This blog series will introduce you to Polygon Edge, a modular framework for creating sovereign Ethereum Virtual Machine-compatible (EVM) blockchains. In this first post, we will cover the basics of the platform, its advantages, and properties that directly benefit the Dogechain project.

TL;DR

• The Web3 will rely on an internet of blockchains, where different protocols interoperate to build a global, decentralized ecosystem.
• Polygon Edge provides the tools for creating EVM-compatible chains.
• It uses a modular framework that developers can customize to fit their particular use case.
• It introduces a trustless and decentralized Ethereum Bridge solution.
• Dogechain uses the Polygon Edge framework to build a sovereign PoS chain that provides Dogecoin with smart contract capability.

Web3 and the Internet of Blockchains

Blockchain has revolutionized almost every industry known to man — finances, logistics, gaming, art, you name it. This was mainly due to Ethereum’s pioneering of smart contract technology which enabled asset tokenization and digital ownership. As a result, we now have access to DeFi and NFTs, opening the path to a new, decentralized form of the internet, commonly called Web3.

Because it was the first of its kind, Ethereum remains the most commonly used smart contract platform. However, this popularity has brought forth its scalability issues for mass usage. As an answer, platforms like Polygon have come forward with scaling solutions that allow developers to deploy scalable dApps with low fees.

Moreover, a wide range of blockchain protocols that try to solve this dilemma has emerged on the market. Competitors like Cosmos, Solana, BNB Chain, and Avalanche, among many others, are trying to disrupt Ethereum’s dominance. But to create a truly viable ecosystem, neither of these layer-1 protocols can function in a silo. They will ultimately need to share data and assets with each other, allowing users to freely transition from one protocol to another.

This has made it clear that the future of Web3 simply cannot rely on a single blockchain. Instead, it will hinge upon a true internet of blockchains of multiple protocols that will interoperate with each other in one way or another.

What Is Polygon Edge?

The Polygon team has understood this new paradigm and created Polygon Edge — a modular and extensible framework for building scalable Ethereum-compatible blockchain networks.

The primary goal of this framework is to allow developers to deploy highly scalable sovereign blockchains. Additionally, it aims to provide them with all the tools needed to plug their protocol into the existing Ethereum/Polygon ecosystem.

To this end, it offers a wide range of modules that developers can customize depending on their needs. Some of these modules include:

• Blockchain and State, 2 interconnected modules that provide the blueprint for the protocol. Among other functionalities, they allow the execution of transactions and run the EVM.
• Consensus, a module that provides devs with IBFT PoA or PoS consensus engines.
• Libp2p, which provides the basis for the underlying network layer.
• Networking (GRPC), which leverages the communications between nodes on the chain.
• JSON RPC, which implements an API layer that allows dApps to communicate with the blockchain.
• TxPool, which pools the transactions from different parts of the system.
• Minimal, which acts as a central hub for all the services that run on Polygon Edge.

This is just a small selection of the modules in this plugin system. Developers can select and harness these for their needs to create standalone chains that fit their particular use case.

What’s more, Polygon Edge introduces a decentralized built-in Ethereum Bridge solution, which allows for cross-chain communication. This allows users to transfer ERC-20 tokens, NFTs, or wrapped native currencies, from any EVM or Substrate compatible network.

What Are the Main Benefits of Polygon Edge?

The first major benefit of Polygon Edge is the EVM compatibility. It allows developers to bring Ethereum smart contracts directly to their proprietary chain. This means that blockchains created with Polygon Edge can be used to deploy dApps, create NFTs or even build blockchain games. And these will remain compatible with Ethereum’s smart contract protocols, opening the path to interoperability with the existing ecosystem.

The JSON-RPC module, for instance, allows users to interact with these blockchains through industry-standard wallets. This streamlines the user experience, as they can store their tokens on apps like Metamask, with proven security and UX.

Polygon Edge also provides portable code using Solidity/Vyper programming language, considered a standard in the industry. Developers can build using widely-adopted Ethereum tooling, libraries, and development tools.

Finally, the customization features of this modular design are what make Polygon Edge shine.

Developers can change core features and customize the consensus engine, providing best-case scenarios for their particular use case. Devs can pick and choose which functions they need and create a sovereign blockchain by building plugins.

How Does Dogechain Use Polygon Edge?

Dogechain is built with Polygon Edge and inherits some incredible properties from this protocol. Worth noting is that the team has opted for the IBFT PoS, which functions on a mechanism of validators that confirm transactions and block creation.

Some of the benefits of using Polygon Edge as the underlying framework for Dogechain include:

• It’s EVM compatible, meaning tokens on the Dogechain are created using the ERC-20 protocol and pluggable into the Ethereum DeFi ecosystem.
• It uses IBFT PoS, which functions on a mechanism of validators confirming transactions and block creation. This consensus engine is both fast and scalable, allowing Dogechain to remain sustainable and eco-friendly even with mass usage.
• It boasts smart contract capability, opening the possibility for Dogecoin holders to pay for gas with $DOGE for dApps deployed on the chain.

To sum up, Dogechain makes good use of the aforementioned Polygon Edge benefits of modularity and scalability. As a result, it provides users with a sustainable and cost-effective solution for imbuing the original Dogecoin with Ethereum smart contract capability.

Dogechain is bringing DeFi & long awaited utility to Dogecoin. Join the family!
