<p>Represents the wallet’s birthday which can be thought of as a checkpoint at the earliest moment in history where
|
||
transactions related to this wallet could exist. Ideally, this would correspond to the latest block height at the
|
||
time the wallet key was created. Worst case, the height of Sapling activation could be used (280000).</p>
|
||
|
||
<p>Knowing a wallet’s birthday can significantly reduce the amount of data that it needs to download because none of
|
||
the data before that height needs to be scanned for transactions. However, we do need the Sapling tree data in
|
||
order to construct valid transactions from that point forward. This birthday contains that tree data, allowing us
|
||
to avoid downloading all the compact blocks required in order to generate it.</p>
|
||
|
||
<p>New wallets can ignore any blocks created before their birthday.</p>
