Recent advances in blockchain technology have led to a significant interest in developing blockchain-based applications. While data can be retained in a blockchain, the stored values can be deleted or updated. From a user viewpoint that searches for data, it is unclear whether the discovered data from the blockchain storage is relevant for real-time decision-making processes for block-chain-based applications. The data freshness issue serves as a critical factor, especially in dynamic networks handling real-time information. In general, transactions to renew data require additional processing time inside the blockchain network, which is called ledger-commitment latency. Due to this problem, some users may receive outdated data. As a result, it is important to investigate if the blockchain is suitable for providing real-time data services. In this article, we first describe block-chain-enabled (BCE) networks with Hyperledger Fabric (HLF). Then, we define age-of-information (AoI) of BCE networks and investigate influential factors on this AoI. Experiments are conducted to explore the impacts of the influential factors on data freshness in BCE networks. Lastly, we conclude by discussing future challenges.

区块链是否适合数据新鲜度？信息时代的视角

区块链技术的最新进展引起了对开发基于区块链的应用程序的浓厚兴趣。虽然可以将数据保留在区块链中，但是可以删除或更新存储的值。从搜索数据的用户角度来看，目前尚不清楚从区块链存储中发现的数据是否与基于区块链的应用程序的实时决策过程相关。数据新鲜度问题是一个关键因素，尤其是在处理实时信息的动态网络中。通常，用于更新数据的交易需要在区块链网络内进行额外的处理时间，这称为分类账承诺等待时间。由于此问题，某些用户可能会收到过时的数据。因此，调查区块链是否适合提供实时数据服务非常重要。在本文中，我们首先介绍使用Hyperledger Fabric（HLF）启用块链（BCE）的网络。然后，我们定义了BCE网络的信息时代（AoI），并研究了影响该AoI的因素。进行实验以探索影响因素对BCE网络中数据新鲜度的影响。最后，我们通过讨论未来的挑战来得出结论。
