Guest:
Jordi Baylina is a telecommunications engineer, blockchain developer and co-founder of the White Hat Group. Jordi is the founder of Giveth, DAppNode and founder and Technical Lead of iden3 and Hermez Network.

Hermez is a Layer 2 solution that scales token transfers on top of Ethereum and can handle up to 2,000 transactions per second. Designed for high-frequency tokens such as ETH, wBTC and DAI, Hermez is a zero-knowledge rollup, leveraging zkSNARKS for validity proofs and with on-chain data availability. Powered by the HEZ token, its technology includes a circuit compiler language, Circom, and a novel consensus algorithm, Proof-of-Donation, that gives 40% of each transaction fee back to Ethereum Layer 1 as a donation, thereby supporting Ethereum development.

Target audience:
Anyone interested in zkRollups and blockchain scaling solutions!
