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

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

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.
