+I have introduced a new table called transactions, @schemas/table_transactions.md 
+
+I need all RC related transactions logged in here. This is to keep track of all purchases of RC, spendings of RC and withdrawals of RC in track.
+
+I have added my first record with remarks of 'supply',to acc id:1. a large sum.
+
+All purchases of RC (in purchases rc api endpoint) will be deducted from acc id:1 and given to the requested user.
+
+During reward distribution, Record the bet fee going to the acc id:1 and prize going to the winner seperately. and set match_id on reward distribution  .
+
+Heres how a RC purchase record would look like
+
+from: 1
+to: requested_user_id
+amount: requested_amount
+remarks: purchase
+
+
+Heres how a reward distribution would look like.
+
+from a single players POV (there are 2 players per match).
+PS: bet fee is usually 10%, stored in settings table
+entry record 1/2
+
+from: user_id
+to: 1
