Paper 2022/1470 Casting out Primes: Bignum Arithmetic for Zero-Knowledge Proofs , Polygon Zero , Polygon Hermez Abstract We describe a nondeterministic method for bignum arithmetic. It is inspired by the "casting out nines" technique, where some identity is checked modulo 9, providing a probabilistic result. More generally, we might check that some identity holds under a set of moduli, i.e. $f(\vec{x}) = 0 \mod m_i$ for each $m_i \in M$.

Optimism is designed to scale Ethereum. The scaling solution processes transactions outside the Ethereum mainchain and then bundles them back onto it. As a result, the project can significantly reduce ETH transaction costs. For example, a token swap via Uniswap on Optimism currently costs just $0.529. On the main Ethereum network, users have to pay $25.39 for the same transaction. And now Optimism is launching what could be the biggest token airdrop the crypto space has seen so far.

2 hours ago • 3 min read By Polygon Hermez We are delighted to announce that we’re publishing the initial package of documentation about the architecture of the zkEVM project, which we’re calling Polygon Hermez 2.0. In this blog post, you’ll find a summary of the initial public documentation set, which will grow as we create it. You can also read the documentation here, if you want to delve deeper into it.
