For nerds in the audience who were wondering - what’s Polygon PoS’ architecture?

It’s divided into three layers:

1️⃣ Ethereum layer: a set of contracts on the Ethereum mainnet

2️⃣ Heimdall layer: a set of proof-of-stake Heimdall nodes running in parallel to the Ethereum mainnet, monitoring the set of staking contracts deployed on the Ethereum mainnet, and committing the Polygon PoS network checkpoints to the Ethereum mainnet, based on Tendermint.

3️⃣ Bor layer: a set of block-producing Bor nodes shuffled by Heimdall nodes, based on Go Ethereum
