tron.logs

​

Table Description

The logs table represents the logs generated by the Tron Virtual Machine (TVM) when a contract is executed. Logs are a way to store data on the blockchain. Logs originate from events that occur during the execution of a smart contract. A log consists of:

• topic list: a list of 0 to 4 32-byte data topics. Topic0 is the hash of the signature of the event (indexed), and the remaining topics are indexed parameters of the event.
• data: contains non-indexed data.

While working with raw logs is possible, we recommend to work with decoded logs for a more user-friendly experience.
