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.
ICYMI: Simplicity, Liquidβs high-assurance smart contracting language, has a newly redesigned documentation site. It includes a testable lending contract that lets users borrow against assets such as LBTC and USDT.

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.
Satoshi chose secp256k1 for Bitcoinβs 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! π
DahLIAS enables cross-input signature aggregation (CISA) on Bitcoinβs secp256k1 curve.
See you in Rome, May 10β14!
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.
