The Ethereum account on X announced a new research report, Alternatives to Concentrated AI, co-authored with Decentralization Research Center (DRC) Head of Research Samuel Vance-Law. It frames AI policy not as a choice between slowing innovation and accelerating at any cost, but as a question of who gets to build, access, and govern these systems.
The report draws on 36 interviews and maps nearly 30 alternatives to concentrated control across the AI stack, spanning chip manufacturing, training, and deployment layers. It includes case studies written by builders at OpenMined, the Ethereum Foundation, and Civic AI.
JPMorgan's JPM Coin (JPMD) USD deposit token is now live on Ethereum, extending from Base to the Ethereum L1, according to an announcement amplified by the Ethereum ecosystem account on X. JPMD gives approved J.P. Morgan institutional clients native onchain cash on Ethereum, alongside the assets and collateral they already transact with.
The Ethereum Foundation's Glamsterdam network upgrade activated on Sepolia at epoch 353,024 — slot 11,296,768 — on October 6, and the official announcement now confirms Hoodi testnet is scheduled for October 26, with a mainnet date to be announced separately. The upgrade's headline feature is blocks built without trusted relays, delivered via enshrined proposer-builder separation (ePBS); following Fusaka, it also adds block-level access lists and gas pricing changes that better reflect execution and state-growth costs.
The Hoodi announcement includes the activation table, client releases, and a bug bounty program.
1791294816, while the EF's Platåberget testnet served as an early public testing ground for the combined Gloas and Amsterdam upgradesHoodi activation is the next milestone ahead of mainnet.
Ethereal published its weekly #41 developer digest, amplified by the Ethereum ecosystem account on X. The leading items were the Glamsterdam upgrade activating on the Sepolia testnet on October 6 and remarks from Vitalik Buterin on the cryptographic world.
Follow-ups and details on the remaining items in the digest were being shared by Ethereal at publication.
The Ethereum Foundation's Trillion Dollar Security initiative is exploring native transaction assertions as a next step to enforce a transaction's final outcome, alongside its Clear Signing work. The initiative identified blind signing and transaction uncertainty as a key user experience risk.
The post examines why a valid signature doesn't always guarantee the outcome a user expects, positioning assertions as a way to make transaction execution conform to what was intended. It reflects an ongoing EF push to reduce UX risk from ambiguous or misread transactions.
The Ethereum Foundation and the Open Anonymity project announced zkAPI, a payment system that lets developers pay for metered APIs — starting with AI inference — without revealing who is paying. It runs on Ethereum Mainnet today.
Users deposit credits (ETH, USDC, etc.) into an onchain vault once; the balance then exists as a private note in a 32-level Merkle tree. Software on the user's device produces a zero-knowledge proof authorizing bounded spend, so the API provider sees requests and the payment layer sees the spend, but neither can link them. Spends use Groth16 on BN254 with Poseidon hashing, nullifiers prevent double-spending, and an onchain escape hatch lets funds be withdrawn even if the servers disappear.
zkAPI implements the "ZK API usage credits" design by Davide Crapis and Vitalik Buterin published on Ethereum Research.
The Ethereum Foundation announced Devcon 8 will take place in Mumbai, India from November 3–6, calling the event the ecosystem's annual physical gathering. For four days, builders, researchers, and community members from around the world developing and deploying Ethereum will meet in one place.
Aave said USDC and USDT deposits from Ethereum are now live in the Aave mobile app. Users on the waitlist can use the shared Ghost Pass code to get in, according to the announcement amplified by the Ethereum ecosystem account on X.
Ethereal published its mini #2 developer digest on September 25, amplified by the Ethereum account on X. The headline items: the Hegotá upgrade's frames-devnet-0 went live under ethPandaOps, Nethermind 2.0.0 shipped, and the Daisugi 0.1 post-quantum testnet launched.
The digest also covered:
Researcher Francesco D'Amato (fradamt) shared a formally verified, machine-checked proof of Ethereum's decoupled consensus protocol — the favored model for 4–8× faster finality — calling it "one step closer" to that target.
The fradamt/verified-consensus repository models decoupled consensus as an executable state machine in Lean 4 and proves its consensus guarantees covering the confirmed, stable, and finalized chains, with no sorry and no project-specific axioms. The results assume honest committee majorities and bounded delivery after GST, among other premises listed in the proof's premise ledger. The Ethereum account amplified the announcement on X.
Nethermind 2.0.0 moves archive-grade history onto the flat state database, cutting full Ethereum mainnet archive storage from ~30 TB to ~2.1 TB and processing blocks up to 2.55× faster on fresh nodes.
The SEC granted temporary, conditional exemptive relief letting Tokenized Securities Venues trade tokenized NMS stocks via permissioned AMM liquidity pools without being classified as exchanges, on the condition tokens carry the same rights as traditional shares.
The Osaka-Fulu ("Fusaka") upgrade, the network's most recent major protocol upgrade, activated December 3, 2025.
GnosisDAO approved moving Gnosis Chain from a standalone L1 into a ZK-proven Ethereum Economic Zone rollup.
The Prague-Electra ("Pectra") upgrade activated May 7, 2025, increasing the maximum validator balance and improving staking and account abstraction.
The Cancun-Deneb ("Dencun") upgrade activated March 13, 2024, adding proto-danksharding (EIP-4844) to dramatically reduce data costs for Layer 2 rollups.
The Shanghai-Capella ("Shapella") upgrade activated April 12, 2023, enabling withdrawals of staked ETH from the Beacon Chain for the first time.
The Merge joined the execution layer with the Beacon Chain on September 15, 2022, permanently replacing proof-of-work and cutting the network's energy consumption by roughly 99.95%.
The London hard fork, activated August 5, 2021, introduced EIP-1559, changing transaction fee mechanics and beginning to burn a portion of ETH fees.
The Beacon Chain, Ethereum's proof-of-stake consensus layer, went live on December 1, 2020, running in parallel with the proof-of-work mainnet and enabling ETH staking as the foundation for The Merge.
Ethereum executed a hard fork at block 1,920,000 that reversed the DAO theft; the minority chain refused the change and continued as Ethereum Classic, a landmark governance split.
An attacker exploited a reentrancy vulnerability in The DAO's smart contract, draining roughly 3.6 million ETH — about a third of the 11.5 million ETH the organization had raised, worth an estimated $50–70 million at the time.
At block 1,150,000 on March 14, 2016, Ethereum executed Homestead, its first planned (production) hard fork, marking the platform's first production release.
Ethereum produced its genesis block on July 30, 2015, launching the Frontier mainnet. The network has run continuously since that date.
Ethereum's public crowdsale ran from July 22 to September 2, 2014, selling more than 60 million ETH for about $18.3 million in bitcoin to fund development.
