3 <p>A single keychain is a chain of script pubkeys derived from a single <a href="crate::miniscript::Descriptor"><code>Descriptor</code></a>. Keychains
4 are identified using the <code>K</code> generic. Script pubkeys are identified by the keychain that they
5 are derived from <code>K</code>, as well as the derivation index <code>u32</code>.</p>
6 <p>There is a strict 1-to-1 relationship between descriptors and keychains. Each keychain has one
7 and only one descriptor and each descriptor has one and only one keychain. The
8 <a href="struct.KeychainTxOutIndex.html#method.insert_descriptor" title="method bdk_chain::indexer::keychain_txout::KeychainTxOutIndex::insert_descriptor"><code>insert_descriptor</code></a> method will return an error if you try and violate this invariant. This
9 rule is a proxy for a stronger rule: no two descriptors should produce the same script pubkey.
10 Having two descriptors produce the same script pubkey should cause whichever keychain derives
11 the script pubkey first to be the effective owner of it but you should not rely on this
12 behaviour. ⚠ It is up you, the developer, not to violate this invariant.</p>
13 <h2 id="revealed-script-pubkeys"><a class="doc-anchor" href="#revealed-script-pubkeys">§</a>Revealed script pubkeys</h2>
14 <p>Tracking how script pubkeys are revealed is useful for collecting chain data. For example, if
15 the user has requested 5 script pubkeys (to receive money with), we only need to use those
16 script pubkeys to scan for chain data.</p>

20 <p>When an user first recovers a wallet (i.e. from a recovery phrase and/or descriptor), we will

29 <p>For script-pubkey-based chain sources (such as Electrum/Esplora), an initial scan is best done
30 by iterating though derived script pubkeys one by one and requesting transaction histories for
31 each script pubkey. We will stop after x-number of script pubkeys have empty histories. An
32 unbounded script pubkey iterator is useful to pass to such a chain source because it doesn’t
33 require holding a reference to the index.</p>
