Intro from my blog:

This interactive demo explores Bitcoin SV block headers using real data from a Teranode-mined block. I’m running the BSV Block Headers Service locally – a Go application that connects to the BSV P2P network to collect and serve blockchain header information.

The demo shows the actual API response from querying block #909,036, then breaks down each field in the 80-byte block header. You can click on each field to learn what it represents, distinguishing between the standard Bitcoin protocol fields (version, prevBlockHash, merkleRoot, creationTimestamp, difficultyTarget, nonce) and the service-calculated fields (hash and work) that are computed for convenience. This illustrates both the elegance of Bitcoin’s design and how SPV (Simplified Payment Verification) enables lightweight verification without downloading entire blocks.
