Another project invested by a16z, Espresso, has just launched a contributor event, similar to an ambassador. In the future, these contributors may be incentivized. Those who are interested can study and research. Espresso related introduction: Espresso is a company focused on blockchain technology development, dedicated to building infrastructure that supports cross chain interoperability, with the aim of enabling different blockchains to work together like a single system@ The core product of EspressoSysEspresso Systems is Espresso Network, a global confirmation layer that provides fast and reliable transaction confirmation for the second layer (L2) blockchain, and ensures security through Byzantine fault-tolerant consensus mechanism. main features Cross chain interoperability: Espresso Network enhances interoperability between blockchains by providing real-time and reliable cross chain status confirmation. This allows any contract to call contracts on other chains, allowing users to seamlessly access applications on different chains, and liquidity to flow freely between chains. Quick Confirmation: Using the HotShot consensus protocol, Espresso can confirm transactions within seconds, far faster than the 15 minute finality of the Ethereum mainnet. This provides an efficient cross chain experience for bridging protocols, applications, and users. Decentralization and Modularity: Espresso Network supports decentralized sorting and low-cost data availability. It is compatible with other data availability layers such as EigenDA and Celestia, allowing chains to flexibly choose configurations. Ecosystem support: Espresso has integrated with multiple chains, including the three chains of the Cartesi ecosystem, the Rari Chain of the Arbitrarum ecosystem, Plume Network, and ApeChain. It also supports technology stacks such as Arbitrum Nitro, OP Stack, and Polygon CDK. Innovation and Research Espresso Systems not only develops production ready infrastructure, but also explores cutting-edge designs for cross chain interoperability through its research team. For example, they proposed the Circ protocol, which is a simple and efficient cross chain messaging protocol that supports synchronous interoperability, does not require modification of virtual machines, and has advantages such as fast proof and encrypted enforcement. Privacy and Openness Espresso Systems emphasizes openness and privacy. Its early product CAPE allowed asset creators to design custom privacy policies for assets such as stablecoins or NFTs, enhancing user control. The company adheres to the principle of open source development, publicly shares research results, and is committed to building a secure and decentralized blockchain ecosystem. Espresso Systems' mission is to prevent the fragmentation of the blockchain ecosystem, ensure that all chains work together, and maintain Ethereum's open, decentralized, and censorship resistant characteristics. They build systems that developers love and users trust based on rigorous engineering and research, while emphasizing transparent communication and community collaboration. Espresso Systems provides practical solutions for cross chain interoperability of blockchain through its Espresso Network and innovative protocols such as CIR. Whether it's providing fast confirmation, decentralized sorting, or driving cross chain experiences for NFTs and other applications, Espresso is paving the way for a more interconnected blockchain future.
