Provide source-code concepts from the Solana whitepaper in Golang to understand proof-of-history and the mechanics behind Solana further.

Used as an exercise to understand Proof of History further by writing a simple implementation as described in the whitepaper.

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

make bench

Simulate benchmarks to generate proof-of-history (POH) using a single core, and verify the output on multiple cores.

• Calculate hashrate for POH generation (single core)
• 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
