Blockchain
Pairing the best blockchain developers with the most progressive businesses.
Distributed ledger technology is transforming how organisations record, share, and verify information. From financial services and supply chain to healthcare and public administration, blockchain enables a new generation of business processes built on immutability, transparency, and decentralised trust.
Arthur J Goldman brings together deep blockchain technical expertise and board-level strategic advisory to help organisations navigate this rapidly evolving landscape. Whether you are assessing blockchain feasibility, building your first decentralised application, or securing an existing protocol, our consultants deliver the clarity and capability you need.
Request a QuoteComprehensive blockchain advisory and delivery from strategy through implementation, audit, and ongoing governance.
We guide organisations through blockchain adoption, from feasibility assessment to full implementation strategy. Our consultants evaluate whether distributed ledger technology is appropriate for your use case and design the optimal architecture, whether public, private, or consortium blockchain. We help leadership teams build the business case, secure stakeholder buy-in, and establish a realistic implementation roadmap aligned with organisational objectives.
Our team designs, develops, and rigorously audits smart contracts for security vulnerabilities, ensuring your automated agreements are reliable, secure, and compliant. We review contract logic for reentrancy attacks, integer overflow, access control failures, and business logic flaws. Every smart contract we audit receives a comprehensive written report with severity-rated findings and remediation guidance, suitable for regulatory review and investor due diligence.
Comprehensive security reviews of blockchain protocols, wallets, exchanges, and decentralised applications. We identify vulnerabilities before bad actors can exploit them. Our methodology combines automated scanning tools with manual expert analysis, covering network security, consensus mechanism vulnerabilities, cryptographic implementation review, key management practices, and node infrastructure hardening. Findings are delivered in a boardroom-ready report with a clear risk register and remediation roadmap.
Advisory on security token offerings, NFT platforms, and digital asset custody solutions, ensuring regulatory compliance and robust security architecture. We help clients navigate MiCA, FCA digital asset guidance, and evolving global frameworks for token issuance. Our team designs compliant token structures, advises on custody solutions ranging from hot wallets to institutional-grade multi-party computation, and provides ongoing regulatory monitoring as the legislative landscape evolves.
Deep expertise in the Cardano ecosystem, including ADA staking pools, smart contract deployment via Plutus, and native token development. We operate EU01 stake pool supporting 350+ operators globally. Our Cardano practice covers stake pool operations and performance optimisation, Plutus and Marlowe smart contract development, native token creation and management, Hydra Layer 2 scaling solutions, and governance participation in the Cardano ecosystem.
Specialist Theta blockchain services including validator node operation, TFuel staking optimisation, and DApp development on the Theta protocol. Theta's decentralised video delivery network represents a significant use case for blockchain in media and entertainment. Our team provides node infrastructure setup, security hardening, performance monitoring, TFuel staking strategy, and smart contract development on the Theta protocol for streaming, NFT, and content monetisation applications.
Assessment and hardening of decentralised finance protocols, liquidity pools, and yield farming strategies against exploits, flash loan attacks, and governance vulnerabilities. The DeFi ecosystem has seen billions lost to exploits, many of which were preventable with rigorous pre-deployment security review. We conduct protocol-level security assessments, governance attack simulations, oracle manipulation testing, and liquidity pool risk analysis to protect your DeFi deployment and its users.
Navigating MiCA, FCA guidance, FATF travel rule, and AML/KYC obligations for blockchain businesses operating in regulated markets. Regulatory compliance is no longer optional for blockchain businesses. Our compliance advisory covers Markets in Crypto-Assets Regulation (MiCA) readiness, FATF Travel Rule implementation, AML/KYC programme design for VASPs, FCA crypto-asset registration, and cross-jurisdictional compliance mapping for globally operating blockchain businesses.
End-to-end delivery of private and consortium blockchain networks using Hyperledger Fabric, R3 Corda, and Ethereum enterprise frameworks. We manage the full implementation lifecycle from requirements definition and architecture design through development, testing, integration, and go-live support. Our enterprise blockchain engagements include change management advisory to drive adoption and maximise ROI from your distributed ledger investment.
Designing governance frameworks for DAOs, protocol upgrades, and decentralised organisations to ensure accountability and security. Effective governance is the foundation of a sustainable blockchain ecosystem. We design voting mechanisms, treasury management policies, proposal frameworks, and contributor incentive structures. We help DAOs balance decentralisation with operational effectiveness, ensuring your governance model is resistant to capture attacks, sybil attacks, and low-participation failure modes.
Pairing the best blockchain developers with the most progressive businesses. Our Cardano practice is led by professionals who have been active in the Cardano ecosystem since 2018 and in the broader crypto industry since 2013.
We operate the EU01 stake pool, providing security and performance monitoring for pools globally and supporting over 350 stake pool operators through dedicated Telegram channels, YouTube tutorials, and comprehensive online manual resources. As members of the Cardano Pioneer Family, we have hands-on experience with every major protocol upgrade.
Theta is a decentralised video delivery network and blockchain platform that enables peer-to-peer video streaming, NFT distribution, and DApp deployment. Our specialist Theta practice covers the full range of services that businesses and content creators need to leverage this network effectively.
From validator node operation and TFuel staking optimisation to DApp development and NFT platform creation, our team brings practical, hands-on Theta expertise to your organisation. We have experience across the Theta mainnet, the Theta EdgeCloud, and integration with traditional media technology stacks.
A structured, outcome-focused methodology developed across dozens of blockchain engagements.
We begin every engagement with a structured discovery phase: understanding your use case, evaluating whether blockchain is the right solution, and mapping the technical and regulatory landscape. We produce a detailed feasibility report that provides an honest, evidence-based assessment, including where traditional database or cloud solutions may serve you better. This intellectual honesty is the foundation of our client relationships.
For engagements proceeding to implementation, we architect the optimal solution for your requirements: selecting the appropriate protocol, designing smart contract logic, establishing governance mechanisms, and building the technical infrastructure. Our development team works in iterative sprints with regular client review points, ensuring the delivered solution precisely matches your operational requirements and passes rigorous security testing before deployment.
Before any deployment, we conduct a comprehensive security audit of all smart contracts, infrastructure, and integrations. We review your compliance obligations and produce documentation suitable for regulatory submissions. Post-launch, we provide ongoing monitoring, incident response planning, and protocol upgrade management to keep your blockchain deployment secure and compliant as the ecosystem evolves.
We'll help you to achieve your goals and grow your business.
