Seraphis/Jamtis: Feature overview of the proposed upgrade to Monero
summary
Proposes specific protocol changes: adds a viewbalance key so watch‑only wallets and multi‑sig/hardware signing work without exposing spend keys; upgrades ring signatures to support much larger ring sizes; introduces light‑wallet servers that use e‑notes to hide amounts from servers while enabling instant wallet loading (but central servers can still worsen deanonymization); requires migrating to new address format (old seeds remain valid); JamTis standardizes addresses with certified addresses and a generate‑address key, and Seraphis adds transaction chaining to pre‑sign dependent transactions and enable atomic‑swap patterns.
