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.
Hey there! I am Sudhir Khatwani, an IT bank professional turned into a cryptocurrency and blockchain proponent from Pune, India. Cryptocurrencies and blockchain will change human life in inconceivable ways and I am here to empower people to understand this new ecosystem so that they can use it for their benefit. You will find me reading about cryptonomics and eating if I am not doing anything else.
If you want a deeper look at Proof of Stake check out our detailed POS post. In short, while Proof of Work is an effective mechanism to secure the blockchain and provides a trustless consensus paradigm, it’s extremely energy intensive because of all the computing power required to solve hash problems. Also, while it was meant to be decentralized, it’s actually becoming more centralized as miners consolidate and massive mining setups eat up larger shares of winning blocks.
Instead, what if the game was played in its own “channel”? Each time a player made a move, the state of the game is signed by each player. After an epic battle where the Protoss player takes out the remaining Zerg forces and forces a gg, the final state of the game (Protoss wins) is sent to a smart contract on the main chain. This neutral smart contract, known as a Judge, waits a while to see if the Zerg player disputes the outcome. If the Zerg player doesn’t, the Protoss player is paid the 1 ETH.
The good thing about sidechains is that they are independent of their main chain. Sidechains take care of their own security. Problems occurring on the sidechain can, therefore, be controlled without affecting the main chain. Likewise, a security problem on the main chain does not affect the sidechain although the value of the peg is greatly reduced.
A big thanks to Diego Salvador for helping me write this episode. Him and the rest of the team over at Rootstock are doing fantastic work with cryptocurrency and Sidechains. We wish them all the best. I'll be sure to leave a link to their website in the top of the description so you can go check it out and learn more if you wish. And as always, be sure to subscribe and I will see you next time.
Since extension blocks can be implemented via soft forks, the features of the extension blocks are essentially opt-in for users. Even in the case of extension blocks with a larger block size limit, users are not forced to upgrade and validate or propagate blocks that are much larger in size. Those who wish to enjoy the level of decentralization offered by 1MB blocks can continue to do so, while those who would like to experiment with much larger block size limits can do so on an opt-in basis.
A public blockchain has absolutely no access restrictions. Anyone with an internet connection can send transactions[disambiguation needed] to it as well as become a validator (i.e., participate in the execution of a consensus protocol).[self-published source?] Usually, such networks offer economic incentives for those who secure them and utilize some type of a Proof of Stake or Proof of Work algorithm.
In general, so far there has been little emphasis on the distinction between consortium blockchains and fully private blockchains, although it is important: the former provides a hybrid between the “low-trust” provided by public blockchains and the “single highly-trusted entity” model of private blockchains, whereas the latter can be more accurately described as a traditional centralized system with a degree of cryptographic auditability attached. However, to some degree there is good reason for the focus on consortium over private: the fundamental value of blockchains in a fully private context, aside from the replicated state machine functionality, is cryptographic authentication, and there is no reason to believe that the optimal format of such authentication provision should consist of a series of hash-linked data packets containing Merkle tree roots; generalized zero knowledge proof technology provides a much broader array of exciting possibilities about the kinds of cryptographic assurances that applications can provide their users. In general, I would even argue that generalized zero-knowledge-proofs are, in the corporate financial world, greatly underhyped compared to private blockchains.
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.
It doesn’t matter if you’re moving $1bn or 0.01c across the Bitcoin network, you get the same security guarantees. And you pay for this in fees and time. What if you were prepared to trade safety for speed? Today, your only real option is to send the coins to a centralized wallet provider, whom you must trust not to lose or steal your coins. You can then do all the transactions you like on their books, with their other customers and you never need touch the Bitcoin blockchain. But now you lose all the benefits of a decentralized value-transfer network.
Side chains have two main advantages. Their first advantage they have is that they are permanent. You do not have to create a new sidechain every time you need to use one. Once a side chain is built, it is maintained and can be used by anyone doing a specified task off the main chain. The other advantage of sidechains is that they allow interaction between different cryptocurrencies. Developers get the opportunity to test software upgrades as well as beta coin releases before they are released on the main chain.
Sidechains, just like any other Blockchain, need their own miners to help protect them from nefarious actors and attacks which people would like to leverage against the network. However, since wealth isn't actually created on the Sidechain there is far less incentive for miners to actually work on it and help protect it. Because of this, transaction fees are the basic reward that is offered to miners. However, these often equate to mere pennies.
That might sound like a problem, but it isn’t because the box can only be opened infrequently (two or three times a year), and a super-majority of miners must leave a note on the box in advance. This note states exactly where the miners intend to transfer the money. The “correct” note is automatically generated by sidechain software, and is easy to check.
thank you for the clear explanation of this. so in essence, by locking bitcoins to a particular address we’ve created an asset (collateral). then on the other sidechain (marketplace) we get issued shares against the asset, which we can sell. anyone holding a share can then redeem it against the asset. I think that’s an analogy that finance types would get
Jump up ^ Redrup, Yolanda (29 June 2016). "ANZ backs private blockchain, but won't go public". Australia Financial Review. Archived from the original on 3 July 2016. Retrieved 7 July 2016. Blockchain networks can be either public or private. Public blockchains have many users and there are no controls over who can read, upload or delete the data and there are an unknown number of pseudonymous participants. In comparison, private blockchains also have multiple data sets, but there are controls in place over who can edit data and there are a known number of participants.
When blockchain technology was introduced to the public in 2008 (via Satoshi Nakamoto’s famous white paper), it would have been hard to predict that private or consortium blockchains would become popular. But recently, there’s been a lot of buzz about this in the digital currency community. Many companies are beginning to experiment with blockchain by implementing private and consortium chains, although some people are critical of this. This discussion not only centers on use cases and benefits, but whether non-public blockchains are an appropriate application of the protocol to begin with.

These kinds of blockchains are forks of the original implementations but deployed in a permissioned manner. Mainly hyped because the companies behind these chains want to onboard corporations in order to generate buzz around their their chain. It’s tolerable for proof of concepts or if they plan to move to public as soon as possible; otherwise they are just using the wrong set of tools for the job.
Let us call the current Bitcoin System Bitcoin 1.0 and the sidechain Bitcoin 2.0 So one would take one unit of Bitcoin 1.0 and send it to an unspendable address (e.g. 1111111111111111111114bRaS3) they’d also submit cryptographic proof of the transaction signed by the same private key that sent the transaction as a transaction into Bitcoin 2.0. The protocol of Bitcoin 2.0 would entitle the user to receive one unit of Bitcoin 2.0 This is called “One-way Pegging” as the value of one Bitcoin 2.0 is equal to one Bitcoin 1.0. This system is only one way and creates a wormhole by which Bitcoin 1.0 disappears as there is no way of getting it back.
Saying that, Interoperability has been the missing link in conquering the obstacles faced by both private and public blockchains by empowering them to interact and exchange values across platforms seamlessly. Developers use of the Gallactic blockchain technology, that allow for private and public blockchains within its eco-system, will drive the potential to combine both public and private blockchains with innovative new solutions, designed to accomplish cross-chain exchange and greater compatibility is the way forward for all parties and their concerns.
