Telegram Desktop: one-click account takeover via IPC injection beaksec.github.io/posts/tele…

Today I call upon the blockchain industry to calmly begin planning for "bunker mode". My personal recommendation is to set in motion a controlled mass migration of assets to fresh addresses, i.e. addresses whose pubkeys remain hidden behind a hash. Holders, starting with large and sophisticated ones, should consider moving the bulk of their funds to addresses that have never signed a transaction. And when they do sign one, they should also move remaining funds to a new address (possibly generated from the same seed phrase). Don't rush. While I believe there is cause for action a rushed migration would do more harm than good. Don't panic either. Moving assets to protected addresses is a simple, preventative step which does not require new cryptography or new wallets. IMO it is now reasonable to brace for the possibility that ECDSA breaks before qday, in the worst case in months not years. By "break" I mean fast private key recovery (e.g. in one week) on available hardware (e.g. a large GPU cluster). Recent days have been humbling for human mathematical intuition. Long-held, unquestioned hypotheses have fallen. This includes the n log(n) bound for integer multiplication and the 3SUM conjecture. In hindsight, May's unexpected disproof of the Erdős unit distance conjecture was our warning shot. Yesterday's OpenAI drop made it clear that mathematical superintelligence is upon us. They say there are weeks where decades happen. We are about to live through weeks where centuries of mathematical progress happen. Could our magic 64-byte ECDSA signatures be too good to be true? Was it just security through obscurity all this time? Elliptic curves feel especially vulnerable to superintelligence. Curves carry rich structure, with room for fancy tricks like Schoof, Frobenius, pairings. (By contrast, hashes are designed to minimise algebraic structure.) Separately, as Ewin Tang can attest, an efficient quantum algorithm sometimes foreshadows an efficient classical one. We should be open to the possibility of a classical counterpart to Shor that breaks elliptic curves and RSA at once. Also noteworthy is the striking under-representation of cryptographic breakthroughs among the 722 mathematical results OpenAI published. I've witnessed first-hand the US government censoring academic quantum cryptanalysis results. Backroom interventionism is my base case. I urge large, sophisticated actors to lead by example. Project11's "risq list" (bitcoin-risq-list.projecteleven[.]com) is a great tracker of exposed BTC pubkeys. Binance, Bitbank, Robinhood, Bitfinex, and Tether have an opportunity to harden their cold storage. Next month I'll address institutions in London in a live Q&A (forum.ethereuminstitutional[.]org/london-2026). Again, please do not rush. Wallets holding under 50 BTC enjoy partial cover from "Satoshi's shield", i.e. his 20K exposed addresses that hold 50 BTC each. Load-bearing signers like oracles and L2 security councils should consider rotating ECDSA pubkeys with every signed message and/or multi-signing with a hash-based schemes like SPHINCS. Exiting bunker mode safely will require post-AI cryptography. My inclination is to go all-in on hash-based cryptography and avoid structured mathematical assumptions entirely, whether from curves, lattices, or isogenies. A single battle-tested hash (e.g. from the SHA or BLAKE families) yields plausible post-AI security. The Ethereum roadmap on strawmap[.]org fully embraces hash-based cryptography with end-to-end formal verification as a response to the quantum threat. Those timelines must now be revisited and accelerated in light of mathematical superintelligence. I'll be pushing for maximum defensive acceleration.

Category Labs is proud to introduce Cadence, our multiple-concurrent-proposers (MCP) consensus protocol that matches the optimal good-case latency of single-leader consensus while supporting arbitrarily short block intervals. When combined with BTX, our design for encrypted mempools, this represents a significant step towards solving the problem of MEV at the protocol level. In nearly every blockchain today, a single party ends up in control of each block: it decides which transactions get in, and can reorder them at will. MCP is the natural fix, but most recent designs pay for it with a separate aggregation phase, adding two extra communication rounds per block. Cadence makes the proposers part of consensus itself. Its fast path finalizes in an optimal three communication rounds, even when proposers are offline. Cadence also offers speculative finality, similar to MonadBFT, after just two rounds, revertible only if a proposer provably equivocated. In a simulation using estimated network delays between Monad mainnet's 200 globally distributed validators, finalization takes 219 ms on average, speculative finality 167 ms. Cadence pushes pipelining to the extreme: each block is proposed and finalized in its own independent consensus instance, without waiting on preceding blocks. The block interval then becomes a protocol parameter that can be arbitrarily small. At our initial target of 100 ms, a transaction waits on average just 50 ms to enter a proposal, and oracle prices, liquidations, and auctions can update every 100 ms. Cadence dynamically throttles the opening of new instances to bound the number of outstanding slots even during periods of network instability. When the network is healthy (under synchrony), a transaction included by an honest proposer can be neither dropped nor deferred (short-term censorship resistance), and no proposer can see the others' proposals in time to react (hiding). We prove both, together with safety and liveness under partial synchrony at the optimal 3f+1 fault bound. The Cadence protocol is modular: each module is simple on its own, and any of them can be swapped out without touching the rest. Cadence also builds on components already being deployed: proposals are disseminated as erasure-coded chunks over Deterministic RaptorCast, now rolling out on Monad, and validators vote on proposal digests, so voting does not wait for the full data to arrive.

The Last General-Purpose L1 The title hits home for me. Monad has been 4.5 years in the making, and it still feels like we’re just getting started. But when we set out in 2022 to build the right system from first principles, conditions and industry beliefs were very different. There is significant path-dependence, and I do feel we were lucky to acquire the resources and talent, and have the breathing room to truly innovate, to build the Monad of today. Monad is a general-purpose L1. I believe that no other L1 comes close to the level of reliability, performance, fairness, and decentralization. And I believe that there are significant advantages to concentrating all the network effects of DeFi, payments use cases, fintech integrations, asset availability, consumer experiences, and capital formation on a single shared global state, built on a decentralized and neutral network. It’s a bold bet, for all the marbles, and it’s one that almost no one is taking today. Almost every L1 or L2 that you see has pivoted into building a single first-party app. And the few new chains are corporate chains, running commodity tech and run by employees of a company with shareholders to answer to. Corporate chains get a boost from their existing distribution (or perhaps from crypto-natives anticipating that they will utilize their existing distribution). But what is built is inherently limited. The existence of an anchor tenant dissuades competitors of the anchor from integrating. Neutral is the right tack for a network that dreams of delivering universal access to finance. But neutrality is tough sledding these days. It requires years of prerequisite work, truly unique tech, a community of believers, and adequate resources to go the distance. Monad stands alone. It is a grand experiment, in which to succeed the ecosystem must outperform everything that came before. Better execution, better asset availability, better opportunities, fairer outcomes. I relish the challenges ahead.
