[quote=“pillow, post:10, topic:2977”][quote=“caribou, post:9, topic:2977”][quote=“Sunny King, post:2, topic:2977”]Yes, but it’s probably not directly competing with bitmessage, as I understand, in blockchain based solutions, messages are stored in blockchain/sidechain, so there is different limits on scalability.
Also, for sidechain application it probably wouldn’t involve a PPC transaction. The message is contained inside a sidechain transaction only.[/quote]
According to Bitcoin sidechains whitepaper, both parent chian and sidechains add a transaction for each transfer. This willn’t solve the issue of Bitcoin blockchain bloat.[/quote]
I’ve not read the whitepaper, but my guess would be that they are referring to the transaction where the coin is “moved” from the main chain to the side chain. Then on the side-chain all kinds of total craziness can happen, like a 10 seconds confirmation side chain, zero-proof stuff (which also have bigger messages) and all that kind of stuff. This would happen on the side chain and not be bloating the main chain. Then there would be this transaction where the coin is moved back from the side to the main chain and when its crossing back, the coin would leave all that bloating history behind so to speak.
Disclaimer: I’m totally just making this up, I’ve not read the whitepaper and this is all just pure guess work, based on me thinking how it kind of “have to work” and not how it actually works.[/quote]
In P6 of Bitcoin sidechain whitepaper:
"Our proposed solution is to transfer assets by providing proofs of possession in the transferring transactions themselves, avoiding the need for nodes to track the sending chain. On a high level,
when moving assets from one blockchain to another, we create a transaction on the first blockchain locking the assets, then create a transaction on the second blockchain whose inputs contain a
cryptographic proof that the lock was done correctly. These inputs are tagged with an asset type, e.g. the genesis hash of its originating blockchain.
We refer to the first blockchain as the parent chain, and the second simply as the sidechain."
