Kadena Introduction
Kadena is a blockchain project designed to offer a scalable, high-performance private blockchain solution. Its primary goal is to address the limitations of current blockchain technologies, particularly in private or permissioned settings, by implementing a novel consensus protocol known as ScalableBFT. Kadena aims to provide the performance and scalability required for industrial and enterprise applications, which have been challenging to achieve with existing blockchain technologies.

Description: What Does Kadena Do?
Kadena aims to provide a scalable, high-performance private blockchain solution. The primary goal is to address the challenges of achieving both high performance and scalability in private blockchain settings by utilizing the ScalableBFT consensus protocol.
The methodology involves leveraging principles from Tangaroa and Juno BFT-Consensus protocols to develop a predictive model for Kadena's performance. This model guided the design and implementation of the ScalableBFT protocol, which Kadena uses to achieve its scalability and performance goals.
Problem: Why Kadena Is Being Developed?
Kadena is being developed to solve the problem of scalability and performance in private blockchains. The current solutions either offer high performance or scalability but not both, which limits their industrial adoption.
Existing solutions like mining-based systems are slow and do not meet enterprise performance requirements. Other BFT-Consensus algorithms face performance degradation as the cluster size increases. Kadena aims to address these limitations through its unique ScalableBFT protocol.
Use Cases
- Supply Chain Management: Ensures transparent, immutable records of goods as they move through the supply chain.
- Healthcare: Provides secure, verifiable, and immutable records for patient data management.
- Finance: Facilitates high-speed, secure transactions and record-keeping for financial institutions.
How Does Kadena Work?
Kadena consists of the ScalableBFT consensus protocol, which is designed to provide high performance and low latency. It leverages cryptographic techniques like Merkle trees for transaction verification, ensuring immutability and security.
The project's operation includes the following steps:
- Transaction Submission: Transactions are submitted to the blockchain.
- Replication: Transactions are replicated across all nodes in the cluster.
- Consensus: Nodes reach consensus using the ScalableBFT protocol.
- Verification: Transactions are verified via cryptographic methods.
- Commitment: Verified transactions are committed to the blockchain.
Technical Details
Kadena utilizes a private/permissioned blockchain with the ScalableBFT consensus mechanism. This protocol is designed to scale effectively with increasing nodes, providing high throughput and low latency.
Key technologies and methods include:
- ScalableBFT: A deterministic consensus protocol designed for high performance.
- Merkle Trees: Used for verifying transaction immutability.
- Cryptographic Signatures: Ensures transaction authorship and security.
