bsc-p2p

Lightweight BSC block listener. Joins the devp2p network as an eth/68 peer and prints new blocks.

go build -o bsc-p2p .
./bsc-p2p          # just blocks
./bsc-p2p -v       # + peer events, discovery

Flags

Flag	Default	Description
-rpc	https://bsc-dataseed.bnbchain.org	RPC for initial head fetch
-port	0 (auto)	TCP/UDP listen port
-bootnodes	(official BSC)	Comma-separated enode URLs
-v	off	Verbose logging

How it works

1. Fetches current head from RPC (for Status handshake)
2. Computes EIP-2124 ForkID from hardcoded BSC fork schedule
3. Starts go-ethereum p2p.Server with discv4 discovery
4. Handshakes eth/68 Status + BSC UpgradeStatus with each peer
5. Prints NewBlock messages, drops stale blocks

Discovered peers are cached to ~/.cache/bsc-p2p/peers for fast reconnect.
