#Taproot, a huge change to the #Bitcoin protocol was activated today via soft fork - unnoticed by many (fun fact - the Bitcoin price did not significantly move up or down). It is a package of several changes:

  • It makes pay-to-pubkey-hashes and pay-to-script-hashes indistinguishable
  • In addition to ECDSA signatures, #Schnorr signatures will be available, which allow to aggregate signatures and thereby reduces the transaction size and increases privacy
  • Complex scripts will be compressed and abstracted with Merkle trees such that only the executed condition has to be provided.

Sounds confusing and gibberish? Yeah, so here is an example what Taproot enables: A multi-signature wallet, were coins can be spend with either 4-out-of-5 signatures or 3-out-of-6 after a time lock, will appear as a simple payment from one address to another (and thereby anonymize the participants) with lower fees than even a #SegWit transaction. That's powerful!

This week I said goodbye to d-fine, a great company I can highly recommend to anyone. Therefore I wanted to say thank you to the great colleagues I was honored to work with:

Daniil Gelfand for recommending d-fine to me 3 years ago.

Nils Pehoviak who introduced me to Blockchains and guided me on the first steps of my professional career.

Filipp Valovich whom I fully deserved called „Head of Cryptography“ and who joined me always on the hunt for sandwiches ;)

Daniela Merz-Lander - the greatest group leader you can imagine. Always ensuring a positive and productive work environment.

Dr. Timm von Puttkamer, a genius when it comes to technology, who knew the answer to every problem.

Vera Thümmler - thank you for sharing you passion for DDD with me.

Florian B. Bühler - who optimizes every pixel in the frontend until it’s perfect ;).

Matija Hustić - for our endless discussions on Java, JavaScript, Functional Programming ….

Alexander Glätzle - for the most pleasant cooperation.

Marc Henniges for his empowerment, being always approachable and open for suggestions - a great boss.

Dr. Marcus Hennig for teaching me the importance of clean code and encouraging me to pursue the best solution.

Dr. Matthias Hirtschulz for admitting me to d-fine’s Blockchain department.

A big thank you to Daniel Philipp, Yoann Trellu, Stephan Seidl, Karsten Leonhardt, Michelle Weber, Matthias Döring and Adrian Vetter as well as the whole d-fine back office team with whom my path crossed unfortunately only very shortly but who were nonetheless great colleagues and even more great people.

Thank you to all clients (who I unfortunately cannot disclose) for their trust in me and their supportive collaboration.

I am heading now for a new adventure and a new challenge joining Commerzbank AG’s DLT Lab and I am super excited to support them with my knowledge and expertise as well as helping with reorganization and focus on Blockchain, DLT and Digital Assets.
