ChainX is an inter-chain crypto-asset financial blockchain that will become a Polkadot parachain when the platform launches Q3 2019. ChainX is one of the first blockchains built on Substrate, a framework that makes it easy to build upgradable, efficient and innovative blockchains. Substrate chains can easily be integrated into the Polkadot network at genesis. ChainX has completed the development of BTC bridge and DEX, and we can expect BCH, LTC, ZEC bridge will be done soon because they all use similar POW consensus and UTXO transaction format. ChainX will launch at Q4 2018 and will continue to relay Ethereum and other POS chains.
