In plain words

Prioprepare helps creators establish proof of work ownership by generating a cryptographic hash of their documents and embedding it in bank transfer message fields. This creates a timestamped record at a financial institution that can support claims of authorship and priority. The tool is designed for inventors, authors, artists, and scientists concerned about protecting their intellectual property when sharing work.

Prioprepare

As an inventor, author, artist, scientist or other creator, you may fear that distributing your work creates a risk that others replace or deny your authorship. Here is a simple solution to this problem: Compute a cryptographic fingerprint from a document and copy it to the text fields of a bank transfer . With such a fingerprint (hash value) stored at a bank there is evidence of the existence of the content of a document at a certain point in time. This can be used to e.g. support a proof of priority. Text fields for SEPA bank transfers offer 140 characters for a message. Some online web interfaces implement this not with a single field, but with two lines of 70 characters or four lines of…from rschoenm.github.io

    Hi HN, I built BulkShare (https://www.bulkshare.cloud/) because I was tired of sending clients generic links from services like Dropbox or WeTransfer. It always felt a bit unprofessional and disconnected from my brand. I wanted a way to share files that looked like they were part of my own site, hosted on my own domain, without having to set up a complex server or manage cloud storage buckets myself. The idea is pretty simple: you connect your own domain or a subdomain (like files.yourdomain.com), and you can immediately start uploading files or entire folders. You can keep…
