The genesis

Blockchain Solutions was created in January 2016 in Paris. It is one of the first blockchain consulting firms of France. Its deep roots come from the Parisian Bitcoin community where the two current partners Pierre Porthaux and Isabelle Bonnet met.


Isabelle Bonnet


Isabelle discovered blockchain in 2017 launching her own trading algorithmic strategy and became in parallel a renowned expert of the topic for the luxury industry advising the Kering group and the Pinault family.

Graduated with a Master of Mathematics of Finance from Columbia University in New York and from the prestigious French engineering school Centrale, after several experiences in banks including one as a quant, she has led a successful career in strategy consulting advising PE and VC funds along with executive committees of mid to large caps.

Pierre Porthaux


Pierre discovered blockchain in 2011 and has been one of the first experts of the topic in France. He now holds a distinctive technical expertise and experience of both the crypto markets and blockchain based technical solutions.

Graduated with an engineering degree in computer science from ISEP and a business degree from the prestigious French business school ESSEC, after more than 10 years of career as an equity derivatives trader, Pierre has also successfully developed one of the first quantitative trading platform for crypto currencies with his venture Emergence Lab.


Blockchain Solutions is also a network of experts, our company is deeply connected with the blockchain ecosystem both in France (e.g. member of LabChain initiative from CDC) and internationnally (e.g. with Blockstream).
