Expanding Capabilities to Cater to the Needs of Widespread Adoption: Enhancing DApps Scalability

Fifteen transactions per second: that's not too shabby, right? This figure represents the higher end of Ethereum's typical handling capacity at this time. Depending on transaction types and sizes, this number can slightly fluctuate – post-Dencun upgrade, the theoretical maximum can reach 173 – but in general, Ethereum manages to process around 15 TPS.

This limitation is attributable to various factors, primarily focusing on maintaining the security and decentralization of the Layer 1 (L1) network. Nevertheless, this figure isn't static. Layer 2 rollup solutions such as Optimism, Arbitrum, and zkSync are rapidly enhancing Ethereum's scalability. By managing transactions off-chain and submitting them in more optimized packets, they can fit larger numbers of transactions into each block, thereby increasing overall TPS.

Ultimately, the goal is to scale TPS into the thousands through further optimizations in data handling, compression, and storage. This endeavor represents one of the most significant challenges facing the community today and is critical for widespread adoption.

The need for faster transactions is paramount. Everything from trading platforms to payment solutions and online multiplayer games relies heavily on swift transaction completions. Users now expect this kind of speed for any online service, and decentralized platforms must meet that expectation to encourage mass adoption within the web3 ecosystem.

What Is Mass Adoption?

We're all eagerly anticipating that game-changing application that will shift the paradigm and bring in the next hundred million users. It could be an effortless payment solution akin to the convenience of a credit card, a digital ticket for events that you can easily purchase and scan at the entrance, or even a reward system that grants tokens to countless users for contributing to a popular social platform.

In fact, many of these innovative concepts are either in existence or already available for use. Yet, despite this progress, we're not significantly closer to achieving mass adoption than we were five years ago. So what’s holding us back? Here are a few key challenges:

• Blockchain technology can be quite tricky to use. This poses a challenge even for those who are tech-savvy, let alone for the average user or that lovely grandma you’d like to get on board. The user experience (UX) is often not straightforward, and the necessity to navigate through multiple chains and rollups for enhanced speeds contributes to confusion and fragmentation.
• The blockchain landscape can be quite intimidating. Given the prevalence of scams and hacks, trusting various applications and signing transactions can be frightening, especially knowing you could potentially lose all your assets with a single click.
• The underlying transaction speed limitations within a secure and decentralized network present a significant hurdle.

To truly achieve widespread adoption of blockchain and cryptocurrency, we need to confront each of these challenges head-on. However, focusing on one central concern can help us make progress on them all: scalability.

Why Scalability Matters

Scalability encompasses more than just speed. It relates to reaching a broader audience, accommodating various transaction types, and ensuring a high-performing, secure environment. A scalable blockchain can tackle numerous issues, reducing inefficiencies in our global financial networks and empowering individuals to take charge of their own finances and destinies.

However, in order to unlock this potential, decentralized applications (dApps) need to be quick, secure, and user-friendly. dApps have to facilitate a diverse range of users on their journeys through different chains while efficiently managing their multi-chain accounts. It's crucial for dApps to eliminate much of the inherent complexity in the blockchain space so that users can grasp what they're doing and feel secure in their financial transactions.

Simplifying the Blockchain User Experience Through Account Abstraction

One of the most challenging aspects for newcomers to blockchain is understanding the concept of accounts. Public account numbers can be long and cryptic (which is intentional), and it involves the use of private keys for transaction signing. Users must also protect these keys, along with the seed phrase for account recovery, to safeguard their assets. To initiate transactions, an account must hold a minimum amount of ETH (or another native token based on the specific chain) to cover gas fees.

These fundamental account principles can be quite foreign to many, and the anxiety of keeping everything straight, safely stored, and acquiring ETH for transaction fees can be overwhelming. Such hurdles often deter new users from pursuing their blockchain journey.

Account abstraction (AA) mitigates many of these obstacles. By employing AA, smart contracts can take the place of traditional externally owned accounts. As smart contracts offer much greater flexibility and can be customized for varying applications, they pave the way for user-friendly enhancements in account management. For instance, AA permits other tokens (beyond just the native token like BTC or ETH) to be employed for gas fee payments. Furthermore, it promotes features like sponsored transactions, where the application itself covers the gas fees on behalf of the user. Additionally, AA can facilitate account recovery options, allowing for key backups or shared management by multiple individuals.

These features enhance security while simplifying the onboarding process and encouraging a larger user base. While account abstraction streamlines user acquisition by removing account-related hurdles, chain abstraction fosters scalability across the entire ecosystem.

Chain Abstraction: A Game-Changer for Widespread Blockchain Adoption

Ethereum’s rollup-centric roadmap Since 2020, chain abstraction has provided a scalable framework. By 2024, we've witnessed significant advancements with the ongoing introduction of rollups that are successfully attracting users. Transactions facilitated through rollups tend to be much more affordable and efficient, leading to the emergence of applications designed to deliver anticipated as well as innovative DeFi functionalities.

However, a notable challenge persists in the form of fragmentation. There might be a more attractive incentive scheme on a different chain, or a particular application may only be accessible through a specific rollup. As a user, keeping track of which chain you used for a transaction, then potentially needing to navigate a bridge to transfer tokens for another app on a different chain, can quickly become convoluted.

Chain abstraction aims to dispel this confusion and fragmentation. Developing user interfaces that offer cohesive views for actions across numerous chains is underway. This will allow users to effortlessly view transactions, engage with applications, and transfer tokens without being bogged down by the complexities of the underlying chains. A user shouldn't need to know the chain in which their USDC was received; they should only need to see that their USDC has arrived safely in their account.

The complexities surrounding chain abstraction will be resolved by software capable of merging cross-chain transactions into one fluid interface. We are already witnessing the emergence of this in various portfolio management tools and wallet applications, while multi-chain block explorers will be essential in providing an overview of transactions as they navigate through various chains.

The Future Of DApp Mass Adoption

With a solid scalability strategy in place, the road to mass adoption of blockchain and cryptocurrencies becomes significantly smoother. Transactions become quicker and less expensive, complexities are simplified, and dApps can potentially evolve to resemble the applications we regularly interact with on our devices.

Most individuals typically do not ponder which data center facilitates their app data or what steps they should take if they forget their account password. Similarly, users rarely focus on speed unless an app is particularly slow, in which case they might opt not to use it at all. The same logic should apply to interactions within the blockchain space. Once speed and scalability are taken for granted, addressing any remaining obstacles to blockchain involvement will become much simpler.
