What’s parallelization got to do with Polygon PoS?

PoS was the first scaling solution to make parallelization possible via Block STM on the Delhi hard fork upgrade.

Parallelization means simultaneous, rather than sequential transactions 🤲

On PoS this enables faster ⏩ transactions and less gas price spikes during high demand times.

It happens by embedding transaction dependency metadata in block headers, which reduces pending transactions in the mempool, and reduces execution time by 50%.

Towards the end of 2023 (when Ethereum Inscriptions were having their moment), PoS processed 16.5M txs in one day, and handled more than 160M inscriptions, at ~240 transactions/second.
