Hedera Topics

Ecosphere leverages topics to enable trustless, transparent communication, especially in to provide secure, verified, or timestamped messages.

1. Creating a Topic

• To start, Ecosphere creates a topic by submitting a transaction to the Hedera Consensus Service, which will return a unique topic ID.

• The topic settings include topic name, memo, and permissions (e.g., who can submit messages or delete the topic).

2. Publishing Messages to a Topic

• Once a topic exists, only authorized users can submit messages to it. Each message is hashed, timestamped, and ordered by Hedera nodes, creating an official record of submission.

• This is particularly useful for applications needing immutable message logs like our Climate Nodes.

3. Subscribing to a Topic

• Applications or users can subscribe to a topic to receive messages in real-time. This is Users to keep track of data events or updates as they occur.

• For example, a logistics app might subscribe to a topic where weather updates are published, providing real-time decision making on routing.

By setting up topics and publishing messages to them, Ecosphere leverages Hedera's efficient consensus to achieve verifiable, immutable climate data records for a wide range of applications.
