ePBS changes the block-building auction on Ethereum by letting proposers delay selection of the winning bid and choose which signed bids to disclose, and a game-theoretic model predicts lower proposer revenue and lower allocation efficiency in parts of the parameter space, according to a paper by Jingyu Liu, Bolin Zhang, Lin William Cong, Siguang Li ...
dexamine is a Python package built to turn Uniswap event data stored in Ethereum transaction receipts into records of trades and liquidity changes. The library covers Uniswap v2 and v3 swaps, mints, and burns on Ethereum mainnet, and it attaches token quantities, pool state, transaction position, and gas fields to every event. Version 1.1.0 installs ...
A new Monero eclipse attack isolates unreachable nodes running behind a firewall or Network Address Translation (NAT), a group long considered safer than nodes with public IP addresses. Research accepted at the ACM Conference on Computer and Communications Security (CCS) 2026 shows an attacker can take over all 12 outgoing connections of a NAT-protected node ...
Crypto prediction markets reached a new stage on October 9, 2026, when Decrypt, citing CNBC, reported Blockchain.com’s applications to the Commodity Futures Trading Commission (CFTC) for a designated contract market (DCM) license and a futures commission merchant (FCM) registration. Blockchain.com has offered event contracts to international customers through a Polymarket partnership since early 2026, and ...
Binance hacks span four security incidents between 2018 and 2026, and the most recent one, detected on October 29, 2026, moved approximately $6.3 billion out of Binance hot wallets on several blockchains. The exchange suspended withdrawals, committed its SAFU fund and company reserves to cover losses, and opened an investigation with law enforcement. Chainalysis and ...
Blockchain attack detection gains broader coverage from a signal most detectors ignore: function names. TxLucent, a detector from the University of British Columbia, converts transaction call traces into function name sequences and classifies them with a Transformer, reaching a 1.56% false negative rate on 424 real incidents and a 0.0017% false positive rate on 537 ...
DeFi decentralization moves along four dimensions at different speeds, and Aave protocol records show the split: mean weekly active position-holder addresses rose 91.0% around GHO stablecoin issuance on Ethereum, but only 1.7% around the token’s expansion to Arbitrum, where activity concentration climbed 58.1% while Ethereum concentration fell 31.5%. The comparison covers 1,956,216 Pool events and ...
Ethereum Gas Fees Peak at Hour 12 UTC in a Seven-Firm Dataset Ethereum gas fees follow an intraday pattern, and the pattern raises costs for operational firms with fixed transaction deadlines. An analysis of 62,142 confirmed Ethereum transactions from seven companies, collected between January and March 2026, places the cost peak at hour 12 UTC ...
NFT market correlations among Ethereum collections are weaker than correlations in cryptocurrency, stock and Forex markets, and they deviate from pure noise, according to a study by Marcin Wątorek, Paweł Szydło, Jarosław Kwapień and Stanisław Drożdż, posted in April 2024. The authors apply random matrix theory, detrended cross-correlation coefficients and minimal spanning trees to 90 ...
Loss-versus-rebalancing (LVR) costs a representative Ethereum liquidity position 471 basis points per year at Ethereum’s 12-second slot, and a jump-diffusion model of the reference price shows 125 basis points of the loss persist at any block speed. The result challenges the standard case for shorter blocks, which argues faster block production shrinks arbitrage profits against ...
