The getblocktemplate
RPC method accepts a parameter, reserve_size
. What does it do and what are its valid values?
1 Answer
The reserve_size is the amount of data to reserve in the block template for the extra nonce (arbitrary data which may be embedded in a transaction). The maximum amount is 255 bytes. This is used by the pool code to place a nonce which will be incremented to try to find a block hash below the current difficulty target.
