- blockchain at a minimum is DLT - decentralized ledger technology
- an immutable ledger provides a trusted ledger of transactions for all participants in the network
- like any technology, blockchain can add real value when applied correctly to the right use cases
- public blockchains
- Bitcoin and Ethereum are the 2 most popular public blockchains
- Ethereum offers smart contracts to provide common business logic controls on transactions
- Ethereum could also be implemented as a private blockchain when needed
- public blockchains allow anyone to participate
- public blockchains normally provide a degree of anonymity for participants but everyone can see all transactions
- public blockchains with a high number of commit nodes typically have poor performance
- permissioned blockchains
- permissioned blockchains are normally private and require participants to enroll through member services
- permissioned blockchains require read and write permissions to access the blockchain
- permissioned blockchains normally have identified participants
- participants are added through membership services
- transactions may be private between specific participants but macro demand is often public

He has just released a three-part series on blockchain that is excellent, and each is a quick read. #1 Blockchain is here - are you ready, #2 Blockchain isn't the end of trust, it is the future of trust, and #3 Your Blockchain close encounter of the first kind. Here is the first article, and I will let you find the next two on his site. Great work, Jim... https://lnkd.in/eJ8qGBE |
