BlackRock said Bitcoin’s role in portfolios is evolving, positioning it as a complementary diversifier for long-term strategies.

Ripple said it has received preliminary approval for a Crypto Asset Service Provider (CASP) license in Luxembourg under the EU’s Markets in Crypto-Assets (MiCA) framework.

Tesfaye says institutions are prioritizing operational requirements such as reliability, settlement and integration over token issuance.

Japan's lower house has passed a bill that would place cryptocurrencies under a stock-style regulatory framework, with the measure expected to be implemented next year if approved by the upper house. The proposal could treat assets such as Bitcoin and Ethereum as financial instruments, tighten trading rules, and potentially reduce the maximum tax rate on crypto gains from 55% toward about 20%. It may also support the launch of regulated products such as spot crypto ETFs.

On May 29, 2026, Shielded Labs security researcher Taylor Hornby identified a critical flaw in Zcash’s Orchard shielded pool, one day after Anthropic released Opus 4.8.
