Greetings from the blockchain

The blockchain is an amazing piece of technology. And we’re proud to be part of it. Forever. Through a series of transactions we became the first brand to place an ad in the blockchain. Why? Well, we love finding new ways to use emerging technology. So we decided to have a little fun and plant our flag. Okay—technically, we embedded it.

Transaction ID.........................................OP_RETURN

How we created a first in 68 transactions


At its most basic level, the blockchain is a public ledger that logs transactions. A record of events, if you will. So how did we turn that into an image? With a part of the blockchain called OP_Return, which functions like the memo space on a check, simple messages and characters can be placed within transactions on the blockchain. By linking 68 individual transactions, with 80 characters per transaction, we were able to create the larger image.

See it for yourself


The transactions are live in the blockchain now. So, when you click on any one of the transaction IDs, you’ll be linked to a blockchain explorer, where you can see the details of the individual blockchain transactions that make up the message.
