The long-awaited @VitalikButerin speech “The Next 5 Years of Ethereum Core Tech” at #EDCON2025 is finally out ! Big thanks to @francescoswiss for the quick summary https://t.co/C6wo7d1vIE The talk has already sparked great discussions ! Watch the full recording and check out

1/ Fusaka is coming December 3rd. Ethereum’s next major upgrade shows that the network can grow to meet global demand, without compromising on decentralization or permissionlessness. Whether you’re a user, builder, institution, or operator, here’s how Fusaka will impact you.

In 2000, the S&P 500 had an elevated trailing P/E of 26, well above its long-term avg. of 14. For the next 11 years, the S&P 500 delivered zero returns! The current S&P 500 trailing P/E is 30 – even higher than 2000. History rhymes. For standardized performance visit our website.

The quantum threat: how quantum computers pose risks to current cryptography, especially elliptic curve-based systems used in Ethereum? Our Head of Research and Co-founder @diego_aligned explains in his @EDCON_Official talk:

What this means for users - Scalability and usability will steadily increase over the next few years - It will become possible to build L2s that have very strong scaling and UX properties, that integrate deeply into and benefit from Ethereum L1 - Trust assumptions will steadily

Longer term: Lean Ethereum (Lean Ethereum will be Ethereum 3.0. https://t.co/oe9utARpGR) - Core principles: security, simplicity, optimality - Quantum resistance - Formal verification - Switch to ideal primitives for everything (eg. hashes, signatures, ZKPs) - You can get

Medium term focus: stronger guarantees for transactions - FOCIL - In-protocol full account abstraction

Chainlink: Linking Banks to Blockchains.

Medium term focus: faster slots and finality - Main challenge: how to do this safely - 3SF and similar fast finality ideas - Network optimizations (eg. erasure coding)

Privacy of reads: key technologies - TEE + ORAM - PIR ( Private Information Retrieval) - Partial state nodes - Padding and dummy request techniques (eg. similar to Tor)

Short-medium term focus: Privacy (reads) - How much data are you leaking when you read the chain? - Intermediary minimization: ideally leak to no one except the RPC provider - Hide contents of the read - Hide timing of the read?

Privacy of writes: key technologies - ZK-SNARKs Client-side ZK-EVMYou should be able to prove things that are happening on the Ethereum blockchain, and prove things about EVM computation locally on your machine. And the reason is that we want the privacy Ethereum world and the

Privacy has been probably the big new topic for Ethereum this year. Short term focus: Privacy (writes) - Improve privacy for actions that users take onchain - Payments - Voting - Defi - Account operations (eg. key changes, social recovery)

Short-medium term focus: interoperability - Trustless cross-L2 asset transfers - Fast settlement for L2s (via ZK proofs) - Stage 2 rollups - Proof aggregation (longer term) - L1SLOAD

Short term focus: scaling - Increase L1 gas limit while preserving decentralization - The Ethereum gas limit Increased from 30M → 45M this year - Research underway for safe future increases EIP-4444 ( https://t.co/khFhG7aOCU)→ lighter nodes, and the Ethereum
