Liquid Network Returns Bitcoin to 1:1 Ratio
Liquid, a network operated by Blockstream, has restored its bitcoin to 1:1 ratio after an attack that created 4,000 L-BTC without backing. The attacker had returned 3,400 L-BTC, leaving about 600 BTC missing. The final transfer of 250 BTC closed the gap, with the source of the funds undisclosed. Withdrawals remain under strengthened controls.
