ChainFeeds Research’s latest PRO edition surveys a wide stretch of crypto protocol work, led by Ethereum’s Hegotá upgrade priorities and a new analysis of Block-Level Access List, or BAL, pricing under EIP-7999. Ethlabs argues Hegotá should stay focused on a small set of issues tied to Ethereum’s long-term competitiveness, placing FOCIL and Quick Slots at the top of the list while also backing native account abstraction through EIP-8141 Frame Transactions and a more careful approach to scaling via resource pricing and propagation improvements rather than simply raising the gas limit. The issue also tracks Bitcoin protocol discussions. It highlights sipa’s proposal for handling larger post-quantum cryptography witness data without introducing another transaction identifier, a disclosed reorg attack risk affecting LND versions before 0.20.0, and a proposal by Jean Pablo to formalize the rawtr() output script descriptor in a BIP. On the research side, Fei Wu uses data from February through May 2026 to argue BAL should be priced as a byproduct of execution and state access instead of as a standalone resource. Other featured work includes Ethereum PoS head-vote timing research, a zero-bridge cross-chain exchange design called BTCP, a roundup from The MEV Letter #150, and a machine-learning paper on early detection of fraudulent memecoins on Solana.

a16z researchers introduce Strong Chain Quality (SCQ), extending chain quality from average over time to per-block space allocation. Holding 3% of total stake ensures 3% blockspace in every block, via virtual lanes. SCQ boosts fairness, censorship resistance, and requires only two extra communication rounds.

GhostSwap, a privacy-focused DEX, goes live on Solana, enabling anonymous cross-chain swaps. Its native token $GHOST surged over 300% before the launch and then dropped 34% in 24 hours, currently trading at $0.005088.

Four crypto projects dominate this weekend: DOGEBALL gaming L2 presale ($90K raised), MemeCore cross-chain bridge, Kaspa Rust upgrade, and Cosmos Interchain Security 2.0.

2026 mining profitability is highly fragmented: Bitcoin is an industrial game, LTC+DOGE merged mining boosts returns, Zcash and Dash offer thin margins, GPU coins like Ergo and Vertcoin suit hobbyists, and Monero remains the go-to CPU option. Power rate is the key variable.

John McAfee has announced the launch of privacy coin GHOST, distributing 25% of supply via airdrop to ESH holders. The snapshot was taken on May 24, causing a surge in ESH demand and price.

John McAfee said he is leaving the Ghost cryptocurrency project, blaming management and warning it will fail. He said the Ghost phone service remains on track, but the ecosystem will replace the current privacy coin with a new token.
