JUSTIN SUMNER

Principal

Born and raised in North Yorkshire, England, gaining a scholarship to Ashville College, Harrogate prior to signing for Leeds United at 17 years of age. He made his Football League first team debut for Doncaster Rovers at 18 years in a brief 3-year professional career. Joining Aviva Insurance, then Willis Group for two years in Willis' Risk Management division, gaining Chartered Insurance Institute qualifications before moving to London to read Business Law at City St George, University of London.

Graduating with a comprehensive third year thesis on FIFA football player transfer rules and their reconciliation with European employment law following the European Court's "Bosman Ruling" case, he joined Fraser McGowan trading group, learning to trade derivative futures and options on the London International Financial Futures and Options Exchange (LIFFE). At this time, he also became the youngest FIFA approved players agent in the UK, notably identifying a UK player transfer loophole between UEFA, Premier League and Football Association rules.

Becoming a founding partner in a regulated inter-dealer broker firm, he helped build multiple desks in European spot and derivative futures & options products, dealing and settling large financial trades between the banks, hedge funds and trading groups. The firm became a leading European dealer in Equity Single Stocks & Indices, Short Term Interest Rates, Cash, Dividends and Commodity products. The firm became the top broker in DAX Index Options and a top 5 firm in Dividend Swaps, Delta One Strategies, FTSE 100 Index and Eurostoxx 50 Index Options markets.

Successfully navigating the great financial crisis, from 2013 he engaged in a five-year executive role as acting Chief Operating Officer with Texas electricity power generation firm MicroPower Global where he extended his knowledge of Bitcoin, promoting initiatives towards bringing electricity to rural communities in order to advance socio-economic well-being. A further five year engagement as a founding partner and Chief Commercial Officer with currency exchange trading technology specialists Aquarius Group AG of Zug continued his education of developing nation challenges from a monetary perspective, half his time being based in Mexico City.

In 2025, after completing his paper on digital monetary systems, he discovered a fault in Bitcoin hardware wallet designs that led him to invent a new security primitive. This achievement, now described in his white paper "Trustless Sovereign Identity, Recovery and Succession", created a solution for a long-standing puzzle in trustless succession, that of eliminating the seed phrase recovery vulnerability that all digital wallets hold. This allowed for not only trustless succession of Bitcoin or digital assets but for all physical assets too. The result of this innovative period, Justin's professional focus today supports patented proprietary ventures in Sovereign Infrastructure.
