  • Jak działa RenVM

    How RenVM Actually Works. What exactly is RenVM? And, how does it… | by Loong | Ren Project | Medium #📈Kryptowaluty #DeFi #RenVM #Bitcoin #Ethereum #ERC20
    • Versatile Decentralized, Trustless, and Permissionless Custodian
    • You give BTC to RenVM, it holds that BTC, and it mints that BTC as an ERC20 (a.k.a. renBTC) on Ethereum with 1:1 ratio to ensure your renBTC is always backed by the same amount of BTC.
    • 1. Fluid Value Exchange

      • RenVM stores the BTC in a network of decentralized nodes (called Darknodes).
      • Once RenVM receives BTC, it immediately mints a 1:1 ERC20 representation, that individuals and DeFi apps can use
      • it can be done hundreds of times per minute, at any time and in any amount without centralization, merchants, signatories, or friction, allowing the seamless movement of cross-chain digital assets (i.e. interoperability).
    • 2. Composability

Lenovo Legion Y530 Linux issues and solutions for wifi and touchpad mostly (Debian & Ubuntu)

Intel i7-8750H nVidia GTX 1050 Ti

Summary of my findings (Please comment if you can get further than me) :

edit: 06/2019 guys in the comments have found workarounds and new solutions !

Most importantly : Lenovo refuses to provide any kind of support for their product on Linux, even though the computer is sold without an OS
