DePin

Delve into the background of the OORT track, project operation logic, and more, to glimpse the project's prospects and the opportunities and challenges for the AI+DePIN track in 2024.

This article reviews the process of IoT devices generating data, storing data, and rolling up to the blockchain. It also introduces the DePIN infrastructure platform, which can help project teams quickly launch DePIN application projects. DePIN utilizes blockchain for incentive distribution and token allocation, requiring the use of public-private keys to generate and verify physical proof of work. To prevent Sybil attacks, DePIN device manufacturers monopolize the generation authority of identity information and expose malicious behavior through social consensus. DePHY provides DID authentication services to ensure the credibility of data sources. DePHY also provides a co-processor to listen to finalized messages on the message network and perform state transitions. Both DePHY and IoTeX choose to collect data off-chain and then roll up to the chain, with DePHY focusing on decentralized data availability layers and IoTeX emphasizing binding handlers to different events.

Last year, the narrative of DePIN ignited the trend of Helium (Mobile). Although DePIN seemed unremarkable during the “Bitcoin Bull Market,” it still brought surprises to the cryptocurrency industry. At the recent ETHDenver 2024 conference, DePIN was listed as a hot track, and now the success of io.net has once again stirred up the DePIN narrative.
