Title: Why are scripts needed in transaction?
Post by: rfisher1968 on January 24, 2016, 04:06:43 PM
In the below transaction I know why the scripts are needed. The question I have is why can't you just do something like: input_txid + output_txid + HASH160(pubkey) + amount + fee + signature(input_txid + output_txid + HASH160(pubkey) + amount + fee) Hoping for some input, good or bad. #394788

} Scripts allow you to do other things since they specify how you that output can be spent. Those allow special nonstandard transactions for both experimenting and creating more features.
