Ethereum co-founder Vitalik Buterin outlined a plan to increase network transaction capacity without sacrificing decentralization, combining near-term parallel verification with fee reforms for permanent data. Upcoming upgrades referred to as Glamsterdam and ePBS will let validators examine different parts of a block simultaneously, freeing time within each 12-second slot and enabling more activity without expanding block size or requiring more powerful hardware, Buterin wrote. The plan revises how storage is priced, separating temporary compute from actions that add data every node must store permanently; operations creating long-term storage would carry higher fees, while everyday transactions could become cheaper or remain stable. Long term, the roadmap leans on zero-knowledge proofs and blobs so validators can confirm blocks without re-executing every operation, cutting computational load and boosting capacity while keeping the network open to smaller operators, Buterin said.

WhiteBIT Coin (WBT) is trading around $50.45 after a 21% decline from its December all-time high of $64.11, with the $50 level acting as support across four separate tests, The Crypto Basic reports. The token's market cap stands above $10.8 billion, while WhiteBIT positions itself as a major European exchange with 35 million users in over 150 countries, approximately $3 trillion in annual volume, and recent expansions including a U.S. launch and a partnership with Saudi Arabia's Durrah AlFodah Holding. WBT has a fixed supply of 400 million tokens, circulating supply near 213.7 million, and 81.5 million locked until March 13, alongside a weekly burn program aimed at destroying at least half of total supply and user benefits such as fee discounts and higher staking yields. Technical indicators including MACD, RSI at 57.5, and a Bollinger Band squeeze point to a possible directional move, with $54 and the 50-day moving average as upside levels and $48 as a downside break level, according to the report, which notes the information is not financial advice.

Vitalik Buterin said Ethereum's "Strawmap" aims to cut slot time from 12 seconds to 2 seconds and achieve 6–16-second finality using post-quantum hash-based signatures. Lookonchain data, citing Arkham, show he sold 17,196 ETH ($34.96 million) since the beginning of February, surpassing his January allocation of 16,384 ETH by 4.9%.

Cardano saw liquidity reach $14 million in one hour ahead of the USDC mainnet launch. The activity involved ADA, USDC, and USDCX.
