This transaction will reflect the last known state of the channel, which is then recorded for finality. Alice and Bob may have transacted on a dozen occasions, but the Ethereum network records only two transactions—the entry and exit transactions. Beyond improving scalability, rollups offer levels of security similar to Ethereum itself because transactions in rollups are anchored to the L1 chain, which guarantees transaction finality. Blockchain sharding is a scalability improvement that introduces parallel execution of transactions in place of the default sequential execution model Ethereum uses. In sharding, the blockchain is divided into smaller chains that validate and process separate transactions. For this reason, the Ethereum community has ruled out bigger block sizes as a scaling solution.

The total value locked on layer 2 is over $10 billion, according to L2Beats. After the Goerli testnet announcement, Ethereum developers have shifted the Shanghai upgrade to April. This will enable faster and more efficient transactions on the Ethereum network. An attempt by the Ethereum developers to reach a solution for scalability has been made via the Merge and by incorporating various L2 networks. Optimism aims to be the most simple, secure, and fastest L2 blockchain and maintains close ties to the Ethereum community through incentivized liquidity mining campaigns. An emerging technology called zkzk-rollup (e.g. Aztec 2.0) allows confidential transactions within the L2 so that others on the same L2 instance cannot decipher your transactions.

Involved parties ethereum layer 2 scaling solutionstain an off-chain state machine (which is fraud-proof by protocol), and only resume to on-chain consensus when absolutely necessary. Layer 2 scalability engines and solutions like Starkware, Optimism and Arbitrum provide scaling for blockchains so that a growing number of exchanges and platforms are able to use networks like Ethereum. Ethereum 2.0 refers to the Ethereum network’s shift to a more sustainable PoS-based system that supports sharding and other scalability features. This set of improvements will increase the scalability of Ethereum and put it on par with other leading blockchains when it comes to throughput. Ethereum investors can stake their coins to earn rewards in return for their contribution to validation efforts.

What is the Need for Ethereum Layer 2 Solutions?
Sidechains will normally have fewer nodes than the L1 mainchain, which allows them to achieve consensus faster. Layer 2’s increase the speed and reduce the cost of transacting on a blockchain. As we have discovered, the Ethereum Merge will not reduce the network’s reliance on Layer 2 scaling solutions.

Plasma users must wait for confirmations in order to consider their transactions completed and secure. This is because Plasma relies on merkle proofs submitted to the main chain by Plasma validators. In the case of State Channels, the requirement of total consent is the reason of a rapid finality, as all participants have access to the last signed state update. This enables cooperating and available participants to make immediate withdrawals of state from their channels. This technique has a series of smart contracts running on top of a root blockchain. The root network contract processes only a tiny amount of commitments from child blockchains that are able to do an incredibly large amount of computations in most cases.
Because sidechains are independent, the security guarantees provided by the Ethereum L1 are not automatically applied to the protocol in the same way that it is for a payment or state channel. Optimistic rollups submit transaction data to the Ethereum network and leverage a dispute resolution system for detecting fraudulent transactions to ensure that all submitted transactions are valid. To close out the channel, a user can submit the latest state update (i.e the final balance of both users accounts) to the L1, which validates this entry as a single transaction on the blockchain. A layer 0 is a type of protocol that enables developers to launch multiple layer 1 blockchains that are connected to the L0 mainchain, but operate independently. Fortunately, layer 2 solutions have emerged to address Ethereum’s scalability challenges, reducing the gas fee burden on users and increasing throughput. At Truffle, our goal is to make building on Ethereum and other EVM-compatible blockchains and L2 networks as seamless as possible by providing the necessary tools developers need to build dapps.
This creates a bidding war of sorts between Ethereum users and forces astronomical increases in transaction fees. However, the block size limit of 1MB reduces the transaction data miners can fit into one block, affecting network throughput. Small block sizes also affect the cost of gas, the computational resource required to execute operations in the Ethereum Virtual Machine. Ethereum has low throughput and slow processing speeds because it prioritizes decentralization and security ahead of scalability . When it comes to ZK rollups, there is minimal hesitation when moving assets from layer 2 to layer 1, considering the validity proof has already been approved by the ZK rollup and has already authorized the transaction.
During its time as Matic, the project scored praise and financial investment from Coinbase Ventures, along with plenty of adoption from smaller projects. The Ethereum network is the main or primary chain, meaning all transactions happening on the network are on-chain. Instead, its transaction throughput is limited to about 15 transactions per second. In addition, Optimism also allows interaction of off-chain codes such as UIs and wallets with layer 2 contracts on Optimism.
The Swap is a Layer 2 scaling solution, specifically an automated market maker type decentralized exchange powered by zkRollup technology. Using the Loopring Pay facility, users can send and receive Ethereum or Ethereum based assets, instantly and for free. The zkRollup scales Ethereum 1000x over its nominal capacity by transferring most processing on another chain. In rollups, numerous transactions are computed off-chain, and then compressed and aggregated into a batch, which contains information about the state.
Aztec https://www.beaxy.com/ is the first private zk-rollup on Ethereum, enabling decentralized applications to access privacy and scale. It scales Ethereum’s tech while also scaling its values through retroactive public goods funding. Optimistic rollups are ‘optimistic’ in the sense that transactions are assumed to be valid, but can be challenged if necessary.
Optimistic Ethereum is an Ethereum Virtual Machine compatible optimistic rollup chain. The main benefits of deployed on Optimism is that it is fast, simple and secure. Users can move assets in and out of the network using Optimistic Ethereum Gateway, and projects looking to deploy can submit a form to get whitelisted by Optimism. Projects that meet their launch criteria will be approved within 2 weeks. On July 2021, Uniswap V3 announced its alpha launch on Optimistic Ethereum mainnet. StarkEx BTC is a layer 2 scalability engine that has been proven and deployed on mainnet since June 2020.
Polygon improves transaction speed and throughput for the Ethereum blockchain via its Matic PoS chain and plasma chains. The implementation of zk-rollups, optimistic rollups, validum chains, stand-alone chains, and shared security chains are in planning. Using off-chain scaling solutions, transactions can be moved from the main chain to a second layer where they can be processed faster and at a lower cost. Most layer 2 solutions use a framework where blockchain transactions and activities are executed independently from the main chain .
- This bottleneck entails elevated transaction costs when network activity is high.
- Therefore the need for scaling solutions has increased in demand as well.
- However, there are layer 2 scaling solutions that aim to improve all these aspects; these solutions are called rollups.
- Other solutions involve the creation of new chains in various forms that derive their security separately from Mainnet, such as sidechains, validiums, or plasma chains.
Whereas sidechains may use other networks or validators to secure the chain, layer 2 differentiates itself by inheriting its security directly from the main chain. The main layer 2 solutions are zero-knowledge rollups and optimistic rollups. After bridging their assets to layer 2 blockchains via their cryptocurrency wallet of choice, users can interact with a wide range of permissionless dApps and DeFi protocols. The number of Layer 2 transactions has recently surpassed the number of Layer 1 transactions for the first time.

Like other layer 2 solutions, it takes transaction bundles from the main chain to be dealt with off-chain before transferring that information back. The Lightning Network also brings smart contracts to Bitcoin, which is a big improvement to the network overall. Sidechains are in fact something of a hybrid between layer 1 and layer 2 solutions to scaling. A sidechain is another blockchain that is linked to a main chain such as Bitcoin’s. They are linked with a two-way peg that is a protocol that allows for the open transfer of cryptocurrency from the main chain to a layer two chain that requires a degree of third-party trust.
We define layer two as a chain that fully or partially derives its security from layer one Ethereum so that users do not have to rely on the honesty of L2 validators for the security of their funds. It’s worth noting, though, that Plasma Group ceased operating and donated the remaining of its funds to Gitcoin to be used on optimistic rollups. Do not do any computation by default, instead are assumed to be valid by default. Users only submit ‘fraud proofs’’ if they see any mathematically verifiable misbehaviour. As computation is a slow, expensive part of using Ethereum, Optimistic roll-ups can offer up to 10–100x improvements in scalability dependent on the transaction.
A plasma chain is a separate blockchain that is anchored to the main Ethereum chain, and uses fraud proofs to arbitrate disputes. Transactions are rolled up into a single transaction to Mainnet Ethereum, reducing gas fees for users making Ethereum more inclusive and accessible for people everywhere. Sharding is the process of splitting a database horizontally to spread the load. Presently, Polygon offers nearly 900 decentralized applications , ranging from lending, borrowing, and blockchain gaming to NFT marketplaces and gambling. The more we use these DApps, the more valuable MATIC token becomes as Polygon’s native cryptocurrency. Nevertheless, sidechains like Polygon carry greater security risks because they operate as independent blockchains which have a native token for rewarding their own set of validators.
What are the different types of layer 2 solutions?
There are two main layer 2 solutions: Zero-knowledge rollups and optimistic rollups.
Doesn’t widely support EVM computation, although a few EVM-compatible ZK-rollups have appeared. The second layer of economic mechanisms can extend the utility of Ethereum, allowing secure interactions that happen off-chain but can still reliably refer back to that kernel if necessary. Offchain Labs, the company behind Arbitrum, rolled out Arbitrum One, their Ethereum mainnet beta on Aug. 31, 2021, and announced $120 in series B funding, valuing the firm at $1.2 billion.

- ZK-rollup smart contracts maintain the state of all transactions on layer 2, which can only be updated with validity proof.
- The L1 gas cost to anchor these L2 transactions on L1 is still much lower than the cost to make these transactions directly on L1, so the operator may be able to pay higher transaction fees in order to ensure timely processing.
- However, unlike a more universalist platform like Hermez, Loopring focuses on providing a cheap and super fast ramp for payment DApps, in addition to being a decentralized exchange .
It can validate and execute transactions without relying on any other network. Meanwhile, another leading Ethereum scaling solution,Immutable X also made headlines by partnering with GameStop, the world’s largest video game retailer, to build a first-of-its-kind gaming NFT marketplace. That means decentralized applications can easily port from Ethereum to their network. Considering the high fees and low throughput of Ethereum, it makes sense for users to find alternatives. Loopring is an Ethereum layer 2 solution that utilizes zk-rollups to power decentralized trading and payment processing with high speed for extremely low fees.

Assets are traded and tracked on the blockchain, reducing risk and cutting costs for everyone involved. State Channels are differentiated from Plasma in that any change of state requires explicit consent from all participants. They depend directly on the records and liveness of State Channel participants. These factors make State Channels one of the mostly tightly constrained techniques for improving the performance of blockchain-based applications. Some of the mechanisms being developed in Layer 2 are State Channels, Sidechains and Plasma.

Additionally, interoperable blockchains are a scalable framework that expand the design space of blockchains, meaning more developers could be attracted to build innovative products on interoperable chains. High throughput, low transaction fees, fast finality, and EVM compatibility could mean that ZK-rollups become the standard framework for dapp deployment, merchant payments, and more. The main centralized exchanges, such as Binance (BNB-USD), FTX, and Coinbase , now support withdrawals to some optimistic rollups like Arbitrum and Optimism, allowing users to onboard those frameworks easily. Additionally, user friendly apps like Argent Wallet allow users to onboard ZK-Sync directly and offer interaction with DeFi apps from their mobile app. Each individual solution has its own pros and cons to consider such as throughput, gas fees, security, scalability, and of course functionality.
