Vancouver, British Columbia--(Newsfile Corp. - December 1, 2021) - HIVE Blockchain Technologies Ltd. (TSXV: HIVE) (NASDAQ: HIVE) (FSE: HBF) (the "Company" or "HIVE") is pleased to announce its investment in Titan.IO, Inc. ("Titan"), a cutting-edge blockchain software company and the creator of Lumerin, a next generation decentralized mining marketplace where hashpower can be bought and sold using tokens.

Today Titan offers software which helps Bitcoin miners increase their efficiency and scalability at a flat, low cost. It also operates the Titan Mining Pool, which recently surpassed 3 Exahash of Bitcoin mining capacity.

Titan has also announced a disruptive decentralized hashpower routing protocol named Lumerin. The open source Lumerin Protocol is a peer-to-peer solution that enables the exchange of hashpower through smart contracts, making crypto mining hashpower tradable and liquid.

The Lumerin Protocol will allow companies and individuals to buy, sell, and deliver hashpower, achieving decentralization through free market dynamics. Furthermore, the Lumerin Protocol will make Bitcoin hashpower a tradable, liquid financial asset, unlocking mining profitability and providing greater access to capital and hedging strategies.

The investment in Titan has been structured as a share exchange where HIVE will issue to Titan securities consisting of shares and warrants having a value of USD $5 million at CAD $6/share, the same terms as the recently-announced private placement. Titan will issue to HIVE common shares in an amount representing 10% of the outstanding equity of Titan. The transaction is pending TSX Venture Exchange approval.

Other investors in Titan include Coinbase Ventures and Fenbushi Capital.

HIVE's investment in Titan will mark the Company's fourth equity investment of the year. Previous investments include DeFi Technologies, Network Media Group, and a seed investment in Tokens.com.

HIVE Executive Chairman Frank Holmes strongly endorses the Titan team, stating: "We're backing an extremely strong technological team at Titan, led by expert 15-year veteran software coder CEO Ryan Condron. We were also impressed by Matthew Roszak, co-founder and chairman of Bloq, a leading enterprise software blockchain company. And co-founder Jeff Garzik was an early Bitcoin core developer. HIVE wants to participate in growth in the blockchain ecosystem such as mining software, transparent pools and innovative new tokens, and this is another strategic way to do that. We look forward to working with Titan to capture new opportunities as Bitcoin mining power shifts from China to North America."

Ryan Condron, Titan's CEO and Co-Founder, echoed Frank's sentiment. "We're very excited to be partnering with HIVE. We founded Titan in order to maximize the optimization and decentralization of mining at any scale. In that journey, we have greatly appreciated HIVE's expertise and leadership in the mining space. We look forward to working with them to maximize mining efficiency and transform hashpower into a global tradeable commodity using the Lumerin Protocol."
