Immortal
A simple app for saving web pages to Bitcoin, the content or its hash, as a tamper-proof record.
Immortal (Immortal.sv) was a fun side project from early 2019. The idea was to archive the world’s information on-chain: paste a link, and it posted a snapshot of the page, or a hash of it, to Bitcoin. That created a record nobody could quietly change later, in an app anyone could use in a few seconds.
I talk about it in Building on Bitcoin #1.
