Quick Overview: Cosmos-SDK and CometBFT

ELDER protocol is built using cosmos-SDK on top of cometBFT consensus

Cosmos-SDK

Cosmos-SDK is a framework for building blockchain applications in the Cosmos ecosystem. It's designed to simplify the process of creating custom blockchains that can interoperate with one another.

Key Features

• Modularity: Developers can build blockchain applications using pre-built modules like staking, governance, or custom modules tailored to specific needs.

• Interoperability: Through the Inter-Blockchain Communication (IBC) protocol, chains can communicate and transfer assets or data securely.

• Flexibility: Offers the ability to define custom business logic in Go, allowing for highly specialized blockchains.

• Community: Backed by a vibrant developer community contributing to its ecosystem.

CometBFT (formerly Tendermint Core)

CometBFT is a battles-tested Byzantine Fault Tolerant (BFT) consensus engine that ensures that all nodes in a network agree on the state of the blockchain. It's the underlying consensus mechanism for Cosmos SDK-based blockchains.

Key Features:

• BFT Consensus: Uses a variant of Practical Byzantine Fault Tolerance for fast finality and network security.

• Modular Design: Separates the consensus mechanism from the application layer, allowing for reuse across different applications.

• State Sync: New nodes can quickly sync to the latest state without downloading the entire history, enhancing scalability.

• Light Clients: Supports light client proofs for efficient blockchain verification on resource-constrained devices.

Together in Action:

• Cosmos Hub: The first blockchain built with Cosmos-SDK using CometBFT for consensus, acting as the center of the Cosmos ecosystem.

• Interoperability: Chains built with Cosmos-SDK can leverage CometBFT's consensus for secure cross-chain transactions via IBC.

Cosmos-SDK and CometBFT are key technologies enabling developers to build interoperable, scalable, and secure blockchains. They provide a foundation for innovative blockchain networks, integrating IBC for communication and surpassing traditional development hurdles.
