Pro. We need bigger blocks.

cryptograffiti.info works better for me, because it doesn't break the sentences.

No, we do not break sentences. Data is stored via OP_HASH160 exactly the way you enter it, it's not possible for a single bit to be different.

Some sites like cryptograffiti chooses to break up scripts, when there is no accepted standard to do so (it should be joined together). Rather, they invented an arbitrary jigsaw-like format for re-arranging scripts.. that is going to look gibberish if you do it the traditional way (join output scripts).

That's why they're not suitable for archival purposes, you have to rely on their website for their esoteric ordering algo. If you 'cat {the blockchain} | string -n 20', you'll get unsorted gibberish with anything encoded using their service. If you use blockchain-db, you get them in order Smiley

Furthermore, their service can't force the change address to be at the bottom. There's gibberish in the middle of these messages, and that makes file storage impossible. We've patched our bitcoin core node to always place the change output at the end, and the OP_HASH160 is paddled with terminal 0x00s so you actually know where the file ends.

Also, Blockchain-DB lets you store raw bytes, eg binary files, encrypted files, small images, compressed audio files, etc. Smiley

As you said, blockchain.info notes are centralised and are not suitable for archival.

TL;DR: Blockchain-DB.com is the only archival-grade service that implements message embedding via OP_HASH160 correctly.
3  Bitcoin / Project Development / Blockchain DB: Store any data on the blockchain, 100% uncensorable. on: February 03, 2015, 01:24:41 PM
Blockchain DB allows you to leverage the blockchain as a redundant message / data archival system. Just enter your text (or raw bytes, if you preer to store data), pay the fee, and it will be embedded into the blockchain.

It uses OP_HASH160 so the data cannot be pruned or ultrapruned - guaranteeing that your data will forever remain on the blockchain. It's also completely uncensorable.

Is that not classed as hacking, do you have permission to add data to the blockchain?
Just asking.
Nobody owns the blockchain, just like how nobody owns Bitcoin. Anyone is free to use bitcoin and the blockchain. When you make a transaction, you are adding data to the blockchain.

Blockchain-DB.com is similar, except it allows you to add meaningful data to the blockchain - to be distributed among tens of thousands of nodes, forever.

Blockchain-db.com is a new service that allows you to store text messages or data on the blockchain.

For just 0.001 BTC, you can replicate a 20 byte message to tens of thousands of hard drives around the world. They cannot be pruned, and will be permanently stored on the blockchain. Storage is as cheap as 7897 satoshis per 20 bytes.

Use cases
* Express your love, marriage, or venegeance in a form that will last forever.
* Timestamp a document by publishing its hash, which will be associated to a block and hence timestmap.
* Write a short autobiography and be remembered forever.
* Store your cold storage private keys in encrypted form.
* Publish and distribute an encrypted message, with an associated dead man's switch to release the key.
* Release and immediately distribute sensitive documents, making them uncensorable.
* Leave a time capsule for future historicians, hundreds or thousands of years from now.
* The possibilites are endless.

I received the following 2 screenshots from a source. Obvious throwaway.

https://coinbase.com/lunar





I am not entirely sure of the authenticity (my source does not work for Coinbase, but he has contacts), although this certainly explains the 50% flash rise in LTC.
