Just wondering who is creating these transactions: https://blockchain.info/tx/db195e4bfcfb3cc6d47f8d6231cb59e543c31e01d196d557457bca0fa5c1aba0 ... 20402 byteshttps://blockchain.info/tx/24560b7fbd172ff0e95dc8cc0af88a332e3be016a7f2aa35e432fd8beac3ed46 ... 63433 byteshttps://blockchain.info/tx/ce8c8d8154546bdbe28ff10dc4044a63cf11758839362c94dc6b9a99d55af3e5 ... 56905 bytesand so on. These transactions store some text data in blockchain with P2SH technique. It is not too difficult to create a tool to get data as a plain text from these transactions (but I do not have interest to do it) You can download them as binary and view in hex editor. You will see something like: 0000000140: 20 20 20 20 20 20 20 20 │ 00 49 00 59 6F 75 6E 67 I Young 0000000150: 20 41 6D 65 72 69 63 61 │ 6E 73 20 77 68 6F 20 6C Americans who l 0000000160: 65 61 76 65 20 74 68 65 │ 69 72 20 67 72 65 61 74 eave their great 0000000170: 20 62 69 67 20 68 6F 6D │ 6F 67 65 6E 65 6F 75 73 big homogeneous 0000000180: 20 63 6F 75 6E 74 72 79 │ 20 61 6E 64 20 76 69 73 country and vis 0000000190: 69 74 00 45 00 73 6F 6D │ 65 20 6F 74 68 65 72 20 it E some other 00000001A0: 70 61 72 74 20 6F 66 20 │ 74 68 65 20 77 6F 72 6C part of the worl 00000001B0: 64 20 74 79 70 69 63 61 │ 6C 6C 79 20 67 6F 20 74 d typically go t 00000001C0: 68 72 6F 75 67 68 20 73 │ 65 76 65 72 61 6C 20 73 hrough several s 00000001D0: 74 61 67 65 73 20 6F 66 │ 00 45 00 63 75 6C 74 75 tages of E cultu 00000001E0: 72 65 20 73 68 6F 63 6B │ 3A 20 66 69 72 73 74 2C re shock: first, 00000001F0: 20 64 75 6D 62 20 77 69 │ 64 65 2D 65 79 65 64 20 dumb wide-eyed 0000000200: 61 73 74 6F 6E 69 73 68 │ 6D 65 6E 74 2E 20 54 68 astonishment.

I wish this stuff didn't happen in the blockchain, the thing is bloated enough.

You may wish anything. But this is consensus code for accepting such things

Pushing texts to blockchain is some kind of vandalism imho

this is ugly. I mean, obviously there will always be ways to embed data into the blockchain; but if one has to split them between a long chain of transcations, and also encode them somehow inside, then the information (and effort) needed to extract the data is non-neglible, so one can ignore it.
But the possibility of pushing large chuncks of plain text in a single transaction looks like a bug to me.
Is it possible to make this kind of things non-standard, without compromising the expressive power of the script? Like, the way those SASSAMA/ Bernanke ASCII pictures were put was somehow "outlawed" later on.

It is a feature, not a bug If we disallow this feature (we can not, but hypothetically), somebody would create a tool which posts large data chunks as several small (chained or parallel) transactions.

It is a feature, not a bug If we disallow this feature (we can not, but hypothetically), somebody would create a tool which posts large data chunks as several small (chained or parallel) transactions. Like I said, if it requires a specialized tool to get it out, then it can be ignored. I mean, the blockchain probably contains your username already: there's an A at some place, M at some other, etc. I can publish a tool that finds it in the blockchain, but the tool would be longer than the piece of data in question (your username). large chunks of plaintext, on the other hand, is a different matter. why are you saying it cannot be disallowed?

Because this is consensus code. It is too hard to change it, isn't it?

Because this is consensus code. It is too hard to change it, isn't it? I suppose it depends on how significant the change. is Whether any used or potentially useful cases are affected. If the change is mostly techincal then nobody will care. Look at BIP 66 voting that is going on now. Nobody seems to care very much.

There is only one thing everyone cares. Profit of investments calculated in fiat currency. So, you are right: nobody cares of the size of blockchain and the number of utxo and malleability and so on while bitcoin gains profits.

* The guy who sent the transaction paid the fees for it. Actually, well above the minimum fee required. * Why should his data be rejected and not color coins, stealth addresses, or any other non bitcoin data? Do we start judging what should be and shouldn't be allowed? * The data can be pruned since it's part of the sigscript.

He paid for it only to a miner who find block. I am not sure that keeping ( 100 kilobyte ) x ( several thousands fullnodes ) x ( unknown time ) costs less than a couple of dollars. * Why should his data be rejected and not color coins, stealth addresses, or any other non bitcoin data? Because the majority can do anything. Do we start judging what should be and shouldn't be allowed? Have we stopped doing it? * The data can be pruned since it's part of the sigscript.

Majority of whom does not agree with which proposal? I am just asking questions and reading opinions.

Does this mean that Bitcoin is pretty vulnerable against vandalism? What happens if someone is pushing giga bytes of text into the blockchain? Does text pushing to the blockchain cost more than a normal transaction? Pushing texts to blockchain is some kind of vandalism imho
