And my personal focuses for 2025:
1. Ethereum, particularly:
(i) L1 long-term roadmap (eg. single-slot finality, long-term VM, statelessness, security / resilience / decentralization)
(ii) full-stack security, open source and privacy: ensuring Ethereum is usable in a way that is highly secure, free of centralized intermediaries and privacy-friendly, incl higher up the stack (apps, wallets...)
2. Big-picture d/acc (see https://vitalik.eth.limo/general/2025/01/05/dacc2.html ):
* comms tools, info and social layer, mechanism design eg. governance, pubgoods/open source funding
* cryptography, OS, hardware, physical infra, bio defense
Meanwhile areas that are important but where I am relatively less involved (and others excel):
* @gakonst @ansgar.eth @dankrad and others are taking on practicals of short-term scaling (eg. 10x the L1 gaslimit within 2026)
* p2p, block construction, other research areas
* @hww @tkstanczak are leading many EF matters
* proven app layer categories (eg. defi, payments/savings) 24 replies
