Block Analyzer (Project: ms_block_analyser)

The Block Analyzer service watches for new blocks with transactions in the blocks collection (the result of the heartbeat service) and parses them.***

PubSub (Celery + Redis)

Many parts of the CCE Explorer Universe work together through a pub/sub service, using Celery + Redis.

The block analyzer service sends out messages on various topics, depending on the type of transaction(s) found. Other services listen to their specific topics and act on them.

The following topics are published when they occur in a block.

Topic	Subscriber
indexers	Triggered for every transaction, see MS Indexers
events_and_impacted	Triggered for every transaction, see MS Events and Impacted
account_creation	Triggered for a new acccount, see MS Accounts
contract	Triggered for a new or upgrade smart contract (also called instance), see MS Instances
module_deployed	Triggered for a new module deployed, see MS Modules
plt	Triggered for for a new PLT deployed and/or a token update transaction, see MS PLT
token_accounting	Triggered for CIS-2 transactions, see MS Token Accounting
metadata	Triggered by token_accounting for CIS-2 transactions, see MS Metadata
