Just like other blockchain platforms, Ethereum has the potential to build a decentralized future. Achieving this requires more than cryptography, tokenomics, institutional adoption, or regulation. We need to construct the infrastructure that will facilitate the processes. We need utilities that reduce barriers to entry and simplify access to Ethereum data across the network. Infrastructure-as-a-Service (IaaS) solutions are crucial in this regard.
Infura is a leading provider in this field and is a credible solution to these needs. Self-styled “the world’s most powerful suite of high availability blockchain APIs and developer tools”, Infura offers a range of tools for decentralized apps (dApp) teams, developers, and enterprises from various industries to connect their applications to the Ethereum network and other decentralized platforms.
This article provides an in-depth exploration of Infura, its pivotal role in the Ethereum blockchain ecosystem, as well as what the future may hold for this vital platform
- Ethereum is widely recognized as the most popular blockchain and is used by most developers to deploy their blockchain-based applications for use throughout the world.
- However, to integrate their dApps with the Ethereum blockchain, developers must run a node, which can be both time-consuming and expensive.
- Developers can connect to the Ethereum blockchain through Infura’s managed nodes, which are called “node services.” This saves developers the trouble of setting up and maintaining their own nodes.
- Infura works with the Ethereum blockchain to run nodes on behalf of its users, thereby allowing the Ethereum ecosystem to thrive.
What is Infura?
Infura is a Web3 platform that provides a suite of tools that allow developers to build applications that easily connect to the Ethereum blockchain. It acts as an intermediary between its users and the Ethereum blockchain by managing nodes on their behalf.
Blockchains are systems that facilitate the movement of value; however, the types of transactions we carry out require a more sophisticated system that allows for adding conditions to transactions. The Ethereum blockchain solved this problem in 2015 when it introduced the concept of smart contracts.
Ethereum became a blockchain that could be programmed for any value-related purpose, and as such, it quickly became the backbone of the growing Web3 space. Smart contracts enabled it to transfer value and handle complex interactions. Developers could use the blockchain to build their applications on its ledger infrastructure, leading to the growth of a whole ecosystem of DeFi, utility platforms, and NFT exchanges around Ethereum.
However, to interact with Ethereum’s smart contracts, a special node needs to be run (which can be costly, time-consuming, and difficult to maintain). This feature made building on the Ethereum blockchain difficult for developers.
Infura was developed to solve that problem. It allows developers to outsource the running of nodes, enabling them to focus on their project while someone else handles the node maintenance. Infura’s “nodes-as-a-service” makes it easier for developers to launch their app on Ethereum without the need to build and maintain their own node.
Networks on Infura
Many blockchain networks rely on Infura to provide solutions and options for developers to build decentralized applications and interact with other blockchain technologies. A few of the networks on Infura are listed below:
Ethereum
It is a decentralized, open-source blockchain network that supports Turing-complete smart contracts. The native cryptocurrency is ether (i.e., ETH). As of mid-September 2022, Ethereum uses the proof-of-stake consensus mechanism. Infura provides access to the Ethereum JSON-RPC API library, which enables interaction with the Ethereum blockchain.
Arbitrum
Arbitrum is a scaling solution for Ethereum that allows smart contracts to run quickly and cheaply. It is EVM-compliant, and developers can connect using the node API. Arbitrum nodes are compatible with Ethereum’s JSON-RPC API implementation, allowing them to be used with tools such as MetaMask, Truffle, and Infura.
Aurora
Aurora is based on the NEAR protocol and gives developers the same experience as Ethereum but with the scalability and speed of layer-2 blockchains.
Aurora supports all Ethereum ecosystem tools, including Truffle, MetaMask, Remix, and Hardhat. Furthermore, due to NEAR’s trustless bridge to Ethereum, the assets on Aurora are identical to those on Ethereum. For example, account balances in Aurora’s EVM are denominated in ether (ETH).
Avalanche (C-Chain)
Avalanche is a layer-1 proof-of-stake platform with three built-in blockchains: the contract chain (c-chain), exchange chain (x-chain), and platform chain (p-chain).
The C-Chain supports EVM (Ethereum Virtual Machine), thus enabling Ethereum developers to deploy Solidity smart contract dApps on the C-Chain. Avalanche and Ethereum both support dApps.
Other networks on Infura include:
- Celo
- Filecoin
- IPFS
- Near
- Optimism
- Palm
- Polygon PoS
- StarkNet
- Eloper
Why Infura Is the Secret Weapon of Ethereum Infrastructure
It facilitates access to Web3.
Infura plays a critical role in enabling Web3 projects to access Ethereum by offering APIs that connect their applications to the blockchain network. Some notable Web3 projects, such as OpenZeppelin, Aragon, MetaMask, and Gnosis, use Infura’s infrastructure to handle both short-term spikes and long-term scaling solutions.
Infura simplifies the Ethereum development process for all developers by providing essential tools to start building applications without managing the complex infrastructure itself. This is beneficial for developers testing on networks like Rinkeby, Kovan, or Ropsten with no traffic, as well as those testing on the mainnet with high traffic.
Infura’s suite provides all of the speed, features, and reliability that your application requires
Infura’s most widely used aspect is its network of hosted Ethereum clients that connect to both the mainnet and testnets. These clients use JSON-RPC over HTTPS and WSS, making them compatible with various client applications.
But Infura goes beyond just Ethereum nodes – it also offers one of the first public IPFS APIs and gateways, establishing the foundation of its Web3 development suite. Infura’s modular scaling solutions unlock critical network capacity for high-traffic dApps that struggle with temporary or permanent local infrastructure, such as ICOs and CryptoKitties.
Some projects, such as Gnosis, use a hybrid approach that allows them to verify their transactions while lowering infrastructure costs and increasing network stability. In cases where scale is critical, such as CryptoKitties, Infura collaborated with developers from across the ecosystem to keep the network running smoothly.
The Limitations of Infura
Although Infura is developing high-quality tools and resources to reduce the barrier to entry for crypto and blockchain and help developers, institutions, and businesses to create dApps quickly and easily, it has some limitations.
Since Infura processes over 10 billion queries daily, it is difficult to achieve the transaction speed and volume that are possible with a private node. Let’s consider Infura and MetaMask’s relationship and explain how this plays out.
MetaMask has always relied on Infura as its endpoint provider because of its industry reputation for dependability and accessibility. However, as blockchain usage increases, it is essential for MetaMask users to be able to submit requests to the blockchain, regardless of their location or intended actions on the chain, even if other users are doing the same.
It is important to note that there are limitations to this. On-chain activity increases, the network becomes more congested, and gas fees may be affected. In addition, there is a limited number of transactions that can be included in each block.
Infura’s traffic capacity becomes crucial in this scenario, as they provide endpoints for multiple blockchains, not just Ethereum. With the rise of multiple blockchains in the future, reliable support for multiple chains through Infura will be vital.
In a nutshell, Infura solved a significant issue for Web3 developers by providing nodes as a service. Although the dApps themselves remained decentralized, Infura became a central point of failure for the ecosystem.
Is Infura a Return to Centralization?
The central tenet of Web3 is decentralization, which is why any platform or system that relies on one central entity creates a significant power imbalance. Such an entity can shut down the entire system if it so chooses.
Since Infura is the node provider for a large number of dApps, any problems with Infura pose a threat to the entire system. Two clear issues come to mind in this regard:
- Outages: We have already witnessed this problem. Infura outages have caused significant portions of the Ethereum dApp ecosystem to go down at the same time. Several platforms, including MetaMask and Binance, had to shut down functions that relied on Ethereum or tokens based on Ethereum. If you used either of those platforms as a wallet, you had less control over your crypto.
- Censorship: As a centralized service, Infura can be monitored and censored by governments or third parties. This goes against the core principles of a decentralized space and undermines the unique feature that distinguishes Web3.
Infura’s Plans for the Future
In 2022, Infura announced plans to launch a decentralized infrastructure network in the first half of 2023. This network will provide an open-source ecosystem of infrastructure providers who will work together to overcome the limitations of the current services.
The decentralized protocol will demonstrate the potential of Web3 technology by ensuring that millions of future users can access the data and services they require without any downtime or interruptions due to a single point of failure. This could make ecosystems more resilient and help them work together better.
The decentralized protocol aims to create a strong community of infrastructure operators who can handle high-throughput requests like a multi-cloud database without a single point of failure. It also aims to ensure the long-term viability of Web3 via scalable communal governance and data sovereignty, satisfying the requirements of digital-native consumers while promoting security, ownership, and transparency.
