Constants

const ENOT_GENESIS_ACCOUNT: u64 = 11;

Function GENESIS_ADDRESS

The address of the genesis

public fun GENESIS_ADDRESS(): address

Implementation

public fun GENESIS_ADDRESS(): address {
    @0x1
}

Function assert_genesis_address

Assert signer is genesis.

public fun assert_genesis_address(account: &signer)

Implementation

public fun assert_genesis_address(account: &signer) {
    assert!(Signer::address_of(account) == GENESIS_ADDRESS(), Errors::requires_address(ENOT_GENESIS_ACCOUNT))
}

Specification

pragma opaque;
include AbortsIfNotGenesisAddress;

Specifies that a function aborts if the account does not have the Diem root address.

schema AbortsIfNotGenesisAddress {
    account: signer;
    aborts_if Signer::address_of(account) != SPEC_GENESIS_ADDRESS();
}

Function ASSOCIATION_ROOT_ADDRESS

The address of the root association account. This account is created in genesis, and cannot be changed. This address has ultimate authority over the permissions granted (or removed) from accounts on-chain.

public fun ASSOCIATION_ROOT_ADDRESS(): address

Implementation

public fun ASSOCIATION_ROOT_ADDRESS(): address {
    @0xA550C18
}

Function VM_RESERVED_ADDRESS

The reserved address for transactions inserted by the VM into blocks (e.g. block metadata transactions). Because the transaction is sent from the VM, an account cannot exist at the 0x0 address since there is no signer for the transaction.

public fun VM_RESERVED_ADDRESS(): address

Implementation

public fun VM_RESERVED_ADDRESS(): address {
    @0x0
}

Module Specification

pragma verify;
pragma aborts_if_is_strict;

Specification version of Self::GENESIS_ACCOUNT.

fun SPEC_GENESIS_ADDRESS(): address {
   @0x1
}

Specification version of Self::ASSOCIATION_ROOT_ADDRESS.

fun SPEC_ASSOCIATION_ROOT_ADDRESS(): address {
   @0xA550C18
}

Specification version of Self::VM_RESERVED_ADDRESS.

fun SPEC_VM_RESERVED_ADDRESS(): address {
   @0x0
}
