Sobre blockchain, smart contracts, ethereum y otros temas


ICO  - Crowdsale Contracts


Casos de uso
  • Real State: cualquiera compra tokens y se realiza un emprendimiento inmobiliario.
  • Bitcoin: terminará siendo el Swift de los bancos.
  • Estonia: sociedad digital. X-Road, KSI, Guardtime, digital identities, e-residency, Crypto token “estcoin”.
    • The X-Road is the open-source backbone upon which the country’s entire digital infrastructure runs. First put into practice in 2001 (it’s been upgraded and altered many times since), X-Road is rooted in a blockchain called K.S.I., which was developed by Guardtime, one of the biggest blockchain companies in the world. K.S.I. is incidentally used by both NATO and the US Department of Defense.
    • “This is all really about the mindset. It’s about the culture. It’s about the human relations – it’s about what it enables us to do.”

    • BURRROW: Permissionable Smart contract machine (EVM)
    • Hyperledger Burrow is one of the Hyperledger projects hosted by The Linux Foundation. Hyperledger Burrow was originally contributed by Monax and co-sponsored by Intel. Hyperledger Burrow provides a modular blockchain client with a permissioned smart contract interpreter partially developed to the specification of the Ethereum Virtual Machine (EVM).
    • FABRIC: Permissioned with channel support
    • INDY: Descentralized identity
    • IROHA: Mobile application focus
    • SAWTOOTH: Permissioned & permissionless support; EVM transaction family
