With the release
of sidechains in Q4 2017, software developers that aim to develop on the Stratis blockchain will be able to develop applications that focus strictly on identity management for businesses.
In a recent interview with Bitcoin Magazine, Blockstream CTO Greg Maxwell shared his views
on sidechains as a scalability solution and why the Lightning Network will be a better option over the long term.
The most recent work in regard to a two - way peg mechanism
for sidechains comes in the form of a paper by RSK Labs (the company behind Rootstock) co-founder and Chief Scientist Sergio Lerner.
According to Blockstream, the code will allow community developers to experiment
with sidechain functionality, with initial features allowing users to transact and issue digital assets.
In theory, smaller transactions happen
in sidechains instead of on the main Bitcoin blockchain.
Masters expects the market to regain confidence
as sidechain companies develop usable technologies in the next nine to 18 months.
Bitcoin sidechain project RSK and even CryptoKitties are examples of projects that are centralized today, but their developers hope, with technological progress, they'll be able to decentralize over time.
This means you can create your own
sidechain projects using the Stratis» algorithm without being worried about its safety;
As open - source, protocol - level technology, developers can
use Sidechain Elements to extend the functionality of Bitcoin and explore new applications of the Blockchain.
With the release of
Sidechain Elements, Blockstream is moving this effort into the community.»
Tokens are transferred back and forth with ease, and private
sidechains allows for separate coins along with sequestered activities that won't necessarily affect the main chain.
With today's publication of Strong Federations: An Interoperable Blockchain Solution to Centralized Third Party Risks, we share the improvements we have made to the federated peg that was briefly discussed in the original
sidechains paper.
It's also a boon for businesses that need the extra security provided
by sidechains but don't want to build a custom blockchain from scratch.
Liquid is based on the Strong Federation
Sidechain concept where a group of «functionaries» produce blocks for the network.
In October 2015, the company launched its
own sidechain Liquid, which extends blockchain functionality and allows users rapid transfer and settlement in a separate high - volume and low - fee secure cryptographic system.
In a recent message to the Bitcoin development mailing list, Sztorc attempted to jump - start the conversation on a potential BIP (Bitcoin Improvement Proposal) to enable two - way
pegged sidechains on the Bitcoin network.
ETC devs are tackling this issue
via sidechain as opposed to keeping things «on chain» with bigger blocks (like Bitcoin Cash).
Three years later, it appears that drivechains, which are a specific way of
implementing sidechains, will be the way in which extensions for Bitcoin are rolled out.
That sort of setup would allow transfers
between sidechains to take place instantaneously.
Andrew Poelstra, a mathematician for Blockstream, said that the paper constitutes «a pile of improvements» over other systems given the company's experimentation with new bitcoin features such as SegWit and confidential transactions, which shield transaction information, on
testing sidechains.
Scalability is more straightforward, as
adding sidechains doesn't dramatically increase main chain activity.
Blockstream has released a whitepaper detailing the Strong Federations system, the foundation for the
Liquid sidechain project to improve privacy, costs, speed of value transfers and settlement among exchanges and brokerages.
While other
sidechain proposals seem to be running into hurdles, Drivechain is shifting into gear.
From sidechains to massive retail adoption, Bitcoin and others are making the kind of forward progress necessary for wide adoption (slow and steady wins the race).
According to Garzik,
while sidechains have a number of advantageous features, just like the Lightning Network they are «immature, unknown technologies» that have not yet seen the light of day.
He noted the launch of Liquid, a
new sidechain developed by industry startup Blockstream as proof that the bitcoin blockchain is versatile enough to meet the demands of institutions that want to develop private blockchain networks, while still gaining access to the security and network effect of the bitcoin blockchain.
The project's backers say its so - called «strong federations» could allow financial institutions to pin certain types of
private sidechains to the bitcoin blockchain, in part to take advantage of the network's security and the control that it gives to users.
It is a platform for distributed smart contracts, much like Ethereum, but the fact that it's a bitcoin
sidechain means that it will use the bitcoin currency by default.
If the blocks stay small, the devs need to work on solutions that move transactions completely out of the main chain and
into sidechains which have their own context in which to execute transactions.
In addition, any transactions that occur on a Stratis
sidechain don't run the risk of being «bloated.»
As of the time of this writing,
Stratis sidechains are set to to be released in alpha phase in Q1 2018.
Decentralised application and
sidechain platform Lisk has completed initial coin offering (ICO).
Developers and users of the main network can create
sidechains which allow the main blockchain to remain unburdened.
Blockstream will seek to
provide Sidechain Elements as a base for the nearly 30 blockchain innovation initiatives that have been announced by major financial institutions in the past few months.
Humaniq has solved the scaling challenges of ERC20 projects by preserving the benefits of the Ethereum main - net and creating a «unique combination of
sidechain solutions in individual African countries such as Uganda, Senegal, Zimbabwe, Tanzania, and Rwanda.»
As recently as this month, Todd has said, «[Merge -
mined sidechains] are a broken idea that fundamentally means miners have the ability to steal coins, and makes the scaling problem a lot worse.»
Truthcoin, a Bitcoin
sidechain designed by Yale Department of Economics Researcher Paul Sztorc, is described as a «peer - to - peer oracle system and prediction marketplace.»
«We further hope that this inspires others to build on these and other future improvements to the Bitcoin codebase and encourages others to take advantage of our work in both the original
sidechain white paper and the implementation in Elements Project open source releases.
Lisk supports
also sidechains, that will make it free from scaling problems.
Unlike other mainstream cryptocurrencies, Lisk markets itself as the first «modular cryptocurrency
utilizing sidechains.»
Bitcoin startup Blockstream's
first sidechain, dubbed Liquid, is launching in beta on the live bitcoin network.
Since
sidechains need to work both ways in order to be functional, and Bitcoin can not provide a withdraw function for the secondary asset to be converted back into Bitcoin (yet), a semi-decentralized alternative for a 2 - way peg was found: Federated pegs.
The paper builds on work by Blockstream on the
original sidechains concept and a more - recent proposal, drivechains, from Sztorc.
