Ethresear.ch: split payloads cut 1 MiB broadcast from 4.9s to 0.73s
Csaba Kiraly posted on Ethresear.ch on September 4, 2026, arguing that whole-payload gossip works today because datacenter builders carry it, not because the protocol is ready for roadmap sizes. In the least favourable setting tested, a 1 MiB payload from a home builder with no datacenter nodes, the segmented design reduced median receiver completion from 4.9 seconds to 0.73 seconds and cut copies received from 4.4 to 1.4. The post would add a bid commitment field at Gloas or Hegota and activate the networking-only rules at Hegota. Payload-due remains half the slot, which is 6 seconds on today's 12-second slots.
ERC-8410 drafts a digest-bound execution plan for keyless wallets
Moody Salem opened GitHub pull request 1992 on September 4, 2026, adding draft ERC-8410, a JSON execution plan that carries an ordered call sequence from software with no keys to the wallet that signs. The plan digest is keccak256 over exactly the broadcast-determining fields, so a later calldata change breaks the digest, while gas hints and extension bags stay outside it. Magicians thread 29587 is the discussions-to link. The PR ships four digest test vectors, including one cross-checked between independent Rust and JavaScript implementations.
Kraken opens USDT0 deposits and withdrawals on Stellar
Kraken said on September 4, 2026, that USDT0 deposits and withdrawals on Stellar are live, with settlement in roughly five seconds and typical network fees of a fraction of a cent. USDT0 is described as an omnichain version of Tether USDT using LayerZero's OFT standard: USDT is locked on Ethereum and an equivalent amount of USDT0 is minted on the destination chain, redeemable 1:1. Trading in the Kraken App and Instant Buy waits until enough buyers and sellers are present. Geographic restrictions may apply, and deposits sent on unsupported networks can be lost.
Kraken pauses deposits on 23 Cosmos-family networks
Kraken's status page, updated 21:43 UTC on September 4, 2026, said deposits are temporarily paused and withdrawals may be delayed or unavailable on Akash, Babylon, Celestia, Cosmos Hub, Coreum, dYdX, Dymension, Fetch.ai, Initia, Injective, Juno, Kava, MANTRA, Neutron, Nym, Osmosis, Saga, Secret Network, Sei EVM, Stride, Terra, Terra Classic, and THORChain. That is a 23-network list spanning Cosmos-family chains plus THORChain. The incident was still identified, not resolved, in that update. Kraken said it is working to restore funding services safely.

The Arbitrum OpCo posted its August 2026 update on September 4. It said Coinflip, a former GMX core contributor and Arbitrum delegate, was formally hired as Head of OpCo, after which the Oversight and Transparency Committee will step back from driving hiring. Second-term OAT elections reelected A.J. Warner and Patrick McCorry, elected Pedro Breuer, reappointed Gavin Wang, and appointed Traver Normandi in place of Tyler Bench. On the Arbitrum Gaming Ventures wind-down, OpCo said it returned 43 million ARB to the DAO treasury and 7 million USDC to the ATMC in July.
