As a zkApp engineer, you must learn about themerkle treesection at Mina Doc. Well, o1js library provides a memory-based classic MerkleTree implementation and MerkleMap implementation which is for sparse merkle trees. But pleaseNOTICE: the both currently are in memory, meaning the data is lost...
log('standard tree initial root: ', standardTreeInstance.getRoot(includeUncommitted).toString()); // append the first leaf of type: Field, the newly inserted leaf is kept in an array before being flushed into db. await standardTreeInstance.appendLeaves([ Field( '...
Note that things that need super-fast torrent startup do not need to concern themselves with the bulky hash list in the torrent root dictionary. Those things can be handled by extending BEP9 to send those hashes piecemeal after obtaining the more lightweight info dictionary. Also note I'm ...
FIGS. 3A, 3B, 3C, and 3D illustrate a novel Merkle B-Tree 300 of order O=3, meaning that there are three branches from each node. As shown in FIG. 3A, for level n=0, the blockchain HASH digest in root B-Block 301B is the hash of the root object 301, and each succeeding dat...

After importing a proof, if you receive additional proofs against the same database (meaning it has the same root), you can merge these proofs in too:$ quadb mergeProof --hex < my-proof2 If the computed root of the new proof differs from the root of your current head, an error ...

But please NOTICE: the both currently are in memory, meaning the data is lost if the process is terminated. So we need to design a persistent storage to keep the data. And this library provides a set of useful merkle trees implementations with capability of persistence for you! Within the ...
Then, the final leaves have indexes between 2𝑙2l and 2𝑙+1−12l+1−1 (here, 𝑙=0l=0, meaning a degenerate tree with only the root node). The verification starts from the bottom of the tree (on level l). For verification purposes, we need to calculate hashes on the path...
