bash blocks-reader

Reads every block and adds it to mongo db server. All transactions are analysed on the database, not relying on sockets incoming transactions for now.

bash payments-incoming

Analyses new blocks searching for incoming transactions for the supernode account, and creates payments or messages actions according to each transaction.

bash payments-outgoing

Announces each payment to the supernode account, splits transactions if needed, control balances, locks and unlocks supernodes accounts.

bash payments-confirmations

Confirms outgoing payments that were waiting to be signed

bash map-xsn

Map all the accounts holding XSN to distribute profits and for community representative decision.

TODO: bash payments-profits-distribution

Sends profits distribution payments to all XSN holders
