Blocks

​

What do the fields of a block mean?

​

What does block not in canonical chain mean?

This means that the block has been orphaned and is not in the main chain. There will be no block rewards for these blocks and there will be no balance changes as a result of transactions included. There can be more than one block producer per slot due to the way block producers are selected. So if two (or more) blocks are produced for the same slot, it will cause a short fork, and only one will be chosen - the winner in this instance is random based on the VRF output for each block producer. It is also possible to produce a block in catchup, and this block will also be quickly orphaned as it is not building on the correct height.

Accounts

​

My account is not listed in the ledger page

This data is from the staged ledger and is updated periodically and is not real-time. It should be used as an overview of the top holders in Mina and not an accurate reflection of balances. You can query any information for an account directly on the account page.

​

Transactions

​

My transactions are stuck as pending

Transactions with higher fees are given priority when being included in blocks. As a result some transactions with lower fees may become stuck until eventually included in a block, replaced with a higher fee transaction, or evicted from the transaction pool when it becomes full and there is a higher fee.

​

Staking Ledger

​

My balance or delegation in the staking ledger has not been updated

Changes to the staking ledger are made once per epoch at the start of the epoch. The current epoch staking ledger is the snarked ledger of the last block of current epoch - 2. So, if you receive funds at the start of epoch 4, they will not be considered until the start of epoch 6. The same is true of sending delegation transactions, any delegations are only taken into account when the staking ledger is updated.
