Succinct's first demo is a proof of concept bridge between Goerli (an Ethereum testnet) and Gnosis Chain that allows users to deposit "Succinct Tokens" (an ERC-20 we created) to a Goerli deposit contract and recieve minted Succinct tokens on Gnosis Chain. This demo showcases how Succinct's implementation of proof of

With gratitude to Yi Sun for writing the original spec, Jonathan Wang for circuit design help, and the Optimism & Arbitrum team for fruitful discussions. We present circom-batch-ECDSA (link to repo), a proof-of-concept implementation building on top of circom-ECDSA (previous work done by others in the 0xPARC community) with inspiration from

Over the past few years, there has been a variety of different blockchain ecosystems offering decentralized settlement layers for various applications. These blockchains lie on different points of the tradeoff curve of decentralization, security, throughput, and cost. Decentralized applications have varied requirements and developers can choose which platform is best
