Introducing POPR: A Rare-Object Registry on Ethereum

Special thanks to Nick Johnson of the Ethereum Foundation for early guidance and feedback. Introduction This post introduces an object provenance registry called POPR (Public Object Provenance Registry), on the Ethereum blockchain, as an extension of ENS (Ethereum Name Service). We will delve into how this system can be used to identify and certify rare … More Introducing POPR: A Rare-Object Registry on Ethereum

AI – An introduction to neural nets and deep learning (part 2)

Parameter swarm in neural nets. Part 1 gave us a broad overview of the founding ideas of deep learning. Whether it be MLPs, convolutional networks or even RNNs, every type of neural net suffers from the huge computational cost attached to its training. The number of parameters required to train a net increases quadratically with the … More AI – An introduction to neural nets and deep learning (part 2)

AI – An introduction to Neural nets and deep learning (part 1)

The Race for AI. Since 2011, leading tech firms among which Google, Facebook, Apple, IBM, Twitter, Microsoft, have acquired over 140 AI companies according to cbinsights.com. More than 40 of these acquisitions took place in 2016 alone, and huge amounts of money were spent: Google paid $600M for DeepMind, Twitter spent $150M for Magic Pony, … More AI – An introduction to Neural nets and deep learning (part 1)

Machine Learning & AI challenge on datascience.net – Team EY Lab Paris’ winning solution

In December 2016, EY launched a worldwide internal data science challenge on datascience.net – an online platform for machine learning and AI competitions. The goal is to train mathematical models to predict a target value, given some correlated variables (base features). The quality of the prediction is determined by a scoring function. Competitors are usually given two … More Machine Learning & AI challenge on datascience.net – Team EY Lab Paris’ winning solution

For a fistfull of Ethers – Setting-up a Mining Rig

The full power of the Ethereum public network comes from the high number of nodes running the blockchain and the hashing power securing it. Ethereum allows users to write and execute codes on the blockchain that are commonly called smart-contracts. The resilience and immutability of the smart-contracts come at the price of “real” ethers to … More For a fistfull of Ethers – Setting-up a Mining Rig

Going public but staying permissioned – Hands on EcRecover

When discussing blockchain technology for business you typically face a recurring dilemma. It is not about choosing between Bitcoin or Ethereum they are two households, both alike in dignity but rather about public versus private or permissioned blockchains. The efficiency of a blockchain application improves as the number of peers in the network and the diversity among … More Going public but staying permissioned – Hands on EcRecover

Forking to update – Diary of the last 3 months on Ethereum (Part 1)

Ethereum is a blockchain designed to act as a decentralized computing platform where every node of the Ethereum network executes upon request the codes written in the blockchain. Those codes are usually referred to as smart-contracts and written in specific domain languages like Solidity before being compiled in opcodes for the Ethereum Virtual Machine (EVM). … More Forking to update – Diary of the last 3 months on Ethereum (Part 1)
