What is the Coin Base Text of a bitcoin block?
What is the Coin Base Text of a bitcoin block? On the site http://ift.tt/2g83ehv , there is a column Coin Base Text with values like Mined by AntPoolk9 Z4,b or *3Zc/http://ift.tt/2AX6DP8 for example. What does it mean? Is it equivalent to the nonce (because I thought, the nonce is always numeric)? And where is this information stored? In each bitcoin block? And why? http://ift.tt/2yJJEkv
