Zero-Knowledge Time-Locking (ZKTL)

Overview

Zero-knowledge time-locking (ZKTL) is a cryptographic mechanism that enables time-delayed access to encrypted data while preserving complete privacy. It leverages zero-knowledge proofs (ZKPs) and time-lock encryption to allow verifiable computations over time without revealing sensitive information.

ZKTL ensures that data, transactions, or validator actions remain securely locked for a specified duration. This prevents unauthorized access, front-running, and premature decryption while maintaining blockchain transparency and quantum security.

Key Features of ZKTL

• Quantum-Resistant Zero-Knowledge Proofs (ZKPs) – Protects time-locked data from quantum attacks.
• Privacy-Preserving Time-Lock Encryption – Enables trustless delays without revealing intermediate computations.
• AI-Assisted Adaptive Locking – Adjusts lock durations dynamically based on network security conditions.
• Validator Staking Time-Lock Protection – Prevents premature stake withdrawal by malicious actors.
• Quantum-Secure Transaction Commitment – Ensures timed release of blockchain transactions and smart contract actions.

How ZKTL Works

1. Time-Lock Initialization

   • A zero-knowledge proof (ZKP) commitment is generated for the hidden data or transaction.
   • The data is encrypted and time-locked using a computationally hard function (e.g., lattice-based encryption).
   • The verifier can verify that the data exists without learning its contents.

2. Zero-Knowledge Proof Verification

   • A trusted or decentralized network verifies the validity of the commitment using ZKPs.
   • No party learns the original data until the time-lock expires.

3. Time-Based Decryption & Unlocking

   • Once the predefined time-lock period expires, the zero-knowledge proof allows the data to be decrypted.
   • The private key or unlocking mechanism is revealed only after a sufficient amount of computation has been performed.

ZKTL Cryptographic Model

The ZKTL function follows a time-lock encryption and proof-based unlocking mechanism, ensuring delayed data release without compromising privacy:

$$\text{Commitment} = H(g^x \mod p)$$

Where:

• $$H$$ = Quantum-Resistant Hash Function (SPHINCS+, XMSS, Lattice-Based Hashing)
• $$g^x \mod p$$ = Time-Locked Exponential Puzzle
• $$x$$ = Secret Key Encapsulated in Zero-Knowledge Proof
• $$p$$ = Large Prime Modulus for Cryptographic Security

Unlocking Condition (Zero-Knowledge Proof Completion)

To unlock the time-locked value, the participant must prove in zero-knowledge that the required computational steps have been executed:

$$\text{ZK-Proof: } \exists x \text{ such that } H(g^x \mod p) = \text{Commitment}$$

This ensures that the data or transaction can be decrypted only after the necessary computational delay has elapsed.

ZKTL in Action: Use Case Scenario

Scenario: Time-Locked Governance Proposals

1. A governance proposal is submitted but should remain locked until voting begins.
2. The proposal details are encrypted using ZKTL, ensuring that no validator or delegatee can access them before the voting window.
3. Once the predefined block height is reached, the zero-knowledge proof unlocks the proposal for transparent voting.
4. actions remain verifiable, but no party can tamper with the contents before the unlock period.
