TSMC's 2nm Node: Density King, But High Price May Be a Problem

TSMC unveiled its 2nm platform technology at IEDM 2024, featuring energy-efficient nanosheet transistors and 3DIC co-optimization. The process boasts a 30% power improvement and 15% performance gain over its 3nm node, and is projected to be the densest in the 2nm class. However, analysis suggests that while early yield is impressive, a reported $30,000 per wafer price could hamper competitiveness, potentially opening the door for Intel and Samsung to gain market share. TSMC's 2nm node is expected to enter production in the second half of this year.

Mars Dichotomy Boundary Eroded Hundreds of Kilometers

Mars Dichotomy Boundary Eroded Hundreds of Kilometers

New research suggests Mars' iconic dichotomy boundary, separating the higher southern hemisphere from the lower northern one, may have receded hundreds of kilometers due to water erosion. Researchers analyzed data from the Mars Express and Mars Reconnaissance Orbiter, finding that thousands of buttes and mesas near Mawrth Vallis, situated at the dichotomy boundary, share a similar height with a nearby higher-elevation plateau, indicating they are remnants of a larger plateau eroded away. This massive erosion suggests an active water cycle early in Mars' history, consistent with the theory of a northern ocean but also potentially caused by other hydrological processes like ice cap melting. The finding offers new clues about early Martian climate and geological evolution, adding to evidence for a past ocean but also raising new questions.

Basel Tax Authority Buys Bahamian Web Address Due to Flyer Error

The Basel-Stadt tax authority had to purchase a web address in the Bahamas due to a mistake on an information flyer for digital tax returns. The flyer, sent to over 100,000 households, omitted the '.ch' from the web address, redirecting users to a '.bs' domain in the Bahamas. While the error has been addressed and the Bahamian address will redirect to the correct Swiss site, the mistake cost the authority CHF 900, significantly cheaper than the estimated CHF 100,000 to reprint the flyers. Taxpayers can still file their returns online, albeit with a brief Caribbean detour.

Clean: An Embedded DSL and Formal Verification Framework for ZK Circuits in Lean4

2025-03-27

Researchers have developed Clean, an embedded domain-specific language (DSL) and formal verification framework in Lean4 for building zero-knowledge (ZK) circuits. ZK circuits are prone to bugs, and Clean aims to improve correctness by allowing users to define circuits in Lean4, specify their desired properties, and formally prove them. This project is part of the zkEVM Formal Verification Project, aiming to provide infrastructure and tooling for formal verification of zkEVMs. Clean supports four basic operations for defining circuits: witness, assert, lookup, and subcircuit, and offers a monadic interface for enhanced usability. At its core is the FormalCircuit structure, which tightly packages—in a dependently-typed way—the circuit definition, assumptions, specification, soundness, and completeness proofs. Large circuits can be formally verified by recursively replacing subcircuit constraints with their (formally verified) specifications. The framework has successfully verified simple circuits like 8-bit addition, with future plans to add more low-level gadgets, define common hash function circuits, and build a formally verified minimal VM for a subset of RISC-V.
