Example of computing proofs for the zkdrops-contracts sample repo in the browser. The majority of the work is done by the zkdrops-lib which in turn uses the work of the iden3 team's Circom libraries.
Proof computation takes 20-60s in the browser depending on the machine.
This example front-end depends on the following locally served files:
mt_8192.txt– Sample merkle tree fromzkdrops/zkdrops-contracts/test/data/mt_8192.txtcircuit_final.zkey– ZKey used by proof generationcircuit.wasm– Circom wasm used to generate circuit proof by snarkjs
The zkdrops-lib includes imports for server-side only libraries. Because this usage is browser based, this repo ignores them during webpacking in next.config.js.
