An ELI15 presentation discussing the importance of full chain membership proofs, how they can be implemented (various forms of merkle tree accumulators), how they'll fit into Seraphis, and the current work being discussed (moving to a curve cycle) to ensure they remain accessible. It'll also cover why moving to a curve cycle now is so important, despite not discussing moving to SNARKs now, and the prior roadblocks to changing curves we now have solutions for.
