    Study Notes

    Blockchain and DLT Research Group at UZH: Understanding the Principles and Functioning of Blockchains

    • Law of proportionate growth: In socioeconomic systems, the growth of an agent is proportional to its size.
    • Blockchains are a paradigm of complex socio-techno-economic systems, created to address the increasing centralization accelerated by digitalization.
    • Trust in few entities introduces single-point of failure and access to identities, leading to centralization in the creation of money.
    • Blockchains aim to create a decentralized, transparent yet anonymous, open monetary system where pre-existing trust among participants is not necessary.
    • The functioning of these systems is based on algorithmic protocols and a set of economic incentives.
    • Key principles behind blockchains include a distributed peer-to-peer network and a distributed append-only database for data storage.
    • Transactions are verified in a decentralized manner through a public registry replicated in all nodes of the peer-to-peer network.
    • Transactions are packed into blocks before verification to allow for simpler agreement («consensus») and introduce a natural order.
    • Each block is created by someone and contains a set of verified transactions at the same time.
    • The relationship between design principles and outcome received opposing views from anarcho-capitalist communities in the aftermath of the 2008 crisis.
    • Blockchains were created to enable exchange of value of digital assets without trusted central entities and open participation in the process of money supply.
    • The ideal behind blockchains is to eliminate the need for pre-existing trust among participants and allow trust to emerge because of the system's operation.
