Segwit To Activate Within 24 Hours, How Bitcoin Will Change

Segregated Witness (SegWit) to Activate Within 24 Hours: How Bitcoin Will Change Join our community of 10 000 traders on Hacked.com for just $39 per month. Segregated Witness (SegWit), the Bitcoin Core development teams transaction malleability fix and scaling solution, is set to activate within the next 24 hours. Major bitcoin companies including European bitcoin payment processing startup Bitwala are hosting SegWit celebratory events to commemorate bitcoins first milestone in scaling. Many celebratory events are being held across the globe. According to Bitwala, seven events will be held on August 23 in Germany, Slovakia, the US, Switzerland, Poland, Czech Republic, and France. The activation of segregated witness is a huge milestone in the development of Bitcoin. A step which enables a literal explosion of cool new features enhancing scalability, fungibility, privacy and usability of our favourite money, said the hosts of the SegWit activation party led by Bitwala. Short Summary of the Past 12 Months in Scaling Debate Since 2016, the bitcoin industry and the mining community have debated on whether to activate SegWit. The majority of companies in the bitcoin industry advocated for an unconditional activation of SegWit, while mining pool operators including Bitmain, ViaBTC and Bitcoin.com opted for a conditional activation of SegWit called SegWit2x. Proposed and led by the Digital Currency Group-led consortium of 57 companies, SegWit2x calls for the activation of SegWit given the guarantee that the bitcoin block size will be increased to 2MB. In late July, the bitcoin industry and mining community came to a consensus to activate SegWit via BIP 91, which many analysts described as the last opportunity to prevent the execution of a hard fork. Ultimately, SegWit was act Continue reading >>

Where Can You See Current Bitcoin Miners Signalling Segwit2x?

Where Can You See Current Bitcoin Miners Signalling Segwit2x?

Where can you see current Bitcoin miners signalling SegWit2x? Hi I know you can view current miners signalling 'intent' to implement SegWit2x on coindance . But is there a live website that show miners actually signalling SegWit2x? Blocks signalling for the SegWit2x, i.e. the New York Agreement segwit activation (BIP91), are setting bit4. This shows up as a '1' in the second to last position of the version field. Blocks signalling readiness for BIP141, i.e. regular segwit activation, do so on bit1 which shows up as '2' in the last position of the version field. It is also possible to signal readiness for both: 20000010 20000002 20000012 bit4 bit1 bit4 and bit1 xbt.eu is explicitly tracking the bit4 signalling already, but you can see the version field for blocks on most block explorers, and sites that track such information such as coin.dance . Note: Bit 4 refers to 1<<4 and is thus the fifth bit from the back because the first is Bit 0. ;) Continue reading >>

Countdown To Segwit: These Are The Dates To (still) Keep An Eye On

Countdown To Segwit: These Are The Dates To (still) Keep An Eye On

Countdown to SegWit: These Are the Dates to (Still) Keep an Eye On Bitcoins very public scaling debate is entering a crucial phase. Two of the most popular scaling proposals available today BIP148 and SegWit2x both intend to trigger Segregated Witness (SegWit) activation within a month, which means that the protocol upgrade could be live within two. At the same time, there is a very real risk that Bitcoin splits. Both BIP148 and SegWit2x could diverge from the current Bitcoin protocol, which could in turn lead to even more splits. Here is a list of dates for July, August and beyond to keep an eye on. This article was last updated on August 8th. August 2nd update: Most of the information in this section is still accurate, but some of it is a bit outdated now. Keep in mind it was written about a month ago, before many of the recent developments occurred. First, a brief recap on Segregated Witness and its potential activation methods. SegWit is a backwards compatible protocol upgrade originally proposed by the Bitcoin Core development team. It has been a centrepiece of the scaling roadmap supported by Bitcoin Core since the protocol upgrade was first proposed in December 2015, and it is implemented on many active Bitcoin nodes on the network today. SegWit is now also part of the New York Agreement : an alternative scaling roadmap forged between a significant number of Bitcoin companies, including many miners. And Bitcoin Improvement Proposal 148 , or BIP148, is a user activated soft fork (UASF) scheduled for August 1st that also intends to activate SegWit. The difference lies in how the activation should happen. The first and original option was proposed by the Bitcoin Core development team. Their SegWit code, defined by BIP141 , activates if 95 percent of hash power with Continue reading >>

Peter Todd: Wait For 6 Confirmations After Bip 91 Activates

Peter Todd: Wait For 6 Confirmations After Bip 91 Activates

Peter Todd: Wait For 6 Confirmations After BIP 91 Activates Peter Todd, highly regarded Bitcoin Core developer and well-respected cryptography consultant, encourages users not to accept transactions with one confirmation when BIP 91 activates. Peter Todd, the highly regarded Bitcoin Core developer and well-respected cryptography consultant, encourages users not to accept transactions with one confirmation when BIP 91 activates. At the time of reporting, on July 18, it has become quite evident that the mining and development communities have come to a consensus to adopt Bitcoin Improvement Proposal (BIP) 91 or miner-activated soft fork to activate the Bitcoin Core development teams transaction malleability fix and scaling solution Segregated Witness (SegWit). Mounting pressure from both user activated soft fork (UASF) and the Digital Currency Group-led SegWit2x, also known as the Silbert Accord, has pushed miners to opt for BIP 91, which activates SegWit at a threshold of 80 percent. Essentially, BIP 91 was the last option for the mining community to avoid the execution of a chain split-resulting hard fork and the community took it. The community, businesses, users and investors have wanted the activation of SegWit and scaling of the Bitcoin Blockchain for awhile. However, like any changes, the soft fork execution of BIP 91 to activate SegWit should be handled with caution by both developers and users. Todd explained that a high probability exists for the activation of SegWit via BIP 91 which will lead to multiple reorganizations. Amidst such change, Todd noted that users should only accept transactions with six confirmations for security purposes. More Warning: if/when BIP 91 activates, there's a high chance it'll lead to multiple reorganizations. Do not trust one conf Continue reading >>

Segwit Activated: How It Works & Whats Next For Bitcoin

Segwit Activated: How It Works & Whats Next For Bitcoin

Segregated Witness, or Segwit, has finally been activated by a super majority of the current hashpower on the Bitcoin network. Segwit fixes many bugs currently in the protocol, and allows for some scaling using an effective blocksize increase. In December of 2015, the source code for Segregated Witness (Segwit) was released. It was meant as a fix for the ever-problematic transaction malleability bug, which allowed for someone to change one or two characters of a transactions ID before it was cemented into the blockchain. Along with that, it provided a method of scaling Bitcoin. Doing away with the concept of a blocksize, a new metric was made called blockweight. For years the software was not added to the Bitcoin protocol as it never garnered the necessary 95% of the hashpower needed to activate. It was to be implemented though means of a softfork, which meant it would comply with all currently consensus rules and be backwards compatible with those running old software and did not wish to upgrade. Whether you believe that Segwit was a direct result of the grassroot approach of BIP148 forced miners to finally activate it after all this time, or the New York Agreement was the reason everyone came together to signal for Segwit, it is finally here. A second BIP was released weeks ago to lower the activation threshold to 80% of the hashpower, but even with the lowered bar Segwit still achieved around 97% signaling and locked in during the beginning of August. After the official lock-in period, the network allowed for two weeks to provide grade period of sorts for people to upgrade their software to work with Segwit. There has been a ton of misinformation about Segwit, so this article will hopefully clear some things up of how it actually works. As stated earlier the whole i Continue reading >>

Segwit Goes Live: Why Bitcoin's Big Upgrade Is A Blockchain Game-changer - Coindesk

Segwit Goes Live: Why Bitcoin's Big Upgrade Is A Blockchain Game-changer - Coindesk

SegWit Goes Live: Why Bitcoin's Big Upgrade Is a Blockchain Game-Changer That's when Segregated Witness (SegWit) will activate on bitcoin late today or tomorrow morning, bringing the years-longdebate over the contentious code upgradeto an official close. At that time, users will finally be able to take advantage of the long-promised technology. Looking back, it's important to note how long the change perhaps the biggest ever made to the bitcoin software has taken. To start, the community has been embroiled in politics since SegWit was first proposed in 2015 by Bitcoin Core contributor Pieter Wuille as a possible "compromise" to the scaling debate. Since then, there's been no shortage of drama mining firm Bitmain was accused of blocking SegWit in order to boost its revenue; major bitcoin companies and mining pools united behind their own scaling plan ; and finally, unhappy with the plan, users equipped with GIFs and branded hats responded with a kind of revolt . But with SegWit soon to be guaranteed, today marks the first day it will be usable on bitcoin. Here are the key thingsthat SegWit enables: It rearranges how data is stored in bitcoin blocks. It boosts capacity while remaining compatible with past versions of the software. It removes transaction malleability, a bug that's been the primaryroadblock for many bitcoin projects. The final point is what might have the most lasting impact. Indeed, many developers believe SegWit will boost the development of more forward-looking technologies necessary for bitcoin's mainstream use. The best known is the Lightning Network, first proposed in a 2015 white paper by Joseph Poon and Tadge Dryja. The idea is payment channels that move transactions off the blockchain could boost bitcoin's capacity to millions of transactions per Continue reading >>

Bitcoin Price Stable Following Segwit Activation

Bitcoin Price Stable Following Segwit Activation

Bitcoin Price Stable Following SegWit Activation Join our community of 10 000 traders on Hacked.com for just $39 per month. The Segregated Witness (SegWit) soft fork activated last night, initiating significant changes to the bitcoin protocol. The bitcoin price experienced a slight uptick following the SegWit deployment, stabilizing its single-day performance. The wider markets saw a minor pullback from Wednesdays record $154 billion , but several altcoinsincluding litecoin, managed to press forward. For most of August 23, the crypto market cap hovered between $150 billion and $155 billion. However, Wednesday evening it dipped to $148 billion. It recovered early Thursday morning, and the total value of all cryptocurrencies currently sits at $151.8 billion. Bitcoin Price Stable Following SegWit Activation The bitcoin price did not see an immediate bump upon SegWit activation, but it did more or less retain its midweek rally. For the day, the bitcoin price declined a bit less than 1% and currently rests at $4,181. This gives bitcoin a market cap of $69 billion. Many analysts anticipate that SegWit will cause the bitcoin price to punch through $5,000 by the end of the year, while stock researcher Ronnie Moas forecasts it could rise as far as $7,500. However, the future of the bitcoin price will depend on how the community grapples with the increasingly-heated debates over the November SegWit2x hard fork. The ethereum price declined about one-half of a percent on Thursday, holding above $320 as the Metropolis hard fork approaches. At present, the ethereum price is $321, which results in a $30.2 billion market cap. The Metropolis protocol upgrade is highly-anticipated among the community, and many expect the ethereum price to break above $350 as it nears. The bitcoin cash p Continue reading >>

Bitcoin Network Locks In Segwit Activation, But What Is Next?

Bitcoin Network Locks In Segwit Activation, But What Is Next?

Bitcoin Network Locks in SegWit Activation, but What is Next? The long wait is finally over for a lot of Bitcoin users. More specifically, the network has successfully locked-in SegWit activation. This software upgrade has caused a fair bit of debating but is mainly seen as a positive development. There is still a two-week waiting period before it effectively activates, though. The bigger question is what will be next for the Bitcoin network. Many speculators expect a massive price surge, but things often play out very differently. Successfully locking in SegWit activation is a big first step. Considering how this upgrade was deployed nearly a year ago, the consensus comes right on time. More specifically, it had a one-year deployment up until November. Despite a lot of opposition along the way, we now have a consensus. All of the blocks mined during this previous activation method signaled SegWit support. That is rather uncommon in the Bitcoin world, to say the least. However, this is still only the first step toward achieving the goal we have been waiting for. SegWit Lock-in has Been Secured Successfully To be more precise, there is a two-week grace period before full activation. Once that locks in, miners cannot change their mind about Segregated Witness any longer. Until then, they can still switch to other solutions if they prefer to do so. Once the course is set, things are locked in place for the foreseeable future. Additionally, some miners still need to upgrade their software before August 22. It is good to see the Bitcoin network receive a scaling solution which can provide many different new features. Perhaps the biggest change is the transaction malleability fix. It is an important part of SegWit that shouldnt be overlooked by any means. Other benefits incl Continue reading >>

Samourai Wallet Intends To Run Bip 148 Until Segwit Is Fully Activated

Samourai Wallet Intends To Run Bip 148 Until Segwit Is Fully Activated

Samourai Wallet Intends to Run BIP 148 Until SegWit is Fully Activated Samourai Wallet, one of the most innovative privacy-focused wallet service providers in the market, intends to run Bitcoin Improvement Proposal BIP 148 until SegWit is activated Samourai Wallet, one of the most innovative privacy-focused wallet service providers in the market, intends to run Bitcoin Improvement Proposal BIP 148 until the Bitcoin Development teams transaction malleability fix and scaling solution Segregated Witness (SegWit) is fully activated. The Bitcoin community and industry have come significantly closer to the activation of SegWit. However, as Bitcoin Core developer and well-respected cryptography consultant Peter Todd explained earlier this week, the lock-in of BIP 91 , a kludge-like solution between BIP 141 (original SegWit proposal) and SegWit2x, does not necessarily mean that SegWit activation is completely finalized as of yet. At the moment, contrary to most expectations, the mining community is fully signaling their intent to activate BIP 141, the safest and the most efficient way to activate SegWit according to Todd. In fact, according to various sources and block analysis platforms such as Coin Dance, SegWit activation via BIP is close, but not quite there yet. Jameson Lopp, an engineer at BitGo, a leading multi-signature and security services provider, states: SegWit is not activated on Bitcoin yet. It will take several more weeks to lock in SegWit, then a couple more to activate it. Since the initial 80 percent hashrate threshold was met on July 16, Bitcoin price has increased from $1,850 to $2,860. Although Bitcoin had a major correction, it remains relatively high at $2,740. Such a rapid increase in pricing in a short period demonstrates the trust investors, traders, Continue reading >>

It's Official: Segregated Witness Will Activate On Bitcoin - Coindesk

It's Official: Segregated Witness Will Activate On Bitcoin - Coindesk

It's Official: Segregated Witness Will Activate on Bitcoin Segregated Witness (SegWit) has reached its lock-in threshold. The long-debated scaling upgrade reached the necessary threshold to "lock in" today at block 479,707 with 100% of bitcoin mining pools signaling support for theproposal.According to network data, the block was mined by BitClub. But the change won't officially lock-in until tomorrow, once the signaling period has ended. Further, the change will be unusable, as CoinDesk described in more depth , for a couple more weeks. The network will moveinto a roughly two-week "grace period," to give users and mining pools a chance to upgrade their software. After that, which looks to end August 21, SegWitwill activate and miners will start rejecting blocks that do not support the change. First proposed by bitcoin developer Pieter Wuille in December 2015, the expectation for SegWit is that it will open up several ways to scale bitcoin to support more users. While this doesn't seem particularly contentious, it has been the subject of tireless debate within the bitcoin community. Other communities such as litecoin managed to activate it last spring. But today, the SegWit loop has been closed for bitcoin. Continue reading >>

Segwit - Wikipedia

Segwit - Wikipedia

Segregated Witness, or SegWit, is the name used for an implemented soft fork change in the transaction format of the cryptocurrency Bitcoin which has also been implemented on currencies such as Litecoin , DigiByte and Vertcoin . The formal title "Segregated Witness (Consensus layer)" had Bitcoin Improvement Proposals number BIP141. [1] It is intended to solve a blockchain size limitation problem that reduces Bitcoin transaction speed. It does this by splitting the transaction into two segments, removing the unlocking signature ("witness" data) from the original portion and appending it as a separate structure at the end. [2] The original section would continue to hold the sender and receiver data, and the new "witness" structure would contain scripts and signatures. The original data segment would be counted normally, but the "witness" segment would, in effect, be counted as a quarter of its real size. Bitcoin is a cryptocurrency, a form of money using cryptography to keep transactions secure. [3] Each record of a unit of Bitcoins is called a "block", and all blocks are tied together sequentially by using a cryptographic hash on the previous block and storing in the next. This forms a chain of blocks, or a blockchain. [4] Each block of bitcoins contains information about who sends and receives a given unit of bitcoin (a transaction), as well as the signature that approves each transaction. Originally, there was no limit to the size of these blocks. But this meant that malicious people could make up fake "block" data that was very long as a form of Denial of Service (DoS) attack. Their fake blocks would be detected, but doing so would take a very long time, slowing down the whole system. [5] The solution Satoshi designed was to put a limit on block size, which was 1 MB Continue reading >>

Segregated Witness Activates On Bitcoin: This Is What To Expect

Segregated Witness Activates On Bitcoin: This Is What To Expect

Segregated Witness Activates on Bitcoin: This is What to Expect The Segregated Witness (SegWit) soft fork has activated on the Bitcoin network. As of block height 481,824, found at 1:57 UTCby BTCC, all SegWit ready nodes started enforcing the new SegWit consensus rules. As Bitcoins biggest protocol upgrade to date, this introduces a whole new data structure, which changes the appearance of Bitcoin blocks for upgraded nodes while non-upgraded nodes should continue to function as normal. More concretely, SegWit activation means that Bitcoins block size limit is replaced by a block weight limit, which allows for blocks up to 4 megabytes in size. Additionally, and perhaps more importantly, SegWit transactions wont suffer from the malleability bug , which in turn enables advanced second-layer protocols like the Lightning Network, atomic swaps, MAST, and more. Heres what to expect for the next couple of hours, days, weeks, months and beyond The Block Size Limit Becomes a Block Weight Limit Bitcoin blocks now have a weight limit instead of a size limit.Depending on the types of transactions included, this means that blocks can get up to 4 megabytes big though some 2 megabytes is a more realistic maximum. This should decrease network fees for users, and speed up transaction confirmation times. However, this doesnt mean that all blocks will immediately bump to 2 megabytes in size today. For a transaction to utilize the added space, it must be sent from a SegWit address (or more accurately, a Segwit output) not just to a SegWit address. At the time of activation, of course, no bitcoins were locked up in SegWit addresses whatsoever. That wasnt possible up till now. So at the very least, bitcoins must be spent once to a SegWit address once first. Only when theyre spent again will Continue reading >>
