Nvidia is facing a shareholder class action alleging it failed to properly disclose how much gaming GPU revenue was driven by Ethereum mining demand during fiscal 2018. The U.S. Supreme Court is reviewing a 9th Circuit decision that let the case move forward, with the investor class spanning Aug. 10, 2017 to Nov. 15, 2018. The dispute follows a May 2022 SEC settlement in which Nvidia paid $5.5 million over disclosure issues tied to fiscal Q2 and Q3 2018.

The Ethereum Foundation has introduced its 2029 “Strawmap,” a seven–hard fork plan designed to move the network to post-quantum cryptography while also cutting block finality to under 16 seconds. The sequence is set to begin in 2026 with the Glamsterdam fork in the first half of the year, followed by Hegota later in 2026, as Ethereum works toward STARK-based signatures and Single Slot Finality.

South Korean lawmakers from the ruling People Power Party and the opposition Democratic Party agreed to postpone a planned 20% tax on virtual-asset gains until 2027 after estimates showed $110 billion in annual outflows. Regulators said outflows accelerated in H2 2025, including $60 billion leaving in six months, as traders shifted activity to offshore venues offering futures, leverage and hedging tools not available domestically.

The CFTC authorized a dedicated Innovation Task Force on Tuesday to update its regulatory approach for crypto assets, artificial intelligence, and prediction markets. The effort, led by senior adviser Michael Passalacqua, is positioned as a shift from enforcement-led oversight toward clearer compliance pathways for decentralized protocols. Michael Selig later said on March 12, 2026 that U.S. markets must prevent manipulation and fraud to avoid another FTX-like collapse.

Bittensor's TAO token economy is being valued against about $52 million in annualized emissions subsidies rather than organic revenue, while subnets are priced at roughly $1.37 billion. After the December 2025 halving cut daily emissions from 7,200 to 3,600 TAO, the model faces a tighter runway if external revenue does not scale. The protocol currently directs about 518 TAO per day to top subnets such as Chutes, leaving validator yield heavily tied to inflationary rewards.

Balancer Labs is winding down after a $128 million exploit on November 3, 2025, with co-founder Fernando Martinelli saying the Balancer protocol will continue under a decentralized structure. The incident was tied to a rounding flaw in V2 swap logic across six blockchains, and governance is now weighing a leaner "OpCo" model with changes to emissions and incentives.

EDXM International says it will roll out a blockchain-based Korean won perpetual futures contract in April 2026, designed to track KRW/USD via a synthetic KRWQ/USDC pair. The product settles in USDC and uses an offshore won-backed stablecoin structure positioned as an alternative to traditional KRW non-deliverable forwards, a market cited at roughly $27 billion in average daily volume.

Tether has taken a strategic stake in AI sleep-tech firm Eight Sleep at a $1.5 billion post-money valuation, positioning the deal as more than a passive investment. The move draws on Tether's reported 2024 profit of over $13 billion and its $6.3 billion in excess reserves, which it has been deploying across multiple venture divisions.

Circle has submitted a request to the European Commission asking it to lower the market-cap thresholds in the EU's proposed Market Integration Package, arguing the current design blocks euro stablecoins from scaling. The company says euro-denominated e-money tokens such as EURC cannot be used for institutional settlement under the draft Central Securities Depositories Regulation unless they are already large. Circle's submission was dated March 20, and it frames the thresholds as a barrier to entry for on-chain securities settlement in Europe.
