Introducing hash-based signatures into Bitcoin will meaningfully increase signature sizes — and reduce throughput, assuming no changes to block size. "I don't think we can only migrate to hash-based signatures without changing anything else. The size of the block might need to be changed," says @Ledger CTO @P3b7_ In the interview, he adds there may be alternative ways to manage signature size — e.g. using zero-knowledge proofs for signature compression —  but notes that this option would reduce security versus using a more efficient PQ signature scheme in the first place.

Gm gQuip Quantum computers can solve some problems that are difficult for normal computers. But there is one big challenge: access. Quantum machines are expensive, so most people and developers cannot own one. @QuipNetwork is working on a different approach: connect quantum and classical computers into a shared network so people can access computing power without owning the hardware. The goal is simple: Make quantum computing more accessible, not limited to a few powerful companies.

Your crypto security should not depend on whether you notice one wrong character. Yet that’s still how billions of dollars are moved every day. This Wednesday at 1:30 PM ET, @Americanfort_io to talk about phishing, address poisoning, the coming quantum threat, and why wallet security needs a completely different architecture. Don't forget to join in!

Random traits in digital collectibles usually start with a pseudorandom number generator. Quantum Echoes takes a stranger route. @quipnetwork uses verifiable quantum randomness to generate on-chain art, turning an output from specialized quantum hardware into something visible, ownable, and permanent onchain. A pretty unusual way to make quantum compute feel less abstract. Quantum Echoes mints on OpenSea - September 10.

Over the last two days we've covered the new EVM opcodes and the cryptographic precompiles landing with VIP-255. Today, part three, the finale: the core protocol improvements sitting underneath both. Part 3: Interstellar Explained - Core Protocol Improvements EIP-2935 - historical block hashes from state: Block hashes for the most recent 8,191 blocks served through a contract, using Ethereum's exact calling convention. Human version: VeChainThor always had the receipts, filed in its own system. This puts them in the drawer Ethereum tools already know how to open. How it changes VeChain: VeChainThor already holds that history in state through the Extension built-in contract, so lookups resolve against Extension and return VeChainThor block IDs rather than Keccak hashes, making this an interface fix rather than new capability. Long term impact: proof systems and light-client designs written for Ethereum port across without a VeChainThor-specific rewrite. EIP-7825 - transaction gas limit cap: A hard ceiling of 16,777,216 gas on any single transaction. Human version: No single transaction gets to hog the whole block any more. Queue etiquette, enforced by the protocol. How it changes VeChain: Bounding the worst case holds 10-second block times steady when demand spikes, and it matters more here than on a single-clause chain, because a multi-clause transaction can otherwise stretch across most of a block on its own. Long term impact: predictable block times are what enterprise integrations get procured on, and a bounded worst case is what allows capacity to rise later without the tail risk rising with it. EIP-7934 - block size limit: A ceiling of 8 MiB on the encoded block. Human version: A limit on how fat a block is allowed to get. Keeps running a node in normal-computer territory rather than data-centre territory. How it changes VeChain: Gas accounting alone does not bound how physically large a block can grow, which leaves room to bloat blocks with cheap data and slow propagation across the network, so a byte-level cap closes that gap. Long term impact: node cost stays flat as usage climbs, and node cost determines how widely validation can be distributed. For VeChain, this is the layer that keeps the last two parts honest. Cheaper opcodes and native cryptography don't count for much if block times start slipping or running a node gets too expensive for anyone but a data centre. These three changes are what keep VeChainThor fast, predictable, and decentralised as more builders and more transactions land on it. For enterprise especially, this is the boring but essential part: predictable block times and stable node costs are the structural guarantees that get a network past procurement in the first place. That's the whole of VIP-255, eleven EIPs across three parts. The upgrade goes live at Block Height 25,902,540 on Wed 16 Sep 2026, 11:15:10 UTC (estimated)!

The @quipnetwork attempts to unify a decentralized compute marketplace with a blockchain consensus mechanism grounded in useful work. Hardware operators contribute capacity, the network matches jobs to suitable resources, results are verified, and the same process contributes to chain security and token incentives. This integration seeks to create a feedback loop in which demand for computation supports network security and operator rewards, while the security and incentive structure in turn encourage sustained hardware participation. The hybrid inclusion of classical and quantum resources broadens the potential supply base. Open-source release of the code supports external scrutiny and potential contributions. Challenges inherent in the model include accurate difficulty adjustment for diverse problem types, prevention of low-quality or fraudulent work submissions, reliable market clearing between buyers and sellers of compute, and maintaining economic balance as usage scales. Testnet experience has offered initial operational data; sustained mainnet metrics will be needed to evaluate how effectively the intended alignment of incentives and outputs materializes in practice.

Most projects launch NFTs to raise money. Quip @quipnetwork is doing something different. From their own FAQ: "We like onchain art, and it is the clearest way to show what our randomness can do." Every Quantum Echoes piece is basically a live demo of their QVRF system. First QFT collection seeded by real quantum hardware, and you can actually verify it onchain. Mint details: • September 10 on OpenSea • No mint price • Quip takes zero profit • You only pay gas + the actual cost of generating the quantum seed No fundraising play. Just a real tech demo on Ethereum. That’s rare these days. Provably fair gaming, key generation, oracles… which use case for this randomness do you find most interesting?
