One Type of Post-Quantum Cryptography Is Most Popular. Why Is Crypto Trying Out Three? 🥷 Bitcoin's unmigrated Satoshi-era coins are quantum computing's biggest test for crypto. Do nothing, and a quantum attacker could dump millions of BTC onto the market. @P3b7_ prefers a third path instead: freeze the coins and tail-emit new BTC to compensate for the security budget problem. @ilblackdragon and I agree it makes sense. ⚖️ Timestamps: 🔐 02:18 Illia and Charles map Shor's algorithm leap and EigenLayer's 48-hour crack 🧠 12:43 Why Matt Corallo's Bitcoin core skepticism reveals NEAR's design edge 📢 18:18 1inch Aqua: see how the shared liquidity platform works at 🔀 23:28 How lattice vs hash based crypto split Ethereum from Bitcoin's plan 🌐 34:46 Charles: why this crypto fight is unique to blockchain, not elsewhere 🛠️ 37:04 Charles walks through Ledger's SDK and hardware wallet quantum roadmap 🔑 44:22 Why 'wrench attacks' expose the physical risk in quantum signing 🕵️ 46:11 Charles debunks the harvest now decrypt later myth for blockchains ₿ 54:52 The Satoshi's coins dilemma: three options and Bitcoin's security budget

your agent should be able to pay, not sign blindly That’s why I built Agent Pays Agent. An AI agent initiates a 0.01 USDC payment through x402, but approval goes through a @Ledger signing flow first. Agent asks. Human reviews. Ledger signs 🔐 #LedgerSponsor# #Sponsored#

Have you ever approved a transaction you didn’t understand? Backed by the @ethereumfndn and the Clear Signing Working Group, you can get absolute clarity before confirming with Clear Signing and Transaction Check.

BITCOIN RAILS #70#: THE CASE FOR LATTICE-BASED SIGNATURES IN BITCOIN | with CTO of @Ledger Charles Guillemet 🔗 YouTube: 🌿 Spotify: To date, post-quantum Bitcoin discussions have largely centered on which digital signature schemes offer the strongest cryptographic security against a quantum adversary. But cryptographic assumptions are only one dimension of security. Different signature schemes introduce different implementation and operational risks. How should Bitcoin weigh cryptographic conservatism against the complexity required to deploy that cryptography safely? While hash-based signatures are often favored for their conservative assumptions, CTO of Ledger, Charles Guillemet @P3b7_ argues that evaluating primitives in isolation can obscure consequential risks at the systems level. Stateful hash-based schemes, in particular, introduce state-management requirements where operational or user error can have catastrophic consequences —despite their conservative cryptographic foundations. In this interview, Charles and I examine the tradeoffs of hash-based signatures and his case for greater consideration of lattice-based alternatives, i.e. ML-DSA.

We agree so much we already did it. Last October at Op3n we retired "hardware wallet" for "signer," and Ledger Live became Ledger Wallet. Two words, two jobs. The signer is the hardware that proves intent and consent. The Wallet is where you actually buy, swap, and stake. And signers matter even more now. Deepfakes can clone your face and your voice. They still can't press your button.

Too many people keep their crypto spread across random apps, exchanges, and software wallets. Chaos. Ledger keeps it simple: buy and manage everything inside Ledger Wallet, and let your Ledger signer hold your keys offline. One setup. Zero compromises. 🔒
