In the past two years, on-chain projects have become increasingly complex, but the old problem remains: how can we reliably know what is happening in the 'off-chain world'? It seems that the oracle space has long been dominated by a few leading players, and traditional solutions have repeatedly exposed their shortcomings during extreme market conditions: feeding prices too slowly, overly centralized data sources, and crude cleaning logic. When things go wrong, it’s either the liquidation mistakenly targets the wrong person or DEX liquidity is skewed by a series of marginal quotes. New players like APRO have emerged, aiming at this 'homework not done yet' old track. It is not simply creating another price center; rather, it breaks down security into layers, controlling the entire process from data collection, transmission, aggregation, to on-chain publication—ensuring 'who has the opportunity to commit wrongdoing, how high the cost of wrongdoing is, and whether wrongdoing can be quickly detected'. Traditional oracles often focus only on the 'instant price' that matches trades, while APRO cares more about the real trading volumes and order depths behind different exchanges and liquidity pools, filtering out those obvious 'spike' ghost data. It prefers to sacrifice a bit of millisecond-level speed for overall reliability, which is a choice that may not cater to emotions but is friendlier to protocol developers. Interestingly, in its channel design, it does not simply follow the brutal path of 'more nodes equals more decentralization' but emphasizes the professionalism of participating nodes and geographical and architectural dispersion, avoiding a situation where a large number of nodes appear on the surface but are actually running on one or two cloud services, resulting in the embarrassing scenario where the entire network goes offline if a certain data center loses power. To put it somewhat bluntly: in today's world where 'narratives prevail over code', projects like APRO that are still refining their underlying infrastructure instead of just telling stories are actually quite 'unpopular'. However, when market volatility hits, many will find that avoiding a mispriced liquidation may be worth more than a pile of speculative airdrop opportunities.
