Obscu.ro is a startup that operates in the blockchain technology sector, specifically focusing on Ethereum, a decentralized, open-source blockchain with smart contract functionality. The company has developed a product called Ten, a Layer 2 rollup solution that enhances the scalability and security of Ethereum.

In simple terms, a Layer 2 rollup is a secondary layer built on top of a blockchain (in this case, Ethereum) to increase its transaction capacity and speed. Obscu.ro's Ten does this while also adding encryption, which provides an additional layer of security and privacy.

The company's primary clients are developers who use Ethereum to build decentralized applications (dApps). Ten allows these developers to integrate both public and private elements into their smart contracts without altering the user experience. This means that every Ethereum application can become an encrypted dApp without any changes, making the transition from Ethereum to Ten seamless for end users.

Obscu.ro's business model is based on providing a solution that enhances the Ethereum ecosystem. The company makes money by offering a platform that allows for faster, cheaper transactions on Ethereum, while also eliminating negative Maximal Extractable Value (MEV) issues. MEV refers to the profit miners can make by strategically ordering, including, or excluding transactions in a block. With Ten, only positive MEV exists, which improves transaction security and fairness.

In addition, Ten uses a unique Proof of Block Inclusion (POBI) protocol that ensures rapid asset withdrawals to Ethereum, outpacing other Layer 2 solutions. As a user-run, decentralized network, Ten guarantees resilience and censorship-resistance.
