Liquid recovers 3,400 BTC as hacker asks “is that ok?” after pocketing $47 million in Bitcoin

Bitcoin’s Liquid sidechain obtained 3,400 BTC again into its federation pockets on Sept. 7 after a reserve drain. The partial restoration restores property behind L-BTC, its Bitcoin-linked token, whereas withdrawal entry stays unconfirmed and public bridge nodes are nonetheless listed as experiencing a significant outage.

The recovery transaction confirmed at 16:09:25 UTC in Bitcoin block 965950. By press time on Sept. 8, Blockstream’s status page nonetheless listed an lively Liquid safety incident and a significant outage affecting public bridge nodes.

That leaves holders with two separate questions: how a lot Bitcoin is on the market to again their tokens, and after they can redeem them.

Before the reimbursement, the self-described white-hat hackers wrote in an on-chain message that they have been “sending most again” to Liquid’s federation handle, asking “is that okay.”

The subsequent transaction returned 3,400 BTC to the federation pockets and despatched roughly 598.5 BTC, price roughly $47 million on the time, again to the hackers’ handle. The public proof reviewed doesn’t set up that this retained quantity was an agreed bounty.

CryptoSlate’s earlier coverage put the unique federation outflow at roughly 3,996 BTC. The later restoration transaction spent roughly 3,998.5 BTC from the holder handle.

The return adopted one other on-chain patch message at 09:41:26 UTC on Sept. 7, stating that bridge nodes had been patched and that funds have been secure to return. This reconstruction experiences that its signature verifies towards Blockstream’s safety key. The patch declare doesn’t set up that withdrawal companies had reopened.

The remaining check for holders

Liquid’s documented redemption process burns L-BTC and releases Bitcoin by means of the federation. Ordinary customers typically want a certified member or service to transform their L-BTC again to BTC.

The returned cash add property to the backing pockets. Establishing full backing requires reconciling recoverable reserves with reliable excellent L-BTC. The 3,400 BTC switch alone doesn’t provide that accounting.

Operational entry additionally depends upon companies reopening. In its Sept. 6 incident statement, @Liquid_BTC stated bridge nodes had been disabled and exchanges had paused or would pause L-BTC deposits and withdrawals.

That day, @side_swap said its swaps, peg-ins and peg-outs have been paused till Liquid resumed. It requested customers to not ship new peg-in or peg-out deposits till it introduced companies have been again.

Exchange withdrawal entry nonetheless requires affirmation from particular person companies. With Blockstream’s dashboard itemizing the bridge outage on Sept. 8, a confirmed restart and a reserve reconciliation stay the subsequent assessments of whether or not holders can convert their L-BTC again to Bitcoin in full.

Approximately 598.5 BTC remained on the hackers’ handle at press time.
