🎉 Exciting news! Our research team just demonstrated verifiable inference on Bitcoin, leveraging blockchain technology and cryptography to bring more trustworthiness to AI.
Imagine the approach can prove that:
✅A generative AI model is trained on datasets known to have no bias
✅AI developers can prove that they did not tamper with the training datasets to train an AI model for malicious intentions
✅A piece of artwork comes with a proof showing that it is generated by an AI model on a given prompt
✅As a paid user, you can be sure that you are getting answers from ChatGPT4, not the free versions. This is how we can contribute to verifiable AI.

nChain
Enterprise blockchain infrastructure, IP development, and verifiable AI tools tailored for Bitcoin SV
2.7/ 5
Our score
Weak
What is nChain?
nChain is an enterprise blockchain software and intellectual property development firm focused primarily on the Bitcoin SV network. Founded in 2015, the firm produces digital currency software, verification protocols, and custom ledger integrations for institutional deployments.
Corporate background and ownership
Headquartered in London, United Kingdom, with operations in Switzerland through nChain AG, the company operates as a subsidiary of the Ayre Group. Former leadership includes CEO David Washburn and Jimmy Nguyen, who served as CEO before becoming chair of the strategic advisory board. Former chief scientist Craig Wright was historically associated with the firm before a 2024 UK High Court ruling found he had fabricated documents regarding claims to be Satoshi Nakamoto.
Technology and platform mechanics
The company builds blockchain protocols, software libraries, and data infrastructure centered on the Bitcoin SV network. In August 2024, the engineering team demonstrated zero-knowledge proof verification on the Bitcoin SV mainnet to support private smart contracts. The firm also provides enterprise digital currency systems intended for central banks and financial institutions handling cross-border payments. In September 2024, nChain introduced verifiable inference workflows for artificial intelligence, recording cryptographic checks on-chain to verify model integrity and dataset authenticity.
Track record and enterprise deployments
nChain holds a broad portfolio of registered blockchain patents and has integrated its software with commercial partners such as payments platform Centbee and mobile platform Planetary. The company has also faced governance disputes. Former chief executive Christen Ager-Hanssen was dismissed for gross misconduct in September 2023 following an attempted takeover, later receiving a 10-month UK prison sentence for contempt of court. In June 2026, the London Central Employment Tribunal dismissed retaliation claims brought by former directors Andrew Moody and David Brookes, ruling the allegations lacked substance.
Risks and technical limitations
Deploying nChain solutions carries ecosystem concentration risk. The firm designs its core developer tooling and transaction verification frameworks around Bitcoin SV rather than multichain architectures like Ethereum or Solana. Technical documentation, clear software uptime service-level agreements, and public pricing tiers are not made broadly accessible online, requiring direct enterprise sales engagements.

Pros and cons
Pros
- Operates high-throughput infrastructure tailored for the Bitcoin SV mainnet
- Verified zero-knowledge proof execution natively on the Bitcoin SV network in 2024
- Maintains an established patent portfolio covering enterprise cryptographic workflows
- Active in enterprise payment partnerships including Centbee and Planetary
Cons
- Primary infrastructure focuses on Bitcoin SV rather than EVM or Solana ecosystems
- Publishes no public pricing tiers, node developer consoles, or self-serve APIs
- No publicly stated uptime service-level agreements or live status dashboards
- Leadership and corporate governance faced past legal disputes in UK courts
Our review
2.7/5
Weak
nChain provides research-heavy enterprise infrastructure and patents centered on Bitcoin SV, but its single-network ecosystem and lack of published developer pricing limit broad market adoption.
Founded in 2015, nChain is an enterprise infrastructure and blockchain intellectual property firm headquartered in London and majority-owned by the Ayre Group. The firm focuses primarily on the Bitcoin SV (BSV) network, offering software solutions that cover verifiable artificial intelligence inferences, zero-knowledge proofs on BSV, central bank digital currency (CBDC) frameworks, and cross-border settlement architecture.
Its primary strengths lie in its deep institutional research and proprietary patent portfolio. In 2024, the team demonstrated on-chain zero-knowledge verification on the Bitcoin SV mainnet alongside verifiable model inference methods for artificial intelligence datasets. nChain also actively targets public-sector and enterprise deployments, presenting technical frameworks directly to central banks and financial institutions for sovereign digital currencies. Partnerships include Centbee for payments, Planetary for metaverse applications, and Universal Plastic.
However, nChain presents notable trade-offs for mainstream Web3 developers. Its core infrastructure is tailored heavily to Bitcoin SV rather than multichain or EVM environments. Pricing tiers, free call limits, node service level agreements, and uptime guarantees are not published publicly on its portal, requiring direct outreach to sales. The company has also experienced internal disruption, including legal battles following an attempted takeover by a former chief executive in 2023. In June 2026, the London Central Employment Tribunal dismissed related whistleblowing claims brought against nChain UK by former directors, ruling the allegations were without substance.
Teams developing specifically on Bitcoin SV or enterprise consortia exploring sovereign digital currency architectures may find nChain's intellectual property useful. Developers seeking off-the-shelf multichain RPCs, indexed APIs, or public pay-as-you-go infrastructure should evaluate alternative multi-network providers.
