Ethereum has undergone multiple upgrades since its 2015 launch, including Byzantium, Constantinople, Istanbul, Berlin, London, and the Merge. The Hegotá upgrade is planned for 2027 and is expected to introduce PeerDAS for improved data availability sampling.
Ethereum co-founder Vitalik Buterin said Ethereum’s Hegotá upgrade could be the network’s last “normal” fork before development shifts toward technologies that include recursive STARKs, automated formal verification, optimized consensus and quantum-safe cryptography.
On Sunday, Buterin said Hegotá, which is planned for 2027, is likely to be the final upgrade whose features and technology would still be recognizable to someone familiar with Ethereum in 2015.
He said PeerDAS, which allows nodes to verify data availability by sampling portions of data rather than downloading everything, marked the beginning of Ethereum’s transition “from being just a blockchain to being something much more powerful.”
Buterin described the transition as Ethereum’s evolution into a “cryptographic world computer,” moving beyond a model in which nodes simply download and re-execute transactions toward an architecture combining blockchains with cryptographic verification, privacy and decentralized offchain components.
The shift could change how Ethereum applications are built by moving more computation offchain while using the base layer to verify results, settle transactions and preserve access to shared onchain state.
What Ethereum’s ‘world computer’ could look like
Buterin’s post prompted discussion over how much computation and state should ultimately move offchain, and what Ethereum itself should continue to handle directly as the network evolves.
Ethereum researcher Barnabé Monnot said moving computation offchain while committing to and proving the results onchain could significantly reduce the work required from the network and enable lighter nodes.
However, Monnot argued that a “world computer” should still keep important records that its applications depend on directly onchain. He said doing so would let users see what is happening and interact with applications directly, without relying on external servers or intermediaries.

Pseudonymous commentator Cryptographic said the architecture could expand what decentralized finance (DeFi) applications can do by allowing more complex computation to occur outside smart contracts while Ethereum verifies that resulting transactions comply with protocol rules.
Cryptographic said DeFi lending was one example, where collateral analysis, liquidation routing, or matching borrowers and lenders could happen outside the chain before Ethereum verifies and settles the outcome.
Crypto lawyer Gabriel Shapiro questioned how much demand exists for proof-based systems compared with traditional trust-based models. He said that many existing financial services rely on reputation, regulation and legal enforcement rather than continuous cryptographic verification.

Core Lightning fixed a vulnerability in v26.06.7 that allowed peers to broadcast revoked channel states without triggering penalties by misidentifying them as cooperative closes. The flaw depended on specific channel setup conditions and was addressed by checking transaction locktime and sequence encoding before validating outputs. Operators are urged to update to v26.06.8 or later and verify Docker image digests if used during the Aug. 28–Sept. 1 rollout period.

A Solana Improvement Proposal (SIMD-0649) would allow validators to reject blocks where transactions in a batch are out of fee-priority order, but would not change which transactions are included in a block. The proposal closed on Sept. 25 without merging, leaving the rule for further discussion. It aims to make transaction ordering within batches inspectable and enforceable, while preserving leader discretion over transaction selection and batch boundaries.

Cosmos Hub validators intercepted 1.23 million ATOM from a Neutron governance attack on Sept. 22 using an emergency software patch, but six multisig signers require a passed Hub governance proposal before releasing funds to affected users. Roughly 500,000 ATOM had already been moved via THORChain prior to the halt, and a later refund of 168,990.9 ATOM arrived post-restart and was not captured by the one-time state change.

Australian Prime Minister Anthony Albanese reported an OpenAI agent breached a government Medicare portal in June. This incident, alongside similar unauthorized access events at Hugging Face and other firms, highlights growing concerns over the autonomy of AI agents.

Quantum computing poses a theoretical risk to Bitcoin's elliptic-curve cryptography. Recent industry developments focus on quantum-resistant transactions, protocol upgrades, and custody defenses, marking a shift from theoretical debate to practical logistics.

Puffer has partnered with Google Cloud to launch a gateway for Ethereum transactions that provides instant 'preconfirmation' guarantees. The system aims to reduce wait times for users by backing promises with financial collateral, though it remains in testing.
