Twala Hashproof Technology:
Advanced Cryptography for Securing Your Documents
In today’s digital world, securing documents is a top priority. From contracts to certificates, we rely on documents to carry our most important decisions and milestones. But how do we ensure these documents are protected against tampering, forgery, or loss? Enter Twala Hashproof Technology—a cutting-edge solution that combines advanced cryptography, blockchain innovation, and compatibility with traditional security standards to secure your documents in a way that's both powerful and easy to trust.
What is Hashproof Technology?
Twala’s Hashproof Technology uses advanced cryptographic algorithms to create a unique digital “fingerprint” for each document, called a hash. A hash is a string of numbers and letters generated by a cryptographic function, ensuring that even the smallest change to a document results in a completely different hash.To provide an extra layer of security, Twala organizes these hashes into a Merkle Tree—a cryptographic structure designed to efficiently secure large volumes of data.
The Merkle Tree: A Cryptographic Masterpiece
Think of a Merkle Tree as a digital "family tree" for your documents:

‍Leaves: At the bottom of the tree are the individual document hashes, each representing a unique digital fingerprint.

‍Branches: The hashes are paired and combined using cryptographic functions to form new hashes, which are then paired and hashed again.

‍Root: At the top of the tree is a single root hash—a cryptographic summary of all the documents.

This structure makes it easy to verify the integrity of any individual document by tracing it back to the root hash. If even one document is altered, the root hash changes, immediately signaling tampering.
Securing Individual Document Hashes with Digital Signatures
Twala takes document security a step further by encrypting the individual document hashes using digital signatures created with the private keys of the signers.
Why Digital Signatures?

Digital signatures are an essential part of electronic signature systems, ensuring compliance with laws like:

- The Philippine E-Commerce Act
- The Supreme Court Rules on Electronic Evidence
- Similar regulations in jurisdictions around the world

These laws require that electronic signatures:

1. Be uniquely linked to the signer.
2. Use cryptographic methods to prevent tampering.
3. Enable verification of the signer’s identity and the document’s integrity.

By encrypting the document hashes with the signer’s private key, Twala ensures that:

- The signer’s identity is authenticated.
- The document is protected against tampering.
- Any unauthorized changes to the document invalidate the signature.

The encrypted document hashes are then incorporated into the Merkle Tree, ensuring their tamper-proof status while providing a way to validate the document’s integrity in compliance with legal standards.
Recording the Root Hash on Blockchain
To ensure the overall security of your documents, the root hash of the Merkle Tree—a summary of all individual encrypted document hashes—is recorded on the blockchain.Blockchain is a decentralized, immutable ledger powered by advanced cryptographic protocols. Once the root hash is recorded, it cannot be altered, creating a permanent, auditable chain of trust.
A System That Grows More Secure Over Time

Each root hash is linked to the next in a chain, forming a cryptographically secure record of your documents. As more hashes are added, the chain grows longer, making it exponentially harder for anyone to compromise its integrity. This ensures your documents remain secure over time.
The Role of Advanced Cryptography
Twala’s Hashproof Technology incorporates state-of-the-art cryptographic techniques, including:

1. Secure Hash Algorithms (SHA): To create tamper-proof digital fingerprints of documents.

2. Elliptic Curve Cryptography (ECC): For secure, efficient encryption and signing.

3. Blockchain Cryptographic Protocols: To guarantee the immutability of root hashes.

4. Digital Signatures (Private/Public Key Pairs): To authenticate signers and comply with electronic signature laws.

5. X.509 Certificates: For seamless integration with traditional digital signature systems.

This combination of blockchain, advanced cryptography, and digital signature standards ensures your documents are secure, compliant, and future-proof.

Compatibility with Traditional Digital Certificates
While Twala leverages blockchain to provide modern document security, it’s also compatible with traditional digital certificate technology based on the widely used X.509 standard.

As a proud member of the Cloud Signature Consortium (CSC), Twala adheres to global standards for cloud-based digital signatures, ensuring interoperability with Public Key Infrastructure (PKI) systems and compliance with international regulations. This membership reinforces Twala’s commitment to providing secure, legally recognized digital signatures that are accessible and reliable.

This dual approach allows Twala to meet the needs of organizations adopting blockchain technology while supporting those relying on established PKI systems, bridging the gap between traditional and modern document security solutions.
