Bitcoin Faces Quantum Risk — New Proposal Could Lock Vulnerable Coins

A new Bitcoin security proposal, BIP-361, introduces a three-phase plan to protect the network from the future threat of quantum computers. It specifically addresses the vulnerability of approximately 1.7 million BTC, including Satoshi Nakamoto's fortune, held in old-style P2PK addresses whose public keys are exposed. The proposal would eventually freeze any coins not moved to a new quantum-resistant format after a multi-year grace period. A controversial "rescue window" would allow users who miss the deadline to reclaim funds by proving ownership of their seed phrase. The plan has faced significant community backlash, with critics labeling it authoritarian and confiscatory for rendering old Bitcoin unspendable. Its adoption depends on achieving network consensus.

Tsinghua's Prediction 2 Years Ago Is Becoming Global Consensus: Meta and Two Other Major AI Institutions Have Reached the Same Conclusion

Summary: In a remarkable validation of Chinese AI research, Meta and METR have independently reached conclusions that align perfectly with the "Density Law" proposed by a Tsinghua University and FaceWall Intelligent team two years ago. Published in Nature Machine Intelligence in late 2025, the law states that the computational power required to achieve a specific level of AI performance halves every 3.5 months. This convergence was starkly evident in April 2026. METR reported that AI capabilities are doubling every 88.6 days, while Meta's new model, Muse Spark, demonstrated it could match the performance of a model from the previous year using less than one-tenth of the training compute. When plotted, the growth curves from all three sources—using different metrics (parameters, compute, task length)—show an almost identical exponential slope. The findings have profound implications: AI inference costs are collapsing faster than anticipated, powerful edge-computing AI is becoming rapidly feasible, and the industry's strategy of simply scaling model size is becoming economically inefficient. The Chinese team, which has been building its "MiniCPM" model series based on this law since 2024, is seen as having a significant two-year lead in practical engineering experience, marking a rare instance where Chinese researchers pioneered a fundamental predictive trend in AI.

A Detailed Explanation of Tempo Chain and MPP Machine Payments Protocol

The global payment system is undergoing structural transformation, driven by the explosive growth of stablecoins and the rise of the AI agent economy. This creates a pressing need for next-generation payment infrastructure. AI agents have five core payment requirements: autonomy, micro-payments, high frequency, interoperability, and atomic settlement. Tempo, a payment-native blockchain by Commonware, addresses these needs. It features the Simplex BFT pipelined consensus for sub-second finality, dedicated block space, a stablecoin-native gas mechanism, and the Machine Payments Protocol (MPP) for end-to-end autonomous payments. Its technical architecture is payment-optimized. Key innovations include: - **Simplex BFT Consensus:** A pipelined design reducing confirmation latency to one network round-trip (1Δ). - **BLS Aggregate Signatures:** Minimizes bandwidth and computational overhead. - **Parallel Transaction Execution:** Enabled by custom EIP-2718 transaction types and an expiring nonce system. - **Dedicated Payment Lanes:** Protocol-reserved block space to shield payments from network congestion. - **Stablecoin-Native Design:** Stablecoins are first-class citizens for gas and on-chain exchange. MPP, co-designed with Stripe, is an open standard like "OAuth for payments." It enables AI agents to pay autonomously via a standardized HTTP challenge-response flow. Its core innovation is a session mechanism for efficient, continuous resource consumption without per-action on-chain confirmations. MPP is payment-rail agnostic, supporting various networks like Tempo, Stripe, and Lightning. Application scenarios include cross-border corporate settlements, 24/7 tokenized deposit clearing, commercially viable micro-payments, and autonomous AI agent transactions. Compared to rivals like Circle's Arc and Stable, Tempo differentiates through its EVM compatibility and Stripe partnership. Versus general-purpose chains like Ethereum L2s and Solana, Tempo's advantage lies in its payment-semantic native design, not just superior performance. The success of autonomous AI payments hinges on resolving regulatory uncertainty around agent identity and compliance. Tempo's core contribution is rethinking payment infrastructure at the protocol level, focusing on precision in payment semantics, pluggable compliance, and agent authorization models.

Grayscale Highlights Bitcoin’s Resilience as Community Prepares for Quantum Era

Grayscale's head of research, Zach Pandl, argues that Bitcoin's primary challenge in the quantum era is not technological but social. While a recent Google study raised concerns about quantum computers potentially breaking Bitcoin's encryption, Pandl highlights that Bitcoin's UTXO model, proof-of-work consensus, and lack of native smart contracts make it less vulnerable than other cryptocurrencies. The real issue lies in the community's ability to reach consensus on how to handle the estimated 1.7 million BTC in early, quantum-vulnerable addresses—including those possibly belonging to Satoshi Nakamoto. Potential solutions include burning those coins, limiting spending from risky addresses, or taking no action. This echoes past divisive debates, like the one surrounding Bitcoin Ordinals, underscoring the difficulty of achieving community agreement.

Ethereum Unveils Post-Quantum Security Roadmap For Institutions

Ethereum has publicly formalized its post-quantum security roadmap, targeting a critical threat to its cryptographic foundations. Presented at the Institutional Ethereum Forum, researcher Will Corcoran outlined the risks quantum computers pose to elliptic-curve cryptography, which secures validator attestations, transactions, and wallet signatures. The core challenge is not just replacing signatures but managing the trade-offs: the proposed hash-based scheme, LeanSig, is significantly larger than current BLS signatures, threatening bandwidth and decentralization if naively implemented. Ethereum's solution pairs LeanSig with a STARK-based aggregation engine called Lean Multisig to compress signature data, making it viable. With a cryptographically relevant quantum computer estimated by 2032, Ethereum is targeting key upgrades for its 2029 hard fork. The effort, involving extensive research and testing, is positioned to set a new industry standard for all proof-of-stake blockchains facing this unavoidable scaling problem.

Is XRP More Sustainable Than Bitcoin? Energy Consumption Difference Sparks Debate

A new report from Bullrunners has reignited the debate between Bitcoin and XRP, focusing on their vastly different energy consumption. The analysis claims that XRP’s entire network consumed only $73,000 worth of electricity in a year, while Bitcoin used over $10 billion during the same period. A single Bitcoin transaction consumes between 1,100 and 1,400 kWh—enough to power an average U.S. household for 38 to 49 days. In contrast, an XRP transaction uses just 0.0079 kWh, comparable to powering a light bulb for a few seconds. The report concludes that XRP uses 99.999% less energy than Bitcoin. This disparity stems from their consensus mechanisms: Bitcoin relies on energy-intensive Proof of Work (PoW) mining, while XRP uses the XRP Ledger Protocol Consensus, where trusted nodes validate transactions without mining. The findings sparked intense community reactions. Bitcoin supporters argue its energy use is essential for security and decentralization, while XRP advocates highlight its superior energy efficiency compared to both Bitcoin and Ethereum, even after Ethereum’s switch to Proof of Stake (PoS).

Ripple CTO Emeritus Fires Back at XRP Ledger Centralization Claims

David Schwartz, Ripple's CTO Emeritus, refuted claims by Justin Bons, founder of Cyber Capital, that the XRP Ledger (XRPL) is centralized due to its Unique Node List (UNL) structure. Bons argued that the UNL grants Ripple "absolute power and control," making validators permissioned. Schwartz countered that the UNL does not enable censorship or double-spending, as validators cannot force dishonest actions on individual nodes. He explained that a malicious validator would simply be ignored by honest nodes, comparing a potential attack to a chain halt rather than a security breach. Schwartz emphasized that XRPL was intentionally designed to limit Ripple's control, even under legal pressure, and that abusing power would destroy trust in the network. He also contrasted XRPL's record with Bitcoin and Ethereum, claiming no history of transaction censorship or malicious re-ordering on XRPL.
