Getting Started

This tutorial will help you install Unirep and run examples

Download Unirep Social

Clone Unirep Social source code from github
git clone https://github.com/vivianjeng/Unirep-Social.git

Install packages

Install packages used in Unirep Social
yarn install

Build the Circom circuits

Build circom circuits and generate their constraints and verification keys and proving keys files in the build/ directory. Also export smart contract verifiers to be deployed with Unirep and Unirep Social smart contract.
yarn build

Test

Test all cli commands
yarn test-cli
Integration test
yarn test

Example cli commands workflow

1. Run a testing net

We use hardhat here as a blockchain developing environment.
NOTE: a list of default accounts will be printed, choose one of them to be user's account and one to be attester's. User's and attester's private key will be referred to as deployerPrivateKey and attesterPrivateKey respectively.
For example:
Accounts
========
Account #0: 0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266 (10000 ETH)
Private Key: 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
...
​
npx hardhat node

2. Deploy Unirep smart contract and its verifiers

If we choose the first account, we use 0xac097...ff80 as our deployerPrivateKeyparameter Open another terminal and run:
npx ts-node cli/index.ts deploy -d 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
NOTE: -dis deployer's private key Then Unirep and Unirep Social contract's address will be printed. For example,
Unirep: 0x0165878A594ca255338adfa4d48449f69242Eb8F
Unirep Social: 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853
  • Then we use the Unirep Social contract's address to interact with.
Unirep Social contract will sign up as the an attester with attester ID1. When users spend reputation to publish a post or leave a comment, Unirep Social contract will perform as an attester to give users negative reputation.

3. Generate user's identity and identity commitment

npx ts-node cli/index.ts genUnirepIdentity
NOTE: base64url encoded identity and identity commitment will be printed, For example,
Unirep.identity.WyJlOGQ2NGU5OThhM2VmNjAxZThjZTNkNDQwOWQyZjc3MjEwOGJkMGI1NTgwODAzYjY2MDk0YTllZWExMzYxZjA2IiwiODZiYjk5ZGQ4MzA2ZGVkZDgxYTE4MzBiNmVjYmRlZjk5ZmVjYTU3M2RiNjIxMjk5NGMyMmJlMWEwMWZmMTEiLCIzMGE3M2MxMjE4ODQwNjE0MWQwYmI4NWRjZDY5ZjdhMjEzMWM1NWRkNDQzYWNmMGVhZTEwNjI2NzBjNDhmYSJd278
Unirep.identityCommitment.MTI0ZWQ1YTc4NjYzMWVhODViY2YzZDI4NWFhOTA5MzFjMjUwOTEzMzljYzAzODU3YTVlMzY5ZWYxZmI2NTAzNw

4. User signs up

The user signs up with his identity commitment instead of his real identity.
npx ts-node cli/index.ts userSignup \
-x 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853 \
-c Unirep.identityCommitment.MTI0ZWQ1YTc4NjYzMWVhODViY2YzZDI4NWFhOTA5MzFjMjUwOTEzMzljYzAzODU3YTVlMzY5ZWYxZmI2NTAzNw \
-d 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
NOTE: -x is the Unirep Social contract address and -c is user's identity commitment

5. Attester signs up

npx ts-node cli/index.ts attesterSignup \
-x 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853 \
-d 0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d
NOTE: -d is attester's private key, this private key is to be used only by this attester hereafter
NOTE: Though user signs up requires a private key, private key is used to interact with smart contract but not link identity commitment and the account.
However, attesterSignupbind the account with attester id. Whenever the user wants to attest others, the user has to use the account he has registered for as an attester.
Therefore, users can sign up their identity commitments and their attester ids with different accounts to enjoy more privacy protection.

6. User generates epoch key and epoch key proof

The user can generate an epoch key with his identity and nonce.
npx ts-node cli/index.ts genEpochKeyAndProof \
-x 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853 \

-n 0
NOTE: -id is user's identity and -n is epoch key nonce which should be less than the system parameter maxEpochKeyNonce
NOTE: epoch key and base64url encoded epoch key proof will be printed and they should be handed to attester to be verified, for example:
Epoch key of epoch 1 and nonce 0: 69

NOTE: -epk is user's epoch key and -pf is the epoch key proof

8. User publish a post with an epoch key and proof

When a user wants to publish a post, he has to generate his reputation proof to prove that he has enough reputation to make a post. The proof also validate the epoch key.
npx ts-node cli/index.ts publishPost \

9. Verify reputation proof of certain transaction

Users can use the reputation proof with the transaction hash to obtain snark circuit and its public inputs. Then user can call the on-chain verifier to verify the proof.
npx ts-node cli/index.ts verifyReputationProof \

10. Attester upvotes to epoch key

To upvote an epoch key, we need another user with different identity. So we generate an identity and sign up the second user in the same way.
npx ts-node cli/index.ts genUnirepIdentity
npx ts-node cli/index.ts userSignup \
-x 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853\

13. User generate reputation proof from certain attester

After user state transition, the user can generate a proof to prove that he has reputation from certain attester.
npx ts-node cli/index.ts genReputationProofFromAttester \
-x 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853 \

-mn 1 \
-gp 0
NOTE: -a is attester's id -mp is the minimum positive reputation score, i.e, user wants to prove that the attester gave the user a positive reputation score that's larger than the minimum positive reputation score -mn is the maximum negative reputation score, i.e, user wants to prove that the attester gave the user a negative reputation score that's less than the maximum negative reputation score -md is the minimum difference between positive and negative reputation scores -gp is the pre-image of the graffiti for the reputation
NOTE: gp in this case, 0 being the hash pre-image of 176ff05d9c7c4528b04553217098a71cd076d52623dab894a7f7ee34116ca170
