On 12 March 2013, a bitcoin miner running version 0.8.0 of the bitcoin software created a large block that was considered invalid in version 0.7 (due to an undiscovered inconsistency between the two versions). This created a split or “fork” in the blockchain since computers with the recent version of the software accepted the invalid block and continued to build on the diverging chain, whereas older versions of the software rejected it and continued extending the blockchain without the offending block. This split resulted in two separate transaction logs being formed without clear consensus, which allowed for the same funds to be spent differently on each chain. In response, the Mt. Gox exchange temporarily halted bitcoin deposits.[172] The exchange rate fell 23% to $37 on the Mt. Gox exchange but rose most of the way back to its prior level of $48.[43][44]

After a month-long jury trial that ended in Ulbricht’s conviction, Judge Katherine Forrest sentenced Ulbricht to life in prison without parole.

In a letter to Judge Katherine Forrest prior to his sentencing, Ulbricht admitted to running the Silk Road and made a plea for leniency.
