IDEX 2.0, Built on Optimized
Optimized Optimistic Rollup (O2 Rollup) is a fresh open-source layer-2 approach aimed at enabling scalable applications on public blockchains.
IDEX 1.0 relies on a deposit contract and a single authorized submitter address. This setup supports escrow of funds and the coordination required for trade settlement, making instant off-chain execution possible. The main remaining limitations come from the network settling each trade sequentially. To grow past today’s blockchain throughput constraints, a more effective trade-settlement mechanism is needed.
IDEX created a new approach called O2 Rollup, designed to support unlimited off-chain scaling while keeping on-chain settlement costs fixed. To grasp how this works, it helps to review a few key ideas of the Ethereum network.
