EthCC 2: Greg Markou
summary
Built multiple client side chains by forking Parity and Geth, injecting a Postgres indexer and a custom Merkle-tree opcode, and running a hybrid POW/POA where authority signers can flip sealing modes; asset moves use a chainbridge in Go with authorized signers (centralized trust). Lessons: need modular, hot-swappable consensus and block components; Polkadot’s parachain uses relay chain security lets heterogeneous chains inherit security and message-passing; proof concept: collapse every ~50 blocks into super Merkle headers posted on the relay.
