Liquid

White hat hackers targeted Blocksteam's Liquid sidechain, taking over 4,000 bitcoins. They want to keep some of the bitcoins as a reward. Blockstream isn't happy.

A self-described white-hat party returned 3,400 BTC to Liquid Network’s federation wallet on Monday after Blockstream said bridge nodes were patched. About 598.5 BTC, near $47 million, remains at the holder address.

Liquid Network said purported white-hat hackers withdrew about 4,000 bitcoin from the federation wallet that backs L-BTC. Bridge nodes are disabled and the sidechain is paused.

Bitcoin remains pseudonymous by design, but real-world threats from exchanges and data leaks demand stronger protections. Experts highlight Sparrow Wallet, Bisq, and Boltz as key 2026 solutions for on-chain and off-chain privacy.

Paystand, the Bitcoin-powered B2B payments network processing over $20B in volume, today launched USDb, a 1:1 USD-backed stablecoin native to Blockstream’s Liquid and Rootstock layers for commercial-scale accounts receivable, payable, payroll, and treasury.

Second, the Bitcoin development lab founded by ex-Blockstream executives including CEO Steven Roose and CTO Erik De Smedt, has unveiled Bark — its custom Ark protocol implementation promising self-custodial payments that are faster and cheaper than Lightning channels.

Kilian of Boltz reveals exclusive details on bridging Bitcoin's onchain, Lightning, Liquid, and Rootstock layers without trust, amid high-fee environments driving adoption.

The Boltz BTCPay Plugin enables merchants using BTCPay Server to accept Lightning payments non-custodially and transfer these funds to the Liquid sidechain.

The club is also aiming to educate fans on Bitcoin, teach them how to use it for team purchases and more.

The debate around the next change to Bitcoin is focused almost entirely on covenants. Having already implemented numerous covenants, Liquid presents a great learning opportunity in that discussion.
