The sentiment of CryptoNouveau event in Manhattan’s West Village during New York Blockchain Week was vibrant in the wake of the latest surge in crypto prices. It appears that many members of the blockchain community buckled down to build product and stayed under the radar while marketing was kept to a minimum. The results speak for themselves; the foundation of decentralized ledger technology has evolved in tremendous strides since last year’s event, and we cannot wait to see how the technology continues to mature in the coming months.

Below is a small sample of the companies that presented their incredible progress at CryptoNouveau. It was a pleasure to be among such a prestigious group of forward-thinking companies. We learned an enormous amount in our brief time there, and we hope this article will serve as a launchpad for you to engage with these companies during this exciting time.
