Tezos is a platform for decentralized applications (DApps).
Tezos is the name of the platform, and the currency unit is XTZ.
Tezos has a self revising feature that allows it to upgrade itself without letting it hard fork (split by a system update). In traditional blockchain projects, new blockchains that are updated to solve problems are not compatible with the existing blockchains, and there is a risk of having to develop a system from scratch.
The Tezos project is a next generation project that is attracting a lot of attention from many people because of its approach of not requiring a hard fork to update the system.
