Latest applications:
(May 2020) Notarization on Ethereum - Register for free your data on the Ethereum Blockchain

Latest researches:
(2019) Quorum: Ethereum for enterprise applications - Presentation for a GoBlockchain Webinar
(2019) Tokenization - Consulting on the subject

Objectives of this page:
- Implementation of a Blockchain applications 
- Sharing of some Blockchain knowledge: basic and advanced
- Personal knowledge growth (see this post)
- Connection with more passionate people about the Blockchain technology

What this page will have:
- An Ethereum ERC20 token (purpose: to exemplify the uses of a Blockchain token)
- Example of data hashing (SHA256)
- Proof-of-Worf verification
- Merkle Tree example: transaction tampering verification
- Simulation of a chain of blocks
- Encryption application - first one: Caesar Cipher
- Application for storing data on the Blockchain (use case: notarization)
- Search of data stored on a blockchain
- An ICO example: a simple example (article soon)

Blockchain experiments:
- Raising funds with Bitcoin to aid the homeless on winter: Steemit post
- Storing data on the Blockchain (Ethereum Rinkeby network): here
- Football matches line-up on the Blockchain: here (Dapp soon)
