Ethereum’s Dencun Upgrade is Indeed a Massive Milestone, But it Also Poses Concerns

Ethereum’s Dencun upgrade is finally live, and this is a good reason for investors to rejoice. This development has been widely anticipated, as it addresses some of the most significant issues that Ethereum faces, setting the foundation for endless possibilities. Proto-dank sharding, the primary change that the Dencun update brings, is the first step towards sharding, a method designed to enhance the capacity of the chain transactions by providing new lanes to the proverbial blockchain highway. This is a feature that seeks to lower fees for layer 2 rollup networks, enabling users to transact for cheap while also ensuring they won’t completely leave the ecosystem.

Many developers are enthusiastic about the Dencun upgrade and its massive potential to improve Ethereum’s affordability. However, some worry that it could hurt the ecosystem. Are these concerns legitimate and a reason to be cautious about what could happen next? Keep reading to find out as we discuss the Dencun upgrade in more detail.

What Proto-danksharding Truly Means for the Ethereum Ecosystem

Compared to other networks, Ethereum’s fees are significantly higher, and this has been a reason why its network has struggled for a while. At the time of writing, it costs over $16 to swap tokens on the Ethereum mainnet, which is indeed a problem if you think about it. However, now that the Dencun upgrade is completed, gas fees on L2 rollups are expected to be reduced considerably. Proto-danksharding is also meant to optimize the Ethereum network to accommodate rollups effectively – which have exceeded Ethereum in the total transaction volume. Simply put, this feature introduces blobs – a new data structure for the layer-2 rollups, which can put data back into the Ethereum chain’s base.

Although proto-danksharding seems complex, it is a much-needed advancement in the Ethereum ecosystem and blockchain technology, contributing to scalability. However, it is worth noting that proto-danksharding only lays the groundwork, as the final goal is to fully implement danksharding, enabling the attachment of more than 64 blobs per block. Danksharding involves considerable upgrades to consensus client operations, including separation and data availability sampling, as well as proposer-builder separation. These are already part of the roadmap that Buterin envisioned for Ethereum. While there’s still a long journey ahead until full danksharding comes to fruition, the implementation of proto-danksharding is a major milestone in Ethereum’s ambitious plan for the future.

Amidst the Enthusiasm, There are Fears of Fragmentation and Rollup Security

The shift towards cheaper layer-2s makes sense in terms of Ethereum’s accessibility, but some developers are concerned that relying on third-party networks could have a massive consequence, fragmenting the Ethereum ecosystem and affecting its use case as the leading blockchain “settlement layer.” They believe that pushing users from Ethereum to other L2s implies giving up Ethereum’s position as a general-purpose platform and letting it turn into a general-purpose computer, shifting dominance to other protocols. Moreover, the bulk of transactions on L2s could cause the economic incentives that uphold the L1 to be diluted due to the evaporation of validators’ fees. In addition, relying on L2s could weaken Ethereum’s interoperability and cohesion due to the activity’s fragmentation. However, according to one of Ethereum’s core developers, this isn’t something to worry about. Developer fragmentation isn’t a bug but rather a feature to benefit from, as it allows different individuals to experiment with various kinds of rollups and deploy them – a valuable opportunity they didn’t have before.

Another concern is related to the security of rollups. Essentially, rollups are designed to borrow the security of Ethereum – they bundle up users’ transactions and then transfer them to the base chain while trying to ensure the same protection. L2s have different designs, and users who seek to access all use cases of Ethereum must trust different blockchain rulesets for that. However, it’s worth noting that layer-2 rulesets aren’t all the same, and today’s massive rollups have non-existent proof systems or centralized sequencers (known as training wheels) that only operate based on user trust.

Despite the worries that rollups don’t provide the same security as Ethereum L1, core developers of Ethereum state that this shift towards cheaper networks is inevitable for Ethereum, and it’s essential to adapt to reality. To further demystify the debate regarding layer 2 scaling solutions, we can make an analogy with airlines. Saying that rollups aren’t secure enough is like saying that economy seats aren’t a good idea because they don’t offer maximum comfort, even if they are cheap. In reality, having different tradeoffs helps improve the underlying network’s utility. Now, this isn’t to say that blockchain’s security is the same as comfort on an airline – the former is indeed a pressing need. However, it’s worth noting that all solutions provide fundamental security that enables them to operate at trivial levels when it comes to security failure. It simply doesn’t make sense to criticize a solution because of this – after all, we can’t overlook how powerful it is, offering developers different options to choose from.

Closing Thoughts

Despite the concerns regarding Dencun, this upgrade remains a significant milestone for Ethereum and a leap forward in its journey towards improving the network’s efficiency. Dencun has massive implications for the Ethereum ecosystem and the overall crypto landscape, and it is just the first step of a bolder path. Can you imagine a blockchain that effectively processes over 100,000 transactions per second? It sounds incredible, doesn’t it? Well, that’s where Ethereum is headed, so this scenario could become a reality at some point.

Without a doubt, the Dencun upgrade marks the beginning of a transformative phase for the Ethereum ecosystem, so investors, developers and crypto enthusiasts should keep an eye on the news to see what happens next. By actively contributing to the Ethereum ecosystem, they can ensure that Ethereum reaches its goals, ultimately evolving into what it is meant to be: a more inclusive and forward-thinking platform that is accessible to everyone interested in a brand-new technology with such excellent features and use cases.
