Base, the Coinbase-backed Ethereum layer-two network, plans to activate its Beryl upgrade on mainnet on June 25, 2026, at 18:00 UTC. The release introduces B20, a native token standard built into node software rather than deployed as a smart contract. Base engineers say B20 is designed as a superset of ERC-20 so tokens remain compatible with existing wallets, exchanges and decentralized applications.

Algorand says it is working to become quantum-resistant by the end of 2027. The proof-of-stake blockchain plans to do so by advancing post-quantum cryptography, including post-quantum multisignatures as a policy layer. The goal is to maintain protection against both classical threats and risks expected in a quantum era.

Kalshi has begun informal discussions with investment banks about a potential initial public offering, according to a report from The Information published this week. The report said the talks are still at an early stage. There has been no S-1 filing, no banker selected and no public timeline.

A Japanese corporate pension fund for small and mid-size businesses plans to allocate 1% of its assets to cryptocurrencies in fiscal 2026. The fund manages about 21.3 billion yen ($136M) for roughly 1,200 companies. It describes the move as currency diversification rather than a return-driven bet. The exposure will be taken through a passive multi-crypto fund rather than direct token purchases.

As automated trading systems spread across DeFi, security risks are increasingly shifting beyond smart contracts. Operational security—especially around workflows and permissions—is emerging as a growing challenge alongside code-level vulnerabilities.

The Ethereum Foundation has proposed “clear signing” standards aimed at replacing blind signing and making wallet approvals easier to understand. The guidelines would present Web3 transactions in human-readable summaries rather than raw hexadecimal data. The goal is to reduce the risk of phishing scams that trick users into authorizing malicious transactions.

“Q-Day” refers to the point at which a sufficiently powerful quantum computer could break the cryptography that protects crypto wallets. Algorand published a post-quantum roadmap on June 18 and said it is aiming for full quantum resilience by the end of 2027. The plan includes early milestones in 2026, including post-quantum accounts and multisig support.

Microsoft warned of malware that spreads via USB flash drives by using Windows shortcut files to infect devices. The so-called “clipper” malware looks for cryptocurrency addresses copied to a user’s clipboard and replaces them with attacker-controlled addresses. The alert came from the Microsoft Defender team, Windows’ built-in security tool.
