4/ 🧵
Solana claims up to 65,000 transactions per second (TPS) using Proof of History (PoH) alongside PoS, dwarfing Hive’s estimated 10,000 TPS ceiling. It’s fast—sub-second finality—and supports dApps like Serum, but it charges small fees (around $0.00025 per transaction) and has faced outages, raising questions about reliability. Solana’s centralization is also debated; its validator requirements (high-end hardware) limit who can participate compared to Hive’s lighter DPoS setup.
Cardano offers a different angle. It’s research-driven, using Ouroboros PoS for security and scalability. It’s slower than Hive (about 7-10 seconds per transaction) and has modest fees, but it’s designed for long-term sustainability and formal verification of smart contracts—something Hive doesn’t emphasize. Cardano’s ecosystem is growing (e.g., SundaeSwap), but it’s not as focused on zero-fee, instant-use cases like Hive.
