## The Future of Layer 2 Scaling

The layer 2 ecosystem will need some work to carry out the highest potential of Ethereum. Here are some of the things developers may be working on in the future to improve the rollup sphere.

### Modularity Improvements

By applying the principles of modularity to layer 2 blockchains, we can distribute the tasks and computational load of web3 across different components and layers while creating a much more efficient ecosystem that is easier to evolve as needed. Modular blockchains can be specialized for specific tasks, offering greater design adaptability. They are also easier to upgrade, as they can be improved one piece at a time, reducing the risk of disrupting chain operations.

![layers.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/layers_3b929df9af.png)

Source: [Visa’s Monolithic vs. Modular Blockchains](https://usa.visa.com/solutions/crypto/monolithic-vs-modular-blockchain.html#:~:text=Modular%20blockchains%20can%20leverage%20the,Ethereum%20(post%20data%20sharding).)

### Interoperability Upgrades

Interoperability enables the expansion of the layer 2 ecosystem by allowing applications and users alike to leverage the unique strengths and features of different blockchains without the headache that comes from constantly switching between disparate networks, wallets, and gas tokens. Interoperable networks elicit a cross-pollination of ideas and functionalities that fosters innovation and growth, attracting more users and developers to the blockchain space as it becomes easier to use. Composability is the ultimate version of this, as builders integrate different components to create a “stackable” DeFi ecosystem and a thriving financial foundation.

### Security Updates

The Ethereum Layer 2 ecosystem has witnessed significant advancements in security over the past year and continues to evolve with new and improved security measures. In the future, it is likely that these security trends will continue, like enhanced fraud proofs and incentivized participation in the challenge process. This makes it more difficult for fraudulent transactions to go undetected. Zero-knowledge rollups (ZK rollups) are already leveraging more advanced zero-knowledge proofs to achieve stronger security guarantees, and advancements to cross-chain bridges will make all networks more resistant to attacks.

## Ethereum as a Settlement Layer

![Settlement.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/Settlement_62c4de7268.png)

Source: [Grayscale](https://www.grayscale.com/research/reports/layer-2s-paving-the-road-to-scale-ethereum)

Ethereum serves as the settlement layer for most Layer 2 solutions, regardless of whether they are optimistic rollups or zero-knowledge rollups. This means that Layer 2 transactions are ultimately finalized on the Ethereum mainnet, ensuring the security and immutability of the overall network. As Ethereum will only need to verify the batched version of transactions, the computational load of the network is lessened, leading to less congestion and better performance.

Ethereum is now expected to stand as the premier settlement layer for Web3 due to its mature ecosystem, established developer community, and superior decentralization. Its first-mover advantage and widespread adoption have resulted in a rich ecosystem of tools, services, and applications that support the development and deployment of layer 2 rollups. Additionally, Ethereum's strong security track record and ongoing efforts to enhance its scalability through upgrades like sharding further solidify its position as the foundation for Web3 infrastructure.

## Collaboration: The Key to Mainstream Adoption

Contrary to how some view it (as the [Layer 2 Wars](https://www.forbes.com/sites/leeorshimron/2023/08/16/layer-2-wars-heat-up-as-coinbase-launches-base/?sh=70ea35738e9f)), collaboration will be the key to mass adoption of Ethereum Layer 2 scaling solutions. Cross-chain teamwork and agreement on standards will enable the development of more robust, secure, and user-friendly solutions that can meet the needs of a wider range of users and applications. By working together, developers, researchers, enterprises, and community members can share knowledge, resources, and expertise to accelerate the development and adoption of Layer 2 solutions. This collaboration will lead to a more cohesive and interoperable Layer 2 ecosystem that can handle the increasing demand for scalability and efficiency on the Ethereum network and the blockchain industry as a whole.

Core Blockchain: Ankr’s Newest RPC Connection

![testnets.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/testnets_9b25e4fdf8.jpg)


Ethereum has made big strides in driving the network forward this year as the foundation, core developers, and contributors worked to keep momentum from the Merge to Proof-of-Stake. As a part of this progress, there have been some updates to the test networks or “Testnets” that developers use to examine how their projects and decentralized applications function in a safe environment without real funds or consequences at stake.

## What Are Ethereum Testnets?

Ethereum testnets are public blockchain networks that simulate the Ethereum mainnet. They are used by developers to test smart contracts, applications, and network upgrades before deploying them to the mainnet. This helps to prevent errors and ensure that everything is working as expected.

## Importance of Ethereum Testnets for Developers

Ethereum testnets are essential for developers who are building on the Ethereum blockchain. They provide a safe and reliable environment to test new smart contracts, ideas, and developments without risking any funds or actions on the real Ethereum blockchain. Testnets also allow developers to get feedback from other developers and users, which can help them to improve their work before deploying it to the mainnet.

## What Do Ethereum Testnets Do for Developers?

Ethereum testnets allow developers to do the following:

- **Test smart contracts and applications:** Developers can deploy their smart contracts and applications to testnets to see how they work under real-world conditions. This helps to identify and fix any problems before deploying the contracts and applications to the mainnet.
- **Test network upgrades:** Ethereum developers can use testnets to test network upgrades before deploying them to the mainnet. This helps to ensure that the upgrades are working properly and will not cause any problems for users.
- **Get feedback from other developers and users:** Developers can share their work on testnets with other developers and users to get feedback and suggestions. This can help them to improve their work before deploying it to the mainnet.

[![rpc-remote-rpocedure-call-cta.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/rpc_remote_rpocedure_call_cta_d60ee98bfa.png)](https://www.ankr.com/remote-procedure-call/)

## Common Issues Encountered on Ethereum Testnets

Here is a list of common issues developers have with Ethereum testnets and how they can work around them:

**Testnet congestion and slow block times**

Solution: Choose a less congested testnet, such as Goerli or Sepolia. You can also use a local testnet, but this may not be as representative of the mainnet environment.

**Running out of testnet ETH**

Solution: Request free ETH from a testnet faucet. There are several faucets available, including those from the official Ethereum Foundation and third-party providers.

**Testnet resets and data loss**

Solution: Back up your testnet data regularly. You can use a backup tool specifically designed for Ethereum testnets, or you can manually copy your data to a safe location.

**Testnet compatibility issues with new Ethereum releases**

Solution: Use the latest version of the Ethereum client software. You can also check the Ethereum release notes to see if there are any known compatibility issues with your testnet.

**Lack of documentation and support for testnets**

Solution: Consult the Ethereum testnet documentation and community forums. There are also a number of third-party resources available to help developers with testnets.

## Current Ethereum Testnets

The following are the current Ethereum testnets:

### **Ethereum Goerli Testnet:**

The Goerli testnet is a proof-of-authority (PoA) testnet that is primarily used for testing protocol upgrades and staking operations. It is also a good choice for testing smart contracts and applications, but it is important to note that the network may be less stable than other testnets. NOTE: The Goerli testnet will be retired or “deprecated in

### **Ethereum Sepolia Testnet:**

Sepolia is a proof-of-stake (PoS) testnet that is currently the recommended testnet for smart contract and application development. It is more stable than Goerli and is also more representative of the Ethereum mainnet.

### **Ethereum Holešky Testnet:**

The Holešky testnet is the newest Ethereum testnet. It was launched in September 2023 and is intended to replace the Goerli testnet as the primary testnet for staking, infrastructure, and protocol development. The Holešky testnet has a number of advantages over other testnets, including a larger validator set, improved tokenomics, and better stability.

**Source: [GitHub](https://github.com/eth-clients/goerli) (“Holesovice” renamed Holešky)**

**The following are some of the historical Ethereum testnets:**

**Olympic:** The Olympic testnet was launched in 2015 and was the first public Ethereum testnet. It was used to test the early versions of the Ethereum protocol and smart contract platform.

**Morden:** The Morden testnet was launched in 2016 and was a major improvement over the Olympic testnet. It was used to test the first versions of the Ethereum mainnet.

**Ropsten:** The Ropsten testnet was launched in 2016 and was one of the most popular Ethereum testnets for many years. It was used to test and deploy a wide variety of smart contracts and applications.

**Kovan:** The Kovan testnet was launched in 2017 and was another popular Ethereum testnet. It was used to test and deploy smart contracts and applications, as well as to test network upgrades.

**Kiln:** Kiln was a public Ethereum testnet that was designed to simulate the Ethereum mainnet's merge with the Beacon Chain, which was a key step in the transition to proof of stake. The Kiln testnet was successful in simulating the merge, and it provided a valuable environment for developers and node operators to test their applications and infrastructure before the merge took place.

**Rinkeby:** Rinkeby was a Proof-of-Authority testnet that provided efficient transactions and was a popular Ethereum testnet for development, with a host of active developers and projects using it. Rinkeby was deprecated in June 2023, and it will be shut down in Q2/Q3 2023.

## What Are Ethereum Testnet Tokens?

Ethereum testnet tokens are digital tokens that are used on Ethereum testnets. Testnet tokens are not real Ethereum tokens, and they have no real value, but are rather used to simulate real ETH during the various gas and transactions processes. However, they can be used to test smart contracts, decentralized applications (dApps), and other Ethereum-based projects.

There are a number of different Ethereum testnets, and each testnet has its own tokens. Some of the most popular Ethereum testnet tokens include:

- Goerli ETH 
- Sepolia ETH 
- Rinkeby ETH  (deprecated)

To get Ethereum testnet tokens, you can [use a testnet faucet](https://ethereum.org/en/developers/docs/networks/). A faucet is a website or service that gives away free testnet tokens. Once you have some testnet tokens, you can use them to interact with Ethereum testnets in the same way that you would interact with the Ethereum mainnet.

**Here are some of the things you can do with Ethereum testnet tokens:**

- Deploy and test smart contracts
- Deploy and test dApps
- Test changes to the Ethereum protocol
- Benchmark your applications
- Identify and fix performance bottlenecks
- Test your applications with different wallets and browsers
- Get feedback from users

Ethereum testnet tokens are a valuable tool for developers who are building applications on the Ethereum platform. They allow developers to test their projects safely and effectively before deploying them to the mainnet.

Here are some additional benefits of using Ethereum testnet tokens:

- They are free and easy to get.
- They can be used to test a wide range of Ethereum features and functionality.
- They can help developers to identify and fix bugs before their projects are deployed to the mainnet.
- They can help developers to improve the performance and scalability of their projects.
- They can help developers to get feedback from users before their projects are launched to the public.

## Final Thoughts

Ethereum testnets are essential for developers who are building on the Ethereum platform. They provide a safe and reliable environment to test new ideas and developments without risking any real funds. Testnets also allow developers to get feedback from other developers and users, which can help them to improve their work before deploying it to the mainnet. Use Ankr’s Ethereum Testnet endpoints to begin evaluating your smart contracts and projects today.
