Used as an exercise to understand Proof of History further by writing a simple implementation as described in the whitepaper. ## Usage ``` make build ``` Build from source ``` ./bin/poh-golang ``` Run a proof-of-history to generate the hashrate on a single core, and validate the results on all available CPU cores ``` CPU Cores 8 Generate Hashrate 1482625 p/sec (1-core) Verify Hashrate 4701530 p/sec (8-cores) Verify Hashrate 587691 p/core ``` ## Benchmarks ``` make bench ``` Simulate benchmarks to generate proof-of-history (POH) using a single core, and verify the output on multiple cores. ## Roadmap - [X] Calculate hashrate for POH generation (single core) - [X] Calculate hashrate for POH validation (multiple cores) - [ ] Implement Solana hash table indexes for user addresses and packet payloads described in the whitepaper. - [ ] Add GPU support via Cuda implementation of SHA256 - [ ] Synchronize multiple POH validators on the local network - [ ] Implement event signatures - [ ] Add basic Proof of Stake implementation as per the Solana whitepaper - [ ] Implement vote support for PoS implementation - [ ] Implement election for PoS and simulate PoH generator failure - [ ] Add PoH election support and secondary validator promotion - [ ] Implement Streaming proof of Replication using basic CBC encryption and XOR inputs
