Sharding is like shelves in the library, where books starting with A-D are known to be on the first shelf, and so you don’t need to scan the whole library.
If you haven’t designed the shelves from the day one, your library will never be efficient.
This is exactly how NEAR is different from any other chain
Nice to see people loving NEAR's dynamic resharding. But I want to flag what it actually is: not a 2026 feature, but the payoff of a bet NEAR placed on day one, to shard the chain.
Sharding splits the chain into parallel lanes so no single lane jams. But there's a catch. To check a lane, a validator (a machine that verifies the chain) normally has to store everything in it, so the number of lanes is capped by what one machine can hold, and adding a lane meant a slow, coordinated, network-wide upgrade. Real sharding needs validators that can verify a lane without storing it. That was the missing piece for years.
NEAR shipped it in 2024, and that's the actual breakthrough: stateless validation. A validator now checks a lane from a small proof package, a slice of data plus a cryptographic receipt that it's correct, and never stores the lane. The correctness of a split is proven inside that package. So lanes stop being capped by one machine, and a lane can even split while the traffic is still moving. Dynamic resharding is that capability put on autopilot.
This is why almost nobody else has it. Solana, Sui, Aptos, Monad never sharded, so they never needed it: one big machine does everything. That has a cost, though. A single machine has a ceiling, so the harder you push it the more brutal the hardware gets and the fewer people can run a node, and a big enough spike can stall the whole chain. Ethereum does need sharding's relief, but its original data structures make those proof packages huge, so getting there means migrating its entire live state to a new design, a multi-year job they keep redesigning, and once Ethereum pushed scaling onto L2s the urgency drained out. NEAR is the rare chain where sharding was the whole thesis, so solving this was do-or-die.
And the bet keeps compounding. NEAR adds capacity by adding lanes while staying one road, one shared state, no bridges. Ethereum scaled by splitting into 20 separate roads (its L2s), and this March it had to launch a whole project just to glue them back so they can talk instantly again. NEAR never split the road.
So enjoy dynamic resharding. Whether the agent traffic it's built for actually shows up is a separate question. The engineering under it is a years-old bet finally cashing out.
