mintBlue

Founded in 2020 and based in Amsterdam, mintBlue builds blockchain data infrastructure for enterprises, writing records to the public Bitcoin SV ledger through an API that plugs into existing finance and business systems. The mechanical pain point it targets is that data exchange between companies runs through separate centralised databases, so invoices, audit trails and credentials cannot be verified across systems and any later trace depends on files the counterparty exports.

Technically it writes the hash and metadata of each file, invoice or business event into an on-chain transaction to fix a timestamp, and carries the invoice itself in an NFT so the document keeps uniqueness and a verifiable transfer history; invoice content can be encrypted on chain and decrypted by the paying party into their own bookkeeping. It has processed more than 700,000 NFT invoices for the European cloud accounting provider Visma|yuki, ran a proof of concept with Storecove, the largest Peppol access point in the Netherlands, embedding blockchain into the Peppol client, and ran a proof of concept with the Dutch Chamber of Commerce on verifying the identity of invoice issuers. It is positioned as a BSV-ecosystem supplier treating a public ledger as the enterprise data layer.
