    Most people buy bitcoin first and secure it later. With Jade paired to the Blockstream app, every purchase lands straight in offline cold storage, secured by your hardware wallet from the very first transaction.

    Bitcoin is leaving exchanges, dominance is climbing, and institutional adoption is focused almost entirely on Bitcoin. @adam3us on why Bitcoin is at a good entry point.

    An unconfirmed transaction isn't lost, it's waiting its turn in the mempool, and the fee you paid is its place in line. In a hurry? Bump the fee in the Blockstream app to move up the queue.

    Today, losing your hardware wallet is fine. Your recovery phrase gets you back in. In a post-quantum signing setup, the device also holds state: a running count of how many times it has signed. That state matters for security. SHRINCS is designed so that if the device is

    The fallback needs no state, so a lost device is never a lost wallet. More expensive to spend from, but always accessible. @blksresearch Director @n1ckler on building a post-quantum scheme that stays safe even when hardware fails:

    Spending on @Liquid_BTC is going near-instant. 0-conf brings safe-to-act-on transfers, now in public beta with a full release around the corner. And with the issuance cap removed, issuers can mint stablecoins and other Issued Assets at real-world scale. The full Liquid roadmap

    Selling Bitcoin is typically dangerous. The price runs out of reach and you end up buying back higher. Or out of the market entirely. @adam3us on why Bitcoin investors are survivors.

    Stubborn or principled. Either way, your bitcoin belongs in self-custody.

    Satoshi chose secp256k1 for Bitcoin’s cryptography. @n1ckler and @blksresearch are among the co-maintainers of libsecp256k1, the library every Bitcoin node runs to implement it. Researching what comes next is a natural extension of that work.

    Bitcoin transactions could get cheaper by combining signatures across transactions. DahLIAS is a new signature scheme being worked on by @blksresearch, a building block for cross-input signature aggregation (CISA). Watch @real_or_random present DahLIAS in full at EUROCRYPT

    Excited to share that our DahLIAS paper has been accepted to Eurocrypt 2026! πŸŽ‰ DahLIAS enables cross-input signature aggregation (CISA) on Bitcoin’s secp256k1 curve. See you in Rome, May 10–14! Thanks to @yannickseurin (@Ledger), @real_or_random & @n1ckler (@blksresearch)!

    Full aggregation for BIP340 signatures, now as a draft BIP. It specifies DahLIAS, an aggregate signature scheme and can serve as a basis for future cross-input signature aggregation (CISA) proposals. Thanks to @fjahr for the spec work. More background on DahLIAS πŸ‘‡

    BIP draft: Full-Aggregation of BIP 340 Signatures by @fjahr πŸ‘€ groups.google.com/g/bitcoindev/c…
    Abstract

This document describes full-aggregation of BIP 340 signatures, a standard for the DahLIAS interactive aggregate signature scheme. Full-aggregation is an interactive process for aggregating a collection of signatures into a single aggregate signature. The resulting aggregate signature has the same size as a single BIP 340 signature (64 bytes), regardless of the number of signers.
