Precisely, u should take into account that no money wants to pump this shit as person who created it speculates on the term "merkle tree" while not knowing anything about it. He just mentioned it but doesn't know what it is.
Here is the merkle trie database I wrote for aeternity.
https://github.com/BumblebeeBat/MerkleTrieThis is the library being used by the testnet that is live now.
It is written in erlang, and has lots of tests.
You can make and verify merkle proofs from the root of the database, and the root is recorded on each block.
I based it off of ethereum's patricia merkle trie.
