要更加全面地理解区块浏览器上展示的各项数据,有必要对波场主网的底层基础设施建立一个整体的认知。波场是一个高吞吐量、支持智能合约运行的底层第一层区块链协议,其高效运行依赖于分层的节点网络体系、定制化的虚拟机执行环境以及基于链上投票的去中心化治理机制。 波场网络的基础架构可以划分为核心层、存储层和应用层。核心层是整个区块链的大脑,包含了委托权益证明(DPoS)共识机制和波场虚拟机(TVM)。共识机制负责协调全网节点的出块顺序,而波场虚拟机则负责安全地运行各种复杂代码。波场虚拟机在设计上与以太坊虚拟机保持高度兼容,这使得开发人员可以非常方便地将编写好的 Solidity 智能合约部署到波场网络上,同时配合独特的资源模型,保证了去中心化应用的高效运行。 存储层则决定了区块链数据的持久化方式。为了在保证数据安全的同时实现三秒的高速出块,波场采用了内存数据库与磁盘数据库相结合的结构。新产生的区块首先会在高速内存数据库中进行状态确认,处理可能出现的临时分叉;在获得足够多的节点确认后,数据会被永久写入磁盘键值数据库中。这种设计使得历史交易记录能够被快速检索,同时也为区块浏览器等外部查询工具提供了坚实的数据源。 在节点网络中,不同的节点扮演着不同的角色。最高层级的是二十七个被选举出的超级代表节点,它们拥有专门的高性能服务器硬件,承担着打包交易、生成区块和维护网络共识的核心任务;其次是超级代表候选节点,它们作为后备力量随时准备接替出块;再往下则是广泛分布的全网普通全节点,它们存储着完整的区块链历史账本,向公众提供接口服务,但不直接参与出块。 应用层则是用户与区块链发生交互的桥梁,包含了各种 API 网关和只读区块浏览器。只读区块浏览器通过订阅全节点的数据流,将原本枯燥的二进制数据转化为直观的图表和文字。此外,波场还具备完善的链上治理机制。超级代表们可以针对网络参数(例如调整能量的燃烧单价、修改每日免费带宽额度等)发起治理提案。通过查看区块浏览器上的治理面板,用户可以实时跟踪所有已通过或正在投票的提案,了解波场网络参数的最新变化。 trx地址查询
