Smart contracts can be built using mainstream software stacks. You can make a leap from Solidity to the vast array of Linux-supported software components. You can achieve a million-fold increase in computational scalability, large file data availability, and low transaction costs. All this while maintaining the strong security guarantees offered by Ethereum. You can keep your DApps private, from games that hide players' data to Enterprise applications that use sensitive data. Descartes performs large computational tasks off-chain on a Linux virtual computer fully specified by smart contracts. The computations are fully verifiable, and can be enforceable on-chain by Descartes node runners. This preserves the strong security guarantees of underlying blockchain. With multimillion-fold computational gains and strong security guarantees, you can overcome the Ethereum scalability limitations.

Many web applications store sensitive data, including financial information and user information. This makes them very attractive to malicious attackers. As web applications become more complex, so will the number of exploitable vulnerabilities. Hacken's web penetration test services are crucial for our clients. Security should be a top priority for all businesses. We offer support and knowledge to help businesses secure themselves.

Zero-knowledge cryptography is used for anonymous KYC and soulbound credentials. Blockchain is the future of trust, according to us. Notebook allows you to protect your identity and data so that you can authenticate in a trustless world. Notebook uses Zero-Knowledge Proofs and fragmented identity to keep users anonymous. A Notebook is stored on-chain within a smart contract. This means that no one or corporation has access to your identity or data except you. A Notebook is the best way for summary statistics to be stored, such as credit score and bad-actor behaviour. Storing such metrics creates a fairer world where everyone is held accountable for their actions and believes in the greater good. An individual cannot create multiple Notebooks by using the PII data required to onboard. However, this does not compromise their privacy. The Notebook's identification system can be disassociated from the user's wallet addresses. This allows the same identity to be used across-chain.
