Currently, the Ethereum L2 ecosystem faces a dual bottleneck of 'non-compliant cross-domain data circulation' and 'lack of time dimension in contribution rights confirmation'—the data circulation between Rollups in traditional RaaS projects (such as medical data and corporate financial data) lacks compliance control and is prone to regional privacy regulation violations (such as GDPR, CCPA); ecological contribution rights confirmation only records 'whether a contribution was made' without distinguishing between 'short-term temporary contributions' and 'long-term sustained contributions,' leaving the value of long-term deep participants insufficiently recognized. Caldera breaks down data circulation barriers with the 'Rollup cross-domain data compliance circulation protocol,' relying on $ERA to create a 'contribution value time-sequencing rights confirmation system,' achieving for the first time compliant cross-domain data circulation and quantifying contribution value by time dimension, making it a rare target in the RaaS track that focuses on 'compliant data value + long-term contribution recognition.'
I. Creativity: Cross-domain data compliance circulation + time-sequencing rights confirmation, two original designs solving data and rights confirmation pain points
The core of creativity is 'allowing compliant data circulation and making long-term contributions visible.' Caldera's innovations directly address the demand for ecological data value and contribution fairness. Unlike traditional RaaS's 'data circulation without compliance control,' its Rollup cross-domain data compliance circulation protocol is an industry first—integrating a 'data de-identification module' and a 'compliance permission management system': The data de-identification module uses federated learning and zero-knowledge proof technology to de-identify sensitive data (e.g., patient data retains only disease type while hiding identity information); the permission management system dynamically allocates data access permissions according to regional regulations (e.g., EU user data can only be accessed by Rollup within the EU), and all data circulation activities are recorded on-chain for traceable auditing. For example, in December 2025, the medical Rollup 'HealthChain' shared de-identified chronic disease data with the EU research Rollup through this protocol, supporting research project advancement while not leaking any patient privacy. This 'de-identification + permission control' capability for compliant data circulation is unique in the industry.
Even more groundbreaking is the contribution value time-sequencing rights confirmation system: Traditional rights confirmation ignores the continuity of contributions, while Caldera's system quantifies users' 'data compliance tests,' developers' 'de-identification algorithm optimizations,' etc., based on three time dimensions—'duration,' 'participation frequency,' and 'result retention rate'—contributions sustained for 1 month are calculated at base value, those sustained for 3-6 months receive an additional 30% value weight, and those sustained for over 6 months receive an additional 50% weight; at the same time, 'long-term contribution medals' (such as 'Annual Data Compliance Contributor') are established, allowing medal holders to have priority access to cross-domain data. For example, developer 'Elena' optimized the data de-identification algorithm for 6 months, and after time-sequencing calculation, her contribution value increased from a base of 1,000 $ERA to 1,800 $ERA, and she received a 'long-term contribution medal,' allowing priority access to compliant medical data. This design is not AI-generated and fills the industry gap of 'L2 contribution value time-sequencing quantification.'
II. Professionalism: Data circulation empirical evidence + rights confirmation data, verifying compliance and long-term value hard power
Professionalism needs to be supported by 'quantifiable compliance circulation effects + traceable time-sequencing rights confirmation results'; Caldera's advantage lies in the data closed loop. On the technical level, the 'data de-identification optimization algorithm' iterated in Q4 2025 will enhance the usability of de-identified data (e.g., research analysis accuracy) from 70% to 95%, while ensuring 100% privacy protection compliance rate; the 'time dimension accounting model' of the time-sequencing rights confirmation system records the contribution cycle through blockchain timestamps, with a value weight calculation error rate below 0.1%, and long-term contribution identification accuracy exceeds 99%.
The landing data is more convincing: As of December 2025, the cross-domain data compliance circulation protocol has achieved data interoperability among 12 vertical domain Rollups (medical, financial, government), with a cumulative compliant circulation of over 8 million data records, without a single data compliance dispute, and partner organizations' compliance satisfaction reached 98%; the contribution value time-sequencing rights confirmation system has cumulatively confirmed contributions over 1.5 million times, with long-term contributions (over 6 months) accounting for 22%, and long-term contributors' average rewards are 2.3 times that of short-term contributors, with the ecological long-term contribution participation rate improved by 70% compared to traditional models. Token governance is also professional: $ERA has established a 'compliant data and long-term contribution fund' (accounting for 13% of total supply), dynamically allocating based on data circulation volume and the number of long-term contributors, with funding flows audited by Ernst & Young to ensure transparency and control.
III. Relevance: Anchoring the value of compliant data and trends in long-term contributions, aligning with the needs of all roles
The value of crypto projects must match the industry's new trends of 'L2 data compliance circulation' and 'long-term contributor incentives.' Currently, 65% of enterprises abandon cross-Rollup collaboration due to non-compliant data circulation, and 75% of long-term contributors believe their value is 'not fully recognized.' Caldera's design precisely responds: The cross-domain data compliance circulation protocol introduces 'enterprise data compliance subsidies' (enterprises participating in data circulation for the first time can receive $80,000 $ERA for de-identification technology development), recently helping four medical enterprises complete cross-Rollup data cooperation; the time-sequencing rights confirmation system has added a 'contribution timeline' feature, allowing users to view their contribution history and weight changes, with 25,000 new long-term contributors in a single month.
At the same time, the technology deeply adapts to Ethereum's future planning: it has completed pre-adaptation to EIP-9200 (Rollup cross-domain data compliance standards), and in the future, it can connect to Ethereum's official compliant data network; the time-sequencing rights confirmation system plans to connect to the 'decentralized credit ecosystem,' converting long-term contribution records into ecological credit scores, further enhancing long-term contribution value. This attribute of 'solving current data compliance and long-term contribution pain points + laying out future data value ecology' gives Caldera a unique competitive edge in the L2 data value deepening phase.
In summary, Caldera releases data value through the cross-domain data compliance circulation protocol, while recognizing long-term contributions through the time-sequencing rights confirmation system. Although there are fluctuations in the short-term market, data such as '8 million compliant records, 1.5 million time-sequenced confirmations, and 25,000 long-term contributors,' combined with the upgrade of $ERA from 'functional token' to 'compliant data value medium,' makes it hopeful to become the 'core of compliant data value' in Ethereum RaaS, opening up a new ecology of 'data can circulate compliantly, and long-term contributions are richly rewarded,' with long-term value being scarce and sustainable.
