Encrypted messaging, like Signal, is critical for preserving our digital privacy. Two important next steps for the space are (i) permissionless account creation and (ii) metadata privacy. Session and Simplex are two messaging apps pushing these directions forward. For this reason I've donated 128 ETH to each. Addresses available on their websites if you wish to follow on: https://getsession.org https://simplex.chat But also, actually download and use them! Neither of the two are perfect pieces of software, they have a way to go to get to truly optimal user experience and security. Strong metadata privacy requires decentralization, decentralization is hard, users expecting multi-device support makes everything harder. Sybil / DoS resistance, both in the message routing network and on the user side (without forcing phone number dependence) adds further difficulty. These problems need more eyes on them. I wish all teams working on these important problems best of luck.
