Recheck

Market position

ReCheck describes itself as a Dutch startup and a pioneer in blockchain-based data protection, verification and security solutions. It acts as an infrastructure and integration partner for other platforms rather than as a direct competitor to them, supplying blockchain modules to companies such as ipOcean, Block Materials and CoTown, and aligning with protocols including Ethereum, Aeternity, Concordium and the Internet Computer.

ReCheck positions its offering around plug-and-play integration requiring only a few lines of code, infrastructure and smart contracts it describes as already running in production, and a privacy-by-design architecture in which transparency does not conflict with confidentiality. Person-to-person encryption performed in the browser means the company itself cannot read customer data, and an independent verifier allows users to check blockchain trail hashes without depending on ReCheck. The company also states an open-source policy for part of its code and a preference for ecosystem solutions over end-point products.

Technology

The platform combines end-to-end, person-to-person encryption performed in the browser, anonymisation and masking protocols, and digital proofs (timestamps and hashes) recorded on blockchain or other ledger databases to create an immutable, verifiable audit trail. Encrypted data is stored on Amazon Web Services cloud infrastructure while identities are held encrypted on the user's smartphone under decentralised-identity and self-sovereign-identity principles with 12-word recovery phrases. Integrations and libraries span Ethereum and Aeternity digital signatures, the Concordium protocol, and the Internet Computer Protocol, with open repositories in JavaScript, TypeScript, Java, Vue, Kotlin, Swift, Rust and Solidity, including a client-side encryption library, a Java encryption library, a CLI tool, Vue authentication components, a native mobile app, a decentralised trail-hash verifier and DataPond tracing, storage and points canisters.

Go-to-market

The company reaches customers through direct enterprise engagement and partnerships, supported by visibility at industry conferences, hackathons and startup competitions across Europe. Developer adoption is supported by publicly available SDK documentation and open GitHub repositories, while the website directs enquiries to a contact form and states a one-business-day response commitment. Customer testimonials come from partner organisations that embedded ReCheck technology into their own platforms.

Businesses and public-sector organisations that need verifiable, privacy-preserving data exchange and audit trails, including platform operators integrating a blockchain module, real estate and building-materials firms, supply chain and product-authenticity use cases, education institutions issuing certificates, and developers embedding the SDK into existing software.
