Hi folks,

I'm currently going through the protocol rules coding up a simple example to try and better understand bitcoin.  Specifically, the transaction rules:
https://en.bitcoin.it/wiki/Protocol_rules#.22tx.22_messages

Apologies if some of these are simple questions - I am still somewhat new to this.

> 1. Check syntactic correctness

Is there a formal way to do this or just generally seeing if all the fields can be parsed without an error?

> 3. Size in bytes < MAX_BLOCK_SIZE

I saw in a discussion somewhere this 1,000,000 bytes?  Not sure if this is still the case.  I assume this isn't too important and just to prevent ddos attacks on smaller clients?

> 4. Each output value, as well as the total, must be in legal money range

Does this just mean can't be < 8 decimals places?  I haven't seen any other formal discussion around what a valid range is for an amount.


Thanks for your help!
