A permissioned Hyperledger Besu blockchain that sits alongside your core banking system as invisible security infrastructure. Zero crypto. Zero customer-facing change. Mathematical proof that every withdrawal was authorized.
In a recent and widely reported incident at a major West African bank, attackers breached the centralized database, inherited internal access controls, and silently executed thousands of coordinated withdrawals across branches nationwide in a single overnight window. No real-time anomaly detection fired. The audit trail was retrospective — the losses were booked hours before anyone noticed.
Direct losses in a single incident, attributed to coordinated cross-branch withdrawal fraud.
Executed simultaneously across multiple branches. None were blocked in real time.
Linked to an international cybercriminal network with cross-border operations.
KalyRails Bank deploys a private Proof-of-Authority blockchain built on Hyperledger Besu — the same technology powering SWIFT's new shared settlement ledger and Nigeria's eNaira CBDC. It sits alongside your existing core banking system (Temenos, Flexcube, Finacle, or equivalent) and enforces withdrawal rules in code.
Only authorized validator nodes can participate. Every transaction requires cryptographic signing — no anonymous access, no way to forge approvals from a database breach alone.
Proof-of-Authority consensus with ~2-second finality, low latency, and known validator identities. Purpose-built for regulated banking — not public crypto speculation.
On-chain withdrawal limits, velocity checks, multi-sig approval thresholds, and branch-level spending caps — enforced in code, impossible to bypass from the IT layer.
Every branch transaction is visible network-wide in real time. Anomaly patterns trigger automatic contract-level freezes — before the losses are booked, not after.
Request enters through your existing ATM, POS, or mobile banking channel. No customer-facing changes required — the customer uses the same card, same app, same PIN.
The integration layer creates a blockchain transaction carrying the amount, branch ID, and customer parameters — cryptographically signed by your operational key.
On-chain rules check: daily limit not exceeded? Velocity normal? Multi-sig approval needed? Branch cap OK? If any check fails, the transaction is rejected before it reaches consensus.
Validator nodes (HQ + branch regions) confirm the transaction. 2/3 validator agreement required. Finalized in approximately 2 seconds.
Funds release through core banking. A permanent, tamper-proof on-chain record is created — available to regulators, auditors, and compliance in real time.
An attacker with full database access still cannot forge cryptographic signatures. Smart contract velocity limits halt coordinated withdrawals before they compound. Real-time anomaly detection flags cross-branch patterns in seconds — not hours.
This is not a crypto project. There is no token, no coin, no digital currency, and no transaction fees. The blockchain operates as invisible security infrastructure — like upgrading from a paper ledger to a tamper-proof one.
Full GDPR and data sovereignty compliance. Customer PII never touches the blockchain.
Hyperledger Besu is not experimental technology. It is in production at central banks, global settlement networks, and tier-1 financial institutions on every continent.
SWIFT's new blockchain-based settlement ledger is built on Hyperledger Besu. 40+ institutions collaborated on the design — including JP Morgan, HSBC, Deutsche Bank, and Bank of America. Live MVP goes into production in 2026.
Africa's first CBDC. Retail payments have been running on Besu since October 2021 — proving production viability in West African regulatory and infrastructure contexts.
The wholesale CBDC project from Brazil's Central Bank. Built on Hyperledger Besu as the settlement backbone.
Project Garuda: 10+ commercial banks testing wholesale settlement on Besu. Led by Bank Indonesia.
Citi's tokenized deposit platform runs on private Ethereum / Besu infrastructure — moving real institutional balances between clients, 24/7.
Co-chair the Besu Financial Services Working Group — the governance body defining how Besu evolves for regulated financial institutions.
Nigeria's eNaira runs on Besu. We operate production Besu PoA networks today — not in a proof-of-concept, not in a lab, but serving real users in production.
Private transaction groups keep sensitive data confidential between specific parties while maintaining full audit transparency for regulators and supervisors.
Access to the largest smart-contract developer ecosystem on earth. All Solidity tooling, OpenZeppelin libraries, and Hardhat workflows work natively.
Built-in permissioning, KYC/AML integration points, and granular access controls designed to meet central bank requirements across the WAEMU region.
Sits alongside your existing Temenos, Flexcube, or Finacle deployment. No rip-and-replace. Customers see no change. Staff workflows unchanged.
We run an L1 blockchain, a cross-chain bridge, a DEX, an on-chain DAO, and a stablecoin protocol in production. This is not consultancy — this is operational experience.
Our smart contracts — withdrawal limits, velocity checks, multi-sig, freeze/pause, audit logging — are pre-built, battle-tested, and ready to deploy. We're not writing them from scratch for every engagement. That's why our timeline is a fraction of what traditional enterprise blockchain projects quote.
Infrastructure audit, network topology design, validator node placement, integration requirements mapping against your existing core banking stack. Pace depends primarily on your team's availability.
Besu PoA network goes live in 2–3 days (IBFT 2.0, permissioning, validators). Pre-built smart contracts are parameterized to your limits and policies. Remainder of the week covers API integration with core banking. Staging environment live by end of week.
Penetration testing, load testing across all branches, independent smart-contract audit, disaster recovery validation. No go-live without sign-off from your team and ours.
Pilot branch deployment, staff training, monitoring dashboards, gradual rollout to all branches. 24/7 support from day one of pilot.
We'd welcome the opportunity to discuss how a private Hyperledger Besu deployment can protect your customers and your reputation — built by a team that runs this infrastructure in production every day.
