At the genesis of an EOSIO based blockchain, there is only one account present, eosio
account, which is the main system account
. There are other system account
s, created by eosio
account, which control specific actions of the system contract
s mentioned in previous section. Note the terms system contract
and system account
. Privileged accounts
are accounts which can execute a transaction while skipping the standard authorization check. To ensure that this is not a security hole, the permission authority over these accounts is granted to eosio.prods
system account.
As you just learned the relation between a system account
and a system contract
, it is also important to remember that not all system accounts contain a system contract, but each system account has important roles in the blockchain functionality, as follows:
Account | Privileged | Has contract | Description |

eosio | Yes | It contains the eosio.system contract |
