0/ similar to the sequencer, a centralized prover in #zk-rollup systems can introduce centralization & single-point-of-failure risks ⚠️

1/ #zk-rollups demand an off-chain #prover to generate a succinct proof for a batch of transactions. However, proof generation for complex smart contract transactions can be expensive, leading to several limitations in functionality
2/ firstly, let's dive into the typical rollup tx flow ⬇️
⚙️ Users send transactions to a centralized #sequencer on #L2
⚙️ The sequencer executes transactions, packs (& orders) them into a #rollup block
⚙️ Centralized #prover generates a succinct proof of the sequencer's batch

🔒 The blockchain trilemma has always been a difficult problem in the industry. Rooch's solution? A Rollup Layer2 secured by Layer1 which allows for asset interoperability with Layer1 #Ethereum.
👨💻 Rooch's Rollup solution is modular, with multiple contracts on the chain playing different roles, representing different modules. Developers can meet different application scenario requirements through module assembly. #ModularBlockchains
🚀 Rooch's MoveOS includes MoveVM and StateDB, the system's execution and state storage engines, while RPC provides query and transaction submission services. #movelanguage
Drawing Innovation: @illumina Super-Resolution Optics
Recently, $ILMN unveiled the NextSeq 2000, a mid-throughput sequencer w/ a ~2X reduction in operating costs ($/GB).
We think the upgrades inside the NextSeq 2000 may soon enable a $100 clinical-depth human #genome.
But how?

We think the upgrades inside the NextSeq 2000 may soon enable a $100 clinical-depth human #genome.
But how?
The cost savings come from (1) a new upfront #chemistry and (2) super-resolution optics. We think @illumina will use real-world customer data on the NextSeq 2000 to optimize 1 and 2, then possibly upgrade the #NovaSeq line.

I'm going to briefly (!) illustrate how #sequencing (*by synthesis*) works, walk through a farming analogy, then dive into some technical details. (Sources at the end)
