 With Aligned's stack, you can generate the proof and then use Ethereum as a settlement layer. To do so, Aligned offers a variety of products to reduce your costs and increase throughput. Once you decide to use ZK for your product and Ethereum, Aligned fits perfectly.
 
 - **Proof Verification Layer:** A decentralized network of verifiers that checks the proofs, signs messages stating the correctness of the proof and when a threshold is met, publishes the signature to Ethereum. Once Ethereum checks the signature, the state of the proofs is changed to verified, and you can use the result as always. It has very high throughput, reduces costs significantly (depending on the number of proofs that are sent) and has low latency.
-- **Proof Aggregation Service:** Performs recursive proof aggregation of several ZK proofs. The final proof is sent to Ethereum, and if verified, it implied the validity of your proof. It has higher latency and lower throughput than the fast mode, but achieves the full security of Ethereum.

 - **Meta Proving Services**: Offers an easy interface for accessing centralized and decentralized proving from external providers.
 - **Rollup-as-a-service (RaaS) platform:** Simplifies ZK-rollup deployment, allowing clients to launch L2 chains with just one click, without needing deep blockchain expertise.
 - **Interoperability protocol:** An intent-based bridge that will be integrated with our RaaS stack. It will leverage based sequencing and enable developers to create native trust-minimized solutions for users and financial institutions to efficiently move liquidity across chains.
