Some rough ideas about the future of Offset
Allow payment using a single out of band file exchange (invoice file), instead of two files exchange (invoice + commit).
Allow removing currency after it was added. Might require a zero balance.
Currently the buyer pays fees. Maybe this is a wrong model and the seller should pay fees instead? Check incentives and safety issues around this.
- Extend/rethink index server protocol.
Add cyclic routes search for rebalancing?
Strategy for unfriending: creating a zero balance with a friend by rebalancing.
Rethink numbering of token channel messages and increments during inconsistencies. Can this mechanism be cheated?
Log money gained through commisions? Might be required for tax reports? How to do this elegantly and securely?
Allow payment without an invoice, like a donation?
Decide on the single currency vs multiple currency debate
Dealing with regulations: KYC (Know Your Customer), AML (Anti Money Laundering) and filing taxes?
Update compiler and dependencies
Implement bidirectional connection attempt between nodes, along relays. Currently only one node attempts to connect to the other node, according to the order of public keys.
Solve relay/index server stall bug? Seems to be solved when servers are restarted.
Serialization: Should we change
capnpcommunication serialization to something else? Possibly
Solve issue of running
stcompacton very old android devices (FiatJaf + Blackhole bug)
Implement better searching algorithm for index servers. [Related issue]
Allow seeing relays connectivity status (Online/Offline). Currently only possible for index servers.
Implement Offset application permissions.
Encrypt private key on disk: stnode + stcompact
- Use a better database [Issue]
for node’s database
For stcompact (Mobile app database)
Possibly use sqlite3?
- Transactions interface
Should different node’s applications know about each other’s transactions?
Should there be an option to list all pending incoming/outgoing transactions? If so, how to do this efficiently?
Safe erasure of secret data [Issue]
Exponential backoff for all retrying connectors [Issue]
- Enhance signature security
Should add textual constant prefix to all signatures?
Is the signature malleable? Is this an issue? What can be done to solve?
Offset mobile app¶
Update compiler and dependencies
Better colors for the Offset mobile app (Should be consistent with website)
- Choose better defaults
Card should be enabled when created?
Friend should be open when created?
Currency should be open when created?
Allow sending Offset data as text? (Currently can send as files or QR codes)
Merge incoming/outgoing transactions into one screen (Requested by awpcrypto)
Keep purchase history (Incoming/Outgoing) forever.
Add transaction time and date (stcompact)
Password for locking/unlocking the Offset app.
- Support Importing/Exporting
Nodes (Private key + database)
Make it easier to add friends, while still keeping it safe?
Implement bill splitting using Offset? [Issue]
Include different assets for different architectures during build in an elegant way (Currently done using a bash script).
Add mobile app to F-Droid store [Issue]
High quality video tutorials
Document multi-currency feature.
Document security considerations: What makes Offset secure?
