Top EVM (Ethereum Virtual Machine) compatible networks

Ethereum’s vision is clear from the day one. That is to become a “world computer” or an “internet computer”. It’s the worlds first programmable blockchain. So how does it accomplish this? The answer lies in the EVM.

EVM also known as Ethereum Virtual Machine. EVM is a computation machine which works like a decentralized computer. It is a powerful, sandboxed, virtual machine that is embedded within each node. Every full Ethereum node runs on the EVM to maintain consensus across the blockchain.

The role of EVM is to execute and deploy smart contract. It is basically responsible for facilitating smart contract functionality where the contracts are usually written in higher level programming languages like Solidity.

Ethereum Virtual Machine is a runtime environment for every smart contract – A Turing complete virtual machine that executes code exactly as intended. EVM has millions of executable projects. It can deploy number of extra functionalities to the blockchain and it is the core of the Ethereum’s entire operating structure.

In this article you will see Top 20 EVM compatible networks

Name/Coin/TokenDescribePrice overviewWebsite
BNB Smart Chain - BNB

BNB Smart Chain (formerly Binance Smart Chain) is a blockchain developed by Binance, one of the leading cryptocurrency exchanges, using Proof of Staked Authority (PoSA).

BSC supports smart contracts and is EVM-compatible, allowing developers to deploy smart contracts and build DApps on BSC conveniently. Compared with Ethereum, the transaction fees are lower and confirmation time is faster.

BSC adopts Proof of Staked Authority (PoSA), which allows holders of its native token, BNB, to vote for 41 validators. 21 validators of them are responsible for on-chain transaction validation and block production, while the other 20 serve as candidate block producers.

BSC produces 1 block every 3 seconds, and when a validator produces a valid block, he will be rewarded with the miner's fee for all transactions in the block, but unlike Ethereum and Bitcoin, BSC validators do not have block rewards.

Polygon - MATIC

Polygon

  • Polygon, formerly known as the Matic Network, is a scaling solution that seeks to give several methods to boost the speed of transactions on blockchain networks while also lowering their cost and complexity.
  • Polygon describes itself as a layer-2 network, which means it is an add-on layer to Ethereum that does not attempt to alter the original blockchain layer.
  • Like its geometric namesake, it has numerous sides, shapes, and applications, and it promises to be a more straightforward framework for creating interconnected networks.

Matic

  • After the rebranding, Polygon retained its MATIC cryptocurrency, the digital coin underpinning the network. 
  • MATIC is the payment and settlement unit for participants who engage within the network and is also utilized to keep tokens safe on the Polygon network.
  • The MATIC cryptocurrency is available on several well-known decentralized and centralized trading platforms, including Binance, 1inch Exchange, and Coinbase Pro.
  • The crypto community is gathering together to make it easier to buy Polygon (MATIC) tokens by making them available in both fiat and crypto.

Features of Matic

  • It provides blockchain performance enhancement technologies like sidechain, which was one of the first things they offered to improve its performance. Transactions are processed faster, and the fee is significantly lower.
  • Its primary goal is to create a foundation for blockchain networks. Instead of being completely disconnected, users would be able to establish blockchain networks that interconnect.
  •  It is Ethereum Virtual Machine (EVM) compatible. Because Polygon is EVM compatible, developers can easily port their apps to it. Aave and SushiSwap are two of the popular Ethereum apps that have already been deployed on Polygon.
  • Other blockchain networks, such as Ethereum 2.0, may pose certain difficulties. Polygon is one of the blockchain network projects under development to avoid these challenges. Polkadot and Avalanche also provide interconnected blockchains. 
  • Fees, governance, and staking are all handled through the Polygon token.

Avalanche - AVAX

Avalanche is a layer one blockchain that functions as a platform for decentralized applications and custom blockchain networks. It is one of Ethereum’s rivals, aiming to unseat Ethereum as the most popular blockchain for smart contracts. It aims to do so by having a higher transaction output of up to 6,500 transactions per second while not compromising scalability.

This is made possible by Avalanche’s unique architecture. The Avalanche network consists of three individual blockchains: the X-Chain, C-Chain and P-Chain. Each chain has a distinct purpose, which is radically different from the approach Bitcoin and Ethereum use, namely having all nodes validate all transactions. Avalanche blockchains even use different consensus mechanisms based on their use cases.

Moonriver is an Ethereum-compatible, smart-contract parachain on Kusama. It is intended to be a companion network to Moonbeam, where it will provide a permanently incentivized canary network. New code will ship to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code will ship to Moonbeam on Polkadot.

It does this by providing a full EVM implementation, a Web3-compatible API, and bridges that connect Moonriver to existing Ethereum networks.

This allows developers to deploy existing Solidity smart contracts and DApp frontends to Moonriver with minimal changes.

Eternal Storage : Building Dapps For the Future | Hacker Noon

TLDR: Eternal Storage provides the stable and flexible base needed to build and maintain long-lived decentralized applications.

Once deployed to a network, smart contract logic cannot be altered. However, developers are not perfect. Bugs are bound to loom in our logic no matter how carefully we plan our logic, test it, and have it externally audited. Iteration is inevitable in any complicated application, decentralized or not. Smart contracts will need to be updated and redeployed during the lifetime of a decentralized app (dapp). In this post we will learn about the Eternal Storage pattern and why it’s an elegant answer to our need for mutability in an immutable world.

This article makes the assumption that the reader has some basic understanding of writing smart contracts in Solidity?ref=hackernoon.com) and deploying and testing them locally (we like Truffle). Some patterns are based off examples from EIP#930fravoll, and RocketPool.

To illustrate the typical evolution of a dapp, let’s consider a potential implementation of Decentralized DNS. The most basic functionality required in a first iteration might include:

  • Claiming a domain
  • Only allowed if domain is not already claimed
  • Releasing a domain
  • Only allowed by the owner
  • Updating a domain’s records
  • Type (A, CNAME, MX, etc)
  • Value
  • TTL
  • Listing all domains owned by a particular person

How might the logic for this feature set look like?

Initial Implementation

pragma solidity >=0.6.4 <0.7.0;
pragma experimental ABIEncoderV2;

contract DNS {
    struct DomainRecord {
        string _type; // "A", "CNAME", "MX", etc...
        string value;
        uint ttl;
    }

    struct Domain {
        address owner;
        DomainRecord[] records;
    }

    mapping(string => Domain) public domains;

    function claim(string memory name) public {
        address domainOwner = domains[name].owner;
        if (domainOwner == address(0)) {
            domains[name].owner = msg.sender;
            return;
        }
        require(domainOwner == msg.sender, "Domain has already been claimed");
    }

    function updateRecords(string memory name, DomainRecord[] memory records) public {
        claim(name);

        delete domains[name].records;
        uint size = records.length;
        for (uint i = 0; i < size; i++) {
          domains[name].records.push(records[i]);
        }
    }

    function release(string memory name) public {
        require(domains[name].owner == msg.sender, "Sender does not own this domain");
        domains[name].owner = address(0);
    }

    function recordsForName(string memory name) public view
            returns (DomainRecord[] memory recordsForName_)
    {
        recordsForName_ = domains[name].records;
    }
}

[View DNS_v1.sol]

This contract allows users to perform basic actions we associate with domain names: claim them, modify their records, and release them. The data associated with these actions are stored directly in the contract itself. Its deployed address is 0x00000001. We register test.com with our wallet at address 0x99999999 and confirm we do own it:

truffle> let dns = await DNS.deployed()
undefined
truffle> dns.claim("test.com")
{...}
truffle> dns.domains("test.com")
'0x99999999'

Great start. Users start registering domain names in our dapp, but a few weeks later someone points out that release doesn’t clear the records on a domain before giving up ownership. We decide that’s a bug, so we have to update the contract by updating the release method:

 function release(string memory name) public {
     require(domains[name].owner == msg.sender, "Sender does not own this domain");
+    delete domains[name].records; // now it clears records during release
     domains[name].owner = address(0);
 }
