Earlier, the team commissioned two external firms to analyse 37 components of zkEVM. The timelines for completion are unknown.<\/p>\n<p>The key improvements in the final testnet were:<\/p>\n<ul class=\"wp-block-list\">\n<li>The introduction of recursion, enabling a single <a href=\"https:\/\/u1f987.com\/en\/news\/what-is-a-zero-knowledge-proof\">zero-knowledge proof<\/a> (ZK) to verify a batch of others&#8217; proofs;<\/li>\n<li>Support for parallel operation of multiple \u201cprovers\u201d to improve scalability. Proofs are generated faster and at lower cost for users (currently $0.04 per transaction);<\/li>\n<li>Implementation of transaction aggregation to batch them for processing.<\/li>\n<\/ul>\n<p>The team recommended users migrate to the new testnet version, since the old one will be deprecated on 5 January 2023.<\/p>\n<p>As of Dec. 20, the network had 2,264 smart contracts deployed, 10,508 wallets registered, 21,966 transactions executed, and 14,930 ZK proofs created.<\/p>\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh4.googleusercontent.com\/KrocXvHqxSoZ7Ov3JfIgXjaLZkBt_x6AT_iFLVWNgrtVjz_wm5WDqGjhvuIbyfojFSz2ax519ekAUs_I0JqxRAKVFSlwAy6lktRuV12fK0tz12kvXwSwYB4BLJe-H4TLxFq1ocgChIxnefpisHVRW0HhuG9GsCie2YrrOJfUDjBtpkBxOY4GHysXk32MXA\" alt=\"Polygon updates the zkEVM scaling testnet\"\/><figcaption>Source: Polygon.<\/figcaption><\/figure>\n<p>Earlier, in November 2021, the project team <a href=\"https:\/\/u1f987.com\/en\/news\/polygon-unveils-zk-rollups-based-scaling-solution-for-ethereum\">announced a new Layer 2 solution for Ethereum<\/a> based on ZK-Rollups and released its central component\u2014the virtual machine <span data-descr=\"Ethereum Virtual Machine, the Ethereum virtual machine\" class=\"old_tooltip\">EVM<\/span>, which uses the zk-STARKs protocol.<\/p>\n<p>In July, the developers unveiled <a href=\"https:\/\/u1f987.com\/en\/news\/polygon-team-unveils-new-zkevm-scaling-solution\">the zkEVM scaling technology<\/a>.<\/p>\n<p>Read ForkLog&#8217;s Bitcoin news on our <a href=\"https:\/\/telegram.me\/forklog\" target=\"_blank\" rel=\"nofollow noopener\">Telegram<\/a> \u2014 cryptocurrency news, rates and analysis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Polygon project unveiled the final pre-mainnet version of its test network for scaling Ethereum called zkEVM.<\/p>\n","protected":false},"author":1,"featured_media":71810,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"select":"1","news_style_id":"1","cryptorium_level":"","_short_excerpt_text":"","creation_source":"","_metatest_mainpost_news_update":false,"footnotes":""},"categories":[3],"tags":[1179,1264,277,1134],"class_list":["post-71809","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-and-analysis","tag-layer-2-solutions","tag-polygon-matic","tag-scaling","tag-technical-updates"],"aioseo_notices":[],"amp_enabled":true,"views":"24","promo_type":"1","layout_type":"1","short_excerpt":"","is_update":"","_links":{"self":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts\/71809","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/comments?post=71809"}],"version-history":[{"count":1,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts\/71809\/revisions"}],"predecessor-version":[{"id":71811,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts\/71809\/revisions\/71811"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/media\/71810"}],"wp:attachment":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/media?parent=71809"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/categories?post=71809"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/tags?post=71809"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
