vmtree-sdk

Library for constructing computational integrity proofs to advance the state of verifiable merkle trees. Now using poseidon!

Lifted files

I took the below files into this repository to avoid using the older version of ffjavascript. I modified the mimcsponge file to be similar to the poseidon implementation.

mimcsponge.js

Lifted directly from a deprecated version of circomlib, modified to use ethers instead of web3-utils.

poseidon.js

Lifted directly from a deprecated version of circomlib

poseidon_constants_opt.json

Same as above: from circomlib

merkleTree.js

I added a wrapper class for tornado's fixed merkle tree library, to be consistent with the hash functions in this project.
