Hello,
We have built a proof-of-concept of Flashbake in a private chain.
We transact by sending an operation to a flashbake relay. The relay acts as a regular tezos-node RPC endpoint, but intercepts the injection operation and forwards it to the next flashbake-capable baker, bypassing the mempool.
Flashbake-capable endpoint URIs are recoded in on-chain contract storage.
We then run 2 concurrent transactions, one with a higher fee than the other, and observe that the one with the higher fee is included first.
The experiment is described in more details here, along with intructions to replicate it.
Our focus is now to deploy flashbake on testnet and mainnet.
