How to use Truffle to build on Ethereum Layer 2 networks

At the moment, we currently support 3 Truffle Boxes that focus on rollups and side chains and are working on adding to this collection. Moving on from scalability, the number of problems or issues faced by Ethereum also includes the concerns about the unreasonable gas prices and slower transactions on the layer 1 blockchain. As a result to all the existing issues, Ethereum now have two solutions, or rather options; better NEAR referred to as sharding and layer 2 solutions. Both of the solutions are working towards addressing the problems of scalability, high transaction fees, and delays in transaction settlement. There is no second guessing that one of the most popular blockchain networks that is in use in today’s market is Ethereum.

Layer 2 solutions span general-purpose to application-specific solutions. Some have their own security measures, and some inherit their security from layer 1. However, in essence, they all share the same logic of processing transactions off-chain for scaling purposes. We will focus on Channels and Rollups, which we believe today to be the most potentially transformative solutions. Plasma chains are similar to sidechains, as they connect with the Ethereum blockchain via smart contracts. Using a Plasma chain requires locking up ETH in a smart contract on the root chain before getting tokens on the child chain.

In contrast, decentralized blockchain networks such as Bitcoin or Ethereum can process only around 4 TPS and 30 TPS respectively. Building and running applications on blockchain requires much faster processing speeds, which is where the L2 scaling solutions come in. Bundle hundreds of transactions off-chain into a single transaction and send it to the main chain through validity proofs. This reduces data sizes and, in turn, lowers the gas fees and time for validating blocks. Zk rollups, however, cannot execute smart contracts like Optimistic rollups. Before we begin, a little insight on the overall reason for the efforts put into making the scaling solutions.

Similar to ethereum layer 2 scaling solutions and Optimism, Arbitrum is an Optimistic Rollup for scaling Ethereum smart contracts. In other words, Arbitrum makes Ethereum faster and cheaper to use, specifically for developers. Below, you’ll find the best Layer 2 scaling solutions ranked in order of network activity. Ethereum is a generalized public blockchain anyone can use to build decentralized apps, launch tokens, and spend digital currency. Its comprehensive capabilities make it a highly accessible virtual computer, which is probably why Ethereum does over 1 million transactions per day. The most striking highlight of Parastate refers to EWASM, which is basically a WebAssembly variant of EVM.

This layer 2 scalability network does the job as good as Immutable X, making NFT trading super affordable. Without going into cryptography minutia, this means that transactions are verified without other parties revealing their identity. The ZK approach also results in greater data throughput because its type of rollup significantly reduces transaction volume. Yet, much is expected of Arbitrum because it has its own Arbitrum Virtual Machine. At first glance, this may seem like a problem, but it is a benefit because it doesn’t rely on Ethereum if it significantly changes its consensus protocol.

• Payment channels were the first type of state channel to be described, using off-chain transactions to modify ownership of locked Bitcoin, allowing users to make “off-chain payments” between each other.
• The Bitcoin lightning network also claims that it is capable of processing millions to billions of TPS, which is many times higher than legacy payment providers like Visa.
• The protocol has settled over $250 billion worth of transactions in the past six months.
• DApps then run via these smaller mini blockchains, greatly lowering the strain on the main network.
• The network is home to big industry names like Consensys, Sushi, and Uniswap.
• It supports incredible scalability at 10,000 TPS, lower fees, less energy usage and lower processing times.

Reduced transaction fees by bundling a handful of transactions into a single transaction before sending them to the mainnet means way less transaction fees. Arbitrum is one of the most mature L2 ecosystems and has a wide variety of active DeFi applications. Arbitrum is an optimistic rollup with transaction fees ranging from $0.02 – $0.07 on average.

However, general-purpose ZK-rollups, which many experts thought would take longer to develop, are now market ready. The best example of a payment channel today is the Bitcoin Lightning Network, which can process up to 100,000 TPS with almost zero fees. As a result of limited throughput and increasing demand, Ethereum’s transaction costs have increased.

Anything that you can do on ethereum layer 2 scaling solutions layer 1, you can also do on layer 2. Many dapps have already begun to migrate to these networks or have skipped Mainnet altogether to deploy straight on a layer 2. Not all solutions require utilizing the Ethereum consensus algorithm directly, and alternatives can offer benefits that would otherwise be difficult to obtain. Multiple solutions can help reduce the overall congestion on any one part of the network, and also prevents single points of failure.

Put simply, aggregators publish minimal information on https://www.beaxy.com/-1 and assume that the data is correct. Currently, Ethereum is one of the most sophisticated blockchains in terms of network security and stability. The majority of individuals and companies opt to use this blockchain for transactions or to build projects.

In the case of a fraudulent transaction, the optimistic rollup performs a fraud-proof and penalises the sender. With Layer-2, the underlying network does not need to process such large amounts of data because it sends this data to different processing channels , recording only the final result on the Layer-1 blockchain.

What Are Layer-2 Scaling Solutions

At the moment, most ZK-rollups are application specific, in contrast with optimistic rollups which have largely been generalizable. The primary difference is what data is posted to the layer 1 and how the data is verified. Validity proofs (used by zero-knowledge rollups) run the computations off-chain and post a proof, whereas fault proofs only run the computations on-chain when fault is suspected and must be checked. Layer 2 projects will post their transaction data onto Ethereum, relying on Ethereum for data availability. This data can be used to get the state of the layer 2, or to dispute transactions on layer 2. Different solutions can exist and work in harmony, allowing for an exponential effect on future transaction speed and throughput.

However, this leaves the tendency for network division and security issues. Greater transaction throughput because L2s perform computations outside Ethereum (off-chain) and only have to post compressed transaction data to the mainnet, thus transaction speed is significantly improved. In decentralized networks, the “Scalability Trilemma“ refers to the idea that a network cannot be decentralized, secure, and scalable at the same time. The Trilemma states that for a blockchain network to exist, it would have to make a tradeoff, leaving out one of these three aspects. This is why today, there are a myriad of blockchain layer 1 like Solana and NEAR and layer 2 chains like Arbitrum, Polygon, and Optimism to choose from. Each promises its own set of advantages and disadvantages, depending on which aspects of the Scalability Trilemma it chooses to solve.

• The only caveat is that both must sign transactions, which means Alice and Bob must approve each payment for coffee.
• Each with its own mechanism for block validation, Plasma chains periodically report back to the Ethereum main chain, using its security to settle disputes when challenged via fraud proofs.
• And as on-chain activities increase, the network becomes congested, drastically reducing transaction speed.
• As the first sidechain specialized in NFT trading, Immutable X doesn’t charge any gas fees and provides an amazing transaction speed of up to 9,000 TPS with instant confirmation.

Layer 2s are built on top of the Ethereum blockchain, keeping transactions secure, speedy, and scalable. State channels improve blockchain performance by moving state-modifying operations off-chain. Payment channels were the first type of state channel to be described, using off-chain transactions to modify ownership of locked Bitcoin, allowing users to make “off-chain payments” between each other. The term “state channels” generalizes this technique beyond payments, including all types of blockchain state modifications.
