Jeff Garzik: Sidechains a Better Bitcoin Scaling Solution Than Lightning Network
http://coinjournal.net/jeff-garzik-sidechains-better-bitcoin-scaling-solution-lightning-network/“It might be a sidechain that is a far, far better solution than [the Lightning Network].”
“The economics are still very, very open to question — whether you’re going to want to commit BTC simply to have access to instant payments . . . not everyone can even afford that.”
“I think that [sidechains are] a better solution, but all the things I just said about Lightning apply to sidechains as well. It’s an immature, unknown technology that hasn’t been rolled out into production, so you don’t want to bet the universe on one particular direction — even the direction I think is the best.”

http://bloq.com/IMO unobtanium is a working time tested bitcoin side chain. (i know technically not a side chain but merge mine tech)
IMO ... in time ... uno can market itself as a bitcoin side chain.
IMO ... no one outside of the realm of devs/programmers cares about the formal technically definition ... to the general public bitcoin side chains would be the ledgers attached to the bitcoin network (aka MM).
My understanding of The Lightning Network
TM:
-6 of the biggest baddest exchanges
-big money & suits & lawyers
-cartel (but don't tell anyone)
-everyone will use it because we called it The Lightning Network
TM-now deposit all your
BTC on a Cartel Exchange so you can send Lightning fast!
The sidechains ideas is this:
Send your Bitcoins to a specially formed Bitcoin address. The address is specially designed so that the coins will now be out of your control… and out of the control of anybody else either. They’re completely immobilized and can only be unlocked if somebody can prove they’re no longer being used elsewhere (I’ll explain what I mean by this in a minute). In other words, you’ve used the core bitcoin transaction rules I described above to lay down a specific condition that the future owner – whoever it ends up being – needs to fulfil in order to take control
Once this immobilisation transaction is sufficiently confirmed, you send a message to the other blockchain – the one you were wanting to use. This message contains a proof that the coins were sent to that special address on the Bitcoin network, that they are therefore now immobilized and, crucially, that you were the one who did it
If the second blockchain has agreed to be a Bitcoin sidechain, it now does something really special… it creates the exact same number of tokens on its own network and gives you control of them.
So it’s as if your Bitcoins have been transferred to this second chain. And remember: they’re immobilized on the Bitcoin network… so we haven’t created or destroyed any…. Just “moved” them.
You can now transact with those coins on that second chain, under whatever rules that chain chooses to implement.
Perhaps blocks are created faster on that sidechain. Perhaps transaction scripts are “turing complete”. Perhaps you have to pay fees to incent those securing that sidechain. Who knows. The rules can be whatever those running that sidechain want them to be. The only rule that matters is that the sidechain agrees to follow the convention that if you can prove you put some Bitcoins out of reach on the Bitcoin network, the same number will pop into existence on the sidechain.
And now for the second clever part. The logic above is symmetric. So, at any point, whoever is holding these coins on the sidechain can send them back to the Bitcoin network by creating a special transaction on the sidechain that immobilises the bitcoins on the sidechain. They’ll disappear from the sidechain and become available again on the Bitcoin network, under the control of whoever last owned them on the sidechain.
Drivechain - The Simple Two Way Peg
With sidechains, altcoins are obsolete, Bitcoin smart contracts are possible, Bitcoin Core and BitcoinXT can coexist, and all hard forks can become soft forks. Cool upgrades to Bitcoin are on the way!
http://www.truthcoin.info/blog/drivechain/"With sidechains, altcoins are obsolete" ... oh i get it now ... all this fancy complicated confusing talk about some vaporware drivechain sidechain Lightning network ... boils down to jealousy and greed ... BTC Maximilst.
UNO can be a sidechain, in fact any alt can be a sidechain. And it is less about code wizardry, and more classical escrow/trustee business. The solution is so simple even i can figure this one out
Imagine thus:
-there is this company call "UNO'r'us"
-you send them 1 bitcoin and they send you 100kg of UNO
-now you can send TX faster and cheaper than BTC ... great! ... but what about my precious bitcoin??
-well part of the deal is proving you are you ... simple signature
-the other part of the deal is if you (and only you) send "UNO'r'us" 100kg of UNO then you will get 1 bitcoin in return
Is this so complex?
Yes. Still not a perfectly pegged product because a 3rd party will not honor the value.
So with some blockchain tech tracking "UNO'r'us" would pay anyone 1 bitcoin for the original 100kg UN.
Is this practical?
No. But very possible that "UNO'r'us" could write a specialized wallet client. It streamlines a chain within a chain to make it user friendly. "UNO'r'us" sets a daily peg rate so it is not fixed and can adjust to the approximate freemarket.
And in reality?
People want simple. And a less cartel like version of the The Lightning Network is already in use. Any exchange and online wallet company can move value off chain, and it is just a matter of public adoption and inter-exchange co-op. But that is still just trusting someone else with your bitcoin/privkey.
Another version of "UNO'r'us" ...
Very easy, Very practical. You send 1 bitcoin "UNO'r'us" and they send you say 80% that value in kg uno. So you have and hold a digital asset, i think that is called collateral? Now "UNO'r'us" runs a niffy online wallet service an you have 1 bitcoin of 'credit' and can send just as fast as the internet carries bits and you would pay "BoB's Bacon Shop" not some confusing bitcoin address. If "UNO'r'us" goes BigVern on you then you have their UNOs to sell and get back some/all/more of your bitcoin (freemarket). If you decide to screw "UNO'r'us" well they can sell your BTC and buy more UNOs. If both are good and trustworthy the deal can be reversed by just sending the coins back.
TLDR;
i am ranting about "sidechains" jargon. UNO ought just claim to be a sidechain of BTC. Because ETH, LTC, NXT, LISK, and all the other majors are going to use the term "sidechains" as part of their ecosystem.

Greg Maxwell: Lightning Network Better Than Sidechains for Scaling Bitcoin
Garzik : No.
https://bitcoinmagazine.com/articles/greg-maxwell-lightning-network-better-than-sidechains-for-scaling-bitcoin-1461077424“Our greatest motivation for the sidechain concept in Bitcoin was being able to better satisfy mutually exclusive objectives for the system. However, sidechains by themselves do not fundamentally change the scaling limitations of a global broadcast system, though they should provide security partitioning if an experimental chain should fail.”
Tuur Demeester: Veteran Dev. John Ratcliff on scalability: "Since LN is merely a mechanism for exchanging signed contracts, this means you can exchange contracts across multiple sidechains. Sidechains + LN to hyperlink them together is the killer scaling combination!"
