Unlocking Privacy Features with COTI Sandbox and the Data Privacy Framework.

Over the past weeks, we’ve been diligently working to enhance the COTI SDK. Today we’re excited to reveal our progress on several key features that aim to improve the developer experience. These include:

1. Data Privacy Framework (DPF). The DPF enables the development of private smart contracts, a powerful feature of COTI’s privacy L2.

2. COTI Sandbox environment. The Sandbox allows for testing of privacy implementations in a risk-free environment, opening the doors to innovation in Web3.

Let’s dive into the details of these exciting developments!

Innovating Smart Contract Access with the Data Privacy Framework (DPF)

Imagine having the ability to control who interacts with your smart contracts and under what conditions — all with precision and ease. Introducing the Data Privacy Framework (DPF). The DPF empowers developers with the tools to manage access to sensitive data within smart contracts, a core component of the COTI V2 privacy solution.

The Data Privacy Framework (DPF) takes privacy and security a step further by enabling developers to implement fine-grained access control directly within smart contracts. This powerful feature complements the privacy-preserving capabilities of COTI V2, allowing for more sophisticated and secure dApp development.

The Data Privacy Framework (DPF) offers several key features:

• Conditional Access: Developers can set specific conditions on who can access, call, or view information handled by their smart contracts.
• Flexible Rule Definition: Rules can be based on various parameters such as wallet addresses, timestamps, or custom conditions.
• Easy Integration: Developers can import DPF into their smart contracts and write operations to manage data access based on defined rules.

DPF can handle sophisticated access control mechanisms, tailored to specific use cases and regulatory requirements. For example, in a KYC (Know Your Customer) scenario, DPF allows for the creation of smart contracts that only grant access to user identity data when a service provider meets certain predefined conditions. Additionally, contract owners can define different users to read/write data based on these conditions, while maintaining full privileges over their data.

Offering this level of granular control ensures that sensitive information is only accessible to authorized parties under the right circumstances, maintaining user privacy while enabling necessary compliance checks.

The COTI V2 Developer Sandbox

As we continue to expand our developer tools, we’re excited to share a glimpse into our upcoming COTI V2 Developer Sandbox. This will form an innovative web-based environment providing a comprehensive playground in which to test and experiment with COTI V2’s privacy features.

Key Features (coming soon):

• Permissions Management: Define and experiment with smart contract access rules.
• Data Encryption: Add and encrypt data directly on the blockchain.
• Activity Tracking: Monitor every move on-chain with detailed activity logs and speed up the debugging process.

The Sandbox will allow developers to quickly become familiar with both the COTI network as well as the DPF by setting up conditional access rules for smart contracts, visualizing encrypted data on-chain, and testing multi-party computations on encrypted data.

The Sandbox provides developers with the practical tools they need to get started with COTI. For instance, the COTI Sandbox is a great resource for dApp developers aiming to build applications with enhanced privacy features, where data can be securely encrypted on-chain.

The Sandbox also allows developers to experiment with smart contract access rules which have many applications, for example, in enabling confidential DeFi, where it can be used for collateral management, interest rate calculations, and liquidation processes. Developers can use the Sandbox to test privacy as an application layer anywhere that intricate logic and contractual agreements are needed on-chain.

COTI’s V2 privacy technology, based on Garbled Circuits, enables secure multi-party computation without the high costs associated with other privacy solutions. This makes the Sandbox an ideal testing ground for ideas that were previously out of reach for many developers, such as collaborative data analysis, privacy-preserving machine learning models, fully private DEXs, secure voting systems, auditing systems and IoT applications.

With the COTI Sandbox, users can quickly try out privacy features and experiment with different scenarios, accelerating development time and fostering faster innovation.

COTI is opening a new chapter for decentralized applications where security and privacy is more than just an ideal — it’s the foundation on which everything is built.

Keep an eye out for further updates on our growing technology stack, along with integration guides to help you navigate our new tools.

Stay tuned, and get ready to transform what’s possible with COTI!
