Today we will talk abot EOSIO blockchain networks so let get started:
What is EOSIO?
EOSIO is software package that introduces a blockchain design designed to alter vertical and horizontal scaling of decentralized applications (the “EOSIO Software”) and may be wont to launch personal and public blockchain networks. is} achieved through associate operational system-like construct upon that applications can be designed. The software package provides accounts, authentication, databases, asynchronous communication, and therefore the programing of applications across multiple hardware cores and/or clusters. The ensuing technology could be a blockchain design that has the potential to scale to countless transactions per second, eliminates user fees, and permits for fast and straightforward readying of decentralized applications.
Technical options
C++/WASM Virtual Machine
EOSIO uses C++ because the sensible contract artificial language. Given C++ could be a well-liked artificial language among developers round the world, any developer World Health Organization is at home with C++ isn't needed to be told a brand new artificial language to select up EOSIO’s arthropod genus, which can be coated during this onboarding series. Once familiarity with EOSIO’s arthropod genus has been achieved, a developer are going to be ready to program EOSIO sensible contracts victimization canonical C++ code constructs.
On high of EOSIO core layer, a WebAssembly (WASM) virtual machine executes sensible contract code. The WASM commonplace is additionally utilized by alternative net infrastructure software package developed by Google, Microsoft, Apple, and others. the look alternative of victimization WASM allows EOSIO to re-use optimized and battle-tested compilers and toolchains that are being maintained and improved by a broader community. additionally, adopting WASM commonplace additionally makes it easier for compiler developers to port alternative programming languages onto EOSIO.
High output and measurability
EOSIO is intended for achieving high group action throughputs. victimization the agreement mechanism of Delegated Proof of Stake (DPOS), associate EOSIO blockchain network doesn't ought to watch for all nodes to complete a group action to realize conclusiveness. this permits a lot of higher group action output when put next to alternative agreement mechanisms.
Faster Confirmations and Lower Latency
To facilitate smart user expertise, EOSIO is intended to possess low latency for group action confirmation in order that applications designed by developers will vie with non-blockchain, centralized, alternatives.
Feeless and value predictable Blockchain
Applications designed on EOSIO will adopt a freemium model within which users don't seem to be needed to get hold of the price of infrastructure. A user doesn't need to pay a fee to interact. EOSIO blockchains are distinctive in this the infrastructure resource is regulated by a staking mechanism. Infrastructure resource is predicated on token staked in magnitude relation to the full offered resource and is fastened once tokens are staked. this suggests that the infrastructure resource isn't tormented by the value movement of a token of a specific EOSIO based mostly blockchain network when the token has been staked.
Comprehensive Permission Schema
EOSIO contains a comprehensive permission system for making custom permission schemata for numerous use cases. as an example, you'll be able to produce custom permission and use it to safeguard one explicit feature of a wise contract. you'll be able to additionally split the authorities necessary to invoke a wise contract operate across multiple accounts with completely different authority weights. This comprehensive permission system permits developers to make a permissioned application on high of a versatile infrastructure while not having to reinvent the wheel.
Upgradability
Applications deployed on EOSIO based mostly blockchains are upgradeable. this suggests developers will deploy code fix, add options, and/or modification application logic, as long as spare authority is provided. As a developer, you'll be able to repeat your application while not the chance of being locked-in to an error or bug for good. it's additionally potential, however, to deploy sensible contracts that can't be changed on EOSIO based mostly blockchains. These choices are at the discretion of developers instead of restricted by the protocol.
Less energy consumption
With DPOS because the agreement mechanism, EOSIO consumes a lot of less energy to validate transactions and secure a blockchain compared to alternative agreement algorithms
Programmable political economy and Governance
The resource allocation and governance mechanism of any EOSIO based mostly blockchain are programmable via sensible contracts. Developers solely ought to modify the system sensible contracts to vary resource allocation associated governance rules of an EOSIO blockchain. On-chain governance becomes a lot of easier once victimization system sensible contracts, because the base layer code doesn't need to be changed for modification to require place on the blockchain.

Smart Contract/CDT
EOSIO.CDT could be a toolchain for WebAssembly (WASM) and set of tools to facilitate contract writing for the EOSIO platform. additionally to being a general purpose WebAssembly toolchain, EOSIO specific optimizations are offered to support building EOSIO sensible contracts. This new toolchain is made around Clang seven, which implies that EOSIO.CDT has the foremost current optimizations and analyses from LLVM. However, because the WASM target remains thought-about experimental, some optimizations don't seem to be offered or incomplete.
Nodeos
Nodeos is that the core EOSIO node daemon. Plugins is wont to piece nodeos to execute with numerous options. Nodeos handles all peer-to-peer networking, contract code programing, and therefore the blockchain information persistence layer. For development environments, nodeos also can be wont to originated one node blockchain network.
Cleos/Keosd
Keosd could be a key manager for EOSIO accounts that comes with EOSIO.
Cleos could be a command-line tool that let developers act nodeos similarly as deploy, take a look at EOSIO sensible contracts.

Demux
Demux could be a reference implementation of a backend infrastructure pattern which might be wont to route blockchain events from an EOSIO based mostly blockchain to queryable datastores, or also, to trigger facet effects.
