Bitcoin segwit activation
There are thousands of different cryptocurrencies in existence today, but bitcoin is still king. In , code that was intended to lead to the activation of a Bitcoin improvement known as Segregated Witness SegWit was made available via a new release of Bitcoin Core. At the time, this was mainly viewed as nothing more than a technical upgrade although there was some disagreement regarding how the upgrade should be implemented that would bring a variety of benefits to the network , including laying the foundation for layer-two payment protocols like the Lightning Network. However, the activation of this seemingly innocuous technical improvement eventually became highly politicized. This politicization of SegWit was recently discussed during a panel at the Understanding Bitcoin conference in Malta. The two main scaling proposals at the time were 1 a user-activated soft fork UASF of SegWit via Bitcoin Improvement Proposal BIP or 2 a combination of a soft fork activation of SegWit once 80 percent of the network hashrate had signalled their readiness for the improvement combined with a hard-forking increase to the block size limit.

The cryptocurrency market saw sheer panic over the prospects of a possible hard fork event and a Bitcoin blockchain split, resulting in two Bitcoins with separate blockchains and a possible loss of Bitcoin value on one of the two blockchains. Calmness has been restored for now, with the Bitcoin exchanges playing a more active role in driving support in favor of what is considered to be the best outcome for Bitcoin and stability within the cryptocurrency world.
Support for the coding of SegWit2x has eased in recent weeks, with the general consensus being that the timing is wrong for the activation, production and implementation of the code, the community believe that there had been inadequate testing coupled with an unrealistic timeline for implementation.

The Bitcoin world all too aware of what a hard fork blockchain split would mean for the integrity of Bitcoin and other Cryptocurrencies.
Such an outcome nullifying BIP If BIP91 is not activated by this date, the probability of a blockchain split increases significantly, leaving holders of Bitcoin and miners 2-days to prepare for the split, with miners having until 1 st August to decide on which blockchain to mine, the legacy blockchain or the BIP Chain.
If a blockchain split has been avoided until now, there are more dire consequences for Bitcoin, which could see the creation of multiple Bitcoins, which include the legacy, , ABC and possibly a 4 th , depending on support levels for the various forks. Not only is it a confusing set of possible scenarios and outcomes, timelines are ever changing, which could leave holders of Bitcoins out in the cold, if the blockchain split happens early. Vigilance is needed and volatility will be the story of the day, the worse possible outcome for now being any hint of a blockchain split, now or months down the road.
A meteoric rise in popularity for cryptocurrencies and Bitcoin in particular, has led to an ongoing debate and increasing level of disagreement between miners and core developers on how Bitcoin should move forward.
Core developers have been looking at how Bitcoin software can be adapted to accommodate for the ever increasing number of transactions and also meet the rising demand for Bitcoins, the unprecedented returns continuing to drive demand, fears of a Bitcoin bubble having eased in recent months.
The debate has ultimately created a lot of hype and the threat of derailing Bitcoin and other cryptocurrencies, with Bitcoin prices in recent months reflective of how the debate heated up and progressed through to the current support for BIP In fact, the debate became so intense that the chances of a Bitcoin fork split had become almost probably just a week ago, the prospect of two Bitcoin blockchains expected to, not only lead to issues as a result of the co-existence of two ledgers, but also the possibility of Bitcoins actually disappearing, leaving holders of the coins with empty wallets, all of which would be a prelude to an even more heated debate over which blockchain would be considered the real Bitcoin going forward, for those left standing.
As things stand, Bitcoin blocks have a storage capacity of 1MB. The increased level of congestion has led to lengthening transaction verification timeframes and rising transaction fees. Both sides proposed solutions on how to resolve the issues faced, with neither side being able to come to an agreement on a preferred solution going forward, leading to the great divide. The decentralized nature of Bitcoin has made the disagreement public and not behind the closed doors of a boardroom that would be common within the corporate world.
BIP requires that miners signal for SegWit readiness, which is achieved by miners setting the version of blocks mined, essentially affirming miner support for the rules of SegWit. Bitcoin Unlimited : As the name suggests, the solution is to deliver miners the freedom to increase blockchain size, which would remove the congestion issues and transaction times and fees faced by miners today.
Segregated Witness, referred to as SegWit, is the process of addressing the limit of an increase in the block size limit by removing signature data from the transactions, which eases capacity issues enabling more transactions and increasing verification speeds. Transaction inputs and outputs are duplicated across the nodes, the input being the public address of the sender, with the output being the public address of the recipient. The input data leads to the biggest capacity issues, with input data including signatures, which forms part of the verification process on the sender having the required funds to make payment, the information being included in the active block and then the general ledger.
As more transactions occur and more blocks are created, the 1MB maximum size of each block limits the number of transactions per block. SegWit looks to shift the signature component from the input phase to the end of the transaction, which is estimated to increase the 1MB block size limit to slightly below 4MB.
The issues facing Bitcoin boil down to the possibility of both a soft and hard fork, which has raised the alarm bells amongst some holders of Bitcoin over the safety and valuation of holdings on various exchanges.
There has been a lot of talk and speculation of what is likely to take place on 1 st August, with news of increased support for two proposals in particular, raising the possibility of a Bitcoin blockchain split, leading to two versions of Bitcoin running on separate blockchains.
The difference between a UASF and UAHF is that a soft fork is a temporary divergence in the blockchain create by non-upgraded nodes not following new consensus rules, whilst a hard fork is a permanent divergence in the blockchain. While a blockchain split may be averted, the reality remains that the positives of establishing cryptocurrencies and a decentralized virtual currency have been lost to a certain extent, with a handful of mining pools garnering such sizeable hashrates that has led to what some will refer to as the Bitcoin Cartel, in stark contrast to the ethos of a decentralized virtual currency and more akin to the push and pull seen between central banks and governments, independence continuously being questioned.
Until miners entering the fray embrace the entire concept of decentralization and support the smaller mining pools and cloud mining service providers, the Cartel will continue to influence and ultimate control will reside with a few.
The days ahead are certainly of particular importance to the direction of Bitcoin and cryptocurrencies in general, over the short-term, but in reality there is only one event that needs to be averted and that is a blockchain split, other coding changes unlikely to have a material impact on valuations for now. By : Bob Mason. Most Popular. Natural Gas. Some key dates through the end of August include: 23 rd July: BIP91 anticipated to be activated, if the majority of miners enforce BIP91 for the next 2-weeks.

Segregated Witness abbreviated as SegWit is an implemented protocol upgrade intended to provide protection from transaction malleability and increase block capacity. SegWit separates the witness from the list of inputs. The witness contains data required to check transaction validity but is not required to determine transaction effects. Additionally, a new weight parameter is defined, and blocks are allowed to have at most 4 million weight units WU. Non-witness and pre-segwit witness bytes weigh 4 WU, but each byte of Segwit witness data only weighs 1 WU, allowing blocks that are larger than 1 MB without a hardforking change.

SegWit was activated in August after being put forward by Bitcoin developer Peter Wiulle during a Scaling Bitcoin conference in It also provides a security fix, as the input transaction ID could be modified to fraudulently receive Bitcoin from the sender. However, as SegWit2x required a hard fork and was a more fundamental change to the Bitcoin protocol, the developer community could not reach consensus and ultimately the proposal was abandoned.

Bitcoin Avoided a Fork with One "Awesome" "Positive Change"
Bitcoin's record high marks a percent year-to-date rise and comes after months of infighting in the cryptocurrency world. Within the bitcoin community, a so-called "scaling debate" has been going on. There is a big backlog of transactions on the bitcoin blockchain — the technology that underpins the cryptocurrency. The debate was over the way in which the capacity of the blockchain could be increased to speed up the capability of the bitcoin network. Major infighting within the community took place which led to two separate proposals on how to expand the blockchain.
Segregated Witness (SegWit)
Soft fork activation describes the moment when a Bitcoin full node begins to enforce one or more additional consensus rules. These transitions introduce a coordination risk between nodes on the network, so developers have devoted much effort over the years to creating and improving soft fork activation mechanisms that can minimize the chance a problem will occur. Soft forks allow the overall network to transition to new consensus rules even if not every node has adopted those rules. This is the main problem that activation mechanisms attempt to mitigate. Proposals for new soft fork activation mechanisms are often designed to avoid problems experienced during previous soft forks, so this section attempts to provide an overview of notable past activation attempts.
