What Is an Ethereum Layer 2 Project?
Layer 2 networks were created as a response to Ethereum — a layer 1 crypto — having too low throughput to support the amount of traffic on its network. Scaling solutions built on top of Ethereum’s layer 1 blockchain process transactions independently and only do final verifications on the main blockchain. While the most common types of layer 2 networks are sidechains and rollups, there are different shapes and flavors of scaling solutions, including:
- Rollups (zkRollups and optimistic rollups)
- Sidechains
- State/payment channels
- Plasma chains
- Validiums (zkSNARKs and zkSTARKs)
Let’s look at each type of Ethereum layer 2s individually and examine their inner workings.
Rollups
As mentioned, there are two types of rollups: optimistic rollups and zero knowledge rollups (zkRollups). While they differ in centralization, finality, and data storage, their basic principle works similarly.
The rollups bundle hundreds of separate transactions and report them to layer 1 in a single transaction. As such, the fees accrued only amount to one transaction, making transacting on a rollup a fraction of the cost of one on a layer 1.
While rollup transactions are computed on a separate blockchain, they are reported to and stored on the main chain for finality. As a result, rollups are guaranteed the same security as the main chain because altering a final transaction on the rollup chain would also mean changing the transaction on the main chain.
Optimistic Rollups
Optimistic rollups work under the assumption that all transactions are valid by default — hence the name “optimistic.” In order to spot a potential invalid transaction, they employ a fraud-protection method based on validators reporting the transaction during a specific time frame. This means that they require at least one honest validator at all times.
The most notable optimistic rollup layer 2s include Optimism and Arbitrum.
Pros
- Easy-to-implement EVM-compatibility
- Low hardware costs
Cons
- Difficult to maintain privacy
- Reliance on honest validators
- Slow fund withdrawal period in the case of an invalid transaction
zkRollups
Unlike optimistic rollups, zkRollups don’t have to work under any assumptions. Instead, they use a cryptographic method called zero-knowledge proofs to verify transactions without exposing the identity of the participants or the contents of the transaction. While this increases the network’s security, it also increases its operating costs and complexity.
The most notable zkRollup layer 2s include zkEVM, zkSync, and Starknet.
Pros
- High throughput
- Quick fund withdrawal in case of an invalid transaction
Cons
- Hardware-intensive
- Difficult EVM-compatibility implementation due to code adjustment requirements
Sidechains
Sidechains work differently from rollups in that they maintain their own network state using their own consensus mechanism. As such, they do not benefit from layer one security the same way rollups do, but this comes with the advantage of not storing data on layer 1.
Instead of reporting transactions to layer 1, sidechains run in parallel with layer one, using bridges to transfer assets between the chains. Sidechains are becoming less used as the emergence of rollups grows.
The most well-known sidechain is Polygon, although, as we discussed earlier, it has recently launched a zkRollup chain, zkEVM.
Pros
- Higher throughput than most rollups
- Lower fees (mainly data storage fees and zk proof fees)
- Instant finality
Cons
- Less secure than rollups
- While great as a transitional layer 2, it lacks the “complete package” rollups are aiming for
State/Payment Channels
State or payment channels are peer-to-peer networks that enable two parties to transact among themselves. When looking at their core components, they are most similar to Bitcoin’s Lightning Network. The channels work like IoUs, only submitting the final results to the main blockchain.
These channels’ core purpose is to facilitate micropayments or frequent payments between two parties, as regular on-chain transactions would simply cost too much. On top of that, main chains like Ethereum’s blockchain take time to settle transactions, and that may not be optimal for parties that need to transact often and quickly.
Pros
- Instant finality
- Throughput is not limited by blockchain
- Completely private
- Cheap to operate
Cons
- Parties’ funds need to be locked up in order to transact
- Parties need to trust each other
- Data is less protected than on a blockchain
- New channels require modifications to user wallets
Plasma Chains
Often referred to as a “child” of Ethereum, plasma chains are, in essence, small copies of Ethereum mainnet.
The architecture works by creating root contracts as an element of each of the plasma side chains. This root contract links the child chains to the main chains while establishing a set of rules that guides each of the plasma chains. One thing to note is that plasma is still an under-tested and under-used system, though developers are coming out with new upgrades very quickly.
Pros
- Low transaction costs
- High throughput
- Users can create personalized plasma chains
Cons
- Lax security systems
- Network congestion in certain circumstances
- 7-14-day delays in fund withdrawals are possible
Validiums (zkSNARKs and zkSTARKs)
Validiums are another form of scaling solution that uses off-chain computation in terms of zero-knowledge proofs. Once they finish computing a transaction, they publish proofs directly on Ethereum to verify it.
Validity proofs submitted to Ethereum can come in the form of zkSNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) and zkSTARKs (Zero-Knowledge Scalable Transparent Argument of Knowledge).
Validiums are great for certain use cases, such as blockchain gaming or trading, as they require privacy and scalability equally. However, as with all technologies that use zero-knowledge proofs, they suffer from high hardware costs.
Pros
- High scalability
- Reduced gas fees
- Guaranteed off-chain data validity
Cons
- High hardware costs
- Slow finality time
- Limited support for smart contract integration
Why Invest in Ethereum Layer 2 Blockchain Coins?
As we saw with the Polygon MATIC price in the last bull run, helping solve the scalability issue in crypto can be a very lucrative use case. With that in mind, here are the reasons to buy layer 2 coins.
Improved Scalability and Efficiency
Ethereum’s network currently processes approximately 600 transactions every 12 seconds, putting its throughput at ~50 tp/s. While this number doesn’t seem like much, this number was achieved only after the recent Dencun upgrade. Prior to that, Ethereum handled 15 to 30 transactions per second.
On the other hand, its scaling solutions not only handle more transactions per second on average; they also reduce the necessity of many transactions to be handled directly on Ethereum, making it a win-win situation for the second-largest cryptocurrency by market cap.
Growing Demand and Adoption
Cryptocurrencies as an investment vehicle and development ecosystem are becoming more popular as time passes. This is especially true after the introduction of Bitcoin and Ethereum ETFs, where crypto has de-facto become mainstream.
With increased adoption comes increased demand; with increased demand comes more transactions and more scalability problems. This is where layer 2 scaling solutions step in and provide a much-needed fix.
Reduced Gas Fees
Layer 2 scaling solutions are created — as their name suggests — to improve scaling. This means higher throughput, as well as lower gas fees.
When comparing an uncongested mainnet to an uncongested layer 2 network, gas fees are often not too different. However, we’ve all seen peak Ethereum mainnet congestion gas fees that reached hundreds of dollars in 2021.
In order to avoid getting caught in such congestion, it’s smart to consider having layer 2 networks in your arsenal.
High Upside Potential
While Bitcoin and Ethereum sit at market caps well over $100 billion, the largest layer 2 by market cap is Polygon, which is at just over $5 billion. Furthermore, many layer 2’s on our list have less than $1 billion market caps.
Although they could present a higher risk, low market cap layer 2s could provide vastly more upside potential than well-established coins like Bitcoin or Ethereum. Therefore, if you are looking for a layer 2 crypto with the most upside, you might want to check smaller market cap projects.
What Is the Best Ethereum Layer 2 Coin?
Deciding which layer 2 to invest in can be overwhelming. However, we have broken down the main things worth considering below.
Market Cap
As with any asset class, market cap plays an impactful role in the potential of a crypto. Each project has a ceiling based on the market’s liquidity and the individual project’s importance.
Therefore, understanding a project’s significance and comparing it to its market cap is a great way to decide which tokens are best to buy.
Network Effect
The best way to determine a project’s significance is to understand its network effect. This comes down to considering factors like its daily active users, daily revenue, number of protocols (and success of protocols), number of developers and total value locked on the chain.
A chain that scores high for each but has a relatively low market cap may fare a better investment.
Tokenomics
It is also essential to consider tokenomics. Factors like the level of utility that the token provides, the circulating supply, and the vesting schedule all play a significant role in the success of a project.
Technology
It’s important to consider the technology behind the layer 2 project. Some scaling solutions use groundbreaking technology with more potential, while others use older and safer systems.
While it takes a high degree of technical expertise to understand the intricacies of each technology segment, it’s worth looking into expert opinions and looking for potential system vulnerabilities before dedicating any amount of funds to a singular layer 2 project.
Conclusion
Ethereum layer 2s are some of the most high-potential cryptos on the market today. However, after thoroughly examining the best Ethereum layer 2 projects, we found that Pepe Unchained ($PEPU) could be the best one in the market today.
This Pepe-themed meme token is built on Ethereum’s L2 chain, and offers high staking rewards, low transaction costs, and fast transaction speeds. Currently, $PEPU is available to purchase on presale.
