Quantum-resilient by design
Exploring hybrid post-quantum cryptography and upgradeable security controls.
Quantum-resilient settlement technology
New rails for trusted international settlement.
Pactway is a technology project built on Hyperledger Fabric, exploring quantum-resilient, auditable settlement between verified institutions and integrations with regulated digital money and existing payment rails.

Built on Hyperledger Fabric. Designed for integration, not tied to a single token or payment network.
Designed for institutional trust.
A technology foundation for settlement networks where security, governance and interoperability matter.
Permissioned and auditable
Verified participation, shared records and configurable transaction policies.
Integration-first
Designed to connect regulated issuers, banking systems and local settlement rails.
The foundations, simply explained.
A shared settlement record, strong controls and security built to evolve.
Protecting tomorrow's transactions.
Today's signatures and some methods for establishing encrypted connections may be vulnerable to future quantum computers. Post-quantum cryptography uses newer mathematical methods designed to resist those attacks.
Two complementary protections: quantum-resistant digital signatures authenticate identities and transaction approvals, while quantum-resistant key establishment helps protect encrypted connections carrying sensitive data.
Our Fabric proof of concept focuses on hybrid signatures combining classical and post-quantum techniques. Network-wide protection, secure key rotation and upgradeable algorithms are part of the longer-term architecture, not a completed security certification.
A trusted network, not another bank.
At its core is Hyperledger Fabric, a permissioned blockchain where known participants share transaction evidence, and governance rules determine who can approve settlement actions.
1Verified participants — organisations, digital identities and access policies.
2Shared settlement layer — transaction state, approval rules and auditable history.
3Financial integrations — potential connections to licensed issuers, reserves, FX providers and local payout rails.
Regulated money issuance and redemption would remain the responsibility of appropriately authorised partners.
Potential applications.
One core platform, adaptable to different regulated settlement models.
Cross-border B2B settlement
Regulated stablecoin infrastructure
Tokenized bank-money networks
Institutional treasury and liquidity flows
