misc

• random ID param for jsonrpc requests (bin/drk.rs)
• merge cashier branch
• update cashierd.rs to new config handling. note: password param in toml
• sqlcipher: better document install process or otherwise remove friction of using bundled version
• [X] remove default config from binaries and add to the readme
• [X] delete zkvm
• [X] SOL bridge poc
• Optional Cargo "features" for cashierd/darkfid, to {en,dis}able different chains

deposit

• drk: key generation
• drk: deposit cli option
• darkfid: check addresses are valid
• darkfid: send drk public key to cashierd.rs over tcp, triggered by drk.rs
• cashierd: receive BTC, mint dBTC (see tx.rs)
• cashierd: push tx to rocksdb (type: deposit, signed by cashier key)
• cashierd: watch address for deposit
• cashierd: resume watch after restart
• darkfid: poll gateway for new tx
• darkfid: for every new coin received, add to merkle tree
• darkfid: decode tx
• darkfid: perform state transition function
• darkfid: compute merklepath need to spend coin (see tx.rs)

withdraw

• drk: withdraw cli option
• darkfid: check address is valid
• darkfid: send cashout request to cashier with btc pub key
• cashierd: receive cashout request, reply with drk pub key
• darkfid: send dbtc to the cashier drk pub key
• cashierd: burn dbtc, send back btc (see tx.rs)

drk -> drk

• drk: transfer cli option
• darkfid: construct a new spend tx
• darkfid: check address is valid
• darkfid: build tx
• darkfid: verify tx
• darkfid: state transition function
• darkfid: send tx data to rocksdb

research

Open research questions.

light-clients

• Fast efficient batch DH technique. Currently all new transactions need to be scanned. There should be a means of efficiently batching this test for light clients initially syncing against a server.
• Anonymous fetch using an Oblivious-Transfer protocol. Light clients potentially leak info to servers based on the data they request, but with an OT protocol they do not reveal exactly what they are requesting.

cryptography

• FFT for polynomial multiplication
• finish bulletproofs impl
• halo2 lookup
• read groth permutation paper

blockchain

• basic sequencer architecture design
• basic DHT design
• consensus algorithm
• solve double verify problem (potentially need need a payment inside the contract to handle exceptions)
• research polygon design
• code up a simple demo

product

• first MPC services
• DAO
• auctions
• staking. Look up how TORN was distributed anonymously.
• swaps
• token issuance
• NFTs

dev

• make bitreich halo2 impl

halo2

• mint circuit poc
• burn circuit poc
• research port from jubjub to pasta (success)
• research port from blake2b to sinsemilla and/or poseidon
• solve poseidon gadget to hash >2 elements at a time
• integrate with actual codebase

org

• clean up shared repo and migrate to wiki
