Odaily Odaily News: Curated Exchange was officially launched on May 29, 2026. The project was initiated by open-source developers and research scholars. Its underlying theory is based on the academic paper "Decentralized Market Formation" published on SSRN in May this year. The core proposition is to establish a more effective mechanism for discovering, screening, and selecting long-tail assets through a low-cost multi-exchange parallel structure.Any individual, community, or institution can deploy a dedicated vertical trading portal with zero barriers, screen assets, and earn fees. All Venues share the same underlying liquidity. Different from the centralized coin-listing decisions of CEXs and the non-screening mechanism of AMMs, DMF replaces capital access with cognitive access—Curators act as asset gatekeepers based on professional judgment rather than capital scale, ensuring that high-quality long-tail assets are systematically discovered through Curators with reputational constraints.Curated positions itself as a neutral infrastructure provider, avoiding commercial competition with ecosystem participants, and will fully open-source its code in the future. The testnet will be officially launched in June 2026.

Bloomberg Senior ETF Analyst Eric Balchunas posted on X platform, pointing out that Bitcoin's volatility and correlation are increasingly approaching the level of gold. This trend has been significantly underestimated during the current market adjustment and may be a positive signal amid recent market turbulence. Based on the 60-day historical volatility comparison data of IBIT and the gold ETF (GLD) since their launch, Bitcoin's volatility structure is gradually converging with gold, indicating that its asset characteristics may be changing.Eric Balchunas added that despite the volatile market environment, the BlackRock Bitcoin Spot ETF (IBIT) has continued to outperform U.S. stocks since the escalation of the Iran conflict and has achieved more than double the excess returns compared to the S&P 500 ETF (SPY) since the approval of BlackRock's ETFs.

The specifications have been published under an open-source license at otl.network, and the alliance is also open to additional institutional participation.

According to CoinDesk, prediction market platform Kalshi has filed a federal lawsuit challenging a new Minnesota law set to take effect on August 1 that criminalizes operating, hosting, or promoting prediction market platforms. Kalshi argues the law is unconstitutional, asserting it infringes upon the Commodity Exchange Act’s grant of exclusive federal jurisdiction over derivatives markets to the CFTC and violates the First Amendment by restricting advertising. Earlier, on May 19, the CFTC filed a motion making the same constitutional challenge against the state law. U.S. President Trump has also publicly voiced support for the CFTC’s sole regulatory authority over prediction markets. Kalshi previously secured preliminary injunctions in similar enforcement actions brought by New Jersey and Arizona.

According to The Block, Base—the Ethereum Layer 2 network operated by Coinbase—has officially activated the Azul upgrade on its mainnet. This marks Base’s first independent network upgrade following its separation from the Optimism Superchain. The Azul upgrade introduces a multi-proof system that combines TEE (Trusted Execution Environment) proofs with zero-knowledge (ZK) proofs, reducing the shortest possible withdrawal finalization time to just one day. Both proof types can independently confirm proposals; in case of conflict, permissionless ZK proofs override TEE proofs—further enhancing the network’s censorship resistance. Additionally, Azul integrates Base into a single execution client, <code>base-reth-node</code>, and introduces a new consensus client, <code>base-consensus</code>, built on OP Kona. Following the upgrade, the number of empty blocks has plummeted from approximately 200 per day to roughly 2 per day, and the network has achieved a sustained peak throughput of 5,000 transactions per second.
