For the life of me, i don't understand "blockchain exchanges"

[kaiser11]

why fill the blockchain with unnecessary garbage that bloats the size of the blockchain when you can put your "stuff"  in your own database and be done with.
Blockhain should be about Bitcoin moving from one wallet to the other, instead of throwing all the troubles of the world as if this was a global recycle bin.

In my view - Traders want and need service.  it is immaterial whether this service is based on a database or on the blockchain

[Amph]

this is why something like saidchain will be needed, to put there all the unnecessary and superfluous things, without wasting space on the blockchain

You're saying there's something in the works ?

[CryptoTrout]

there are lots of projects looking for side chain alternatives

There are a lot of reasons behind, like the onchain gambling site, some kinds of campaign, sending message,  begging for donation and faucet payment etc.

But there are other way to achieve these without using the blockchain.
using the blockchain and bloating it affects the ability of people to host the blockchain on their computers, the reduces the overall distribution of the blockchain as a direct result of this misuse
