Hash chains built with BLAKE2b
License: MIT License
Hi! Is there a particular reason why you don't use a merkle tree for summary hashes? Generally they allow quick append of a summary hash rather than having to run through the whole chain to build up the new summary state.
I'm here after looking at chronicle... which is an interesting project.
Hello,
i'm having trouble with verification. i hope you will help.
what i want to do is keep retrospective data changes and verify them when necessary. but i have not succeeded yet.
i can describe it with a sample code as follows.
<?php
$real = [
'title' => 'Test Title',
'body' => 'Test Body',
];
$histories = [
[
'title' => 'Test Title 1',
'body' => 'Test Body',
],
[
'title' => 'Test Title 1',
'body' => 'Test Body 1',
],
[
'title' => 'Test Title',
'body' => 'Test Body',
],
];
$chainA = new \ParagonIE\Blakechain\Blakechain();
collect( $histories )->each( function($item) use ($chainA) {
$chainA->appendData( json_encode( $item ) );
);
$chainB = new \ParagonIE\Blakechain\Blakechain(
new \ParagonIE\Blakechain\Node( json_encode($real), $chainA->getLastNode()->getPrevHash() )
);
dd( $chainA->getLastNode()->getHash() == $chainB->getLastHash() );
i tried something like, but i was not successful. i know what i'm doing is wrong. But i did not know what to do at the point of verification. i'm blocked because there is not enough document.
