Hyperledger Fabric is one of the most widely used private blockchains, but what is it used for, and how does it work? Niloo walks us through the uses of Hyperledger Fabric, what Chaincode is, and why Private Channels are used!

What is Hyperledger?
Let’s start with what Hyperledger is not: Not a company. Not a cryptocurrency. Not a blockchain. Hyperledger is rather something like a hub for open industrial blockchain development. On its website Hyperledger explains:
“Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration, hosted by The Linux Foundation, including leaders in finance, banking, Internet of Things, supply chains, manufacturing, and Technology.”
Hyperledger does not support Bitcoin or any other cryptocurrency. But the platform is thrilled by blockchain technology. Not since the Web itself, the website tells, “has a technology promised broader and more fundamental revolution than blockchain technology.” Blockchains has the potential to “build a new generation of transactional applications that establishes trust, accountability, and transparency at their core while streamlining business processes and legal constraints.”
So we have a lot of promises - and we have Hyperledger. With it, the Linux Foundation aims to create an environment in which communities of software developer and companies meet and coordinate to build blockchain frameworks. The Linux Foundation founded the platform in December 2015. In February 2016 it announced the first founding members, in March 2016 ten more members joined.
Today Hyperledger has an impressive list of more than 100 members. The list covers a wide scope of well know industry leaders. It includes mobility tech giants like Airbus and Daimler, IT-companies like IBM, Fujitsu, SAP, Huawei, Nokia, Intel and Samsung, financial institutions like Deutsche Börse, American Express, J.P. Morgan, BBVA, BNP Paribas and Well Fargo, as well as Blockchain startups like Blockstream, Netki, Lykke, Factom, bloq and Consensys. A lot of the world’s largest companies in Tech and Finance meet at Hyperledger with some of the hottest blockchain startups.

Something like the executive government of Hyperledger is the committee of leaders. It consists of more than 10 executives, most with decades of experience in Open Source and tight connections to several industries. You’ll find leaders of the Apache Foundation and the W3C Consortium as well as engineers from IBM and more. Some of Hyperledgers’s members, like Richard Brown and Tamas Blumer, already worked with Blockchain for years. For its members, Hyperledger does not only provide technical knowledge and software frameworks but also various contacts to industries and developers.
Relatively early in the history of Hyperledger, the project had to make an important decision. Executive Director Brian Behlendorf was asked if there will be an “Hyperledger Coin”, a monetary unit running on the Hyperledger blockchains. Behlendorf answered that the Hyperledger Project itself will never build its own cryptocurrency. - Věda a technologie
Understanding Consensus Protocol and how they operate via nodes ties it all in. Also, knowing what makes a ledger different from your typical database helps as well. Once you get this, smooth sailing.
Amazing Explanation . Thank you so much !🔥
Very well explained! Thank you
This is very interesting, thank you!
Very well explained! to the point
You're awesome! very thorough!!!!!
Someone knows anything about the Metacoin of hyperledger? Where I can find some information about this?
It is obviously helpful to me . Thanks madam.
This is actually a very good video!
Awesome one.. Please do more videos on the architecture of fabric, transaction pruning and all.
Thanks Nandu! We have tons of Hyperledger tutorials and courses over at Blockgeeks, check them out! :)
@@BlockGeeks hello, does this have a coin? Where can it be buy?
Good stuff, well done
very nice intro indeed. thanks!
Glad you liked it Raghuvira! We have a more advanced Hyperledger course launching soon too! :)
Noob questions here. Who determines the access rights within these groups, especially if the groups run as a decentralized autonomous organization? Or does this type of blockchain not allow individual anonymity? How are the assets verified on the blockchain? How does it for example- prevent one company from scamming another company in a transaction with unverified assets? The peer node vs ordering node breakdown is also breaking my brain. What is the order in which things happen- is the transaction sent to both type of nodes at the same time?
Channel members can't scam one another as hyperledger relies on smart contracts, predefined on development stage.
Private peers validate blocks according to those contracts.
There's a logical error in your question about access rights determination on decentralized platform as every peer node connected to the private channel verifies transaction and this is what makes it decentralized.
And I think the order node operates on batching multiple transactions after they're being verified and processed by peer node.
Very crisp explanation 👍🏻
Crisp.
very well done
Who is operating the seemingly single (centralized) database that HLF includes in their architecture?
The database is overseen by however many nodes the network owners decide on. So let's say seven banks wanted to run a Hyperledger system between them-- each bank would likely own a few nodes that would relay, store, and verify information.
Hyperledger itself is just software. The team behind it doesn't really have any control over how you set up and operate your databases! That's entirely up to you! It can be as centralized or decentralized as it needs to be for the use case.
That shut her up lmao
Isn't this for the private blog chain quantum financial system for redeeming foreign currency? irs form 8912? If that is true why is the IRS headquarters located in Puerto Rico? And we can just move there with all our money. , live for 60 days and not paying any taxes?
Gracias Bro
Wait wait, it's a system that allows people to store and access information where certain people have different levels of authentication to access and edit that information? Holy shit that's a huge breakthru thank u so much
can u give me project topics in hyperledger sawtooth
Hyperledger is a great project but I would also point out AERGO - they also work with private blockchains for enterprises.
good point! I hold some AERGO in my portfolio :)
@@user-jk1uu5mj4j Wouldn’t the use of a private ledger impact your profit?

explained in simple words..
thanks a lot ...
It's much more better than edX course. more fluently and more understandable.
Thanks Ali! Hope you check out the full course on our site. :)
Which is the best institute to learn Hyperledger in Bangalore?
Hi, I am from Nagpur, I want to become an entrepreneur in the space, can we connect?
@@sohanwagwani8404, sure
Hey will u please suggest me some tools by them I can make a iot blockchain application using hyperledger as a framework. And also I want results. Plz help
i think your audio should be louder
Well its almost only Hyperledger Fabric. Title missleading.
Great video. Is your logo a 69?
U good
Audio is v low
Basically is a private blockchain, you need permission.
If this isn't the most comprehensive video ever, I'm disliking.
Akmon Ra did you dislike?
Probably disliked before watching
Very complicated for non tech.
A private blockchain is simply a none sense. It is like an aircraft used to drive on roads.
@valkyr11 use a database. It is much more efficient, scalable, and tested for decades
Dumbest comment ever😂😂😂
