(2) (BEAM) A blockchain that uses the Mimblewimble protocol. Launched in 2017, BEAM allows users to control how much of their data they wish to share with the general public. BEAM employs the Equihash proof-of-work (PoW) algorithm that requires a lot of memory to compute but takes much less energy than traditional PoW chains such as Bitcoin. See
