Witness History in Every Line
The Bitcoin blockchain holds more than transactions, it's a time capsule of human moments: love notes, declarations, inside jokes, dreams, protests, and farewells.
BitCodex.app lets you explore thousands of real messages inscribed forever into Bitcoin's ledger. Every time you refresh, you uncover another small piece of blockchain history.
Press to discover more messages, or your own message for future generations to find.
Why BitCodex?
BitCodex makes blockchain inscription easy for everyone... no downloads, no keys, no coding. Just your message, a small payment, and the power of Bitcoin.
What is the Blockchain
The blockchain is a global record of Bitcoin transactions, shared and stored on tens of thousands of computers around the world. It tracks every entry in a way that anyone can verify, but no one can change. Once something is written to the blockchain, it's there for good. No single person or government can alter its contents. It may be the most enduring digital record humans have ever created.
How It Works
BitCodex takes your message and embeds it in a Bitcoin transaction using the OP_RETURN field, a space designed for attaching small pieces of data. Once confirmed, your message becomes part of the blockchain's permanent history, likely to be preserved and explored for generations to come.
Verified on the Blockchain
You can verify the message embedded in this transaction on any public blockchain explorer. Click the preview to open the actual transaction page. Look for the OP_RETURN field.
