IBM, Walmart to pilot blockchain network for prescription drug traceability Cannabis on a blockchain: Security Matters files patent for plant tracking Blockchain ID checks: How this startup is now verifying identities online Editorial standards
While IBM is using blockchain to improve transparency in supply chains for internal stakeholders, start-ups such asProvenanceandEverledgerare using blockchain to provide supply chain transparency directly to consumers. Everledger, for example, traces the origin of diamonds from provenance and verifies au...
blockchain technology is utilized to secure a variety of digital transactions. A concept that was originally designed to help make transfers of digital currencies is now being applied to a number of different online transactions. The purpose of blockchain is to create a free, open, fair, equal...

it, where each block refers to the one below. In the ethereum public blockchain, the genesis block was created on July 20, 2015. To build our own blockchain, we need to create our own genesis block. Use the following command to init our private blockchain with the given genesis block...
Closed blockchain systems would make it hard for smaller suppliers to benefit from the technology potentially resulting in giving more power to large firms instead of improving working conditions. Also, in developing economies, manysmall-scale farmersand suppliers do not have the technological infrastruc...
on the IBM Blockchain Platform V2 Beta, and enable a coffee retailer to ensure the customer that their coffee is organic and fair-trade. The code pattern can be useful to developers that are looking into learning more about creating applications that integrate supply chains with Hyperledger ...
This research uses sensemaking theory to explore how emerging blockchain technology may transform supply chains. We investigate three research questions (RQs): What are blockchain technology's perceived benefits to supply chains, where are disruptions mostly likely to occur and what are the potential ...
Blockchains can be used to make data in any industry immutable—meaning it cannot be altered. Since a block can’t be changed, the only trust needed is at the point where a user or program enters data. This reduces the need for trusted third parties, such as auditors or other humans...
to the chain at the same time another valid block is. These two blocks are used to create more blocks, causing two chains to emerge. Eventually, one of the chains will have more proof, and the other chain will be discarded. The blocks of the shorter discarded chain are the orphan ...
