A brief step-by-step
Quick guide to signing with our blockchain
Upload your document
When you upload your document, it is automatically registered on the blockchain, which gives it a unique and unchangeable identifier. This process ensures that any future modification attempts are easily detectable, providing a layer of security from the very first moment.
Generate the immutable signature
Once you decide to sign, a unique digital signature is created and linked exclusively to that specific document. This signature is impossible to replicate or forge and is protected on the blockchain, permanently ensuring its integrity and authenticity.
Perpetual protection
From the moment the document is signed, it cannot be altered without every change being recorded on the blockchain. This guarantees a transparent and tamper-proof history, giving all parties the confidence that the document remains intact and verifiable over time.
