v2.0.0-beta-4

• Contract deployment: Testnet deployment 🧩
• Circuits have been audited ✨
• Fix epoch tree, multi-attester bug 🐛
• Replacement field has been changed 👓
  • 205 bits data (upper bits)
  • 48 bits index (lower bits)
• Use verifier helpers instead of verifiers deployed with Unirep.sol ⛑️
• Remove prover from Synchronizer, prover should be provided in UserState
• Learn more about v2.0.0-beta-4 from documentation 🙌🏻

v2.0.0-beta-3

V2 beta 3 is a bugfix release. It includes the following changes

#402 Add an attestationCount variable that replaces timestamp in replacement fields
#403 Fix a compilation error in webpack by bumping a dependency version

v2.0.0-beta-2

V2 beta 2 introduces the following major changes

#339 Add support for signup using a custom state tree leaf/initial data
#345 Customize sync poll rate/block count
#351 Add semaphore proof circuit for unirep epoch keys
#367 Multi attester support for synchronizer
#372 Deterministic address deployments
#382 Seal epochs non-interactively (remove ordered merkle tree)
#386 Add history tree, don't reveal from_epoch in UST
#400 Combine replacement fields and timestamp fields into single field

Problems noted in the internal audit are addressed in this release as well. See #369 for more info.

v2.0.0-beta-1

V2 beta 1 introduces the following changes

#282 Build ordered tree instead of sparse merkle tree (epoch tree), so the epoch key doesn't require to mod TREE_ARITY**TREE_DEPTH. Uses sealedEpoch function instead of processing hash chains.
#288 Adds @unirep/test package
#295 Supports circom 2.1.3
#298 Adds AttesterSignedUp event
#301 Uses identitySecret instead of identityNullifier
#303 Allows many attesters to be synced in one Synchronizer, which is used in @unirep/explore
#322 Changes the pos_rep, neg_rep, graffiti, timestamp fields to a array of data fields

Pre-built proving keys and a testnet deployment are maintained here.

Breaking API changes:

• genEpochKey and genUserStateTransitionNullifier takes identitySecret instead of identityNullifier. Identity secret can be computed by

  import { ZkIdentity } from '@unirep/utils'
  const id = new ZkIdentity()
  const identitySecret = id.secretHash

• Hash chain related functions (buildHashchain, processHashchain, attesterHashchainTotalCount, attesterHashchainProcessedCount, attesterHashchain,...) are all replaced by sealEpoch, attesterEpochSealed
• The UserState object takes a Synchronizer object during construction.

  const synchronizer = new Synchronizer({
  prover: defaultProver, // a circuit prover
  unirepAddress: '0xaabbccaabbccaabbccaabbccaabbccaabbccaaaa',
  provider, // an ethers.js provider
  })
  const state = new UserState(synchronizer, identity)

• the stop() function in synchronizer is now non-async
• getRep(), getProvableRep(), getRepByEpochKey() has been renamed to getData(). getProvableData(), getDataByEpochKey()

2.0.0-alpha-3

V2 alpha 3 introduces a number of changes designed to improve performance of ZK proofs and reduce calldata needed for proof submission onchain.

#210 adds variable arity support for the epoch tree. This reduces the number of constraints by between 10-50% depending on the proof.
#211 fixes a bug with the reputation proof minimum reputation logic.
#216 changes the proofs to accept multiple distinct values in a single public signal.
#232 adds a lite epoch key proof that doesn't include a membership check.
#239 adds a multi-epoch key proof.

Pre-built proving keys and a testnet deployment are maintained here.

Breaking API changes:

• All proof classes have been moved from the @unirep/contracts package to the @unirep/circuits package.
• getRepByAttester has been renamed to getRep, and a new function getProvableRep has been added.
  • These functions accept only an epoch now.
• The getVKey function in the Prover interface is now async.

1.0.3

Adds epoch argument to getAttestations function, solving a potential collision.
