Evaluation of Blockchain Service Level Agreement (SLA) Using Hyperledger Fabric (HLF)

Abstract

Different sectors are being revolutionized by distributed ledger technology.According to the 2022 market valuation, Hyperledger is now the second-largestblockchain platform for smart contracts. The creation of numerous apps maybe sped up and simplified with smart contracts, but there are certain drawbacks as well. For instance, vulnerability contracts are created intentionallyto weaken candor, smart contracts are employed to conduct fraudulent activities, and there are many redundant contracts that squander the efficiency ofthe system for no real reason. To solve these problems, we provide in thisresearch Service Level Agreement(SLA) for Hyperledger smart contracts. Wecreated Hyperledger smart contracts and focused on how smart contracts andconsumers used data. By manually analyzing the transactions, we were ableto extract four behavioral characteristics that may be used to differentiatebetween various contract types. Then, a smart contract is built using theseto include 14 fundamental functionalities. We provide a data splitting algorithm for splitting the gathered smart contracts in order to create the experimental dataset. Then, we train and test our dataset using an LSTM network.The comprehensive experimental findings demonstrate that our method can discriminate between various contract types and may be used to identify maliciouscontracts and detect anomalies with acceptable precision, recall, and F1-score.
