Blockchain Signing involves using blockchain technology to record and verify digital signatures in a secure, tamper-proof manner. In the context of eSignatures, blockchain signing creates an immutable ledger of each signing event, ensuring that every signature and document change is permanently recorded on the blockchain. This method enhances transparency and security for digital transactions, making it particularly valuable for industries with strict compliance needs like healthcare, finance, and legal services.

Why is Blockchain Signing Important in eSignatures?

• Tamper-Proof Records: Once a signature is recorded on the blockchain, it cannot be altered or deleted, providing a permanent and tamper-resistant record of the signing event.
• Decentralized Verification: Unlike traditional methods that rely on a central authority, blockchain signing enables peer-to-peer verification, reducing reliance on third parties.
• Enhanced Trust: Blockchain’s transparency ensures that all parties involved in a digital transaction can verify the integrity of the signed document, fostering greater trust between stakeholders.
• Compliance: Meets the requirements of data integrity and auditability mandated by regulations such as eIDAS in Europe and ESIGN Act in the U.S.

Key Features of Blockchain Signing in eSignature Platforms

• Immutable Audit Trail: Every signature and document modification is recorded on the blockchain, creating a traceable history of all actions.
• Cryptographic Hashing: Uses hash functions to create a unique identifier for each signed document, which is then stored on the blockchain to verify authenticity.
• Decentralized Storage: Instead of storing documents in a single database, blockchain signing allows for distributed storage across a network, improving security.
• Smart Contracts: Enables the use of smart contracts to automate workflows and ensure that signatures or approvals are executed based on predefined conditions.

Certinal eSign’s Blockchain Signing Features

• Immutable Records: Certinal eSign uses blockchain technology to create tamper-proof records of every signature, ensuring that any attempt to alter a signed document is detectable.
• Cryptographic Security: Certinal applies cryptographic hashing for every signed document, storing these hashes on the blockchain for future verification.

FAQs

1. What type of eSignature uses blockchain technology?

Digital signatures that require enhanced verification and tamper-proof records often use blockchain technology to ensure that each signing event is securely recorded and cannot be altered.

2. Is blockchain signing secure?

Yes, blockchain signing is highly secure because it uses cryptographic hashing and decentralized storage to ensure that records of signing events are immutable and can be verified by any authorized party.

3. How does blockchain signing work in eSignatures?

Blockchain signing works by generating a cryptographic hash of the signed document, which is then recorded on the blockchain. This hash serves as a unique identifier for the document, allowing anyone to verify its authenticity and check for any alterations.

4. What is an example of blockchain signing?

An example of blockchain signing is when a healthcare provider uses Certinal eSign to obtain a digital signature on a patient consent form. The signed document’s hash is recorded on the blockchain, ensuring that any party, such as regulators, can verify the integrity of the signed document without accessing its actual content.
