Will **Ethereum (ETH)** officially complete the transition to a **sharded network architecture** before the end of 2028?

Ethereum's Final Scalability Frontier: The Sharding Deadline of 2028

After the successful 'Merge' (Proof-of-Stake transition), the next and arguably most complex phase of the Ethereum roadmap is achieving true scalability through **sharding** (specifically **Danksharding**). This is designed to break up the blockchain's data load, enabling a theoretical increase in transactions per second from dozens to **over 100,000**.

The Complexity of Decentralized Engineering

While the initial steps, like **Proto-Danksharding** (implementing 'blobs' for Layer 2 rollups), are already underway to reduce gas fees, the full realization of Danksharding is a massive, decentralized engineering project. It involves coordinating thousands of developers and node operators globally through multiple protocol upgrades. The timeline is not dictated by a single CEO but by community consensus and rigorous testing.

Historical cryptocurrency protocol upgrades have frequently faced delays due to the need for extreme security and meticulous code auditing. While the Ethereum Foundation is driven and well-funded, aiming for full sharding completion by the end of 2028 is a very ambitious goal. It represents the optimistic end of the development spectrum, highly dependent on avoiding unforeseen technical pitfalls in cryptographic design and implementation.
