UkoeHB submits new CCS proposal to continue working on Seraphis wallet PoC

UkoeHB¹ has submitted a second CCS proposal² to continue working on the Seraphis³ wallet proof-of-concept:

Hi all, I closed out my previous Seraphis Wallet PoC CCS after consuming all the hours. There are additional tasks I would like to work on.

Total funding: 128 XMR (50 USD + 0.2 XMR Rate).

ETA: TBD (16 weeks @ 20hr/wk = 320hrs).

Tasks overview

• Add tx builder plumbing for discretized tx fees.
• Consider using 16-byte address indices (instead of 7), with 2-byte encoded address index MACs (instead of 1)
• Implement a robust ‘input selection’ solver that takes advantage of statically-determinable tx weights.
• Implement a maximally-efficient and generic enote-scanning workflow.
• Build a wallet proof-of-concept that demonstrates all the ‘transaction engineering’ capabilities and implementation modularity of Seraphis/Jamtis.
• Test out using x25519 for enote ECDH instead of ed25519, which may speed up enote scanning by a non-trivial amount (>10%).
• Miscellaneous code cleanup.

Update 22/5/18: moved to funding stage⁵ (100% funded).

Update 22/7/17: there will be no wallet PoC and the remaining CCS time will be spent finishing the core library, according to UkoeHB’s recent MRL meeting statement⁶.

Update 22/8/19: work finished, summary available⁷; new CCS proposal was submitted⁸.
