 ## Block Issuer Feature
 
 The presence of a _Block Issuer Feature_ on an account signals that this account can issue blocks - it is a _block
-issuer account_. This feature defines the public keys with which signatures on blocks can be verified. A block issued
-from this account with a verified signature will burn Mana from the account's Block Issuance Credit (BIC) balance. If
-the balance becomes negative, the account is locked, meaning its output cannot be spent and it can no longer be used to
-issue blocks. Once locked, an account can only be unlocked by allotting enough Mana to the account's BIC balance for it
-to become non-negative again. Because the account itself cannot issue such a transaction, the block containing the
-alloting transaction must be issued by another account. The feature can only be removed with an expiration mechanism in
-order to disincentivize malicious behavior when issuing blocks. Any Mana generated or stored by an issuer account is
-locked to that account.
