业内借鉴计算机网络通信体系架构的OSI模型(Open System Interconnection Reference Model,即开放式系统互联通信参考模型),将区块链逻辑架构划分为三层——Layer0、Layer1和Layer2。 1) Layer0:对应OSI模型的底层协议,大致包括物理层、数据链路层、网络层和传输层。 2) Layer 1:大致包括数据层、共识层和激励层。我们所...
OSI Layer 1 - Physical Layer In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer. The implementation of this layer is often termed PHY. The physical layer consists of the basic networking hardware transmission technologies of a netwo...
The physical layer, like other layers of the OSI model, is designed to perform a specific task. All of the layers work together to perform the overall function of the model and process. In this case, its main task is to transmit data across a connection, which requires electrical, mechanic...

首先要明确的是,Layer1和Layer2的概念并不单单指的是以太坊网络,而业内借鉴计算机网络通信体系架构的OSI模型(Open System Interconnection Reference Model,即开放式系统互联通信参考模型),将区块链逻辑架构划分为三层——Layer0、Layer1和Layer2。 其中的Layer就是它的最普遍释义——“层”的意思,所谓Layer1和Layer...
网络应用层是通信用户之间的窗口,为用户提供网络管理、文件传输、事务处理等服务。其中包含了若干个独立的、用户通用的服务协议模块。网络应用层是OSI的最高层,为网络用户之间的通信提供专用的程序。 OSI stands for Open System Interconnection is a reference model that describes how information from a software app...
What Does Physical Layer Mean? The physical layer is the first and lowest layer of the Open System Interconnection Model (OSI Model.) Advertisements The physical layer (also known as layer 1) deals with bit-level transmission between different devices and supports electrical or mechanical interfaces...
