Digital Signatures on Blockchain (SignRequest)

Digital Signatures on Blockchain

Providing immutable evidence by publishing the timestamped evidence on digitally signed documents.

Involved parties

Over 1 million business documents are signed every year through the SignRequest app.

Business challenges

Evidence of date and time

In case there ever is a dispute about the exact time a document was signed, you need to be able to verify this reliably.

Document authenticity

In case there ever is a dispute about which version of a contract was agreed and signed, you need to be able to validate which one is the original one.

Document verification

Documents that are shared and used by multiple parties need to be trusted by everyone involved, and independently verifiable.

Solution overview

Immutable PDF's

The document can be represented as a digital fingerprint by 'hashing' the document. LTO Network stores the hash of this document through a with LTO Network connected systems Anyone with access to the data can verify the document by hashing it and comparing it against the stored version.

LTO Network - Verifiable timestamp

Verifiable timestamp

Not only the hashed document (fingerprint) is stored on the blockchain but also the timestamp of the document. By making documents verifiable and independently auditable, they become more valuable. LTO Network creates portable proof of your timestamped claims. These blockchain-based verifications can be shared and transferred to other parties.

No need for third party verification

Using the on open standards-based LTO Network is, any party can independently verify the authenticity and timestamp of the document, without having to rely on a trusted third party.

The blockchain of LTO Network is optimized for anchoring, making transactions affordable and occurring at near-instant speed.

Traditional blockchains tend to be very slow. Anchoring transactions on them is expensive.

Using the blockchain for Proof-of-Existence of electronic signatures makes sense and is already happening. When we researched blockchain platforms, LTO Network stood out in terms of speed, set-up, and capabilities. We can include the blockchain transaction identifier directly into our signing logs which that circulate upon signing, without the need to wait minutes for confirmations. Moreover, the potential for creating decentralized workflows pushed us over the edge and made us add the LTO Network solution as an option to our users.
