vChain Inc, the Immutable Data Specialist, Completes the Acquisition of Ledger and Log Compliance Company Opvizor

Houston, November 11, 2020

vChain Inc, the leading Open Source company for immutable ledger solutions, today
announces the closing of the acquisition of Opvizor Inc, a U.S. ledger and log
compliance software company.

Moshe Bar, CEO and co-founder of vChain, commented: “Businesses have expressed
their need loud and clear for immutable ledger solutions to guarantee the integrity of
their transactional systems and bring trust into their applications and data. The
integration Opvizor’s ledger and log integrity applications helps us advance our mission
with our customer base and the market in general. With an excellent match of
engineering skills and operational excellence, our two teams have integrated
seamlessly.”

Opvizor Inc, a venture capital-backed company, provides integrity and trust solutions to
hundreds of enterprise customers worldwide like Motorola, Docusign, and the US State
Dept. Opvizor has been cash-flow positive for several years, with operations in the U.S.
and central Europe.

Both companies have been partnering already over the last year for the resale of
vChain’s CodeNotary Ledger Compliance®
solution to Opvizor’s extensive international customer base.

CodeNotary Ledger Compliance® provides customers a tamperproof ledger solution
which enables the immutable recording of sensitive data through the same
cryptographic verification of traditional distributed ledger solutions. It is easy to use, runs
on-premise or in the cloud, and is able to process millions of transactions a second.
CodeNotary Ledger Compliance® is built on top of vChain’s immudb, the industry-
leading, lightweight Open Source immutable database.

“By combining Opvizor’s strength in log data collection, storage, and compliance using
open source software with vChain’s unique solutions for data immutability, we will
merge cloud-native technology with tamperproof data structures and jointly disrupt the
market to help customers accelerate their digital transformation with true open source
solutions,” said Dennis Zimmer, founder of Opvizor and CTO of vChain.

About vChain

The company was founded in late 2018 in Houston, Texas. vChain employs a team with
deep expertise in trust and integrity technology, cryptography, distributed ledger
technologies, immutable databases, and certificate management, distributed in over 12
different countries.

Use Case - Tamper-resistant Clinical Trials

Goal:

Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).

Implementation:

immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance

Goal:

Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.

Implementation:

While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace

Goal:

No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


Implementation:

immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data

Goal:

IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.

Implementation:

immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence

Goal:

CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.

Implementation:

As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
