Title: How much BTC does it cost to build a transaction that only contains OP_RETURN? Post by: Staizita on December 04, 2018, 09:15:23 AM How much BTC(at least) does it cost to build a transaction that only contains OP_RETURN(OUTPUT)?
Is there any information about this? Title: Re: How much BTC does it cost to build a transaction that only contains OP_RETURN? Post by: Coding Enthusiast on December 04, 2018, 10:40:59 AM Nearly the same as when you make a payment to a legacy address!
TX Size = 4 byte version 1 byte txInCount TxIn: 36 byte outpoint 1 byte scriptLength 72 byte script 33 byte public key 4 byte sequence 1 byte txOutCount txOut: 8 byte amount 1 byte size of script 1 byte OP_Return + 1 byte size of the data + (0 to 40 bytes) 4 byte locktime Min size=167 bytes Multiply that with fee in satoshi/byte unit and you will get how much it can cost. If you use SegWit then you have to calculate virtual size which is 89 vbytes so it an cost even less. |
