TechOptimism targets 200 ms subblocks while standard data feeds lose key fields
Optimism is targeting 200-millisecond subblocks on OP Mainnet. After the migration, state_root, block_hash and withdrawals_root will be zeroed and withdrawals will be empty in streamed payloads, creating a compatibility risk for applications consuming WebSocket data directly and RPC providers forwarding raw fields. They must treat those values as unavailable rather than feeding them into state, balance or proof inputs.
