FAQs
Please follow the instructions here to make a Linux Foundation account.. If you've done that and are still running into problems, send us an email at community-architects@lfdecentralizedtrust.org.
If you have any questions regarding the different projects, you are welcome to join the project channels on the LFDT Discord or attend any of the relevant public community calls and ask questions there.
The Linux Foundation does have training courses and certification exams for some of our projects. Project maintainers also have created workshops and tutorials that you might find helpful.
There are two ways to host your code with us:
-
Start a lab - https://lf-decentralized-trust-labs.github.io/ details the requirements and process to propose a lab. This is the quickest and easiest way to get started.
-
Start a project - The project lifecycle details the process that a project must go through in order to be accepted into incubation. The advantage of starting a project instead of a lab is that LFDT staff does more to support projects.
LF Decentralized Trust is an open source collaborative effort that is hosted by The Linux Foundation. There are a number of different projects that exist within the community. All source code hosted by LFDT is licensed under the Apache 2.0 license, unless an appropriate exception has been obtained. A summary of the license can be found at https://tldrlegal.com/license/apache-license-2.0-(apache-2.0); however, we recommend consulting a legal expert who can help you understand the license of any open source code you want to use, including any dependencies that the source code has.
LF Decentralized Trust is an open source collaborative effort that is hosted by The Linux Foundation. All projects we host are open source, which means that you can download and use the software free of charge.
When you deploy a blockchain network using one of our distributed ledger frameworks (e.g., Hyperledger Fabric), you will need to pay for the hardware necessary to run the underlying blockchain network, as well as the application code that you write to access the blockchain network. This hardware could be located on-premise or in the cloud. This would be the same model that you would have with any other type of software that you might need to install to run your use case.
All projects that we host are open source, which means that you can download and use the software free of charge without joining LF Decentralized Trust. Some organizations choose to become members though because we offer a number of membership benefits that you may also be interested in.
Which Hyperledger project will allow me to create a blockchain network with smart contracts? Which consensus mechanism is being used?
We have several different DLTs (Distributed Ledger Technologies) that you can use to set up your own blockchain network.
All of the frameworks, except Hyperledger Indy, are general purpose -- meaning that you can store whatever type of asset you want. Hyperledger Indy is a framework that is focused on decentralized identity. Besides checking out the project pages for the different DLTs, you can also have a look at the Project Matrix which has more detail about the different projects that we host.
Check out the Use Case Tracker for a list of a number of solutions that are using LFDT frameworks and tools.
No. None of the DLT frameworks we host utilize proof of work (PoW) for consensus. Because the frameworks are designed for permissioned networks where the actors are known, they can use consensus mechanisms that are crash fault tolerant or byzantine fault tolerant, which do not require the amount of compute power that PoW does.
The different frameworks we host are designed for organizations to take and build solutions with and you can use the frameworks to set up your own networks. As such, there is no public network.
