The service let's you easily write short text message in the OP_RETURN field of a bitcoin transaction.
One message every hour is free or you can always pay in bitcoin.

"You are not able to stop the wind..."

Do you like it?

Feature added: Full text search

Is there somewhere a list of people that have used the "right to be forgotten" ?

Bump.

Feature added: message are sized by attention gained (views, recent views, likes and replies)

I saw that it is possible to search the op_returns here on this Block Explorer: https://www.smartbit.com.au.

You can try to find if you or one of your friends are cited on an op_return. (or if the eternitywall goes offline)

Just released widget code to show Eternity Wall message on third party web site

Very interesting... i shall try this out and see where it goes from there...

ONE MESSAGE FREE .... FREE OMG IT'S FREE

Official android app (it's still in beta):
https://play.google.com/store/apps/details?id=it.eternitywall.eternitywall

wow, it is a really valuable app, thanks dev, i'm going to tell friends about it

This is an interesting app, but I'm lost as to something. One of the messages deals with this transaction:

https://blockchain.info/tx/69c6c741d4a3259ad94d094ddb470f41b78bca5f34db1a8a7d5ab79a5bbbc6f9

"Unable to decode output address"

That seems really weird.

We are proud to announce Eternity Wall now supports signed messages! Because anonymity is an highly desirable option, but you could want to have verifiable credit for what you write. You could use a nickname or your real life name, the important thing is that no one could write with your name. It’s not an account in a traditional way, actually, you are not registering in any particular server and you are not asking anyone permission... more...

Play store: https://play.google.com/store/apps/details?id=it.eternitywall.eternitywall

Source on github: https://github.com/RCasatta/EternityWallAndroid

Web site: http://eternitywall.it

It works also with https://play.google.com/store/apps/details?id=org.torproject.android to hide your ip.

You need to enable it on all connections.

Nice idea for sure, but How do I do to post messages? I cannot figure out how to do it, cannot type in the field or see any button to do it or something.

And how is that paid service? Perhaps you need the app to do it?

The messaging app looks nice. I want to see soon the video messaging app with blockchain. Will OP_RETURN support video broadcasting? Are we not up to the mark for that? How much will it cost to send additional messages? How can I show others that I added message to the eternitywall and it is living in the blockchain and it will live forever. Do I need to send money to the address to include the message in the transaction? It seems I know something right, but something not.

There are many ways to post messages:
from the web site (http://eternitywall.it) clicking the write button. There is globally one message free every hour or you can always write paying in bitcoin.
from the android app (https://play.google.com/store/apps/details?id=it.eternitywall.eternitywall) by clicking the plus "+" floating button.
If you want to write nominal message (not anonymous) you need to create an account in the app (in the user tab) and deposit some milli bitcoin to write a few messages.



Space in OP_RETURN it's expensive, in theory it's possible to store data but it's not practical.
Message cost about 0.2 milli bitcoin
In every page of a message, there are links to third party block explorers where you can see the same message, proving that it's in the blockchain
