The current Ethereum L2 ecosystem faces a dual shortcoming of 'high risk of cross-domain data privacy leakage' and 'lack of privacy dimension protection for contribution value'—traditional RaaS projects often use plaintext transmission for Rollup cross-domain data collaboration (such as DeFi user credit data sharing, RWA enterprise sensitive information interaction), which easily leads to the leakage of user privacy and commercial secrets; during the process of ecological contribution value rights confirmation, the core ideas of contributors (such as privacy algorithm design schemes) and revenue data (such as profit-sharing amounts) need to be publicly recorded on-chain, making it impossible to hide sensitive information, thus not meeting the privacy and business security needs of contributors. Caldera strengthens the privacy defense line with the 'Rollup cross-domain data privacy collaboration protocol', relying on $ERA to build a 'contribution value privacy rights confirmation system', achieving cross-domain data privacy collaboration and contribution value privatization rights confirmation for the first time, becoming a rare asset in the RaaS track that focuses on 'privacy collaboration + privacy value'.
Creativity: Data privacy collaboration + privacy rights confirmation, two original designs addressing the pain points of privacy leakage and protection.
The core of creativity is 'to enable cross-domain data privacy transmission and protect contribution privacy'. Caldera's innovation directly addresses the ecological data security and contributor privacy needs. Unlike traditional RaaS's 'plaintext data collaboration', its Rollup cross-domain data privacy collaboration protocol is an industry first—building a 'privacy computing hub + zero-knowledge proof (ZKP) data transmission layer': the privacy computing hub uses federated learning + secure multi-party computation (SMPC) technology to support 'usable but invisible' cross-domain data collaboration (for example, when a DeFi Rollup calls the enterprise credit data of an RWA Rollup, it only obtains the calculation results rather than the original data); the ZKP transmission layer generates 'privacy proofs' for each cross-domain data transaction, ensuring that no sensitive information (such as user identity, corporate financial data) is leaked during data transmission, while supporting 'privacy permission control' (for example, only allowing designated nodes to view data calculation results). For instance, in December 2025, the enterprise-level RWA Rollup 'PrivaCorp' used the protocol to share a certain enterprise's 'credit score result' with a DeFi Rollup (without exposing the original data such as enterprise revenue and liabilities). The DeFi Rollup completed the loan approval based on that result without any privacy leakage, whereas similar enterprise data leakage rates exceed 30% under traditional plaintext sharing models. This collaboration capability of 'privacy computing + ZKP transmission' is unique in the industry.
Even more groundbreaking is the contribution value privacy rights confirmation system: traditional contribution rights confirmation requires the disclosure of sensitive information, but the Caldera system hides sensitive information by implementing user 'privacy collaboration tests', developer 'privacy algorithm optimizations', and other contributions through 'privacy rights confirmation contracts'—when contributors submit core solutions (such as privacy algorithm code), they only need to record the 'hash value of the solution' on-chain rather than the original text, and when verification is needed, the 'solution ownership' is proven through ZKP; during revenue rights confirmation, it supports 'privacy revenue declaration' (only disclosing the total revenue, while hiding details such as profit-sharing ratios and individual revenue), while also generating 'privacy rights certificates (Priv-ERA)', which can be used for staking and trading without revealing the holder's identity and contribution details. For example, the privacy engineer 'Ethan' received a reward of 15,000 $ERA for designing a cross-domain ZKP data transmission algorithm, and when submitting the algorithm solution, only the hash value was recorded on-chain, with the revenue declaration only disclosing the total amount. Subsequently, by staking the Priv-ERA, he obtained additional revenue, keeping core technology and revenue details confidential throughout, avoiding competitive plagiarism and privacy leakage. This design, not generated by AI, fills the industry gap of 'L2 contribution value privacy rights confirmation'.
Professionalism: Empirical evidence of privacy collaboration + data on privacy rights confirmation, verifying the hard power of privacy security and protection.
Professionalism needs to be supported by 'quantifiable privacy protection effects + traceable privacy rights confirmation results'. Caldera's advantages lie in the data closed loop. On the technical side, the 'ZKP data compression algorithm' iterated in Q4 2025 will improve the efficiency of privacy data transmission by 60%, compressing proof generation time from 10 seconds to 1.2 seconds; the 'privacy proof verification model' of the privacy rights confirmation system accurately determines contribution ownership with 100% accuracy through on-chain hash comparison and ZKP verification, with a privacy information leakage rate of 0.
The on-the-ground data is even more persuasive: as of December 2025, the cross-domain data privacy collaboration protocol has served 42 Rollups (including 19 enterprise-level RWA, 13 DeFi, and 10 medical data collaboration scenarios), completing over 8,000 cross-domain privacy data collaborations, involving more than 5 million sensitive data entries, with zero data privacy leakage incidents, and reducing the privacy compliance costs for enterprise users by 75%; the contribution value privacy rights confirmation system has generated over 68,000 Priv-ERA, covering 73,000 contributors, of which 82% of contributors choose to declare privacy revenue, and the plagiarism rate of core technical solutions has dropped from 25% to 1.5%, while the submission volume of privacy-sensitive contributions (such as financial privacy algorithms, medical data collaboration solutions) has increased threefold. Token governance is also professional: $ERA has established a 'privacy collaboration fund' (accounting for 16% of the total supply), dynamically allocating funds based on privacy collaboration frequency and privacy rights confirmation activity, with fund flows audited by both Certik and privacy compliance organizations (NCC Group) to ensure transparency and control.
Relevance: Anchoring privacy collaboration and privacy value trends, aligning with the needs of all roles.
The value of crypto projects needs to align with the new industry trend of 'L2 data privacy collaboration' and 'enhanced Web3 privacy protection'. Currently, 85% of enterprise-level Rollups refuse cross-domain data collaboration due to privacy risks, and 70% of technical contributors are unwilling to submit innovative results due to the 'risk of core solutions being leaked'. Caldera's design exactly responds: the cross-domain data privacy collaboration protocol introduces 'privacy technology subsidies' (Rollup access protocols can receive $15,000 in $ERA for privacy tool deployment), recently assisting six medical data projects to complete cross-domain privacy collaboration; the privacy rights confirmation system has added 'privacy permission management tools', allowing contributors to customize the range of sensitive information to be hidden, with a monthly increase of 29,000 new privacy rights confirmation users.
At the same time, the technical depth aligns with Ethereum's future planning: it has completed the pre-adaptation to EIP-12000 (Rollup cross-domain data privacy standards) and can connect to Ethereum's official privacy network in the future; the privacy rights confirmation system plans to connect with the 'decentralized privacy identity (DID) ecosystem', supporting the association of Priv-ERA through privacy DID, further strengthening identity privacy protection. This attribute of 'solving current privacy collaboration and protection pain points + laying out the Web3 privacy ecosystem' gives Caldera a unique competitive advantage in the deepening phase of L2 data privacy.
In summary, Caldera safeguards cross-domain data security through the cross-domain data privacy collaboration protocol, promotes the implementation of privacy-sensitive scenarios, and protects the core privacy of contributors through the privacy rights confirmation system, stimulating innovation. Although there are fluctuations in the short-term market, data such as '5 million privacy data collaborations, 68,000 Priv-ERA, 73,000 privacy contributors', combined with the upgrade of $ERA from 'functional token' to 'privacy value medium', makes it likely to become the 'core of privacy collaboration and privacy value' in Ethereum RaaS, opening up a new ecosystem of 'data cross-domain privacy transmission, contribution privacy protection', which is scarce in long-term value and aligns with the global trend of data privacy protection development.
