 The next few hexadecimal digits (+0385840206+) are used to encode an extra _nonce_ (see <<extra_nonce>>), or random value, used to find a suitable Proof-of-Work solution.

-The final part of the coinbase data (+2f503253482f+) is the ASCII-encoded string +/P2SH/+, which indicates that the mining node that mined this block supports the pay-to-script-hash (P2SH) improvement defined in BIP-16. The introduction of the P2SH capability required signaling by miners to endorse either BIP-16 or BIP-17. Those endorsing the BIP-16 implementation were to include +/P2SH/+ in their coinbase data. Those endorsing the BIP-17 implementation of P2SH were to include the string +p2sh/CHV+ in their coinbase data. The BIP-16 was elected as the winner, and many miners continued including the string +/P2SH/+ in their coinbase to indicate support for this feature.

 <<satoshi_words>> uses the libbitcoin library introduced in <<alt_libraries>> to extract the coinbase data from the genesis block, displaying Satoshi's message. Note that the libbitcoin library contains a static copy of the genesis block, so the example code can retrieve the genesis block directly from the library.
