DAGs that rely on ever-increasing transactions to increase network reliability.
Therefore, at present, for the double flower problem, it is necessary to comprehensively consider the actual situation for design. Different DAG networks have their own solutions.
5.2. Shadow chain problem
Due to the potential problem of double flowers, when an attacker can build a sufficient number of transactions, it is possible to fork a fraudulent branch (shadow chain) from the real network data, which contains a double flower transaction, and then this The branch is merged into the DAG network, and in this case it is possible for this branch to replace the original transaction data.
6. Introduction to the current improvement plan
At present, the project mainly guarantees safety by sacrificing the native characteristics of some DAGs.
The IOTA project uses the Markov chain Monte Carlo (MCMC) approach to solve this problem. The IOTA introduces the concept of Cumulative Weight for transactions to record the number of times the transaction has been cited in order to indicate the importance of its transaction. The MCMC algorithm selects the existing transactions in the current network as a reference for the newly added transactions by weighting the random weights of the accumulated weights. That is, the more referenced the transaction path, the easier it is to be selected by the algorithm. The walk strategy has also been optimized in version 1.5.0 to control the "width" of the transaction topology to a reasonable range, making the network more secure.
However, at the beginning of the platform startup, due to the limited number of participating nodes and transactions, it is difficult to prevent a malicious organization from sending a large number of malicious transactions through a large number of nodes to cause the entire network to be attacked by the shadow chain. Therefore, an authoritative arbitration institution is needed to determine the validity of the transaction. In IOTA, this node is a Coordinator, which periodically snapshots the current transaction data network (Tangle); the transactions contained in the snapshot are confirmed as valid transactions. But Coordinator doesn't always exist. As the entire network runs and grows, IOTA will cancel the Coordinator at some point in the future.
The Byteball improvement program features its design for the witness and the main chain. Because the structure of DAG brings a lot of transactions with partial order, and to avoid double flowers, it is necessary to establish a full order relationship for these transactions to form a transaction backbone. An earlier transaction on the main chain is considered a valid transaction.Witnesses, who are held by well-known users or institutions, form a main chain by constantly sending transactions to confirm other user transactions.
The above scheme may also bring different changes to the platform based on the DAG structure. Taking IOTA as an example, because of the introduction of Coordinator, the decentralization characteristics are reduced to some extent.
7. Actual operation
7.1. Positive effects
In addition to solving security problems, the above solutions can also solve the smart contract problem to some extent.
Due to the two potential problems caused by the native features of DAG: (1) The transaction duration is uncontrollable. The current mechanism for requesting retransmission requires some complicated timeout mechanism design on the client side, hoping for a simple one-time confirmation mechanism. (2) There is no global sorting mechanism, which results in limited types of operations supported by the system. Therefore, on the distributed ledger platform based on DAG technology, it is difficult to implement Turing's complete intelligent contract system.
In order to ensure that the smart contract can run, an organization is needed to do the above work. The current Coordinator or main chain can achieve similar results.
7.2. Negative effects
As one of the most intuitive indicators, DAG's TPS should theoretically be unlimited. If the maximum TPS of the IOTA platform is compared to the capacity of a factory, then the daily operation of TPS is the daily production of the plant.
For the largest TPS, the April 2017 IOTA stress test showed that the network had transaction processing capabilities of 112 CTPS and 895 TPS. This is the result of a small test network consisting of 250 nodes.
For the daily operation of TPS, from the data that is currently publicly available, the average TPS of the main network in the near future is about 8.2, and the CTPS (the number of confirmed transactions per second) is about 2.7.
📷
The average average TPS of the test network is about 4, and the CTPS is about 3.
📷
Data source discord bot: generic-iota-bot#5760
Is this related to the existence of Coordinator? Actual testing is needed to further demonstrate.
8. Measured analysis
The operational statistics of the open test network are related to many factors.For further analysis, we continue to use the IOTA platform as an example to build a private test environment for technical measurement analysis.
8.1. Test Architecture
The relationship between the components we built this test is shown below.
📷
among them:
8.2. Testing the hardware environment
The server uses Amazon AWS EC2 C5.4xlarge: 16 core 3GHz, Intel Xeon Platinum 8124M CPU, 32GB memory, 10Gbps LAN network between servers, communication delay (ping) is less than 1ms, operating system is Ubuntu 16.04.
8.3. Test scenarios and results analysis

8.3.1. Default PoW Difficulty Value

Although there is no concept such as “miners”, the IOTA node still needs to prove the workload before sending the transaction to avoid sending a large number of transactions to flood the network. The Minimum Weight Magnitude is similar to Bitcoin. The result of PoW should be the number of digits of "9", 9 of which is "000" in the ternary used by IOTA. The IOTA difficulty value can be set before the node is started.
Currently for the production network, the difficulty value of the IOTA is set to 14; the test network is set to 9. Therefore, we first use the test network's default difficulty value of 9 to test, get the following test results.
📷
Since each IOTA's bundle contains multiple transfers, the actual processed TPS will be higher than the send rate. But by executing the script that parses zmq, it can be observed that the current TPS is very low. Another phenomenon is that the number of requests that can be sent successfully per second is also low.
After analysis, the reason is that the test uses VPS, so in PoW, the CPU is mainly used for calculation, so the transaction speed is mainly affected by the transmission speed.

8.3.2. Decrease the PoW difficulty value

Re-test the difficulty value to 1 and get the following results.
📷
As can be seen from the results, TPS will increase after the difficulty is reduced. Therefore, the current TPS of the IOTA project does not reach the bottleneck where the Coordinator is located, but mainly because of the hardware and network of the client itself that sends the transaction. The IOTA community is currently working on the implementation of FPGA-based Curl algorithm and CPU instruction set optimization. Our test results also confirm that we can continue to explore the performance potential of the DAG platform in this way.

8.3.3. Reduce the number of test network nodes

Due to the characteristics of DAG, the actual TPS of the platform and the number of network nodes may also be related. Therefore, when the difficulty value is kept at 1, the number of network nodes is reduced to 10 and the test is repeated to obtain the following results.
📷
As can be seen from the results, as the number of nodes decreases, the actual processing of TPS also decreases, and is lower than the transmission rate. This shows that in a DAG environment, maintaining a sufficient size node will facilitate the processing of the transaction.

Mega FAQ (Or: Please come here for your questions first)

Qbundle Guide (Step by step setup & Bootstrap) https://burstwiki.org/wiki/QBundle
1( I want to mine or activate My account. Where do find the multiple coins?
You only need 1, an outgoing transaction or reward reassignment will set the public key. Get them from:
https://www.reddit.com/burstcoinmining/comments/7q8zve/initial_burstcoin_requests/
Or (Faucet list)
https://faucet.burstpay.net/ (if this is empty, come back later)

Or
https://forums.getburst.net/c/new-members-introductions/getting-started-initial-burstcoin-requests
2( I bought coins on Bittrex and want to move to my new wallet, but can't. Why?
Bittrex will only send to accounts with a public key (not a Burst requirement) so see number 1 and either set the name on the account (IF you will not mine) or set the reward recipient to the pool. Either action will enable the account and allow for transfers from Bittrex.
3( I sent coins from Poloniex/anywhere to Bittrex and they don’t show up after a considerable time. Why?
You need to set an unencrypted message on the transaction, informing Bittrex which account to send the funds to (this is in the directions on Bittrex). Did you do this? Contact Bittrex support with all the details and eventually you will get your funds.
4( How much can I make on Burst?
https://explore.burst.cryptoguru.org/tool/calculate
Gives you an average over time assuming a few things like: Average luck/100% uptime/no overlapping/fees on pool/good plot scan time (<20 seconds) if you do not have all of these, you may not see that number.
5( If I use SSD’s would I make more money?
No, it’s 95% capacity and 5% scan time that determine success. More plot area = better deadlines = better chance of forging a block, or better rates from a pool.
6( What is ‘solo’ and ‘pool’ (wasn’t his name Chewbacca?)
Solo is where you attempt to ‘forge’ (mine) a block by yourself; you get 100% of the block reward and fees. But you only receive funds if you forge, no burst for coming in second place.
Pools allow a group of miners to ‘pool’ together their resources and when a miner wins, they give the pool the winnings (this is done by the reward assignment you completed earlier), it is then divided according to different percentages and methods and burst is sent out according to pool rules (minimum pay-out, time, etc.)
7( I have been mining for 2 days and my wallet doesn’t show any Burst WHY?
Mining solo: it is win-or-lose, nothing in between, and wining is luck and plot size. Pool mining: because it costs 1 burst to send burst, the pools have either a time requirement (every X days) or a minimum amount (100 burst +) so you need to research your pool. Some pools allow for you to set the limit (cryptoGuru and similar) to be met before sending
8( How do I see what I have pending?
On CryptoGuru, based pools, it’s the ‘Pending (burst)’ column, other pools, look for the numbers next to your burst ID. One is Paid and the other pending.
9( I’m part of a pool and I forged a block, but I didn’t recieve the total value of the block, why?
A pool has 2 basic numbers that denote the pay-out method, in the format ‘XX-XX’ (i.e. 50-50) The first number is the % paid to the block forger (miner) and the second is the retained value, which is paid to historic ‘shares’ (or, past blocks that the pool didn’t win, but had a miner that was ‘close’ to winning with a good submitted deadline)
Examples of pools:
0-100 (good for <40TB)
20-80 (30-80TB)
50-50 (60-200TB)
80-20 (150-250)
100-0 (solo mine, 150+ TB)
Please note that there is an overlap as this is personal preference and just guidance; a higher historical share value means a smoother pay-out regime, which some people prefer. If fees are not factored in, or are the same on different pools, the pay-out value will be the same over a long enough period.
10( Is XXX model of hard drive good? Which one do you recommend?
CHEAP is best. If you have 2 new hard drives, both covered by warranty, get the one with the lowest cost per TB (expressed as $/TB , calculated by dividing the cost by the number of terabytes) because plot size is KING,
11( How many drives can I have on my machine?
For best performance, you can have up to 2 drives per thread (3 on a new fast AVX2 CPU). So that quad-core core-2-quad can have up to 8 drives, but a more modern i7 with 4 cores + hyper threading can squeeze 8 * 3 or 24 drives. (Performance while scanning will suffer)
12( Can I game while I mine?
Some people have done so, but you cannot have the ‘maximum’ number of drives and play games generally.
13( Can I mine Burst and GPU mine other coins?
Yes, if you CPU Mine Burst.
14( I’m GPU plotting Burst and GPU mining another coin, my plots are being corrupted, why?
My advice is dedicating a GPU to either mining or plotting, don’t try to do both.
15( What is a ‘plot’?
A plot is a file that contains Hashes, these hashes are used to mine burst. A plot is tied to an account, but they can be created (with the same account ID) on other machines and connected back to your miner(s).
16( Where can I trade/buy/sell Burst?
A list of exchanges is maintained on https://www.reddit.com/burstcoin/ (on the right, ‘Exchanges’ tab) the biggest at the moment are Bittrex and Poloniex, some offer direct Fiat-to-Burst purchase (https://indacoin.com for example)
17( Do I have to store my Burst off the exchange?
No, but it’s safer from hackers who target exchanges, if you cannot guarantee the safety or security of your home computer from Trojans etc, then it might be best to leave on an exchange (but enable 2FA security on your account PLEASE!)
18( What security measures can I take to keep my coin safe?
When you create an account, sign out and back in to your wallet (to make sure you have copied the pass phrase correctly) and keep multiple copies of the key (at least one physically printed or written down and in a safe place, better in 2 places) do not disclose the passphrase to anyone. Finally use either a local wallet or a trusted web wallet (please research before using any web wallet)
19( How can I help Burst?
Run a wallet, which will act as a node (or if you’re a programmer, contact the Dev team Bring attention to burst (without ‘shilling’ or trying to get people to buy) And help translate into your local language
Be a productive member of the community and contribute experience and knowledge if you can, or help others get into Burst.
20( Will I get coins on the fork(s) and where will they be?
There will be no new coin, and no new coins to be given/air dropped etc, the forks are upgrades to burst and there will not be a ‘classic’ or ‘new’ burst.
21( Will I need to move my Burst off of the exchange for the fork?
No, your transactions are on the block chain, which will be used on the fork, they will be visible after the move; nothing will need to be done on your side.
22( Where can I read about the progress of Burst and news in general on the community?
There is no finer place than https://www.burstcoin.ist/
23( What are the communities for Burst and the central website?
Main website: https://www.burst-coin.org/
Reddit: https://www.reddit.com/burstcoin and https://www.reddit.com/burstcoinmining/
Burstforum.net: https://www.burstforum.net/
Getburst forum: https://forums.getburst.net/
Official Facebook channel: https://m.facebook.com/groups/398967360565392
(these are the forums that are known to be supporting the current Dev Team)
Other ways to talk to the community:
Discord: https://discordapp.com/invite/RPhpjVv
Telegram (General): https://t.me/burstcoin
Telegram (Mining): https://t.me/BurstCoinMining
24( When will Burst partner up with a company?
Burst is a currency, the USD does not ‘partner up’ with a company, the DEV team will not partner up and give over to special interests.
25( Why is the DEV team anonymous?
They prefer anonymity, as it allows them to work without constant scrutiny and questions unless they wish to engage, plus the aim is for Burst to become a major contender, and this brings issues with security. They will work and produce results, they owe you nothing and if you cannot see the vision they provide then please do not ‘invest’ for short term gain.
26( When moon/Lambo/$100/make me rich?
My crystal ball is still broken, come back to the FAQ later for answer (seriously, this is a coin to hold, if you want to day-trade, good luck to you)
27( How can I better educate myself and learn about Dymaxion?
Read about the Dymaxion here: https://www.reddit.com/burstcoin/wiki/dymaxion
28( My reads are slow, why?
There are many reasons for this, if your computer has a decent spec it’s likely due to USB3 hub issues, or plugging into a USB2 hub, but other reasons can be multiple plots in the same folder, but it’s best to visit the mining subreddit. They can help more than an simple FAQ https://www.reddit.com/burstcoinmining/
29( I have a great idea for Burst (not proof of stake related)?
Awesome! Please discuss with the DEV team on discord https://discordapp.com/invite/RPhpjVv
(Please be aware that this is a public forum, you need to find who to ask/tell)
30( I have a great idea for Burst (Proof of stake related)?
No. if you want a POS, find a POS coin. On the tangle which is being implemented a POS/POW/POC coin can be created, but BURST will always be POC mined. You are welcome to implement a proof of stake coin on this!
31( Will the Dev team burn any coins?
Burst is not an ICO, so any coins will need to be bought to be burnt. You are welcome to donate, but the DEV team have no intention of burning any coins, or increasing the coin cap.
32( When will there be an IOS wallet?
IOS wallet is completed; we are waiting for it to go on the app store. Apple is the delaying factor.
33( Why do overlapping plots matter?
Plots are like collections of lottery tickets (and if only one ticket could win). Having 2 copies is not useful, and it means that you have less coverage of ‘all’ the possible numbers. It’s not good, avoid.
34( My local wallet used to run, I synchronised it before and now it says ‘stopped’. when I start it, it stops after a few seconds, what should I do?
I suggest that you change the database type to portable MariaDB (on Qbundle, at the top, ‘Database’ select, ‘change database’) and then re-import the database from scratch (see 35)
35( Synchronising the block chain is slow and I have the patience of a goldfish. What can I do?
On Qbundle , ‘Database’ select ‘Bootstrap chain’ and make sure the CryptoGuru repository is selected, then ‘start Import’ this will download and quickly stuff the local database (I suggest Portable MariaDB, see 34) (lol, loop)
36( What will the block reward be next month/will the block rewards run out in 6 months?
https://www.ecomine.earth/burstblockreward/ Rewards will carry on into 2026, but transaction fees will be a bigger % by then, and so profitable mining will continue.
37( How can I get started with Burst (wallet/mining/everything) and I need it in a video
https://www.youtube.com/watch?v=LJLhw37Lh_8 Watch and be enlightened.
38( Can I mine on multiple machines with the same account?
Yes, if you want to pool mine this can be done (but be prepared for small issues like reported size being incorrect. Just be sure to keep question 33 in mind.)
39( Why do some of my drives take forever to plot?
Most likely they are SMR drives, it’s best to plot onto another SSD and then move the finished plot/part of a plot across to the SMR drive as this is much quicker. SMR drives are fine on the read, just random writes that are terrible.
So plot an SMR drive quickly, plot to a non SMR or better still SSD drive, in as big a chunk as possible (fewer files better) and move. a version of Xplotter, called Splotter, can do this easily.
https://github.com/NoParamedic/SPlotter
40( I have a great idea; why not get listed on more exchanges!!
Exchanges list coins because of 2 reasons:
  1. Clients email and REQUESTING Burst and provide details like:
    i. https://www.burst-coin.org/information-for-exchanges
  2. The coin pays (often A LOT, seriously we’ve been asked for 50 BTC)
I suggest you speak with your exchange and ask ‘when will they offer Burst?’
41( Do you have a roadmap?
https://www.burst-coin.org/roadmap
42( Why is the price of Burst going up/down/sideways/looping through time?
The price of burst is still quite dependent upon Bitcoin, meaning that if Bitcoin gains, the value of Burst gains, if Bitcoin drops then Burst also drops. If there is news for Burst then we will see something independent of Bitcoin moving. Variations can be because of people buying in bulk or selling in bulk. There are also ‘pump and dump’ schemes that we detest, that can cause spikes in price that have nothing to do with news or Bitcoin, just sad people taking advantage of others.
43( Where is the best place to go with my mining questions?
https://www.reddit.com/burstcoinmining/
or https://t.me/BurstCoinMining
44( What hardware do you advise me to buy, is this computer good?
See question 43 for specific questions on hardware, it depends on so many variables. The ‘best’ in my opinion is a 36 bay Supermicro storage server, usually they have dual 6-core CPU’s and space for 36 drives. No USB cables, plotting and mining monster, anything else, DYOR.
45( Where do you buy your hard drives?
I have bought most from EBay in job lots, and some refurbished drives with short warranties. Everything else I have bought, from Amazon.
46( Can I mine on my Google drive/cloud based storage?
In short: no. If you want to try, and get to maybe 1 TB and then find that your local connection isn’t fast enough, or that shortly after, your account is blocked for various reasons. Please be my guest.
47( Can I mine on my NAS?
Some you can mine with the NAS (if it can run the miner, it can scan locally) but generally they’re not very fast. good for maybe 16 TB? Having a plot on a NAS and mining from another computer depends on the network speed between the NAS and scanning computer. I believe you can scan about 8 TB (maybe a bit more) and keep the scan times to within acceptable, but YMMV.
48( How can I set up a node?
No need to set up a node, just set up a wallet (version 2.0.4) or Qbundle (2.2) and it will do the rest
49( Are the passphrases secured?
I’ll leave the effort to a few people to show how secure a 12-word passphrase is: https://burstforum.net/topic/4766/the-canary-burst-early-warning-system Key point: brute forcing it will be around 13,537,856,339,904,134,474,012,675,034 years.
50( I logged into my account (maybe with a different burst ID) and see no balance!!
I have dealt with this very issue multiple times, and there are only 3 options:
  1. You have typed in the password incorrectly
  2. You have copy-pasted the password incorrectly
  3. You are trying to log into a ‘local wallet’ which the block chain has not finished updating
The last one generally leaves the burst ID the same, but old balances will show. No, this is not a security problem, and yes, windows loves to add spaces after the phrase you enter when copied, and that space is important in getting to your account.
51( Are there channels for my language?
Telegram:
Spanish: https://t.me/burstcoin_es
German: https://t.me/Burstcoinde
Italian: https://t.me/BurstCoinItalia
Forum:
Spanish: https://burst-coin.es/index.php/forum/index
Discord:
Spanish: https://discordapp.com/invite/RaaGna9
Bulgarian: https://discord.gg/r4uzTd
(there are others, please contact me to put up)
52( I am mining in a pool, and it says that my effective capacity is lower than I actually have, why?
  1. If you've not been mining for >48 hours, or just added additional capacity, it will take time.
  2. The value fluctuates (normally, +-5% but can be up to 10% at times)
  3. Read on the ‘Quick info’ tab about adjusting your deadline to compensate for changes i. revisit once a month for best results
  4. If you have overlapping plots it will also be lower so be aware of this (see question 33)
53( What pool should I join?
First of all, read question 9, after you have understood that it depends on the size (and how patient you are) select from the following list: https://www.ecomine.earth/burstpools/
54( What miner to use?
I use Blago’s miner, there are many out there but Blago’s works for me on CPU mining, it can be found in Qbundle.
55( What Wallet to use (I use windows)?
Qbundle: https://github.com/PoC-Consortium/Qbundle/releases/ guide: https://burstwiki.org/wiki/QBundle
56( What Wallet to use (Linux)?
https://package.cryptoguru.org/ for Debian and Ubuntu, for Mac. read:
https://www.ecomine.earth/macoswalletinstallguide/
57( Will i need to 'replot' after POC2 (second fork) happens?
No, there will be a tool which will optimise, but it is not CPU intensive (it basically re-shuffles your plot) and is just IO intensive. You do not need to replot.
TurboPlotter and https://github.com/PoC-Consortium/Utilities/tree/mastepoc1to2.pl are tools that will/can be used to actuate optimization, but PLEASE wait with optimization until after the hard fork.
58( Will the transaction fee always be 1 burst?
No, dynamic fees are coming in the next fork.

Interested in contributing to the BTC network? Here is the steps to get a full node up and running in Linux.

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

DECENT MINING SETUP & RESSOURCES SHORTCUT

To all DECENTants,
I would like to encourage you to become a seeder or witness (actually not miner) on DECENT.

SHORT INTRODUCTION ABOUT ME

As a pioneer with Bitcoin I truly believed in the DCT project and it's proposal. The first day of the ICO release I sent all my BTC balance to the DECENT. Not knowing when and what they will deliver. To participate in this great adventure means a lot to me. Another project from my home country I strongly encourage you to get familiar with is Ethereum. I have been an early CPU miner: before Crypto Currency I used to compute for sience projects grid for Clean Water and Cancer Research. If I hadn't bought Rainforest with the Ripple they distributed to all contributors, I'd be a rich man today. :P

I - SERVER SETUP

A dedicated server with Linux Ubuntu 16.04 LTS is most recommend for 24/7 operation. I suggest you close the root and create a new user with SSH Key, secure the system with a firewall.

1. Create a new user

adduser bob 

2. Elevate him

usermod -aG sudo bob 

3. Generate a new keyset

ssh-keygen 

4- Bind the new keys

ssh-copy-id [email protected]_server_ip 
Copy the keys to your local drive. You'll need them to connect.

5. Change the config file

sudo nano /etc/ssh/sshd_config 
Change Line PasswordAuthentication no

6. Finish with

sudo systemctl reload sshd 

7. Login with your ssh key, user and password

ssh [email protected]_server_ip 

II - PREREQUISITES

1. Grab your tools

sudo apt-get update sudo apt-get install build-essential autotools-dev automake autoconf libtool make cmake checkinstall realpath gcc g++ flex bison doxygen gettext git qt5-default libqt5svg5-dev libreadline-dev libcrypto++-dev libgmp-dev libdb-dev libdb++-dev libssl-dev libncurses5-dev libboost-all-dev libcurl4-openssl-dev python-dev libicu-dev libbz2-dev 

2. Download and build Boost 1.60.0

mkdir -p ~/dev/DECENTfoundation/DECENT-Network-third-party cd ~/dev/DECENTfoundation/DECENT-Network-third-party rm -rf boost_1_60_0* boost-1.60.0* wget https://sourceforge.net/projects/boost/files/boost/1.60.0/boost_1_60_0.tar.gz tar xvf boost_1_60_0.tar.gz mkdir boost-1.60.0_prefix cd boost_1_60_0 export BOOST_ROOT=$(realpath ../boost-1.60.0_prefix) ./bootstrap.sh --prefix=$BOOST_ROOT ./b2 install cd .. rm -rf boost_1_60_0 boost_1_60_0.tar.gz 

III - INSTALLATION

1. Clone the repo

mkdir -p ~/dev/DECENTfoundation cd ~/dev/DECENTfoundation #via ssh $ git clone [email protected]:DECENTfoundation/DECENT-Network.git #via url $ git clone https://github.com/DECENTfoundation/DECENT-Network.git cd DECENT-Network git submodule update --init --recursive 

2. Build and install Decent

mkdir -p ~/dev/DECENTfoundation/DECENT-Network-build cd ~/dev/DECENTfoundation/DECENT-Network-build cmake -G "Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ~/dev/DECENTfoundation/DECENT-Network cmake --build . --target all -- -j -l 3.0 cmake --build . --target install 

IV - USE DECENT

You don't want your server to shut down the process when you lose connection or quit.
I use tmux. Though nohup is sufficient for infrequent access. Use it when you fire up decentd after miner setup.
nohup ./decentd & disown 

1. RUN decentd - On first run decentd will create .decent in the home directory.

~/dev/DECENTfoundation/DECENT-Network-build/artifacts/prefix/bin/decentd 
Always close it via Ctrl+C to save the current state Ctrl+S Freeze Ctrl+Q Resume

2. Get HELP

cd ~/dev/DECENTfoundation/DECENT-Network-build/artifacts/prefix/bin/ ./decentd -h 

3. RUN cli_wallet

~/dev/DECENTfoundation/DECENT-Network-build/artifacts/prefix/bin/cli_wallet 
Close it with Ctrl+D

4. USE cli_wallet

set_password xy unlock xy 

5. IMPORT your account

import_key decentgo_username your_private_key 

6. CREATE 3 sets of keys for your new account

suggest_brain_key 
write them down, don't use the ones below. ;)

1. new owner key

{ "brain_priv_key1": "UNBUSH ROAR CHKALIK STRUE PLATTEN DEMOB COLETIT DECAYER SPERONE SPASMED ANATASE LAGGARD BESPETE AXOID SERAL CHEKI", "wif_priv_key1": "5J4brX9bydADigEtsXZhCZ1YLVXkq8frp4xcKAREQ3Gh3P2DE7e", "pub_key1": "DCT5VNJni7HypYi159qiwazZ1WZUt4p2v7NLQmFCJPDvjBpW2oG8a" } 

2. new active key

{ "brain_priv_key2": "FUSION BLART JAIL FESTAL LAXNESS ROSTEL TITI VANADYL PUG BATATA KAIK ROSETY STUCCO TETE BEMUDDY WUDGE", "wif_priv_key2": "5HvsjRsokHSeeUdRkM88JgLzYJ6vnc2e35CzyZNRnmh1fvm91Jz", "pub_key2": "DCT7G7KeUnMPVKXN2y8M7BnyosLRE3LtSnNp7kbxtYd9xHiBoX6wd" } 

3. new public signing key

{ "brain_priv_key3": "DECESS LABBA PLAN DEHUSK FISTY MOSSER SPURTER SCORIAE INDART UNDYE MASTER STEIGH SAFROLE FLURR THAPSIA JOB", "wif_priv_key3": "5JgMsecySgt2BQsmmEE9QnwAGuudC9fGeZJhreyPatcu2TVY9bs", "pub_key3": "DCT6D7TLeVJmPQWR73XHvEhTVHzTDoG6oTSUyvfGa58nuc5wL96UH" } 

7. CREATE your new account

register_account new_username pub_key1 pub_key2 decentgo_username true 

8. SEND some DCT to your new account

transfer decentgo_username target_username 3.00 DCT "memo" true 

9. IMPORT the new account

import_key new_username wif_priv_key2 

10. Close the Wallet and edit the config.ini inside /root/.decent/data/decentd/

private-key = ["pub_key2","wif_priv_key2"] 

11. Launch again and create your miner

create_miner username "proposal URL" true 

12. Change your signing key to 3rd keypair from suggest_brain_key

update_miner username "proposal URL" public_key3 true 

13. Edit the config.ini again inside /root/.decent/data/decentd/

enable-stale-production = true miner-id = "1.4.X" private-key = ["pub_key3","wif_priv_key3"] 

Your Server is now ready to run a DECENT witness.

Be aware that you should not close your daemon at any time.

V - USEFUL COMMANDS

get_brain_key_info dump_private_keys get_private_key public-key get_account texxi get_miner texxi list_my_accounts list_account_balances texxi set_desired_miner_count username 99

I would highly recommend using Ubuntu Server for this, as long as you know what you are doing without a GUI. Not having a GUI at all means smaller OS size and much less OS tasks. This translates into more power savings. If you are using graphics cards, a non-GUI OS will improve your mining performance. If using an ASIC/etc. you probably will ... WARNING: don't use cpuminer or any miner software on remote hosted machines, it's considered as an abuse of common resources and can be treated as an attack to the hosted system. NOTE: Bitcoin mining is very time consuming and you need a very powerful network of server machines to obtain even a small result (less than a bitcoin in most cases). Bitcoin is the most popular cryptocurrency and ever since its release in 2009, enthusiasts have created 4,000+ alternative variants of bitcoin and other cryptocurrencies. Cryptomining involves verifying and adding crypto transactions to the blockchain digital ledger and we have compiled a list of the best 8 apps you can use for the task.
