... 4 mathematical proofs. Nodes communicate, reach consensus (using different systems, depending on the blockchain)
From page 17...
... 5  Privacy: Pseudo-anonymity may not be protective enough, especially in an enterprise or consortium blockchain that is controlled by one or a limited number of parties;  Integration and interoperability: Integrating blockchain into existing legacy systems and between different blockchain ecosystems could be challenging;  Governance models: In a consortium blockchain, parties need new governance models; and  Regulation: The regulatory framework for blockchain is still uncertain. Adams noted key questions for determining whether it is appropriate to consider blockchain for a particular application, including whether  A database is needed to record a transaction or state changes (if so, blockchain may be appropriate)

... 7 vouchers, for loyalty program execution, for exchange of vouchers for goods and services, and other applications. Additionally, blockchain can be used to distribute data and crowdsource improvements to AI/machine learning models, improve process optimization and tracking, and facilitate payments.

... 8 Petracek summarized the typical blockchain implementation journey from use case study through proof of concept to deployment. Petracek noted that deployment can be complicated and can involve multiple parties.
From page 21...
... 9 important as technology advances. Awareness of blockchain is built through experimentation.
From page 22...
... 10 Algorithms vary across blockchain networks, and certain algorithms are appropriate for certain use cases. For example, proof-of-work algorithms are primarily used for Bitcoin and Ethereum.
