Do transaction messages bloat the blockchain?

[jonoiv]

as the titles says!

If there is coin X which is identical to coin Y but with the added feature of sending messages with your transaction, which is best?

Obviously coin X looks best but does the block chain get bloated by the messages?  will it eventually slow the coin transactions down?

Coin Y (no transaction messages)

Coin X (with Transaction messages)

For sure,
the block chain of coin X will be bigger than the blockchain of coin Y.

Imagine a coin like worldcoin with block every 15 seconds and a message in each transactions !

You would think so, but in reality, the transaction message is so small compared to the size of a transaction.

Here's some real statistics from Florin coin (the original transaction message coin).

Code:

mysql> select avg(size) from tx where (message is NULL or message = "") 
+-----------+
| avg(size) |
+-----------+
|  979.2556 |
+-----------+
1 row in set (0.07 sec)

mysql> select avg(size) from tx where (message is not NULL and message != "");
+-----------+
| avg(size) |
+-----------+
|  501.6539 |
+-----------+
1 row in set (0.04 sec)

Surprisingly, the transactions with messages happens to be smaller on average than those without.

two different opinions there ! hmmm   

do either of you think that it will eventually slow transactions down and the confirmation speed ?

this example is both florincoin, yes?

if so then surely that fact that the database has an extra field will bloat it ? 

for example the field is empty vs no field at all.  surly the coin without it will be smaller in the database.

I already responded to this question for Neocoin. Messages have a small size relatively to the size of a block in the chain, the current bitcoin block size is 500KB.

Websites that spam the network with a tremendous volume of microtransactions like satoshiDice are much more dangerous for the blockchain.
