key name change post-rebase fixes update nym-connect 'time' dep due to broken semver upload ecash contract to the build server make wasm zknym-lib compile but it won't work properly just yet make wasm zknym-lib compile but it won't work properly just yet fix typo in ecash contract deps make sure to use 0.1.0 sphinx packet optimise pairings in 'check_vk_pairing' derive serde for ecash types simplified g1 tuple byte conversion further optimise the pairing unified signature type + renamed nym-api coconut module to ecash using bincode serialiser for more complex binary types using multimiller loop instead of rayon for verifying coin indices signatures batching signature verification wherever possible feature-locked rayon clippy refactor ecash contract a bit + introduce deposit

duplicate decompression code using deposit_id instead of transaction hash removed freepasses split up ecash handling unified shared state fixed deposit_id parsing log recovered deposit id removed online verification add detailed build info to ecash contract fixed deserialisation of deposit amount received from nyxd queries changed deposit to only persist attached pubkey first iteration of split of verification and redemption basic tool for setting up new network expanded the tool with the option to bypass DKG rename + init network without DKG setting up locally running apis ecash key migration more local functionalities wip fixing sql schemas gateway immediately submitting redemption proposal and getting it passed if valid most of the gateway logic for split redemption with error recovery fixed gateway not persisting ecash signers simplify creation of compatible client create properly serialised ecash key from the beginning rebuild missing tickets and proposals on startup stop ticket issuance during DKG transition fixing build issues split out ecash storage on nym-api side master-verification-key route caching all the signatures and keys implemented aggregated routes for nym-apis swagger UI for ecash endpoints added explicit annotation for index and expiration signatures revamped client ticketbook storage save all recovery information in the same underlying storage wrapper for bloomfilter being more aggressive with marking tickets as used ensure client has correct signatures before making deposit fix deserialisation of AggregatedExpirationDateSignatureResponse + add ticketbook table split nym-api ecash routes handlers into multiple files fixed deserialisation of encoded expiration date add tt_gamma1 to challenge and change naming for paper consistency rotating double spending bloomfilter nym-api test fixes + make sure to insert initial BF params fixed ecash benchmark code updated contract schema updated CI to not upload gateway/mixnode binaries ticket bandwidth revocation added default deserialisation for zk nym config post-rebase fixes |
