Why LiqFi

  • promise-icon-1

    Risk Free

    Private key security makes subscription payments, automated payments, and on chain reputations extremely fraught with risk.

  • promise-icon-2

    Confidential

    We aim to enable a new type of automated transactions with delegated signing features using group and proxy re-signature technology.

  • promise-icon-3

    Scalable

    Promise use of proxy re-signatures for signing authority delegation will enable new blockchain applications and wider adoption.

  • promise-icon-4

    Automated

    DApps can now have their own private keys so that automated and repeated payments can be delivered without the need to store private keys online.

LiqFi Protocol

The liqFi Protocol solves the private key security problem by using a new encryption scheme that allows delegation of signing by proxy re-signature.

Liqfi also delivers delegation and authorization control so that transactions for re-signatures and payments will have authorization respected at the consensus level.

Features

  • feature-icon-1

    Delegated Re-Signatures

    Proxy res-signature cryptography for automated payments and subscriptions processing.

  • feature-icon-2

    Proofs

    Zero knowledge proof and commitments deliver transactions that are required for global business.

  • feature-icon-3

    High Throughput

    Pruned transactions and high throughput makes scaling to millions of transactions easy via the Promise sidechains.

  • feature-icon-4

    Automated Transactions

    Automated signing transactions possible via cryptographic primitives means faster processing and less overhead than running VM for these transaction types.

  • feature-icon-5

    Virtual Machine

    Virtual machine for delivering complex automated payment contracts means that developers can write very complex automated payment logic.

  • feature-icon-6

    Decentralized Finance

    Decentralized finance for those who don’t want to worry about private key safety and public key addresses from a blockchain that promises to just work

Use Cases

delegated-payments

Delegated Payments

Managing private keys and handling payment flow via proxy is hard. Delegating payment execution to services that can handle payments in a trustless environment makes it easier to allow peers to pay on behalf of peers.

automated_subscription_payments

Automated Subscription Payments

Proxy re-signatures allow for repeated payments to be delegated to a machine that may sign a scheduled transaction for a scheduled payment, without the need to reveal the original private key of the subscriber.

loans_credit

Loans and Business Credit

Credit is a measure of willingness and ability to repay. Proxy re-signatures lower the costs to re-paying promissory note and credit commitments by allowing more than one party to contribute to a repayment while building credit for the borrowing party.

gifts_charitable

Anonymous Gifts and Charitable Giving

Gifts and charitable giving benefit from proxy re-signatures when benefactors wish to maintain anonymity and to make payments either as the charity or an organization making payments on behalf of a charity.

authorized_payments

Authorized Payments

Proxy Re-signatures allow for payment flow control so that only authorized members may prox re-sign a transaction. This is important for compliance and repayment control where payments are only acceptable if delivered by a particular public key.

pay_my_bills

Sample DApp LiqFi

Promise Solutin: LiqFi is a proxy re-signature application that signs your bill payment for you for the exact amount and with a proxy re-signature of the payment transaction that is valid for the payment of your invoice.
