Smart Contract Broker: Improving Smart Contract Reusability in a Blockchain Environment

In this paper, we propose a smart contract broker to improve the reusability of smart contracts in a blockchain environment. The current blockchain platform lacks a standard approach to sharing and managing smart contracts, which makes it difficult for developers to reuse them and leads to efficiency issues. The proposed smart contract broker uses tags to identify and organize smart contracts, and it provides an environment for comparing and reusing smart contracts. This improves the reusability of smart contracts and efficiency. The proposed smart contract broker can be applied as a reference model that increases the flexibility and reusability of smart contract management in a blockchain environment.
