- 3. 1. Blockchain - terms 3 Blockchain - system of nodes to exchange data/transactions collected as block Node - blockchain participant (full nodes vs thin or light nodes) Miner - full node which validates transactions (the engines of the blockchain) Wallet - light node/software client of a distributed ledger/blockchain Transaction - data collected as blocks (the fuel of the blockchain) Difficulty - indicator how easily can a data block mined Ledger - distributed or central data store (synonym for blockchain) https://blockchain.wasistdas.org/
- 4. 1 - Blockchain - Ziele vs. Erwartungen/Träume Ziele: Blockchain fits - Privacy: Datensicherheit durch RSA - Scale: Skalierbar durch Dezentralität - Identity: Identifizierbar durch Token Erwartungen/Träume - Grenzenlos :D Beispiel:https://anders.com/blockchain/blockchain.html 4 https://blockchain.wasistdas.org/
