The BIP110/Blake chain finally has a use case: media publishing!
Using BcashJr Wallet, which also lets you easily split your BTC and Blake UTXOs, you can now publish images using the BPUB protocol.
BPUB doesn’t use Ordinals inscription envelopes. It embeds file data into public keys within multisig scripts, then reveals those scripts in transaction witnesses. That lets it publish images despite BIP110’s censorship.
Pick an image (resize and optimize it first), select the BLAKE coins to fund it, review the fees, and publish. Unused funds return to your wallet as change.
