The following algorithm is build to reduce the fee of multiple transaction using an aggregation technique

• bitcoind

The method used is by waiting for transaction to accumulate during a time period than use the aggregation algorithm to produce optimize large transactions

• aggregate all shared inputs into single transactions
• calculate maximal change for each transaction ( with no fees )
• build transaction acumiltivly whatching transaction size
• once optimal transaction size is reached continue
• remove minimal fees from the built transaction
• aggregate all shared outputs
• create the actual bitcoin transaction
• sign the transaction using all the needed private keys
• repeat the build stage for all transactions left
• wait 168 hours for the next time to run the script

Fisrt you need to change the credentails to access the bitcoind server

bitcoind = ServiceProxy("http://lior:lior1@127.0.0.1:8332")

Then you need to change the mock function

txs = get_transaction_log()

To get transactions from the actual api

Than just run main.py
