ICON

<p>In March, the team has activated BTP blocks on the Berlin testnet. BTP contracts, that are currently one-way trustless, have been deployed on ICON Berlin testnet, BSC testnet, and ETH Sepolia. In this article, we share tasks completed and development milestones for April.</p><h2 id="header-0">BTP Architecture/ Product</h2><p>It has been a busy month of March, with the team making great progress. BTP blocks have been activated on the Berlin testnet! BTP contracts, that are currently one-way trustless, have been deployed on ICON Berlin testnet, BSC testnet, and ETH Sepolia.</p><p>The BTP contracts enable trustless outbound messaging from the ICON blockchain. Inbound messages are currently still making use of trusted relay verification (similar to ICON bridge).</p><p>Now, it’s time to continue testing, identifying improvements, fixing bugs, and improving the relay and BMV components. After one-way bridging, our team will work towards full trustless bridging with BTP on testnet.</p><p>This is also the perfect time for other teams to explore how they can adopt BTP’s xCall to enable new functionality on their applications. They can help identify any missing tools or documentation that would assist in onboarding teams to adopt the technology.</p><p>More information on the testnet incentivisation plans will follow shortly.</p><h3 id="last-month">Last Month</h3><ul><li>Continue <a href="https://www.notion.so/eb52eafdbc0e496596fbd27d5c5ecdc9" rel="noopener noreferrer nofollow">Unit testing ETH 2.0</a> BMV implementation - Done</li><li>Continue developing <a href="https://www.notion.so/3ee0ee535e28408eaf8698bfc01e1500" rel="noopener noreferrer nofollow">relay implementation for ETH 2.0</a> - with the team building a custom API they can now continue this work. - Done</li><li><a href="https://www.notion.so/f88cddd9133346908a6a3ae2e10ec7d0" rel="noopener noreferrer nofollow">Unit Test relay</a> implementation for ETH 2.0 - Done</li><li>Deploy integration on <a href="https://www.notion.so/Deploy-ETH-2-0-integration-on-local-ICON-ETH-2-0-instance-a5557ff37ded457ea7a76659aa6790ac" rel="noopener noreferrer nofollow">local ICON &amp; ETH 2.0 instance</a> - Done</li><li>Test integration on <a href="https://www.notion.so/3de4168cb55f442fba8d9689a4aee1bd" rel="noopener noreferrer nofollow">local ICON &amp; ETH 2.0 instances</a> - Done</li><li><a href="https://www.notion.so/d5aa750d86334cffb7666d69c17a5ba5" rel="noopener noreferrer nofollow">Deploy and test Local</a> ICON instance with ETH Sepolia testnet - Done</li><li><a href="https://www.notion.so/38bd5777c2484ad0b48161dcc7741536" rel="noopener noreferrer nofollow">Deploy integration to new ICON testnet and connect to eth Sepolia testnet</a> - Done</li><li><a href="https://www.notion.so/5c26696670894328a0ddcc48a75331ee" rel="noopener noreferrer nofollow">Unit Test relay implementation for BSC</a> - Done</li><li>Continue <a href="https://www.notion.so/1b4241a97347447aaf626031ea46f07c" rel="noopener noreferrer nofollow">integration testing</a> of the implementation of BSC BMV - Done</li><li>Commence <a href="https://www.notion.so/5c26696670894328a0ddcc48a75331ee" rel="noopener noreferrer nofollow">testing relay implementation for BSC</a> - Done</li><li>Deploy new <a href="https://www.notion.so/b8f5a255991d49feac7138a7148c1097" rel="noopener noreferrer nofollow">ICON testnet and connect to BSC testnet</a> - Done</li><li><a href="https://www.notion.so/ab2e979b62fd43deb031ba3125f99e6a" rel="noopener noreferrer nofollow">Commence end-to-end testing</a> on new ICON testnet connected to BSC testnet -Done</li><li><a href="https://www.notion.so/aa95c574bcb046d18f02811667d89f3e" rel="noopener noreferrer nofollow">Network proposal</a> on Berlin testnet to activate BTP Blocks - Done</li></ul><h3 id="next-month">Next Month</h3><p>BSC &amp; ETH</p><ul><li>Start <a href="https://www.notion.so/dd55ff14b0dc46e28feecc9bebbb187b" rel="noopener noreferrer nofollow">BTP blocks testing</a> on Berlin testnet</li><li>Deploy <a href="https://www.notion.so/1a5121eb34ab4c96a88a3ac6736df413" rel="noopener noreferrer nofollow">BSC integration to ICON (berlin) &amp; BSC testnet</a></li><li>Start <a href="https://www.notion.so/10fc5892f3e8497493a02ad2ff32e909" rel="noopener noreferrer nofollow">End to end testing</a> on ICON (berlin) &amp; BSC testnet</li><li><a href="https://www.notion.so/662a73d06c544979aa3d5feb6800d947" rel="noopener noreferrer nofollow">Deploy integration to ICON Berlin &amp; ETH Sepolia testnet</a></li><li><a href="https://www.notion.so/fe184f9a2f244a70af320b211bf1cbaf" rel="noopener noreferrer nofollow">End to end testing for ICON Berlin testnet &amp; eth Sepolia testnet</a></li><li>Ongoing BSC and Eth relay testing and debugging</li><li>Ongoing BSC and ETH BMV testing and debugging</li></ul><p><a href="https://www.notion.so/BTP-2-0-337aa608385449aca6656cbc065a4419" rel="noopener noreferrer nofollow">BTP 2.0 code refactoring</a></p><ul><li>Splitting the source code into several reposJava - Done<br />Solidity - Done<br />Relayer-common - Done<br /></li></ul><h3 id="challenges">Challenges</h3><p>It is worth noting again that as we get to the stage of deploying BTP to its respective testnets, we expect to face minor issues due to the general nature of testnets.
