A zero-knowledge proof lets one party prove to another that a statement is true without revealing any information beyond the truth of the statement itself. It is the cryptographic technique behind blockchain privacy, scalable rollups, and a growing number of identity verification systems. The standard explanation of zero-knowledge proofs uses the cave analogy. Ali Baba knows the secret word to open a door inside a circular cave. He can prove he knows the word by entering from one side and exiting from the other, on demand, without ever saying the word out loud. After enough successful demonstrations, the verifier becomes…

$ENS Labs has revised a governance proposal after delegate criticism over treasury control, choosing to keep the DAO’s primary operational wallet custody in place rather than moving broader control to the Foundation. According to the validated notes, the revised plan scraps the more contentious transfer of the DAO’s operational wallet, which includes ETH and stablecoins. The DAO retains custody, while only the $65 million Endowment Safe is set to transition to the Foundation, subject to a timelock and Security Council cancellation rights. The DAO’s 54.6 million $ENS tokens remain with tokenholders, while the Foundation would receive a 1 million $ENS…

Senate negotiators on the CLARITY Act have run into a condition several Democrats are treating as essential: they want ethics language limiting how much senior officials, including the president and vice president, can profit from digital asset ventures. That condition traces back to a warning crypto figures made before the 2024 election, when they argued that tying the industry too closely to a political figure could turn market structure legislation into a partisan fight. The CLARITY Act, the market structure bill the industry has wanted for years, is now testing whether that warning held up. Republicans added ethics restrictions to…

Corporate blockchains are multiplying, but Coinbase CEO Brian Armstrong expects the boom to end in consolidation rather than coexistence. Over the past year, several corporate institutions and Wall Street giants, including Stripe, Circle, and Robinhood, have developed rails for stablecoins and institutional markets. Their expansion has revived concern that regulated companies with established distribution could draw financial activity away from the permissionless networks that powered crypto’s growth. However, Armstrong views the proliferation differently, as he expects the new launches to fragment liquidity and users before network effects force weaker platforms to combine or retreat. Corporate chains are already finding users…

Iran’s foreign minister said negotiations with the US will begin the same day both countries sign a memorandum of understanding, with a 60-day window afterward to resolve the nuclear issue and secure sanctions relief. Bitcoin reacted to the framework itself, a memorandum signed before any of its harder terms were settled. Brent crude fell about 5% to $78.96, and WTI settled at $76.05, both near three-month lows, as traders priced in the reopening of the Strait of Hormuz and renewed Iranian oil exports. The Strait of Hormuz carried about 20% of global oil and petroleum product consumption and more than…

After several days of high activity, on-chain data indicates that Shiba Inu’s exchange flow dynamics have changed once more, with netflows returning to almost neutral territory. After last week’s dramatic fluctuations, the most recent metrics show a net exchange flow of roughly -2.31 billion $SHIB over the previous 24 hours, indicating that inflows and outflows are now mostly balanced.

“We are going to see a lot more of these closures announcements. I think the only exchanges that will survive are those not dependent on retail trading to be successful. In the short term, I don’t see a return for retail trading in the numbers we used to see in 2021.” Trading volume falling Crypto’s centralized exchanges are experiencing their quietest stretch in over two years., Spot trading volume across major centralized venues fell to $1.05 trillion by April 2026, its lowest monthly total in 25 months, according to the CoinDesk Data Exchange Review. For context, that represents a steep…
