ChainCatcher reports that, according to TheMinerMag, early Bitcoin developer Adam Back and two associated companies are requesting the U.S. court to enforce a $28 million arbitration ruling against the Chinese mining chip manufacturer Innosilicon.

According to the lawsuit, Innosilicon was aware of hidden cracks in the chips several months before delivery in March 2018 but still completed delivery in September 2018. The Hong Kong International Arbitration Center ruled that Innosilicon violated all three contracts, ordering compensation: 425.98 bitcoins to Blockstream, 1,393.79 bitcoins to Thigmotropism, and 51.84 bitcoins to Back.
