For all smart contracts that rely on external data, the balance between data timeliness and acquisition costs has always been a core pain point. In the DeFi field, delayed data updates can directly lead to liquidation failures and transaction execution deviations; while excessively pursuing high-frequency updates can trap applications in a 'high-cost operation' dilemma due to soaring on-chain Gas fees. Innovatively adopting a dual mechanism of data push (Push) + data pull (Pull) and combining it with an efficient two-layer network architecture has successfully solved this industry problem.
The data push (Push) mechanism is tailored for scenarios sensitive to real-time performance, such as high-frequency trading, automated clearing systems, and instantaneous price-triggered contracts. When the price of off-chain data sources (such as mainstream exchanges and aggregated market platforms) fluctuates beyond preset thresholds, APRO's distributed verification nodes quickly complete data verification and consensus through AI algorithms, subsequently actively pushing authoritative data to on-chain smart contracts. The entire process is completed at millisecond speed, ensuring both the timeliness of the data and security through multiple node validations, allowing smart contracts to accurately respond to market changes.
The data pulling (Pull) mechanism focuses on cost optimization and on-demand usage scenarios—suitable for applications with lower real-time requirements (such as daily settlement, periodic audits), or with uncertain data call frequency. In this mode, smart contracts do not need to continuously receive data updates; instead, they can actively request data from the APRO network at specific times based on their own business logic, incurring a one-time on-chain transaction fee only when obtaining data. This 'on-demand calling' model significantly reduces unnecessary Gas expenses, making it especially suitable for small to medium-sized projects or low-frequency data demand scenarios, achieving a balance between cost and practicality.
APRO's dual-layer network architecture (high-performance off-chain validation layer + decentralized on-chain reporting layer) provides the underlying support for two mechanisms: the off-chain validation layer ensures that the pushed/pulled data is authentic, reliable, and unaltered through a distributed node cluster and AI verification algorithms; the on-chain reporting layer is responsible for the final on-chain data and record preservation, ensuring decentralization. By intelligently adapting to two data transmission modes, APRO's $AT network can meet the rigorous demands of high real-time scenarios while providing cost-effective solutions for cost-sensitive applications.
The flexibility of this 'dual-mode + architecture empowerment' is precisely the core competitive advantage that #APRO distinguishes it from traditional single-mechanism oracles, making it a versatile oracle solution that covers diverse scenarios.
