- 79. So which app is good with Blockchain?
- 80. • Similar thing can be implemented on (traditional) centralized technology (Client-server Application) • There is at least trustful party which can provide the centralized platform • No party can fully trust each other • Security and Immutability • Perfect transparency • Replacement of old tech that require open standard. Blockchain overkill if… What does Blockchain fit? Blockchain Application Summary
- 82. Traditional Money Remittance 1. Alex goes to his local hawala agent and gives him some cash and a password, which he and Beth share. 2. The agent telephones Beth's local agent and tells him to release funds to someone who can provide the password. 3. Beth walks in to her agent, says the password, and receives cash. Commissions can be taken from either or both agents. • Alex has to trust that his agent will do the right thing, as he is handing over cash. • Beth has to trust that her agent will do the right thing, as she is expecting to receive cash. • The agents need to trust each other over the repayment of the debt (IOUs).
