Squire Announces Testing of Bitcoin SV Node

Vancouver, British Columbia, December 3, 2019 – Squire Mining Ltd. (CSE:SQR | FWB:9SQ |
OTCQB:SQRMF) (“Squire”) is pleased to announce it has successfully completed testing of the
latest version 0.2.2 (beta release) of the Bitcoin SV Node software using its custom cloud
computing management and pooling software (“Taal Orchestrator”) and a subfleet of 2,500
blockchain cloud computers. During the week‐long test period, Squire successfully processed
over 35 Bitcoin SV blocks. Testing was performed in collaboration with leading U.K. blockchain
research and development firm, nChain Limited (“nChain”), as part of the ongoing development
and services agreement between Squire and nChain announced by press release of Squire on
August 7, 2019. Testing is part of Squire’s plan to enhance Taal Orchestrator to optimize and to
develop internal controls for cloud computing fleets managed by Squire’s subsidiary, Taal
Technologies SECZ (“Taal Tech”). Taal Tech provides turn‐key management services and
oversight over enterprise‐scale global blockchain cloud computing operations, totaling over
200,000 ASIC cloud computers, or approximately 3,000 petahashes of computing power.

Bitcoin SV Node

Bitcoin SV Node software version 0.2.2 is a major milestone release featuring:

  • Parallel transaction validation, resulting in a 50% improvement in cloud computing
    speed
  • Incremental block assembly to support the building of bigger blocks and in support of
    transaction scaling
  • Internal block streaming to optimize system memory resources when processing bigger
    blocks

These features bring substantial improvements to the capacity of the Bitcoin SV blockchain and
pave the way for significant transaction scaling. Preliminary testing on the Bitcoin SV Scaling Test
Network shows an increase from a sustained 200 transactions per second in version 0.2.1 to
approximately 400 transactions per second with this version.

“This test is part of Squire’s leadership role in the adoption of Bitcoin SV to support large scale
enterprise applications on the blockchain with our state‐of‐the‐art mining infrastructure”,
remarked Joseph Chin, Chief Mining Officer and Corporate Secretary of Squire.

The Bitcoin SV Node software was developed by nChain on behalf of the Bitcoin Association, the
global industry organization supporting Bitcoin SV. The organization’s President, Jimmy Nguyen,
who is an advisor to Squire, commented: “We thank Squire Mining for helping to lead testing of
this beta release of Bitcoin SV Node version 0.2.2. This is another step in the Bitcoin SV Node
team’s ongoing technical work to achieve scaling improvements on the BSV main net, and
demonstrates that the original Bitcoin design could always scale to become the global enterprise
blockchain.”

Steve Shadders, Chief Technology Officer of nChain and Technical Director of the Bitcoin SV Node
software project commented: “The Bitcoin SV Node team is pleased to see Squire Mining taking
a leading role in the testing and deployment of improved scaling technologies. The business
model of miners and the entire Bitcoin industry is enhanced by increasing throughput to levels
that are beginning to rival traditional credit card payment networks.”
