The Great Bitcoin Scaling Debateatimeline

The Great Bitcoin Scaling Debate ATimeline Why have so many attempts to scale Bitcoins blockchain failed? This timeline chronicles the repeated attempts to scale Bitcoins blockchain, and details how each attempt has so far been unsuccessful. It covers all important dates in the scaling debate, focusing on how and why alternative implementations of Bitcoin have sprung up in an effort to scale the blockchain to a larger block sizes. A brief overview of why the block size of 1 MB has never increased: Efforts to increase the block size of Bitcoin began with appeals from developers like Gavin Andresen, Jeff Garzik, and Mike Hearn as early as 2011. They anticipated a time when the rate of transactions would exceed the available space in blocks and sought to increase the block size limit a change that might seem straightforward. The block size was put in place to limit the possibility that someone could cheaply spam the network. Sending a large number of transactions was cheap, and it would have been possible to crowd out other transactions for a small investment . The spam control mechanism persists in the form of the block size limit of 1 MB, which in turn limits the transactions per second on the network to about three. While every effort to scale Bitcoin has so far failed for a variety of reasons, what they were seeking to accomplish is still a problem that needs fixing. Developers working on Bitcoins main Github repository agree that a block size increase needs to happen, but they have not yet established a way to do this with broad consensus. And they seem to have given up trying for a hard fork block size increase, working towards off-chain solutions that do not require the building of network-wide consensus. The most recent attempt to increase the base block size of B Continue reading >>

How Good Is Litecoin's Development Team Relative To Bitcoins? - Quora

How Good Is Litecoin's Development Team Relative To Bitcoins? - Quora

How good is Litecoin's development team relative to Bitcoins? Answered Nov 11, 2017 Author has 597 answers and 854.4k answer views Here are the top 10 coins as Coingecko has it, which rates them according to the metrics in the table here. With regard to developers, Coingecko states that: CoinGecko tracks the development activity of the coins via public source code repositories. The reason why we are looking at this is that some coins are no longer maintained by the developer thus those coins would appear very unlikely to progress over time. By looking at how much interest and effort goes around the development community, there is a chance that the coin will continue to innovate according to how the cryptocurrency market sees fit. So you can see here that Litecoin actually scores pretty lowly for developers in this top 10, but the thing is, Litecoin is a fork of Bitcoin, so a lot of the developments from Bitcoin are used on Litecoin, and when you look at the Github commits, you will see a lot of the Bitcoin Core developers on the Litecoin page because their commits are transferred over. Litecoin has a great developer team, but is relatively small. The Litecoin Foundation aims to raise $200,000 annually to pay its developers, which is a fraction of what some of the ICOs are looking to raise. Bitcoin though, dominates the market for cryptography experts, as one might expect from its position on the throne of cryptocurrencies. Bitcoin Core is the biggest, most active developer team in the cryptosphere, probably partly because it is the longest running. The Core development team is completely open sourced, and anyone can suggest updates to the Bitcoin software, which the community will look at, and accept if there is consensus. Litecoin has a smaller team, but that doesnt m Continue reading >>

Bitcoin Core Developers Issue Segwit2x Hard Fork Warning

Bitcoin Core Developers Issue Segwit2x Hard Fork Warning

Bitcoin Core developers issue Segwit2x hard fork warning Luke Parker , 12 Oct 2017 - Bitcoin , Development , Segwit2x On Wednesday morning, the Bitcoin Core development team released a rare statement concerning the safety of Bitcoin users coins during the potential hard fork for Segwit2x , which is scheduled to occur in November. The developers state that the hard fork is not supported by the majority of the Bitcoin users and developers, which makes it contentious, and therefore puts many user's bitcoins at risk if they store them with the wrong services. By adopting this hard fork, the announcement states, we believe the supporters of this agreement are shifting their users to an alternative currency (an altcoin) which is incompatible with Bitcoin. Bitcoins developers strongly advise against storing coins on services such as Coinbase, Bitpay and Xapo since the coins may be renamed to something else or replaced with a new altcoin that is not bitcoin. Currently, 43 services intend to leave bitcoin for the new blockchain (the complete list can be obtained here ). By adopting this hard fork, we believe the supporters of this agreement are shifting their users to an alternative currency which is incompatible with Bitcoin." The major difference in the Segwit2x hard fork that sets it apart from many previous hard forks such as the one for Bitcoin Cash in August is that many major bitcoin infrastructure providers including wallets and exchanges support this fork. A majority of bitcoin mining hashrate is in support of the fork as well, which at the very least will slow down the production of bitcoins blocks as the miners fork the blockchain and depart bitcoin in favor of mining the new chain. The rate that block production will slow down to is unknown, however, it is currently Continue reading >>

Bitcoin Core - Wikipedia

Bitcoin Core - Wikipedia

(November11, 2017; 33 days ago(2017-11-11)) Bitcoin Core is the reference client of bitcoin . Initially, the software was published by Satoshi Nakamoto under the name Bitcoin, and later renamed to Bitcoin Core to distinguish it from the network . [1] For this reason, it is also known as the Satoshi client. [2] It is the reference implementation for bitcoin nodes, which form the bitcoin network. Through changes to Bitcoin Core, its developers make changes to the underlying bitcoin protocol. [3] As of 2016 [update] , Bitcoin Core repositories are maintained by Wladimir J. van der Laan. [4] The MIT Digital Currency Initiative funds some of development of Bitcoin Core. [5] The project also maintains the cryptography library libsecp256k1. [6] Bitcoin Core includes a transaction verification engine and connects to the bitcoin network as a full node . [2] Moreover, a cryptocurrency wallet , which can be used to transfer funds, is included by default. [6] The wallet allows for the sending and receiving of bitcoins. It does not facilitate the buying or selling of bitcoin. It allows users to generate QR codes to receive payment. The software validates the entire blockchain , which includes all bitcoin transactions ever. This distributed ledger which has reached more than 130 gigabytes in size must be downloaded or synchronised before full participation of the client may occur. [2] A command line -based daemon with a JSON-RPC interface, bitcoind, is bundled with Bitcoin Core. It provides access to testnet, a global testing environment that imitates the bitcoin main network or Mainnet. It uses an alternative blockchain where real bitcoin are not used and the blockchain cannot be adversely affected. Regtest or Regression Test Mode creates a private blockchain which is used as a loc Continue reading >>

Charlie Lee Wants To Test A New Solution For Bitcoin Fee Estimation On Litecoin

Charlie Lee Wants To Test A New Solution For Bitcoin Fee Estimation On Litecoin

Charlie Lee Wants to Test a New Solution for Bitcoin Fee Estimation on Litecoin Litecoin, which is an altcoin that has long been marketed as the silver to bitcoins gold, was not the most difficult thing for creator Charlie Lee to launch. He simply took the Bitcoin Core codebase, changed a few parameters (such as the block time and mining algorithm), and then posted the new creation on bitcointalk.org. More than six years after this initial launch, this close relationship to the code found in Bitcoin Core, which is effectively the reference implementation of the Bitcoin protocol, has become one of Litecoins greatest strengths. After selling off the rest of his litecoin holdings , Lee is now focused on development around the base Litecoin protocol. While Bitcoins little brother did not need much in terms of its own development team in the past, the platform is now used as a way to test features that may eventually find their way onto the Bitcoin network. Although it was originally thought that Litecoin would be a testbed for features that are already planned for eventual inclusion on the Bitcoin network, Lee is now prepared to implement some of his own ideas on Litecoin. Litecoins Close Relationship with Bitcoin Instead of doing much of their own development, Litecoin developers have relied almost entirely upon the work done by contributors to Bitcoin Core up to this point. Instead of writing their own code, the Litecoin development would routinely rebase the changes made in Bitcoin Core onto the reference implementation of Litecoin. This allowed Litecoin to enjoy the same level of security and stability seen in the development of Bitcoins codebase, while also maintaining those tweaked settings included in the original release of the altcoin. In fact, the codebase and fe Continue reading >>

The Big Bitcoin Battle: What I Found Out About Bitcoin Vsbcash

The Big Bitcoin Battle: What I Found Out About Bitcoin Vsbcash

The Big Bitcoin Battle: What I Found Out About Bitcoin VSBCash UPDATE: Since I last posted this a few days ago, the Segwit2X fork had a fatal error that doomed its implementation. If Bitcoin had adopted it, it would have been a catastrophic failure costing tens of billions of dollars. This is the very reason why I focused on the competence of the development team and engineers in this piece. The last several days have been quite the roller coaster ride for Bitcoin and Cryptocurrency holders. If you are new to this, fix your hair, have a sip of water, walk it off a little bit, then settle down and grab a seat. If you are a grizzled veteran, youre likely a bit excited about the free fall (after months of going up, up, up) and your heart rate is probably a bit elevated, but nothing to lose sleep over you know Bitcoin will be fine after the dust settles. One thing that has been proven time and time again in the last 8 or so years is this: Bitcoin is not resilient or resistant to attacks. Bitcoin is much more than that Bitcoin is Anti-fragile. Antifragility is a property of systems that increase in capability, resilience , or robustness as a result of stressors, shocks, volatility, noise, mistakes, faults, attacks, or failures. Bitcoin has come out stronger after every attack on the system and this is no different from past attacks, nor will this be the last attack on the Bitcoin network. So what is happening, you might ask? Simply put, the people running Bitcoin Cash are plotting the death of Bitcoin by launching a coordinated attack on the Bitcoin network. Why would they want to do this instead of just making a better version that people will actually want to use, and beat Bitcoin fair and square in the market? Did the Bitcoin Core team force their hand into doing somethi Continue reading >>

Do not use URL shortening services: always submit the real link. Begging/asking for bitcoins is absolutely not allowed, no matter how badly you need the bitcoins. Only requests for donations to large, recognized charities are allowed, and only if there is good reason to believe that the person accepting bitcoins on behalf of the charity is trustworthy. News articles that do not contain the word "Bitcoin" are usually off-topic. This subreddit is not about general financial news. Submissions that are mostly about some other cryptocurrency belong elsewhere. For example, /r/CryptoCurrency is a good place to discuss all cryptocurrencies. Promotion of client software which attempts to alter the Bitcoin protocol without overwhelming consensus is not permitted. Trades should usually not be advertised here. For example, submissions like "Buying 100 BTC" or "Selling my computer for bitcoins" do not belong here. /r/Bitcoin is primarily for news and discussion. Please avoid repetition /r/bitcoin is a subreddit devoted to new information and discussion about Bitcoin and its ecosystem. New merchants are welcome to announce their services for Bitcoin, but after those have been announced they are no longer news and should not be re-posted. Aside from new merchant announcements, those interested in advertising to our audience should consider Reddit's self-serve advertising system .

Bitcoin Core Releases Software Upgrade With Full Segwit Support

Bitcoin Core Releases Software Upgrade With Full Segwit Support

Bitcoin Core Releases Software Upgrade With Full SegWit Support Feb 26, 2018 at 18:00 UTC|UpdatedFeb 27, 2018 at 03:04 UTC The Bitcoin Core development team has released a much-anticipated software upgradedesigned to help scale the cryptocurrency network. Version 0.16.0 of Bitcoin Core, the standard software client of the bitcoin network, adds full support for Segregated Witness (SegWit). Itsrelease was presaged by a Github announcement earlier in February. "Bitcoin Core 0.16.0 introduces full support for segwit in the wallet and user interfaces," said a statement circulated Monday on a Linux Foundation mailing list. The code is intended to solve bitcoin's scalability obstacles. Bitcoin's main protocol has a maximum block size of 1 megabyte, which restricts the volume and speed of transactions. By separating signature and transactional data, SegWit reduces the "weight" of transactions, which creates more room in any given block. This does not increase the network's block size limit, but it does increase the volume of possible transactions. The removal of the signature information also resolves the problem of transaction malleability , which was previously a security vulnerability because transaction IDs could be altered. Likewise, this impeded the implementation of second-layer protocols such as the Lightning Network. SegWit also introduces a new address format created by Bitcoin Core contributors Pieter Wuille and Greg Maxwell that provides a better user experience, facilitates the automatic support of SegWit and lowers transaction fees. Introduced in November of 2016, SegWit has seen slow adoption amid the controversy over the block size limit. Major crypto exchanges have recently moved to support SegWit, including GDAX and Bitfinex, however. "SegWit provides not onl Continue reading >>
