ActiveBlockCount

Like frame_system::block_number, but this one only increments if the parachain status is RUNNING. This variable is used to keep track of durations, such as the issue/redeem/replace expiry. If the parachain is not RUNNING, no payment proofs can be submitted, and it wouldn't be fair to punish the user/vault. By using this variable we ensure that they have sufficient time to submit their proof.

Python

result = substrate.query(
    'Security', 'ActiveBlockCount', []
)

Return value

'u32'

---

IsDeactivated

Python

result = substrate.query(
    'Security', 'IsDeactivated', []
)

Return value

'bool'

---

Nonce

Integer increment-only counter, used to prevent collisions when generating identifiers for e.g. issue, redeem or replace requests (for OP_RETURN field in Bitcoin).

Python

result = substrate.query(
    'Security', 'Nonce', []
)

Return value

'scale_info::187'
