Fantom co-founder Andre Cronje, recognized as the godfather of decentralized finance (DeFi), further raised concerns over probabilistic finality in blockchains including Bitcoin and Ethereum as the market witnesses expanding use cases and adoption in traditional finance. He stated Fantom has already addressed state bloat as Ethereum developers seek to tackle state bloat in the chain.
Andre Cronje: “Fantom Has Resolved The Bloat Issue”
In response to Ambient Finance founder Doug Colkitt’s belief that Ethereum is the sole chain looking to address state bloat in its long-term plan, Andre Cronje remarked, “I am fairly certain we have already resolved state bloat.” Ethereum roadmap entails employing Verkle trees to enable “data to be compact enough to be affixed to every block.” This could assist validators and nodes in becoming stateless as all ‘state’ can be stored more efficiently off-chain.
Time to Finality
Andre Cronje mentioned that any blockchain utilizing probabilistic finality or any variation of the longest chain rule won’t tackle this problem. Bitcoin and Ethereum chains rely on probabilistic finality. Finality refers to when a block of transactions is considered permanent and cannot be altered or reversed.
Fantom employs aBFT (Asynchronous Byzantine Fault Tolerance) consensus mechanism, which does not necessitate the longest chain rule.
Furthermore, Fantom introduced the novel database Carmen, a flat storage method that abstains from using tree or dictionary structures while preserving a cryptographic signature of the world state. This significantly diminishes the bloat of the current active state (two epochs). Carmen facilitates real-time pruning, and although archive nodes still need to retain all data, most validators can enable pruning.
After embracing the aforementioned technology, Fantom’s status is reduced from approximately 2TB (archive) to 60GB (archive). Cronje mentioned state bloat has been one of Fantom’s core milestones since its early days.
