Sergio Demian Lerner, Chief of Innovation at the IOV Innovation Garden, recently created a new draft RSKIP titled Simple Parallelizable Semaphore. This RSKIP proposes adding a precompiled contract that provides a semaphore function. This function aims to replace the typical semaphores implemented as contract storage cells. You can find the text of the RSKIP for details here: [RSKIP336](https://ips.rsk.co/IPs/RSKIP336.html) ---

Thank you so much for being available to discuss with the community about this RSKIP. I have shared this with the open slack community, I hope we get some community members to study the RSKIP, and then get back with questions. šŸ™Œ
