- Project: Subcoin, a Rust Bitcoin Full Node implementation.
- Grant: Received from Web3 Foundation to showcase
polkadot-sdk
. - Objective: Implement decentralized Bitcoin fast sync.
- Challenges: Substrate's limitations caused Out-of-Memory (OOM) errors during state sync.
- Progress: Identified root cause and developed a plan with
polkadot-sdk
maintainers. - Proposal: Submitted a follow-up grant, recommended for treasury funding.
- Issues: OOM on large state import and lack of persistent state sync.
- Goal: Resolve OOM issue and implement persistent state sync for Substrate.
