Parity Technologies' Polkadot has launched a testnet, Rococo, of the protocol's first parachain specification, according to a blog Thursday.

Parachains underlie Parity Tech's vision of a "Protocol for protocols."

Rococo allows developers to "Register" a Substrate-based blockchain as part of Polkadot's grander parachain network.

Substrate is a blockchain building kit for other networks to interoperate as a Polkadot parachain.

Rococo is the first test of inter-blockchain communication through its Relay Chain logic.

Rococo launched as a Proof-of-Authority network under the governance of Parity Technologies.

The testnet will begin with three parachains, the firm said.
