ChainFeeds2026-08-10 10:49:07ChainFeeds PRO reviews Ethereum multi-dimensional gas design, PoS security models, and oracle silenceChainFeeds Research’s PRO issue #154 pulls together several research threads across Bitcoin and Ethereum. The report highlights Fei Wu’s work on Ethereum’s post-Glamsterdam fee market, where EIP-8037 and EIP-7999 would shift gas pricing from a single-meter model to separate pricing for execution, data, and state creation. Using historical gas changes, the study models demand curves for each resource and finds different elasticities: execution is least sensitive to price, data sits in the middle, and state creation is the most sensitive. Under higher block capacity, state creation could become the new fee bottleneck. On Bitcoin, the report covers josh’s HTLC design aimed at removing reliance on mempool-based preimage monitoring and the free-relay assumption, as well as a staletip P2P message proposed by Ram and w0xlt to improve visibility into stale blocks. On Ethereum research, Hudu Yusuf questions whether stake weight truly reflects effective consensus weight and whether continuous oracle output is always safer than silence, proposing DW-BFT and a structured-silence model. The issue also includes Sidistr’s Arcanum, a compiler-layer approach for keeping source code hidden through a TEE-to-ZK roadmap, and a paper from Old Dominion University on what drives contentious Bitcoin soft forks toward orderly upgrades or lasting chain splits.2090
Ostium2026-07-17 05:32:11Ostium hit by oracle report exploit as five-minute incident drains up to $24 millionOnchain perpetuals platform Ostium said a five-minute security incident hit its public Ostium Liquidity Provider, or OLP, vault on July 15 between 14:18 and 14:23 UTC. Third-party security firms said the issue was not a missing signature. Instead, they said a registered PriceUpKeep forwarder submitted authorized oracle reports carrying future timestamps, which then generated false trading profits. Public loss estimates vary. Blockaid put the payout near $18 million, Cyvers estimated $23.7 million, and PeckShield later said about $24 million had been drained. SlowMist cited a lower figure of $11.86 million, apparently based on a visible vault outflow of 11,862,444.782 USDC in a referenced transaction. Ostium co-founder Kaledora Kiernan-Linn said the team detected the issue within minutes and coordinated a trading pause within an hour. She also said the protocol is working with law enforcement, SEAL 911, and outside security experts. Ostium has not yet published a final loss total, root-cause analysis, or post-mortem report. The case differs from Bonzo Lend’s recent Hedera incident, where the validator reportedly accepted a proof without a valid signature. In Ostium’s case, security firms said authentication passed, but the data itself was unsafe.1460
DeFi2026-07-10 09:13:13DeFi Protocols Turn to Chainlink After Kelp DAO Attack Sparks Oracle Security ReviewFollowing the $293 million Kelp DAO attack, DeFi protocols are reassessing oracle and cross-chain infrastructure. Solv Protocol and Tydro have moved toward Chainlink, while broader concerns grow over security, data accuracy, and concentration risk.1820
