why is writing onchain important?

!flux11 Proof of existence. The subconscious desire for immortality. The opportunity to experiment with cutting edge technology at the forefront of human ingenuity.

Writing data onto the blockchain is important because it ensures all ideas, good and bad, persist. When the good ideas take root and grow, we can always trace it back to when that idea was planted for generations to come. When the bad ideas are proven as such, we can always point back at it and laugh.

!flux11 There are various reasons why writing on-chain might be/is important:
To proof that something was written at or before a certain moment in time. It could be a cheap solution to current patent offices (which are expensive mainly to "guarantee" a certain level of trust).
To build a long-term future-proof profile about who someone is so that future generations can learn who that someone was.
To assure we still have access to our data/work in case the Treechat team decides to move on and go for pina coladas on a sunny sandy beach.
To hold accountable spreaders of misinformation and this as an alternative of "prebunking" (which leans IMO close to dictatorship).
To assure that a certain file/dataset/source comes from a provable source and shows that it's content was not changed. Recently we have seen a lot of movies/books that were edited because of "no longer appropriate" with which I don't agree! One should see/read those resources through the eyes of that time period. What's next? Overpaint all Ruben's works because "nude" is no longer tolerated?!? Where do we draw the line?
To be able to have access to your data, even as a total outcast, by means of your own software.
To have a platform without any bias or preference: a pure FIFO/LIFO system that shows post in a chronological order
To assure that your data is stored in a decentralized way in order to protect from one-point-of-failure.

History preservation amongst other things

It’s both a privilege and a duty to document what is happening as it happens, and write it on chain for those who come after us to know the truth. Fortunately for us, Treechat has made that possible (and very pleasant) and so we should use it at every opportunity.

Having a record that doesn't depend on companies, governments and censorship would be amazing.
Unfortunately pruning is in the way.
