Every rendered "T-Chain" / "ThresholdVM" / "teleportvm" reference across the paper corpus is rewritten to the correct canonical chain by concern: threshold signing / MPC / bridge custody / key recovery -> M-Chain (MVM); FHE / encrypted compute / threshold decryption -> F-Chain (FVM); teleport / cross-chain messaging -> B-Chain (bridgevm); consensus Pulsar stays Q-Chain. Section lux-trust-kernel/03-t-chain-threshold-governance.tex renamed -> 03-f-chain-encrypted-policy.tex (with \input + xref fixes). Braided "T-Chain" sections split by concern (M vs F). Only lp-020's chain-separation rationale and the shared lux/chains/thresholdvm library path retain the name, to record the removal. All changed papers rebuilt (pdflatex, rc=0, no undefined refs). ยง09 of lux-dao-governance-framework reframed: fabricated "production deployment" metrics ($50M/$240k/$12M, survey %s, "as of Oct 2024") relabeled as illustrative design configurations with no invented replacements; reality noted (DAO treasury is a 1/1 Safe); conclusion echo + one "first production" overclaim softened. This commit also captures concurrent corpus workstreams on the same tree. Co-authored-by: Hanzo Dev <[email protected]>

\section{Cross-Chain Collateral via M-Chain}

|
|
|
|
|
\subsection{Bitcoin as Collateral}
|
|
|
|
Lux Credit's integration with M-Chain enables Bitcoin to be used as collateral without wrapping tokens:
|
|
|
|
\begin{lstlisting}[language=Solidity, basicstyle=\small\ttfamily]
|
|
interface IBitcoinCollateral {
|
|
struct BTCVault {
|
|
bytes32 btcTxHash; // Bitcoin deposit transaction
|
|
bytes btcAddress; // Threshold custody address
|
|
uint256 amount; // BTC amount (satoshis)
|
|
bytes32 luxLoanId; // Associated Lux Credit loan
|
|
uint256 unlockHeight; // Bitcoin block for redemption
|
|
}
|
|
|
|
// Deposit BTC and receive Lux Credit loan
|
|
function depositBTCForLoan(
|
|
bytes calldata btcProof, // SPV proof of deposit
|
|
uint256 luxAmount // Desired loan amount
|
|
) external returns (bytes32 loanId);
|
|
|
|
// MPC threshold signature for BTC redemption
|
|
function redeemBTC(
|
|
bytes32 loanId,
|
|
bytes calldata btcDestAddress
|
|
) external returns (bytes32 redemptionTxHash);
|
|
|
|
// Verify Bitcoin transaction via M-Chain
|
|
function verifyBTCDeposit(
|
|
bytes calldata spvProof,
|
|
bytes32 btcTxHash
|
|
) external view returns (bool);
|
|
}
|
|
\end{lstlisting}
|
|
|
|
\subsection{MPC Threshold Custody}
|
|
|
|
Bitcoin collateral is secured using M-Chain's threshold signatures (from LP-13):
|
|
|
|
\textbf{Key Features:}
|
|
\begin{itemize}
|
|
\item 15-of-21 threshold for BTC custody addresses
|
|
\item CGG21 ECDSA protocol (80ms signing)
|
|
\item Pulsar quantum-safe extension (7ms combining)
|
|
\item \$3.2B volume processed with zero security incidents
|
|
\end{itemize}
|
|
|
|
