Research Objectives

This research investigates the practical implementation of NEAR Protocol's chain signatures technology, focusing on Multi-Party Computation for secure cross-chain asset management and transaction execution.

  • Security analysis of threshold signature schemes in cross-chain contexts
  • Performance optimization for sub-second transaction finality
  • Economic incentive design for validator networks

Key Innovations

Threshold Cryptography

Advanced implementation of t-of-n threshold signature schemes enabling secure distributed key management without single points of failure.

Cross-Chain Verification

Novel approaches to verifying transaction validity across heterogeneous blockchain networks with different consensus mechanisms.

Economic Security

Comprehensive analysis of economic incentives and attack vectors in decentralized cross-chain signature schemes.

Technical Implementation

Multi-Party Computation Protocol

# NEAR Chain Signatures MPC Implementation
use near_crypto::{PublicKey, Signature};
use mpc_recovery::{SignRequest, MPCSignature};
use threshold_crypto::{SecretKeyShare, PublicKeySet};
struct ChainSignatureRequest {
transaction_hash: Vec<u8>,
chain_id: u64,
derivation_path: String,
}
impl MPCProtocol {
pub fn sign_transaction(
&self,
request: &ChainSignatureRequest
) -> Result<Signature, MPCError> {
// Threshold signature generation
let shares = self.collect_signature_shares(request)?;
self.combine_shares(shares)
}
}

Cross-Chain Integration

# Cross-Chain Transaction Flow
interface CrossChainBridge {
function submitTransaction(
bytes32 transactionHash,
uint256 targetChainId,
bytes memory signature
) external;
}
contract NEARChainSignatures {
mapping(bytes32 => bool) public processedTxs;
mapping(uint256 => bytes32) public validators;
function verifyAndExecute(
bytes32 txHash,
bytes memory mpcSignature
) external {
require(verifyMPCSignature(txHash, mpcSignature));
executeTransaction(txHash);
}
}
