📜 Usage

# generateProof(identity: Identity, group: Group | MerkleProof, externalNullifier: BigNumberish, signal: string, snarkArtifacts?: SnarkArtifacts): Promise\<SemaphoreFullProof>

import { Identity } from "@semaphore-protocol/identity"
import { Group } from "@semaphore-protocol/group"
import { generateProof } from "@semaphore-protocol/proof"
import { utils } from "ethers"

const identity = new Identity()
const group = new Group()
const externalNullifier = utils.formatBytes32String("Topic")
const signal = utils.formatBytes32String("Hello world")

group.addMembers([...identityCommitments, identity.generateCommitment()])

const fullProof = await generateProof(identity, group, externalNullifier, signal, {
    zkeyFilePath: "./semaphore.zkey",
    wasmFilePath: "./semaphore.wasm"
})

// You can also use the default zkey/wasm files (it only works from browsers!).
// const fullProof = await generateProof(identity, group, externalNullifier, signal)

# verifyProof(fullProof: FullProof, treeDepth: number): Promise\<boolean>

import { verifyProof } from "@semaphore-protocol/proof"

await verifyProof(fullProof, 20)
