Title: What is the size of a block? Post by: papa_snurf on July 09, 2011, 07:59:23 AM ...and what is the size of a transaction? How many transactions can be written per block?

Title: Re: What is the size of a block? Post by: patvarilly on July 10, 2011, 07:05:01 AM It varies block by block, but they're generally 10-100 K. You can see the size of any single block in blockexplorer:

Transactions are roughly proportional in size to the number of inputs and outputs they string together. The generic transaction (me sending a bit to you and the rest back to myself) is about 250 bytes long, but you can have much larger transactions in general. A priori, apart from the soft limit on block size that is currently active, there is no technical limit on the number of transactions that can be strung together into a single block. Practical limits are a more complicated issue, discussed at length here: https://en.bitcoin.it/wiki/Scalability http://forum.bitcoin.org/?topic=286.0 |
