Peeling away those marketing layers, Linea is actually more like a dedicated technical craftsman.

It didn't intend to set up a rival to Ethereum; instead, it chose a more pragmatic route - to equip Ethereum's mainnet with a "turbocharger." How you originally wrote contracts, connected wallets, and used tools remains the same, but now the heavy lifting of calculations is moved to layer two for centralized processing. After processing, what happens? A verifiable mathematical proof is submitted to the mainnet - the mainnet only acts as the referee, while layer two does the heavy lifting.

What does it feel like when it falls into the hands of users? The operating habits remain unchanged, the speed is faster, and the fees are cheaper. Institutions focus on another set of logic: a clear technical route, traceable accounts, and quantifiable risks. This sense of "reliability" is quite appealing in the current context where compliance requirements are becoming increasingly stringent.

Technically, it is a Type-2 zkEVM, which translates to: it executes according to Ethereum's coding rules and then uses "recursive proofs" to compress a batch of transactions into a single PLONK proof for submission. The specific process is as follows - the sequencer first queues the transactions for quick confirmation, then the prover calculates this batch of transactions into a "validity certificate," and finally, the Ethereum mainnet verifies its authenticity.

Behind them are proof frameworks like Vortex and Arcane providing support. What is their function? On one hand, they increase transaction throughput; on the other hand, they reduce the cost per transaction. More importantly, this architecture has considered the balance between censorship resistance and decentralization from the very beginning of its design — for developers, the migration cost is nearly zero; for users, the experience is smooth and cost-effective.

No frills, just focus on "doing the Ethereum job more efficiently" and sticking to that goal. Linea's approach is quite to my taste.
