Keys module
- Private keys of node and sinks (shares) are managed by keys module
- sink_chest is moved here
- Seperate sinkIDs for each service
Sink Private key security improvements
- Shares are stored as index in SQL
- Indexes are mapped with sinkIDs in file system
- File is shuffled on interval
- Every file data is stored in encrypted format
Other changes
- changes required for the above
- RefundTransact is now dedicated to Convert service only (as every service has diff sinkID)
- moved periodicProcess to background.js
- Renamed all `status` columns to `r_status`
- r_status uses INT instead of VARCHAR
- status-codes are used instead of strings
- Codes for status and modes can be found at floExchangeAPI.processCode
- Merged DepositCoin, WithdrawCoin, DepositToken, WithdrawToken into VaultTransactions so that all deposit/withdraw transactions can be viewed in order
- Updated relevant SQL syntaxes for the above
- Converted all multi-valued placeholders in SQL queries to array based placeholders
- Fixed minor bugs
- Fixed: Trade balance not updated correctly
- Fixed: sell-chips were not checked correctly on placing sell orders
- Fixed: sell-chips not added when distributed
- Fixed: sell-chips (FLO) not added when deposited by launch-seller
- Fixed various bugs
- initialPrice will be added to priceHistory table (initially)
- Users can directly login or request without the need for user registration.
- Users can sign the requests either directly with own privateKey or by using a proxy
- Request's timestamp will be checked for Sign expiry.
- Request's sign will be checked for duplication.
- Cash table update will try to insert if record is not there
- Request Log table will also store a boolean value for sign by proxy or not
- Updated the SQL schema for the above changes.
Transfer tokens
- Added transferToken: Users can directly transfer tokens (including FLO) to other registered users.
- Updated schema changes for the above requirement.
- Trade transactions and transfer transactions will generate a txid (using SHA256).
Other changes
- changed all signing type to lowercase
- Removed: Immutable table-type (Previously immutable tables are now considered as mutable tables in backup feature)
- Backup sync-data from master are temporally cached and then processed after receiving all sync-data
- Backup sync-data from cache are now processed in ordered manner (to prevent foreign key constrain error, repeated data, re-adding a deleted data)
- Updated SQL Schema
- Read blockchain for asset's initial price
- Transfer all tokens to new sink on master transfer
Other Improvements:
- Slave: close existing backup sync when master WS closes
- Updated SQL schema, updated SQL syntax as required
2 types of property:
1. Cash - main/central currency used for trading
2. Asset - (FLO/tokens) Can be brought or sold in the exchange market .
- Allow multiple tokens to act as asset in addition to FLO.
- Changes required for the above in deposits, withdraws, placing orders

- Updated SQL schema
- Fixed: error caused during inputRupee
