These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
This is a collection of web page captures from links added to, or changed on, Wikipedia pages. The idea is to bring a reliability to Wikipedia outlinks so that if the pages referenced by Wikipedia articles are changed, or go away, a reader can permanently find what was originally referred to.
IBM Blockchain based on Hyperledger Fabric from the Linux Foundation
Hyperledger, an open source collaborative effort to advance cross-industry blockchain technologies, is hosted by The Linux Foundation®. IBM provides blockchain solutions and services leveraging Hyperledger technologies, including Hyperledger Fabric and Hyperledger Composer.
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 chain, manufacturing and technology. These 130+ members and 8 ongoing projects, including Hyperledger Fabric and Hyperledger Composer, work in concert to create an open, standardized and enterprise-grade distributed ledger framework and code base.
Hyperledger Fabric is a business blockchain framework hosted by the Linux Foundation intended as a foundation for developing blockchain applications or solutions with a modular architecture. Hyperledger Fabric allows components such as consensus and membership services to be plug-and-play.
While leveraging open source best practices, Hyperledger Fabric enables confidentiality and scalability in business environments.
Hyperledger Fabric establishes trust, transparency and accountability
Provides collectively defined membership and access rights within your business network
Gives businesses the flexibility and security to make transactions visible to select parties with the correct encryption keys
Does not require mining and expensive computations to assure transactions
Leverage the embedded logic in smart contracts to automate business processes across your network
