Polkadot smart contract

Polkadot’s first mainnet chain candidate, Phase 1, launched on May 27, 2020 . It marked the initial step in a multi-stage rollout process detailed in the project’s mainnet launch roadmap.

The Polkadot network includes a main blockchain called the “relay chain” and many user-created parallel chains (or “parachains”) . It also has a connecting layer, or “bridge,” that allows value and data to be transferred between most blockchains — and can even be used to connect to non-blockchain databases.

After years of development and promises of interoperability, the Polkadot network moved toward its first Ethereum virtual machine (EVM) compatible smart contract protocol with the launch of Moonbeam (GLMR).
