摘要
为了监管账户余额模型公链上的交易,有必要对该类区块链上的交易进行地址分类研究。基于此,提出了一种基于图神经网络的账户余额模型区块链地址分类方法(简称AJKGS-ABCM)以实现区块链地址的分类,为区块链交易追踪提供有效的支持。该方法将区块链交易数据建模为图结构,以地址为节点,交易为边,提出AJK-GraphSAGE算法学习图的嵌入表示,模型的输入只需要节点及其采样的邻居节点集合。同时,模型引入注意力机制及跳跃知识结合策略,自适应地为不同层的表示分配权重,并在不同层间共享信息,提高了训练速度和泛化能力。最后进行了实验对比,结果表明该模型在准确度、召回率和F1分数上性能优于其他方法。
To regulate the transactional activities on the public blockchain involving account balance models,it is necessary to conduct research on address classification for transactions on such blockchains.A blockchain address classification method,named AJKGS-ABCM(attention jumping knowledge graph SAGE account-based blockchain classification model),was proposed to categorize blockchain addresses,providing effective support for blockchain transaction tracking.Blockchain transaction data was represented as a graph structure,with addressed as nodes and transactions as edges.The AJK-GraphSAGE algorithm was introduced to learn embedded representations of the graph,where the model’s input required only nodes and their sampled neighboring node sets.Simultaneously,attention mechanisms and skip-connection knowledge integration strategies were incorporated into the model,allowing for adaptive weight allocation across different layers and information sharing between various levels,thereby enhancing training speed and generalization capabilities.Finally,experimental comparisons are conducted,demonstrating superior performance in terms of accuracy,recall,and F1 score compared to other methods.
