Multi-proposer chains usually replicate every transaction across proposers, collapsing throughput of 'good' transactions.
Instead, Sedna will encode each transaction into fragments, providing censorship resistance, pre-execution privacy and MEV resistance.
Sei Giga v2, part 4: Sedna.
MCP is great for throughput and censorship, but introduces duplication.
Aptos claims 160k tps, but some transactions appear duplicated nearly 100 times, reducing their useful throughput by up to 100x (1.6k tps).
Sedna fixes this for Sei Giga 🧵
