Many other projects, too, share the topic of Personal Data, Big Data, and Digital Advertising like AIRBLOC protocol. However, AIRBLOC protocol clearly distinguishes itself from the following projects.

Project title	Major subject of decentralization	AIRBLOC's major subject of decentralization	How AiIRBLOC protocol different itself
Basic attention token	User Attention & ad exposure	personal data	The subject of decentralization is different. BAT uses browsers to decentralize personal interests data and its corresponding Ad Exposure, while AIRBLOC is decentralizing anonymized personal data. AIRBLOC does not operate an independent browser nor advertisement placements. Therefore, AIRBLOC’s project yields no relation to personal interests.
AdEx	ad exposure	personal data	The subject of decentralization is different. AdEx attempts to decentralize the whole process of Ad Exposure with decentralized advertisement placement, from the ad publisher to the advertiser. But such attempt is unrealistic since it requires having large set of advertisement placements or a very efficient use of the advertisement placements via machine learning or AI. AIRBLOC basically aims anonymized personal data for decentralization, not advertisement placement transactions. AIRBLOC first decentralizes anonymized personal data to create data market, and have other advertising platforms participate in this market voluntarily by purchasing personal data for effective advertisement. Naturally, decentralization of the ad market is formed.
Datum	Personal data	Personal data	AIRBLOC allows Apps to engage in surrogate data sales via DAuth & SDKs. Also, with the launch of Data Marketplace can be added to the existing Airbridge dashboard and instantly commercialized.
Ocean Protocol	Any data or Data set	Personal data	AIRBLOC does not deal general data such as the acquisition and trading of schema data for the data market and development of AI like Ocean Protocol. In particular, Users always become a primary data producers on AIRBLOC, not large organizations or government data sets.
DataWallet	Personal Identity Data	Personal Data	AIRBLOC collects data related to the User-level identification and uses them only for the purpose of Data Reliability Evaluation. Rather, it is possible to more accurately assess the Users’ reliability on AIRBLOC by linking with a project that builds a decentralized identity system for the individual User, such as DataWallet.
