The U.S. Securities and Exchange Commission (SEC) has approved a Nasdaq rule change that allows certain securities to be traded in tokenized form, a move that integrates blockchain technology into traditional stock market infrastructure.

The approval, issued Wednesday, is part of a broader effort to explore digital representations of regulated assets while maintaining investor protections and market stability.

Under the new framework, eligible securities — including stocks in the Russell 1000 Index and exchange-traded funds (ETFs) tracking major benchmarks such as the S&P 500  — can be represented and traded as tokenized assets on Nasdaq. 

These tokenized versions are fully…

Over 50 years after the first inter-networked message, peer-to-peer networks remain rare beasts in the jungle of the Internet. Bitcoin’s ability to provide an open monetary system depends on its peer-to-peer architecture, and across its attack surface it is the networking layer–how peers discover and connect to each other–that is the most vulnerable. There are two main places problems can occur: Bitcoin’s own peering protocol, and the Internet protocols that Bitcoin’s protocol depends on. In this light Core has a dual mandate to prevent Denial of Service (DOS) vectors that can be abused between nodes, and enable nodes to communicate safely in the wider adversarial environment…

The Federal Reserve on Wednesday kept its benchmark interest rate steady, maintaining the federal funds target range at 3.50% to 3.75%. Bitcoin price is fighting to hold $70,000 amid a complex backdrop of elevated inflation, slowing job growth, and war in the Middle East.

A dispute over more than $172 million in Bitcoin has moved forward in the UK’s High Court of Justice, where a man alleges his estranged wife stole thousands of coins from his hardware wallet using covert surveillance inside their home.

Court filings show that Ping Fai Yuen, a UK resident, held 2,323 Bitcoin in a Trezor hardware wallet in 2023.

Yuen claims his wife, Fun Yung Li, obtained access to the wallet’s recovery phrase, which can be used to…

Vitalik Buterin posted on X (formerly Twitter) praising a detailed explanation of Ethereum’s “dynamically available consensus.” He highlighted its dual benefits: providing strong economic finality and ensuring chain progress continues even when finality cannot be achieved due to network conditions.
In a follow-up post, he stated that once the “Lean Ethereum” initiative is fully deployed, Ethereum will uniquely combine theoretically optimal security under synchrony (requiring 51% honest online validators) with robust economic finality under asynchrony—unlike most fast chains (which prioritize only finality) or Proof-of-Work chains (which prioritize only synchrony security). This positions Ethereum as distinctive among major blockchains.
