Sedna: How users can enforce affordable privacy, censorship-resistance and MEV protection in MCP chains

Sedna replaces naive transaction replication in multi-proposer blockchains with rateless erasure coding. Besides improving good put, Sedna preserves censorship resistance and reduces MEV exposure through until-decode privacy. The cost of MEV protection is just 0.04% of the transaction value for realistic scenarios, at negligible latency cost.
