The HBIT Data Cloud is a decentralised data storage system.
In addition to keeping a record of HBIT transactions, the blockchain can also be used to store user-defined data. All forms of data can be uploaded to the HBIT blockchain, providing a secure (and, if desired, permanent) method of storing, retrieving and publishing information. HBIT Messaging makes use of this ability to embed data in the blockchain, and the Data Cloud can be seen as an extension of the Messaging system.
One of the most important features of data storage on the blockchain is that the HBIT blockchain is a permanent and immutable record that provides a tamper-proof time stamp. This allows for legal records (such as contracts) to be embedded in the blockchain, with absolute certainty about the time at which they were created.
A single data item is currently limited to 2MB on the public blockchain. Only the The sha256 hash of the data is stored on the blockchain as proof of existence. The data itself is pruned after several days.
EXTEND CLOUD DATA
The files sent on the Blockchain remain available for about 7 days, then they are deleted to keep the Blockchain clean and light.
It is possible to extend the duration simply by clicking on Extend, you pay a commission for sending it to the Blockchain, equal to that required to upload the file again.
Anyone can extend the duration of a file's stay in the Blockchain, but whoever uploaded it will always remain the same user.
