What defines this category +
Layer 1s carry the largest community and ecosystem war chests in crypto: across these four, 46-66% of genesis supply sits in community, ecosystem, foundation, or treasury buckets (Aptos 51% community alone; Sui 66% across foundation-managed reserve, treasury, and community programs), because L1s must fund validators, grants, and developer ecosystems for a decade. Insider share (team plus investor rounds) clusters at 32-35% for the modern cohort (Aptos 32.5%, Sui 34%), with earlier or heavily VC-funded launches running higher (Solana ~48% including all private sale rounds, Celestia 53%). Vesting culture is the strictest of any category: a 1-year cliff for team and investors is standard, total vests run 3-4 years (Aptos foundation and community stretch to 10 years), and modern L1s (2022+) launched with exactly 0% of insider tokens liquid at TGE. TGE floats are low, roughly 13-20%, and genesis percentages dilute over time because every L1 here adds staking rewards or inflation on top of genesis supply.
