An NFT on OpenSea Can Steal Your IP Address

An NFT found on the OpenSea marketplace can steal visitors’ IP addresses, according to a repot from Motherboard.

But here, an outside third party—the NFT seller—is able to gather information themselves on the people viewing the NFT, potentially without them knowing.

What is Web3? Explaining the Technology Stack in This New Ecosystem

A recent report from Coinbase examines the web3 stack, or the various protocols and blockchain technologies that make up the ecosystem.

Where a third party like Facebook owns your identity and data in Web2, your identity in Web3 can move fluidly between platforms without your data being captured and monetized by service providers. While Web2 apps are centrally controlled, tokens in Web3 grant users the right to help govern the services they use, representing a form of ownership in the platforms themselves.
