The largest upgrade of Ethereum since its transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) 18 months ago, called “Dencun,” is expected to launch on Wednesday evening (13th) Taiwan time. The overseas blockchain media “CoinDesk” has summarized five things to know about this upgrade.
The Gasless Era of Ethereum
Dencun will make transactions on Ethereum Layer 2 super cheap – almost costless, to the point where almost all activities on Ethereum will shift to these networks. There may even be projects or protocols that incentivize usage by covering the gas fees users typically have to pay (which is cheaper than paying marketing fees!).
A Major Milestone
Dencun is the largest upgrade for Ethereum since “The Merge” in September 2022, and it is also one of the steps towards achieving Ethereum’s ultimate goal – supporting hundreds of different Rollups and Layer 2 scaling solutions and eventually processing millions of transactions per second.
Long-Awaited
Dencun will introduce the “Proto-Danksharding” process, a concept that has been theorized for a long time (first mentioned by Ethereum founder Vitalik Buterin in 2019), which will change how Ethereum stores data. Unlike the costly and computationally heavy practice of storing all data directly on the Ethereum mainnet’s immutable execution layer, Dencun will introduce a new, temporary data storage method called “blobs,” which is more cost-effective. Although “blobs” may sound like an informal term, they are actually a common concept in computer science and have similar data management concepts in programming languages like JavaScript and Python.
The Origin of Proto-Danksharding
Proto-Danksharding is named after two Ethereum researchers – Dankrad Feist and Proto Lambda – who proposed this change. The name is fitting because Proto Danksharding is a necessary condition for the full-fledged implementation of Danksharding, which will further simplify the concept of data storage but will take several years to achieve. Additionally, although the term includes the word “sharding,” both Danksharding and Proto-Danksharding are not traditional methods of dividing databases into smaller parts, which is the original plan for Ethereum to achieve scalability. In a sense, Dencun’s introduction of Proto-Danksharding deviates significantly from Ethereum’s initial roadmap, but it was chosen because it is easier to implement.
The Largest Trusted Setup Ceremony in History
The first step in establishing Proto-Danksharding took place during the largest Trusted Setup ceremony in the world held in 2022. It involved multiple researchers (Aniket Kate, Gregory M. Zaverucha, and Ian Goldberg) whose names are associated with creating a critical component that makes it possible to store blobs on Ethereum. Tens of thousands of people participated in the “KZG ceremony,” which was a way for the Ethereum community to collectively generate the secret random string data required for the operation of proto-danksharding.
