August 7, 2020 Polkadot launches Rococo test environment for interoperable parachains.

Polkadot has launched a testnet for the protocol’s first parachain specification, the project announced Thursday. Rococo is the first test of PolkaDot’s Relay Chain logic for inter-blockchain communication. On this testnet, users will be able to register blockchains based on the Substrate building kit. The network intends to have three operation parachains using Proof-of-Authority consensus and will be governed by Polkadot.
