Workshop on Poseidon
Workshop on Poseidon
Ethereum is one of the largest blockchains in the world and it relies on a variety of different cryptographic primitives and protocols that directly affect both its security and efficiency. Improving these tools is not only of academic interest, but also impacts the security of millions of users.
