Synthetic Diamond-Backed Stablecoin Power

d-coin offers real asset value with certified diamond reserves and transparent proof-of-reserve.

About Synthetic Diamond Coin D-Coin

D-Coin, launched by Xillion Foundation (Singapore), is a diamond-backed stablecoin transparently collateralized by certified diamond reserves. Through its on-chain Proof-of-Reserve mechanism, D-Coin replaces fiat trust with tangible asset value — building a new standard for non-dollar stability.

The D-Coin reserve employs blockchain transparency, distributed custody, and multi-signature auditing. All diamonds are third-party certified and serial-numbered, with reserves traceable on-chain and via audit reports. The structure follows MAS AML/KYC compliance standards.

  • Background and SWIFT Limitations

  • Established in 1973, SWIFT connects over 11,000 financial institutions worldwide as the primary interbank communication standard. However, SWIFT operates as a centralized messaging network requiring correspondent banks for settlement, leading to slow transactions (1–5 business days), high costs, and vulnerability to geopolitical sanctions.

D-Coin: A Decentralized Blockchain-based Replacement for SWIFT

Abstract

D-Coin introduces a blockchain-based decentralized cross-border payment infrastructure designed to replace the SWIFT messaging system. By integrating distributed ledger, decentralized identity, and programmable settlement layers, D-Coin eliminates intermediary dependence, enhances transaction transparency, and ensures regulatory compliance through cryptographic proofs.

Comparison of SWIFT and D-Coin Architecture

D-Coin consists of three core layers: Ledger Layer, Identity Layer, and Settlement Layer. The ledger layer ensures message = settlement, the identity layer provides zero-knowledge-based compliance, and the settlement layer executes programmable logic through smart contracts.

Security and Regulatory Compliance

D-Coin integrates AML and KYC compliance through a hybrid on-chain/off-chain verification model. Regulatory nodes can audit encrypted metadata without accessing personal data. Zero-knowledge proofs (ZKP) enable selective disclosure while satisfying FATF and GDPR compliance simultaneously.

Conclusion and Patent Applications

D-Coin represents the foundational evolution from centralized financial messaging to decentralized programmable settlement. Its integration of identity, ledger, and compliance layers enables global financial communication without reliance on legacy intermediaries.
