REChain PoC Phase 0 Implementation Steps

Detailed Steps to Complete All In Progress Items

1. Implement etcd snapshot tool (Go/Python script for snapshot, chunking, upload)

• Update src/snapshot/snapshot.go: Add etcd client integration for snapshot creation
• Integrate MinIO upload for chunks
• Implement proper Merkle tree computation

2. Set up MinIO for CAS storage

• Ensure MinIO integration in snapshot.go works with docker-compose

3. Compute Merkle tree for chunks

• Enhance computeMerkleRoot function in snapshot.go for full Merkle tree

4. Mock GCL (single-node Tendermint or simple REST mock)

• Enhance src/gcl/mock_gcl.go to run as REST server
• Add to docker-compose.yml

5. Publish snapshot tx to GCL

• Integrate GCL publishing in snapshot creation

6. Basic restore with Merkle verification

• Add RestoreSnapshot function in snapshot.go

7. Simple CRDT catalog (in-memory OR-Set)

• Create src/catalog/catalog.go with OR-Set implementation

8. REST API server for snapshot ops

• Update src/api/server.go to integrate snapshot, catalog, GCL

9. CLI tool (rechainctl) for commands

• Update cmd/rechainctl/main.go to call actual functions

10. Unit tests for Merkle, chunking

• Enhance tests/snapshot_test.go
• Add tests for catalog and Merkle

11. Integration test: snapshot -> upload -> restore

• Create tests/integration_test.go

12. Docker Compose for local setup (etcd, MinIO, GCL mock)

• Update config/docker-compose.yml with GCL mock service
