Rollups – An Overview

Rollups are the answer to scaling blockchain throughput and minimizing transaction fees. Layer 1 chains like Ethereum have had trouble with achieving increased transaction rates. Simply put, Ethereum is the largest dApp ecosystem out there. It processes thousands of transactions daily, but its limited throughput causes network congestion, leading to high gas fees.

Layer 2 scaling solutions emerged to tackle these woes, taking transactions off the main chain, validating them off-chain, bundling them into compressed packages, and sending them to layer 1, or Ethereum, for finality. This breakthrough presented a new avenue for blockchain technology, allowing projects and users to harness the scalability and efficiency provided by layer 2 networks while still relying on the security of layer 1 blockchains.

The same technologies are integrated by layer 3 solutions that offer scalability and efficiency beyond what layer 2s can. Layer 3 RaaS platforms implement optimistic and ZK-rollups -- the two kinds of rollups.

The 3Base Unifier is a layer integrating modular setups to achieve settlement on the Base blockchain effectively. It rolls up to Base by processing optimistic rollups (and ZK rollups in the future) from the layer 3 execution environment and handling data from the chosen DA Layer and network states from the Base settlement layer.

Unifier Setup

Validation – 3Base allows anyone to set up nodes based on staking criteria to ensure the integrity of the layer 3 ecosystem via decentralized consensus mechanisms.

Proof-of-Stake – Layer 3 chains are validated using the PoS consensus mechanism to maintain high scalability and robust security.

Functionalities of the Unifier

Secure bridging – 3Base implements highly secure bridging, securely communicating transactions and other data between layer 3 app chains and Base.

Tooling – Integrates and amalgamates 3Base’s tooling functionalities with the modular setup.

Rollup Verification Layer – Verifies claims of fraudulent transactions when fraud proofs are issued to reverse states in case of illegitimate transactions to maintain integrity while settling on Base.

3Base is a Layer 3 scaling solution, built atop Coinbase’s Base chain, designed to aid building dApps in a lightning-quick and seamless manner. While Layer 2 rollups already offer significant improvements in scalability and transaction throughput compared to the base layer of a blockchain (like Ethereum), 3Base being a Layer 3 rollup leverages the true potential of layer 3 solutions offering further advantages like cross-rollup communication, enhanced scalability, complex functionality execution and improved security.

It’s as simple as that. You’ve deployed your first rollup if you followed those steps. Yay!

Leveraging Base’s capabilities to the fullest requires integrating and building various elements working in tandem to offer a powerful, comprehensive rollup experience from a single layer 3 solution.

Interoperability Protocols – The multi-chain vision grew as layer 2s gained prominence. Layer 3s will be responsible for fully interoperable multi-chain and omni-chain ecosystems, reducing the barriers to building dApp infrastructures across networks and unifying their operations.

Cross-Chain Communication – An interoperable experience will only exist when messages can be relayed and assets transacted across layer 2 ecosystems, fostered by layer 3 platforms.

Advanced Smart Contracts – With new horizons unlocked by layer 3s, builders can implement complex contracts to serve needs that were not possible in the decentralized realm. Now, they can rely on efficiency and interoperability to address niche market requirements.

Improved Privacy and Security – dApps leveraging layer 3 rollups can easily turn to Zero-Knowledge Proofs (ZKPs) and secure Multi-Party Computation (sMPC) protocols to traverse the blockchain ecosystem and interact with value safely.

Synchronized Transaction Settlements – Layer 3s operating in the multi-chain ecosystem must bundle transactions from various layer 2 rollup solutions and relay them to layer 1 networks for final settlements.

Another form of rollups, ZK (zero knowledge)-rollups work differently than their optimistic counterparts. Validators on networks using this rollup verify all transactions are valid before relaying transaction bundles to the layers above. Essentially, ZK-rollups utilize ZK-proofs to attest to transaction validity.

This process involves validating transactions using privacy-enhancing technologies – validators on ZK-rollup protocols can verify transactions without knowing the details of said transactions, including amounts transferred or wallet addresses. Using ZK-related technology on these networks makes them attractive to users looking for privacy features.

Moreover, no challenge period exists since these solutions verify transactions before relaying them to other layers. Users can move their funds to layer 1s and withdraw them immediately. Still, ZK-rollups have their problems, mainly the increased computational power needed to generate ZK-proofs.

These rollup solutions assume all transactions are valid – therefore optimistic. Thus, network operators create blocks containing the transactions occurring on the network and roll them up to the layer above. Layer 2s roll-up transactions to layer 1s, and layer 3s roll-up transactions to layer 2s. Regardless, a layer 3 still benefits from the security of the layer 1 that the layer 2 is associated with.

Optimistic rollups come with a challenge period, usually seven days, during which network validators can issue fraud proofs to transactions they feel are invalid. Since these rollups send transaction bundles by assuming all the transactions within them are valid, fraud proofs are necessary to maintain network integrity.

If on-chain computations reveal that the transaction was fraudulent, the states of the wallets involved in said transaction get reversed. The operator sending those transactions to the higher layer is penalized and the validator issuing the fraud proof is rewarded.

The advantage of using optimistic rollups is that users can execute transactions instantaneously on the rollup network. However, they cannot port their assets to the layer 1 network until the challenge period ends.

Layer 3 rollups disperse blockchain functions over an extra layer, increasing transaction rates exponentially – much higher than layer 2s. Looking deeper, layer 2s increase throughput by taking on dApp executions and bundling transactions to be settled on layer 1s. Doing so reduces the loads experienced by layer 1 nodes that traditionally took on multiple functions together, like dApp executions, transaction settlements, and data availability requirements.

The layer 3 approach reduces the burdens of layer 1s even further. It abstracts their functions more than what layer 2s do, thereby driving transaction throughput through the roof. Layer 3 chains handle contract executions, push data availability to DA networks, and transaction bundling to layer 2s, leaving only settlements and validation to layer 1s.

That way, layer 3s distribute the loads effectively and achieve impressive scalability. Moreover, layer 3s are customizable to handle the dApps they are built for specifically, providing the fluidity needed for an efficient and quick execution environment.

App-specific blockchains will provide the impetus for a new generation of Web3 applications, allowing them to exhibit use cases thought impossible on-chain and taking existing ones to improved efficiency. That’s not it. Layer 3s will drive the multi-chain future, establishing secure cross-chain communication across various layer 2 networks. As a result, the growing layer 3 sector will fill the gaps in Web3’s user experience and elevate it on par with what Web2 demonstrates. And that has already begun on Base.

Base, a fairly new layer 2 solution built on the OP stack, is attracting developers in droves thanks to its impressively low transaction fees and rapid transaction finality. All while effectively deriving Ethereum’s layer 1 security. Now, layer 3 ecosystems composed on top of the Base infrastructure can maximize layer 2’s capabilities to unimagined heights.

Thus, RaaS platforms are taking advantage of Base’s innovatory infrastructure to offer easily deployable layer 3 chains with all the integrations projects need to build and launch applications. Building use cases around gaming, finance, DePIN, and social networks has never been this easy, especially when developments with Web3 user experience and functionalities are close to that of Web2. RaaS solutions integrate modularity into launching layer 3 rollups, enabling smart contracts to execute advanced functions alongside improved privacy and AI integrations.

3Base smart contracts come with MultiSig (multi-signature) and MPC (multi-party computation) implementation, meaning altering them without the approval of multiple team members is impossible. That breeds tremendous levels of security, preventing user funds from being extracted by cyberattacks or internal exploits.

Audited contracts, in tandem with 3Base’s use of battle-tested stacks, provide the safest environments for developers to deploy apps and end-users to interact with high-speed Web3 use cases.

Despite blockchain technology revolutionizing several industries, its primary drawbacks and issues remain, preventing the depth with which it can drive decentralization through transformative use cases. The lack of scalability and interoperability has been widely discussed, with many innovators working to overcome these obstacles.

Layer 3 solutions are a direct answer to this need – not just a mere progress for the technology or a manifestation of trends. Simply put, layer 3 solutions are a need of the hour, the answer builders in the Web3 ecosystem looked for all this while. They can now build applications that enjoy high throughput and interoperability to serve user bases effectively and gain impressive adoption.

Base’s lightning-fast rollup capabilities powered by Ethereum’s robust security is the perfect foundation for building a new layer to advance blockchain potential. Nevertheless, why are layer 3 solutions catching on now?

Base’s Scaling Upgrades – The Base blockchain is witnessing constant advancements in scalability. While Base was launched to the public in August 2023, Ethereum’s Merge, which came a year prior, can be viewed as the first advancement to Base’s scaling endeavors as it marked Ethereum’s move toward a scalable future. Beyond that, the continuous upgrades improving efficiency on Base make it conducive to building layer 3 solutions that amplify its scalability.

Raging Ethereum Layer 2 Adoption – Ethereum’s layer 2 ecosystem remains one of the fastest-growing segments in the blockchain landscape. Witnessing massive developer and retail support, Ethereum layer 2s like Arbitrum and Optimism, among others, exhibit tremendous amounts of total value locked (TVL), showing the massive interest in scaling solutions and how they are the way forward.

Layer 3s will achieve significant traction considering the need for scaling solutions with their capabilities to take throughput rates even further. With Base becoming a top Ethereum layer 2, deploying layer 3 solutions on it makes perfect sense.

Advanced dApp Complexity – As Web3 evolves to offer increasingly complex utility to users, layer 3 scaling solutions facilitate the execution environments for robust computations. Layer 2s, despite their upgrade in scalability from layer 1s, cannot efficiently manage the requirements for complex use cases. With layer 3s making their way to provide the highest levels of efficiency seen, developers can deploy utility thought impossible on-chain, taking advantage of the rapid transaction potential and the impressive interoperability.

Base’s Efforts Towards Efficiency – The Base blockchain is gaining tremendous developer support for one reason – its continued effort to provide a bleeding-edge platform for builders to harness. Its tech stack, integrations, and upgrades ensure the greatest levels of interoperability observed so far and allow dApps to execute highly complex functions. All that while maintaining tremendously high transaction rates. Simply put, Base is where today’s decentralized ingenuity is noticeable.

Of course, Base is a fairly new layer 2 with a lofty vision. And it explains why most of the developments in its ecosystem are in the experimental stages. Regardless, the capability of the experimental innovation coming out of it is noticed far and wide. Teams from across the Web3 ecosystem are commencing the launch of or planning on launching the next generation of decentralized utility on Base.

Over 50 teams are already working to implement layer 3 solutions on Base. As layer 3 rollup platforms take full effect, the network will see an influx of developers and users, building and interacting with one-of-a-kind utility, respectively. The need for efficient Web3 infrastructure is obvious. Layer 3 RaaS platforms will address it on Base. Their ability to reduce the headaches of complex infrastructure management will allow the developer community to implement novel dApps effortlessly.
