Introduction

A long time ago, communication was not as strong as it is now. it takes a lot of time before it gets to the receiver, at times it may warrant either the sender to travel down to see the receiver to deliver the message or it may take time before the message gets to the receiver. This is similar to one of the challenges blockchain technology was facing, Transferring assets or data between different blockchain networks was time-consuming and often required complex manual processes. For example, if a user wanted to transfer a cryptocurrency token from one blockchain to another, they often had to go through lengthy and cumbersome procedures, akin to the sender having to travel to deliver a message in person.

How can this problem be solved? With the advent of interoperability protocols and cross-chain solutions, blockchain communication evolved seamlessly, just like the way our modern communication technologies make it easy to message instantly and globally.

With this innovation, comes WORMHOLE an interoperability protocol that allows developers to build cross-chain applications effortlessly. In this article, we will explore what Wormhole is, its importance, features, supported blockchain, programming languages, Wormhole SDKs and their uses, quick tutorials, and proposed product ideas.

Why Wormhole

In this phase, we will be diving into what Wormhole is and its importance to product development. As earlier said Wormhole is an interoperability protocol, designed to facilitate communication and transfer of digital assets between multiple blockchains. It serves as a "bridge" that enables different blockchain networks like Ethereum, Binance Smart Chain, Terra, Solana, Polygon, Avalanche, and Oasis to interact with each other. With Wormhole, developers can write a single smart contract for their Decentralized Applications (DApps) which interact seamlessly with multiple blockchain networks.

The good thing about Wormhole is that it is developer-friendly, i.e. it is easy to integrate with and offers security. It enables developers to deploy their smart contracts on multiple chains, synchronize data across chains, and transfer assets easily between chains. Wormhole also supports cross-chain communication, allowing applications to interact with each other across different chains. This protocol can save time and reduce the risk of errors when dealing with complex code.

A pictorial diagram demonstrating how a wormhole works is presented by Wormhole. 👇

From this diagram above, this is an illustration that shows the communication between two chains. The source Chain is the sender while the target chain is the receiver.

Some Multi-chain apps built with Wormhole are Allbridge, C3, Carrier, Hashflow, Synonym, Portal e.t.c

Features of Wormhole

It is important to note some of the features of wormhole, they are :

1. Access to Multiple Blockchains: Developers can now access liquidity and users on over 20 leading blockchain networks via Wormhole. This enables use cases across DeFi, NFTs, governance and other areas, and allows developers to take advantage of multiple ecosystems for their applications.

2. Cross-Chain Messaging Protocol: Wormhole is a protocol that allows communication between blockchains and enables developers to send arbitrary data cross-chain, including tokens, NFTs, oracle data, governance decisions, and more.

3. Wormhole Connect: Wormhole Connect is a valuable asset layer product that offers developers an in-app bridging widget. It can be easily integrated using as few as three lines of code. This feature allows developers to create applications that can interact with multiple blockchains without any bother.

4. Potential Applications: Wormholes have a variety of applications, including cross-chain exchanges, governance, and games.

5. Open Source: Wormhole is an open-source blockchain development platform, which means developers can review, modify, and enhance the source code to suit their needs.

6. Wormhole Queries: is a new feature that allows users to access on-chain data across different blockchains on-demand. Unlike most interoperability protocols that use a "push" model, Wormhole introduces a "pull" mechanism for data retrieval, making cross-chain data access faster and more cost-effective.

7. Wormhole Explorer: Users can explore in-depth details about messages, and view daily and monthly bridged messages between the different chains both on Mainnet and Testnet. Check this video below👇

   

Note that Wormhole is not a blockchain itself neither it isnt a token bridge even though there are protocol builts on wormhole that enables this purpose.

Wormhole Supported Blockchains

Some of the supported blockchain wormhole interacted with are: Acala, Algorand, Aptos, Arbitrum, Aurora, Avalanche (C-Chain), Base, BNB Chain, Celo, Cosmos, Ethereum, Fantom, HydraDX, Injective, Karura, Klaytn Moonbeam, Near, Oasis (Emerald), Optimism, Osmosis, Polygon, Polkadot, Solana, Sei, Sui, Terra 2.0, Terra Classic, XPLA

Programming that works with Wormhole

1. JavaScript: is a versatile language that can be used for both frontend and backend development. It's widely used in web development and is supported by Wormhole.

2. Solidity: is a statically typed programming language designed for developing smart contracts that run on the Ethereum Virtual Machine (EVM). While it's primarily used for backend blockchain development, it can be used in conjunction with frontend frameworks to interact with smart contracts.

3. Vyper: is a contract-oriented programming language for Ethereum. Similar to Solidity, it's used for backend blockchain development but can interact with frontend JavaScript frameworks.

4. Rust: is a multi-paradigm programming language designed for performance and safety. While it's primarily used for system-level programming, it can be compiled into WebAssembly for use in web development.

5. Go: is a statically typed, compiled language that is simple and efficient. It's primarily used for backend development but can be compiled into JavaScript or WebAssembly for use in frontend development.

6. Move: is a new programming language for implementing custom transaction logic and smart contracts in the Diem Blockchain. It's primarily used for backend blockchain development.

Wormhole SDKs

What is SDK? SDK stands for Software Development Kit. It's a collection of software tools and libraries that developers use to create applications for specific platforms. An SDK provides a set of tools, libraries, relevant documentation, code samples, processes, and guides that developers can use and integrate into their apps. some of Wormhole SDKS include:

1. ConnectSDK: This is a TypeScript SDK for interacting with the chains Wormhole supports and the protocols built on top of Wormhole. It's a work in progress. It can be used to get a ChainContext object for a specific chain, fetch balances, get a TokenBridge client for srcChain, and grab a Remote Procedure Call (RPC) client. For example, you can use it to create an app that showcases users' balances, just by inputting their wallet address.

2. Wormhole Solidity SDK: This SDK helps developers make cross-chain development with Wormhole easier. It specifically provides the TokenSender and TokenReceiver abstract classes with useful functionality for sending and receiving tokens using TokenBridge. This can also be used to write smart contracts for validating transactions across multi-chain platforms.

3. Wormhole cross-chain queries SDK: This SDK is used for making cross-chain queries in Wormhole.

4. Wormhole Spy SDK: This SDK allows you to listen to all of the activity on the Guardian Network. For example, it can be used to monitor network activity, for debugging or tracking specific transactions in a nutshell, it can be likened to CCTV cameras in local banks.
