On Nov 13, 2026, Blockstream introduced a new Bitcoin custody system built in collaboration with Thales. Adam Back argued for offline safety measures to lower cyber risks, using dedicated hardware specifically for signing transactions. The report was authored by staff writer Nate Kostar and edited by Ana Paula Pereira for Cointelegraph.
This release arrived alongside price declines across multiple digital assets. Bitcoin decreased by 4.00% to $68,339.33, while Monero dropped 4.16% to $530.51 and Ethereum fell 2.49% to $1,934.67. Additional tokens such as BNB, XRP, and Solana stood at $631.61, $1.01, and $78.45 respectively.
The setup relies on dedicated hardware built to approve transaction signatures outside of online environments. Pushing key management offline is designed to reduce exposure to digital threat vectors.
For traders currently holding perpetual futures positions, this setup changes nothing directly regarding funding rates, platform fees, or margin requirements on exchanges. While offline hardware alters how underlying spot holdings are secured, active derivative contracts remain governed by individual exchange order books and risk engines.
