Input Endorsers on Cardano are part of a planned optimization to improve the blockchain’s scalability and transaction throughput. This concept aims to separate the process of transaction validation from block production, allowing for greater parallelism and efficiency in how transactions are handled. Here’s how Input Endorsers work and their significance:
- Separation of Concerns: In the traditional blockchain model, block producers (miners or validators) are responsible for both selecting and validating transactions, as well as creating blocks. With Input Endorsers, these tasks are separated. The block producer focuses on block creation, while Input Endorsers are responsible for validating transactions independently of the block production process.
- Parallel Transaction Validation: Input Endorsers validate transactions before they are added to a block, allowing for many transactions to be endorsed (or pre-validated) in parallel. This reduces the computational load on block producers and enables a higher throughput of transactions, as they can be processed more efficiently.
- Faster Transactions: Because Input Endorsers pre-validate transactions, this can lead to lower latency in transaction processing. Users may experience faster transaction finality since endorsed transactions are essentially ready to be included in a block, streamlining the process.
- Improved Throughput: The decoupling of transaction validation from block production is expected to significantly increase the number of transactions Cardano can handle per second. This is crucial for supporting the growing ecosystem of decentralized applications (dApps), smart contracts, and users on the network.
- Enhanced Security and Decentralization: By distributing responsibilities between Input Endorsers and block producers, the system maintains decentralization while improving scalability. It reduces the bottleneck caused by the block production process, enhancing the security and efficiency of the network.
In summary, Input Endorsers are a proposed feature to boost Cardano’s scalability by allowing for more efficient and parallelized transaction validation, helping the network accommodate a larger number of users and transactions without sacrificing decentralization or security.
