According to CryptoWorld, Russia has imposed sanctions on 17-year-old British student Alexander Browder for his crypto research, which helped British officials target a ruble-backed stablecoin network accused of transferring funds for Moscow's war economy. Browder, son of Kremlin critic Sir Bill Browder, spent 18 months researching A7A5, a ruble-pegged stablecoin issued by Kyrgyzstan's Old Vector. According to Browder's research, A7A5 processed over $90 billion in transactions last year and is linked to the laundering of approximately $350 billion in illicit funds by rogue states. British Foreign Secretary Yvette Cooper stated that Britain is targeting the infrastructure supporting Russia's war economy. In an interview, Browder said the Russian sanctions did not intimidate him but rather indicated that his work had "touched a nerve."
