The performance of blockchain technology has been greatly improved since we initially assessed this area in the Radar. However, there's still no single blockchain that could achieve "internet-level" throughput. As various blockchain platforms develop, we're seeing new data and value silos. That's why cross-chain tech has always been a key topic in the blockchain community: the future of blockchain may be a network of independent parallel blockchains. This is also the vision of Cosmos. Cosmos releases Tendermint and CosmosSDK to let developers customize independent blockchains. These parallel blockchains could exchange value through the Inter-Blockchain Communication (IBC) protocol and Peg-Zones. Our teams have had great experiences with CosmosSDK, and the IBC protocol is maturing. This architecture could solve blockchain interoperability and scalability issues.
