ChainX XBTC 2.0 Testnet Phase One: Completed

2 min readApr 25, 2021


The XBTC 2.0 upgrade is a landmark event for ChainX where it upgrades its BTC cross-chain. With the first completed test of XBTC 2.0, ChainX will continue to upgrade its BTC cross-chain function within one year and introduce the latest technological advances in the industry, including decentralized vault technology and threshold signature technology (MPC). This upgrade is also the cornerstone for ChainX to build a BTC-based cross-chain DEFI center. The upgraded ChainX BTC cross-chain will have many advantages. Its better security, convenience, and timeliness provide a solid foundation for building mirrored assets and DeFi applications.

The three-week XBTC 2.0 event ended successfully. This event attracted nearly 1,000 participants, being 411 overseas users and 455 domestic users.

Two fixed tasks were set up in this test event, of which 253 people completed the task of minting and redeeming XBTC, and 275 people completed the task of BTC vault. In addition, the fans who participated in the test also opened 41 issues on Github, 9 of which have already been addressed and closed. The other 32 issues are being processed. According to the rules of the event, we will randomly select users who completed the tasks and reward them with KSX. As the rules stated, those who successfully completed the tasks are eligible to share 500 KSX together.

List of winners for task one: cldvn, Josh, zvsgjc, kobe, luxebeng

List of winners for task two: mahasri307, LISUHUI, Vu, canon221, ZSPKOLIVER

The list of winners for task three: EOSBlock, Primo Gennaio, Kocan212, qhm1227, ionika

The test lasted for a long time, but the majority of fans who participated in the test have always been actively involved in the test. In the first week, nearly 500,000 test coins were released every day. Here, on behalf of ChainX, I would like to extend my heartfelt thanks to the fans. We appreciate your continued support and promotion of ChainX.
