Any transaction requires trust between parties. It’s been a long time banks have our de facto trust, but’s it’s much harder for smaller businesses to be trusted by their customers, especially when it comes to financial transactions. Blockchain allows us to create trustful transactions without the need for huge two-way audits beforehand.
When it was first created, blockchain was only used for the purpose of exchanging virtual goods existing on the chain itself. Soon were created the so-called smart contracts, whose state can be used to model any real-life use case. With their help, a general ledger of anything can be maintained.
In this talk, Grégoire will explain how, because today's transactions have to happen fast, using blockchain as a side medium to provide evidence of events can allow to let business logic be executed without waiting for a write, and still provide a high confidence that can be exposed to customers.
