summary

Polkadex prototypes an order book using a client-side pallet crate that runs alongside Grandpa/BABE/Beefy and an alternative using an offchain worker. On-chain matching earlier took 6–12 seconds per inclusion with ~1,500 tx/block, so a 200-validator gossip design using a gossip engine nearly stalls the chain for ~30 minutes during a spike. Client-side pallets need 67% validator binary upgrades and expose raw keystores; offchain workers use HTTP, allow faster runtime upgrades, and rely on 67% on-chain attestation signatures to accept summaries.
