Coinbase have announced thatthe site will now be implementing SegWit on Bitcoin deposits and withdrawals.
The transition is being implemented overthe coming week, and should improve transaction speeds and lowerfees. SegWit was introduced Augustof last year through BIP 141 (Bitcoin Improvement Proposal), however Coinbasewas slow to adopt the technology. The lack of implementation of the technologywas increasinglyfrustrating for Coinbase users, who launched a petition callingfor the exchange platform to prioritize SegWit implementation over otherupgrades. The petition noted that the Bitcoin community is “overwhelmingly insupport” of SegWit, and was signed over twelve-thousand times.
Segregated Witness or SegWit was a majorimprovement to the Bitcoin protocol. By redefining the structure of blocks,(with one block changing from 1MB to become four million units) it becamepossible to greatly reduce the space taken on the blockchain by transaction andwitness data. The change allowed more transactions to be stored in each block,making the blockchain more efficient and cheaper to use.
Coinbase is not alone in recentlyadopting the technology. Last week the Bitcoin Core wallet upgraded toallow SegWit Transactions, which was followed by an announcement from Bitfinexthat they too were now utilizing SegWit on Bitcoin transactions. Bitfinex wereclear of the advantages of the protocol upgrade, stating in their blogpost:
“We are delighted that through thisimplementation we can provide our customers with bitcoin withdrawal fees thatare up to 20 percent lower, as well as faster-than-ever transaction speeds.”
Coinbase were not so jubilant regardingthe upgrade, but they did offer a clear warning to users not to confuse Bitcoinand Bitcoin Cash deposit addresses. This is because following the change toSegWit the exchange is no longer able to retrieve funds.
“While SegWit should help reduce fees,once we begin rolling out this change, if you incorrectly send Bitcoin Cash (BCH) to aBitcoin (BTC) address, your funds will not be recoverable. Sending the incorrect digitalassets to a deposit address will result in permanent loss.
With Coinbase adopting SegWit it is expected there will be a significantincrease in the speed o the Bitcoin network, as the exchange represents a hugeproportion of transactions. SergejKotliar, CEO of mobile top-upservice Bitrefill, noted that the number of unconfirmed Bitcoin transactionsplummeted at the same time that Coinbase was experiencing an outage, whichsuggests that Coinbase transactions were a heavy load on the network. Theveracity of this claim has not been confirmed, but many are welcomingCoinbase’s adoption of SegWit regardless, hoping for both a faster and cheaperservice.
