Hermez zkRollup -
Decentralized zkRollup on Ethereum.Main task has been to implement the Hermez node, used to launch the mainnet of the zkRollup network (1.0):
hermeznetwork/hermez-node
My focus has been mainly in the TxSelector, TxProcessor (managing the rollup state tree) and BatchBuilder (generating the data structure compatible with the zkSNARK circuits to do the proof generation).
