eClosing and eVaulting (ProvenDB)
OneSpan is a Web3 platform that offers a dedicated eClosing solution designed to digitize and secure the entire lifecycle of high-value digital agreements, particularly in the mortgage and lending industries. The platform streamlines the closing process by enabling remote online notarization (RON), electronic signatures, and identity verification, all within a secure and compliant digital environment. A central component of this solution is the OneSpan eVault, a specialized repository for managing the authoritative copy of critical digital documents, such as promissory notes (eNotes).
To provide an unparalleled level of trust and auditability, OneSpan has integrated its platform with ProvenDB, a data integrity service built on the Hedera network. When a document is signed or a key milestone is reached in the eClosing process, a cryptographic fingerprint (hash) of the agreement is anchored to the Hedera public ledger. This action, facilitated by ProvenDB, creates a permanent and immutable timestamped record on the Hedera Consensus Service (HCS).

Hashlog is a data verification service that leverages the Hedera Consensus Service (HCS) to create immutable events or data logs. It enables applications and enterprises to submit messages to the HCS, where each message receives a consensus timestamp from the Hedera network, ensuring its integrity and order. This process provides a secure and transparent "proof-of-action" or "proof-of-event" capability.
Its core functionality offers a data trail for on-chain information. Once data is logged via Hashlog to the HCS, it cannot be altered or retrospectively tampered with, providing a high degree of data integrity. This is particularly useful for use cases requiring regulatory compliance, dispute resolution, or the tracking of critical operational processes. Developers integrate Hashlog systems using APIs or SDKs.
By utilizing Hedera, Hashlog provides decentralized trust, cryptographic verification, and public accessibility (if desired) for the logged information. Its applications span across multiple domains, including supply chain management for tracking goods, IoT data streams for device event verification, and legal tech for timestamping documents.
