Harnessing the open source EOSIO blockchain software, Voice benefits from the inherent characteristics of blockchain technology, which promote security and auditability to enable trusted and transparent social interactions.
Part of the benefit of blockchain is that every action on the blockchain is recorded as a transaction making it auditable. However, the content in that transaction is not recorded - just the action. So if you create a post on February 14, 2020 at 9 a.m. about why cats make the best pets, the blockchain records auditable proof of what you posted and when, but the content of the post - the title, text, images, etc. are not recorded on the blockchain.
If you choose to delete a post, or comment, your content is gone, but it is possible to prove that you posted that specific content, at that specific time.
