Expectations for Paris Blockchain Week were relatively low considering the downbeat market conditions. However, Paris can always surprise you. Indeed, conference halls at the event were not nearly as empty or depressing as Consensus after the big crypto meltdown of 2018. People were present, and conversations were fruitful. (And yes, the croissants were, as always, delicious.)

In 2022, the conference was held symbolically in Palais Brongniart, a building known for hosting the historical Paris Stock Exchange until 1987. This time, organizers managed to outsoar themselves and held the event right under Louvre in the elegant “Carrousel du Louvre” conference halls.

Evening side events took place all around central Paris, overlapping and pushing some attendees to have three or even four dinners each night. Star speakers did not make any overly positive market predictions, but the conference vibe was definitely optimistic.

Is Paris the next best bet for crypto?

With regulators tightening their grip on crypto companies in the United States, Europe might be the next bet for crypto. While Paris is already home to prominent companies in the space — such as Ledger and The Sandbox — rumors are spreading that some big players will move their offices here or become more active in Paris.

Binance held its blockchain event in Paris last year. Circle just announced that it is seeking regulatory approvals in France and wants to establish a headquarters in Paris. Who knows? Coinbase could be next. Obviously, regulation will be a major factor in the future success of any European stablecoin or crypto service.

Need for crypto consortium

Another subject that flowed through many keynotes and discussions was the lack of industry collaboration. While it’s obvious to everyone now that crypto’s narrative is falling short, the question is: How can major industry players unite to stabilize the industry long-term and ensure its growth?

Some experts called for the industry to self-regulate as malicious players hurt everyone in the sector. Others stressed out a much-needed dialogue with regulators. If rules come from dusty offices without consultation with crypto industry players, the threat remains that those laws will become too complex, expensive or impossible to implement. Most experts agree and advocate for an industry-wide consortium. While initial industry collaborations to build discussions with the regulators have already started in the U.S. this year (with questionable results), much more effort is required.

Interoperability challenge

Experts across multiple panels raised interoperability concerns. Privately operated and centralized bridges have shown a vulnerability to hackers, and the lack of connectivity between networks hurts user experiences significantly and slows adoption.

Mobile carriers faced the same issues in their early days, but different smartphones and networks nonetheless manage to communicate flawlessly with each other today. Crypto users should similarly be able to switch in a safe and simple manner between applications and blockchains. From a technical standpoint, cross-application calls remain challenging even within a single blockchain, not to mention the same operation between two applications on different networks.

? Success favors those who enjoy what they do.

It was so fun and rewarding to chat with the brilliant, gregarious and delightful gigachads @yana_vc, @SamGab_G and Dominic Briggs at #ParisBlockchainWeek.

Existing solutions to traditional bridging (wrapping assets) are so-called “message passing” protocols that don’t move assets but enable calls between blockchains instead. Others are blockchain operating systems that use “state proofs” and reference them on other chains.

If this technical debate feels a bit overwhelming, the key takeaway is that many bright minds are seeking core technical solutions for interoperability. However, nailing it down in a decentralized way might take them a few more years.

This year’s Paris Blockchain Week presented curated content, carefully balanced between commercial talks, panels on deep tech and narrow topics, and entertaining keynotes — imagine Tim Draper singing a Bitcoin song on stage. (Yes, that happened.) Careful optimism prevailed; builders build and keep going!
