Zero-Blockchain & the on-chain stack
From Zero-Blockchain (ZC-1) - our DAG + BFT Layer-1 for regulated digital assets - to audited smart contracts, dApps and Web3 frontends. Quantum-resistant, sub-2s finality, 100,000+ TPS - and a contract library already deployed across 18 industries.

What “production-ready” actually means
Every figure below comes from a live network or a benchmark we'll happily reproduce on a screen-share. No vapour, no roadmap-marketing.

The on-chain stack, end to end
Six layers, each one independently auditable. We'll happily walk a regulator, security team or board of directors through every box.

Byzantine fault tolerance
Instant finality, even when a third of the network goes dark
Zero-Blockchain runs a 2f+1 BFT consensus over a permissioned validator set. The chain finalises every block in a single round — no probabilistic confirmations, no waiting six blocks for a settlement to be “safe”.

Zero-Blockchain
Our purpose-built L1 for regulated assets
Zero-Blockchain is the flagship Layer-1 we build on, targeting regulated digital assets (e-money, tokenised deposits, securities). Design pillars: deterministic finality, native compliance hooks (KYC binding, allow-list assets), EVM-compatible execution layer, and pluggable consensus (Tendermint-style BFT). Includes a reference wallet, indexer, and token-issuance toolkit. The Zero-Bank consumer ecosystem runs on top of it.

How we work together
Three ways to engage
Pick the shape that fits your stage. We'll tell you honestly if a different one would serve you better.
Discovery sprint
1 - 2 weeksPin down the problem, the constraints and the smallest thing worth building.
- Stakeholder interviews & goal mapping
- Architecture spike + risk register
- Costed roadmap and clickable prototype
Fixed-scope build
4 - 16 weeksA defined deliverable, shipped to production with full handover.
- Milestone billing, weekly demos
- CI/CD, tests, docs, runbooks
- Two-week post-launch hyper-care
Embedded squad
Rolling, 3+ monthsSenior engineers integrate with your team and ship alongside you.
- Daily standups in your tooling
- Code reviews, mentoring, pairing
- Flexible scope, monthly retainer
Our process
From first call to second release
Five stops. No mystery. You always know what we're doing this week and what evidence we'll bring next week.
1
Discover
Goals, users, constraints, risks. We come back with a costed plan and a sharp scope.
2
Architect
Tech choices, data model, security & compliance. Decisions documented in ADRs.
3
Build
Iterative sprints, weekly demos, every change behind tests and code review.
4
Launch
Staged rollout, telemetry, runbooks, on-call cover. We babysit the first two weeks.
5
Iterate
Measure, learn, ship. Roadmap reviewed monthly against the metrics that matter.

“They walked in with a live DAG-BFT testbench doing six figures of TPS, a quantum-resistant signature scheme baked into the protocol, and a security-token contract suite that passed two independent audits with zero highs. Most of our shortlist was still talking about roadmaps.”

Common questions
Things people ask
Can't see yours? Drop us a line - we'll usually reply within the working day.
Ask a different questionReal chain. ZC-1 is a DAG-based Layer-1 with two-phase BFT checkpointing (prevote / precommit), VRF committee selection, and CRYSTALS-Dilithium post-quantum signatures. Validators publish Blocklets in parallel and a single-slot BFT vote extracts a totally-ordered cut every 1.2 seconds. EVM-equivalent execution sits on top so existing Solidity contracts deploy unchanged.
