What are the differences between Grin and Beam, implementations of the MimbleWimble protocol? Why has there usually been a trade-off between privacy and scalability? Grin is an open-source research project, with no pre-mine, a continuing issuance model, is developed by volunteers, and is written in Rust. Beam is more of a commercial product with a foundation that organizes funding and development, with a limited supply, and is written in C++.

  1. Maybe should be nice if someone with deep knowledge explain how nods are indentified in network if no adresses there. I still dont understand if grin isnt big secret joke. For me whole concept seems little funny if final transactions goes via mail.

  2. If the GRIN or Beam technology is better do you think they will replace Bitcoin? or You think Bitcoin or Monero will implement that approach? Gold isn't easy to copy by cryptocurrencies are easy to copy

  3. Andreas, could you make a video illustrating the roles of mining and nodes in securing the Bitcoin network. Highlight the differences. And go into detail on the potential scenarios that will occur when there are no or few coins left to mine? Also perhaps you could delve into what could occur if there were not a lot of on-chain transactions taking place. Would this lead to less incentive for minors to secure the network? Thank you so much. I and I think very much of the public is very uninformed these questions at hand.

  4. You are the man Andreas! Your videos are educational and so valuable! You are the perfect role model for me as a young information security specialist.
