Overview – What is Blockchain?
![Page 4: blockchain beyond the hype - what we learned since 2017€¦ · Blockchain –Distributed Ledger "an open, distributed ledger that can record transactions between two parties efficiently](https://reader034.vdocument.in/reader034/viewer/2022042314/5f02c96a7e708231d4060185/html5/thumbnails/4.jpg)
Blockchain – Distributed Ledger
"an open, distributed ledger that can record transactions between two
parties efficiently and in a verifiable and permanent way.”Iansiti, Marco; Lakhani, Karim R. (January 2017)
”Decentralized, chronologically updated database with a network-based
consensus mechanism, used for the permanent securitization of
property rights.”Gabler Wirtschaftslexikon, translated from German
”The Slowest (and most Fascinating) Database in the World”Stefan Tilkov

Critical Appraisal
CON
▪ Blockchain only small part(<10%) of solution
▪Had to work aroundlimitations▪ Transaction queue
▪ Failover mechanism
▪ Admin user interface forcontrol and recovery
PRO
▪ Real-life use case
▪Goes live on Ethereum mainnet in May
▪ Potential for further usecases▪ capacity trading
▪ connect gas networkoperators from source to end consumer

What is a token?
Ethereum tokens can represent anything from a physical object like gold(Digix) to a native currency used to pay transaction fees (Golem).
The properties and functions of each token are entirely subject to itsintended use.
