Height

Height is used interchangeably with blockchain length.

User Command Status

User commands can be Applied or Failed and this status is determined at the time a block is produced. Thus, user command status does not depend on canonicity.

All user commands require a > 0.0 fee.

No fees are paid unless a block is canonical.

• Applied

• Failed

  • Why? One possible failure reason could be insufficient funds.

Block Canonicity

Canonicity is an emergent property, because a block is only canonical or non-canonical in retrospect.

• Canonical: The best block or a descendant of the best block

• Pending: Transaction that has been gossiped and buffered in a Node's mempool

• Finalized: Transaction/block has > k (=290) confirmations

Mina Indexer Specific

The following information will be most helpful for developers working on Mina Indexer.

• Deep Canonical: Canonical blocks with a minimum of x threshold confirmations

• Recent: Any blocks (in the provided directory) that have a higher height (blockchain length) than the highest Deep Canonical block
