How to import from/export to Arweave

Export to Arweave makes your contents permanently accessible to everyone.

Arweave utilizes blockchain technologies and provides permanent storage at a reasonable price.

You may like to export the note to Arweave when you would like the notes to be immutable and be hosted on a different network accessible to everyone.

Consider exporting to Arweave when publishing sensitive, controversial, or anything not intended for anyone, including yourself, to change.

You can also import notes that you have exported from HackMD to Arweave.

HackMD only supports export to and import from Arweave from a desktop due to the complicated steps.

Notes

• HackMD has transferred the content of the note to Arweave network once the export is successful. However, it will take some more time, depending on the transaction amount at the moment, before the content is technically "on chain," for it must go through validation and other processes.
• If you'd like to inspect the content on the Arweave network, you will have to get the transaction hash, which can be copied from the export modal or on the share page.
