Which class of communication protocols are blockchains generally built on

ICON is a blockchain and communications mechanism following a hub-and-spoke model. It seems to be mainly modelled after existing fiat financial exchanges and has a governance mechanism much more reminiscent of existing real-world representative democracy A blockchain is a growing list of records, called blocks, that are linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree).The timestamp proves that the transaction data existed when the block was published in order to get into its hash

Use of Cryptography in Blockchain. Blockchains make use of two types of cryptographic algorithms, asymmetric-key algorithms, and hash functions. Hash functions are used to provide the functionality of a single view of blockchain to every participant. Blockchains generally use the SHA-256 hashing algorithm as their hash function To overcome these technical barriers, we are collaborating on decentralized Layer 2 protocols that run atop these public blockchains to achieve global scale, while preserving the attributes of a world class DID system. Accessible to everyone TCP/IP has become ubiquitous, and blockchain applications are being built on top of the digital data, communication, and computation infrastructure, which lowers the cost of experimentation and.

The blockchain is a software protocol (like SMTP is for email). However, Blockchains could not be run without the Internet. It is also called meta-technology as it affects other technologies. It is comprised of several pieces: a database, software application, some connected computers, etc The OSI stands for Open System Interconnection, which was developed in 1980s. It is a conceptual model used for network communication. It is not implemented entirely, but it is still referenced today. This OSI model consists of seven layers, and each layer is connected to each other

There are a great number of protocols in use extensively in networking, and they are often implemented in different layers. Some low level protocols are TCP, UDP, IP, and ICMP. Some familiar examples of application layer protocols, built on these lower protocols, are HTTP (for accessing web content), SSH, TLS/SSL, and FTP Polkadot is a Layer-0 protocol that has been architected to enable best-in-class, cross-chain interoperability and innovate new types of on-chain governance In October 2016, the Berkeley Bitcoin Association, a group of about a dozen members, founded Blockchain at Berkeley, an organization dedicated to becoming the blockchain hub of the East Bay. They also debuted the world's first undergraduate university-accredited blockchain course, Blockchain Fundamentals, taught to about 50 students

Communication skills are vital to a healthy, efficient workplace. Often categorized as a soft skill or interpersonal skill, communication is the act of sharing information from one person to another person or group of people. There are many different ways to communicate, each of which play an important role in sharing information Advantages of LAN. Resource Sharing: Computer resources like printers, modems, DVD-ROM drives and hard disks can be shared with the help of local area networks. This reduces cost and hardware purchases. Software Applications Sharing: It is cheaper to use same software over network instead of purchasing separate licensed software for each client a network A transport layer is required for transporting data beyond the boundaries of an address space. From the point of view of the transport layer, the data being transported consist of unstructured byte sequences. The transport layer is implemented by a concrete transport mechanism. The task of the transport layer is to abstract from platform-specific transport mechanisms and to offer a homogeneous. Indirect communication establishes like only when processes share a common mailbox each pair of processes sharing several communication links. Shared memory is a memory shared between two or more processes that are established using shared memory between all the processes. Inter Process Communication method helps to speedup modularity

An IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network.Addresses in IPv4 are 32-bits long. This allows for a maximum of 4,294,967,296 (2 32) unique addresses.Addresses in IPv6 are 128-bits, which allows for 3.4 x 10 38 (2 128) unique addresses..

Communications between computers on a network is done through protocol suits. The most widely used and most widely available protocol suite is TCP/IP protocol suite. A protocol suit consists of a layered architecture where each layer depicts some functionality which can be carried out by a protocol The HART Protocol is a master-slave communication protocol which means that during normal operation, each slave (a field device) communication is initiated by a request (or command) from the master (host) communication device. The master or host is generally a distributed control, PLC, or PC-based asset management system for example Transmitting Data Securely. One important aspect of computer security is the secure communication of data over a network. Although you can devise your own security protocols and use low-level APIs to implement them, it's best to use standard protocols as much as possible, and the highest level API that supports them
