He invented the proof-of-work algorithm cited in the Bitcoin whitepaper. Dr. Adam Back @adam3us, Co-founder and CEO of @Blockstream and @bstrco, takes the Proof of Talk stage this June. Adam created Hashcash, the proof-of-work system Satoshi Nakamoto referenced as the foundation for Bitcoin's mining function. A contribution that placed him among the small group of cryptographers whose work made Bitcoin technically possible. His two-decade career as an applied cryptographer and security architect includes senior roles at Microsoft, EMC, VMware, and Zero-Knowledge Systems, alongside advisory work for many other companies on cryptography and peer-to-peer finance. He holds a PhD in distributed systems from the University of Exeter, and co-founded Blockstream, which today builds critical infrastructure underpinning the Bitcoin ecosystem. The Louvre Palace, June 2 & 3.

Optimized stateful hash-based signatures can offer better trade-offs than the standard schemes available today. SHRINCS is live on @Liquid_BTC in production today via Simplicity. @n1ckler at @OPNEXT2026 on why this may allow Bitcoin to operate in a post-quantum world without betting on specific future software.

SHRINCS reaches up to 3 TPS on the compact path. 580-byte signatures from a dedicated signing device. A stateless fallback always available. Already demonstrated on @Liquid_BTC. The C++ implementation, Simplicity verifier, & draft spec are all on GitHub.

There is no concrete post-quantum signature scheme for Bitcoin today. But over the last year @blksresearch has been working on exactly this. Director Jonas Nick (@n1ckler) lays out the proposal: OP_CHECKSHRINCS, a hash-based signature opcode for post-quantum Bitcoin.

The next bull run isn't waiting for you to get your self-custody sorted. In the latest Exit Manual, @kinetic_finance brings a message from the future explaining where we are in the cycle and why you'll need a @BlockstreamJade in your hands.

ICYMI: @Blockstream shares an update on Liquid’s development roadmap. 0-conf and @bitcoincoreorg parity Quantum-ready testnet by EOY BitVM-style 1-of-n bridge research Oracle, DEX and other DeFi infrastructure Review the full roadmap. 👇

Your 2FA deserves the same protection as your Bitcoin. In its latest firmware update, @Blockstream Jade Plus can now serve as a PIN-protected hardware backup for your 2FA accounts. Back up your Google Authenticator accounts onto Jade. Export your OTP records whenever you need to.

As the @Liquid_BTC network’s tech provider, Blockstream is sharing an updated roadmap for the core development workstreams it leads. 0-conf, quantum readiness, BitVM exploration, institutional custody, P2P lending, and much more are in development.

The quantum threat to Bitcoin may still be a decade away, but @blksresearch is already working on the solution. Adam Back (@adam3us) joined @FINTECHTVglobal at @consensus2026 Miami to explain how Bitcoin will be ready before quantum becomes a threat.

"Bitcoin has no undo, it's a bearer asset. Bitcoin's reliance on cryptography is another level, because it's bearer and final." @adam3us on why Bitcoin and traditional finance are fundamentally different, and why quantum readiness doesn't need to happen overnight.
