Tech: Atomic Transaction

[astaphobia]

Description

Create new transaction type called Atomic. Inside Atomic transaction can includes multiple different transactions with different senders as well, and those could validate on the fly.
Don't miss add in Rollback and Snapshot also.

The Atomic transaction body:

// UnsignedTransactionBytes is collection of unsigned transaction bytes
UnsignedTransactionBytes [][]byte 
// Signatures is <addressHex, Signature>
Signatures           map[string][]byte

And when parsed to single bytes collection should like:

buff.Write(util.ConvertUint32ToBytes(uint32(len(tx.Body.GetUnsignedTransactionBytes())))) // total unsigned inner transactions
for _, unsignedTX := range tx.Body.GetUnsignedTransactionBytes() {
	buff.Write(util.ConvertUint32ToBytes(uint32(len(unsignedTX))))
	buff.Write(unsignedTX)
}
buff.Write(util.ConvertUint32ToBytes(uint32(len(tx.Body.GetSignatures())))) // total signatures
for addressHex, signature := range tx.Body.GetSignatures() {
	var addressBytes []byte
	addressBytes, err = hex.DecodeString(addressHex)
	if err != nil {
		return bodyBytes, err
	}
	buff.Write(addressBytes)
	buff.Write(signature)
}

Breakdown

• Atomic transaction type
• Add table atomic_transaction and also the schema
• Rollback
• Snapshot integration
