BigchainDB and Beyond
- 1. BigchainDB and Beyond A blockchain application stack for the cloud Dimitri De Jonghe
- 2. About me... ● ● 2008 Master micro-electronics (KULeuven) ● 2013 PhD on applying machine learning to micro- electronics design (KULeuven) ● 2014 Machine learning startups (sydelity, scriptbook) ● >2014 ascribe.io - BigchainDB ○ ascribe.io - bitcoin blockchain for online licensing ○ BigchainDB - scalable blockchain database ○ IPDB Foundation - interplanetary database, public BigchainDB for commons ○ Interledger - the internet of blockchains Micro-electronics Machinelearning Blockchain My cat ● Dimitri De Jonghe (est. 1984) I like the potential of new technologies
