When should we use a permissioned chain instead of a public one?

When all participants must be identified, data must stay confidential between named parties, or regulation forbids a public ledger. If you need open participation and public verifiability instead, a public or Layer 2 chain is the better fit. We help you decide in the strategy phase.

Which platforms do you deploy?

Primarily Hyperledger Fabric and GoQuorum, with Besu in IBFT mode for EVM-compatible private networks. The choice depends on whether you need EVM tooling, the privacy model, and the consensus and performance profile your consortium requires.

Can a permissioned chain run on our own infrastructure?

Yes. We deploy on-premises, in your cloud tenancy, or hybrid across consortium members. Each organisation typically runs its own nodes and identity authority, which is the point: no single party controls the network.

Permissioned enterprise chains

Private, consortium-grade ledgers where only known parties transact and data stays confidential.

We stand up permissioned networks on Hyperledger Fabric, Quorum (GoQuorum) and similar platforms for consortia that need a shared ledger without a public chain. We handle membership services, channels and private data collections, ordering and consensus (Raft, IBFT), and chaincode development. This suits banks, supply-chain consortia and government use cases where every participant must be known and confidentiality is non-negotiable.

How we engage

A clear path from problem to outcome

Discovery and protocol selection

We map your use case, trust model and stakeholders, then choose the right chain and consensus: public EVM (Ethereum, Polygon, Base, Arbitrum), a permissioned ledger (Hyperledger Fabric, Quorum), or a Layer 2. We confirm whether a blockchain is actually warranted before any code is written.

Architecture and threat modelling

We design the on-chain and off-chain split, data and key-management model, gas and fee strategy, and upgrade path. Every contract is threat-modelled against known attack classes (reentrancy, access control, oracle manipulation) so security is built in, not bolted on.

Build, test and audit

We develop in Solidity, Vyper or chaincode with full unit, fork and invariant test coverage using Foundry or Hardhat. Contracts go through static analysis (Slither), fuzzing and an internal security review before any deployment to a public or production network.

Deploy, verify and operate

We deploy with reproducible scripts, verify source on the explorer, and hand over runbooks, monitoring and indexing (subgraphs, event listeners). Optional managed operations cover key rotation, upgrades and incident response after go-live.
