The protocol upgrade introduced a number of benefits which can enable more advanced second-layer protocols. It also offers a block size limit increase for wallets that utilize the new feature, meaning users can enjoy lower fees and faster confirmation times.<\/p>\n<p>One week in, Segregated Witness has been implemented in several wallets, though overall adoption is off to a bit of a slow start. While many wallets and services <a href=\"https:\/\/bitcoincore.org\/en\/segwit_adoption\/\" target=\"_blank\" rel=\"noopener\">indicated<\/a> prior to the activation that they would be ready for the upgrade, many are taking a bit of a conservative approach when it comes to main-net release, while others have since faced unrelated difficulties that demanded their attention.<\/p>\n<p>So far, hardware wallets are among the first to have jumped on the new opportunity. Both <a href=\"https:\/\/trezor.io\/\" target=\"_blank\" rel=\"noopener\">Trezor<\/a> and <a href=\"https:\/\/www.ledger.com\/\" target=\"_blank\" rel=\"noopener\">Ledger<\/a> have fully implemented and enabled Segregated Witness. This is not very surprising: Hardware wallets stand to <a href=\"https:\/\/bitcoinmagazine.com\/articles\/how-segregated-witness-is-about-to-fix-hardware-wallets-1478110057\">benefit<\/a> from SegWit more than most wallets, as it helps to significantly speedup the signing process.<\/p>\n<p>\u201cBut we mostly implemented Segregated Witness to help the network first,\u201d Ledger CTO Nicolas Bacca told <em>Bitcoin Magazine<\/em>. \u201cThe more Segregated Witness transactions are used, the more space there is for everybody. In a way we\u2019re also doing our part to disarm the 2x part of the SegWit2x hard fork.\u201d<\/p>\n<p>Another hardware wallet provider,<a href=\"https:\/\/shiftcrypto.ch\/\" target=\"_blank\" rel=\"noopener\"> Digital Bitbox<\/a>, also implemented Segregated Witness in its firmware, cofounder and Bitcoin Core contributor Jonas Schnelli told <em>Bitcoin Magazine<\/em>, but it still requires a compatible desktop app to utilize the feature. This is a work in progress.<\/p>\n<p>Full node wallets like Bitcoin Core are also in the process of implementing Segregated Witness. But Bitcoin Core developers decided to not include the feature straight away in order to avoid edge-case attacks that become harder to execute as time passes. Bitcoin Core will instead release a new version of the software, 0.15.1; this could take another month or two before it\u2019s available.<\/p>\n<p>As for regular wallets, it seems that <a href=\"https:\/\/blockstream.com\/\" target=\"_blank\" rel=\"noopener\">Blockstream<\/a>\u2019s <a href=\"https:\/\/greenaddress.it\/nl\/\" target=\"_blank\" rel=\"noopener\">GreenAddress<\/a> could well be the first to offer the feature.<\/p>\n<p>\u201cIt&#8217;s days away,\u201d GreenAddress developer Lawrence Nahum told <em>Bitcoin Magazine<\/em>. \u201cWe were ready a while back; however, during testing we found that fees were a bit higher in one of our wallets. That\u2019s because some software libraries available now weren\u2019t available when we implemented SegWit. At this point it\u2019s mostly a matter of more testing.\u201d<\/p>\n<p>Most other wallets are also in various stages of implementing the feature, but for various reasons haven\u2019t gotten to the point of release quite yet. In some cases, like <a href=\"https:\/\/www.bitgo.com\/\" target=\"_blank\" rel=\"noopener\">BitGo<\/a> and <a href=\"https:\/\/btc.com\/\" target=\"_blank\" rel=\"noopener\">BTC.com<\/a>, this had to do with the prioritization of integrating Bitcoin Cash into their service; the new cryptocurrency launched unexpectedly only a couple of weeks ago. Similarly,<a href=\"https:\/\/wallet.mycelium.com\/\" target=\"_blank\" rel=\"noopener\"> Mycelium<\/a> told <em>Bitcoin Magazine<\/em> it has been implementing new features which diverted some time and attention away from SegWit.<\/p>\n<p>Other popular wallets, including <a href=\"https:\/\/play.google.com\/store\/apps\/details?id=de.schildbach.wallet&amp;hl=nl\" target=\"_blank\" rel=\"noopener\">Bitcoin Wallet<\/a> (also known as Schildbach\u2019s Bitcoin Wallet), <a href=\"https:\/\/brd.com\/\" target=\"_blank\" rel=\"noopener\">Breadwallet<\/a>, <a href=\"https:\/\/electrum.org\/\" target=\"_blank\" rel=\"noopener\">Electrum<\/a>, <a href=\"https:\/\/ciphrex.com\/\" target=\"_blank\" rel=\"noopener\">mSIGNA<\/a>, as well as webwallet <a href=\"https:\/\/xapo.com\/\" target=\"_blank\" rel=\"noopener\">Xapo<\/a> confirmed that they are implementing SegWit, and all told <em>Bitcoin Magazine<\/em> that they expect this should be available soon \u2014 though none gave a specific timeframe for it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After a years-long development process and even more debate and political struggle, Segregated Witness finally activated on the Bitcoin network last week.
