# Trust through blockchain

* Decentralization: data is not controlled by a central entity, but distributed over a peer-to-peer network. This prevents the monopolization of IoT data by cloud giants.
* Immutability: transaction history is immutable once recorded on the blockchain. Data cannot be falsified, modified or deleted, reinforcing trust.
* Trust: the blockchain's cryptographic and consensus mechanisms guarantee the integrity of transactions without the need for a trusted third party.
* Transparency: all network participants can transparently verify and audit transactions on the public blockchain.
* Resilience: the distribution of data across multiple nodes makes the blockchain resistant to censorship and failure. There is no single point of failure.
* Security: end-to-end encryption and digital signature techniques secure transactions against cybercrime.
* Sovereignty: users retain full control over access to their data, thanks to cryptographic keys.
