# Why the need for a blockchain?

Blockchain is part of our technology stack and is used for a number of key reasons:

* **Trust:** Transactions validated “on-chain” cannot be changed later. This provides an elevated level of transparency and immutability.
* **Efficiency:** Smart contracts enable the replacement of many bureaucratic and administrative layers, which makes the solution much more efficient.
* **Digital ID:** Enables millions of users to obtain a digital identity, which alongside connectivity is vital to banking the unbanked and bridging the digital divide.
* **Sharing economy:** Node owners and operators are rewarded automatically through the tokenomics of the blockchain, enabling rapid growth of the network.
* **Self-data governance:** Gives users privacy and control over their own data.
* **Community:** Enables distributed ownership of our infrastructure, allowing for scalability and decentralisaton.
