Does anyone know of another service like
www.cryptograffiti.info that posts to the Bitcoin Core blockchain? I would like a similar simple interface if possible (to post a message and maybe a photo!). When researching, all articles pointed to Cryptograffiti.info but I failed to find notes or comments confirming it no longer supported BTC core and had moved on as BTC forked.
You can "
post" your messages using a "
text-to-HEX converter" & Electrum, and it will be saved to Bitcoin's blockchain after getting a confirmation, but the transaction can already be seen on blockexplorers right after it was broadcast.
Although, you won't be able to see the messages directly like in that website. You'll have to convert the hex string into txt, image or other formats manually.
There are limitations though, it will be non-standard and wont easily propagate nor mined if it didn't follow any of the standard rules:
Standard-transactions |
Non-standard-transactions.
Like converting an image into hex, the size will not even fit the default relay size of 83bytes.
TL;DR: In comparison, that website is using BitcoinSV's chain that has a maximum OP_RETURN relay size of 100kB (
just because?) while Bitcoin's default standard limit is 83 Bytes.
In short, something like that site that can 'casually' post long messages, codes, images, etc. using Bitcoin's [
BTC] Blockchain isn't possible.
(Call bitcoin: Bitcoin, not Bitcoin Core, it's the full node client's name or a name of another misleading fork - BTCC).
(Do not try doing this in the mainnet without sufficient research, use testnet for your tests).
