1. 1. Smart Contract Maturity Model

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Jordy Jordanus Cornelius van Raalte; [2023]
   Nyckelord :smart contracts; maturity models; smart contract problems; blockchain; proof of work; proof of stake; smart contract implementation problems; smart contract use cases; smart contract challenges; smart contract opportunities; bitcoin; Ethereum; Hyperledger fabric; Codra; Ethereum smart contracts; smart contract platforms; maturity models and CMMI maturity model;

   Sammanfattning : A smart contract is a recently emerging technology which enables agreement to be automatable by computers and enforceable by legal enforcement or tamper-proof execution of code. A majority of smart contracts are run on the blockchain which enables smart contract transactions without a central authority. LÄS MER

3. 2. The effect of covid-19 announcement on sustainable investment portfolios : Observation of the flight-to-quality phenomenon

   Magister-uppsats, Jönköping University/Internationella Handelshögskolan

   Sammanfattning : Blockchain-based cryptocurrencies is a fairly new concept with a worldwide spread, and there is a massive amount of currencies. Several of them involve so-called currency mining, a feature of Proof-of-Work based blockchains. LÄS MER

5. 4. Consensus Algorithms in Blockchain : A survey to create decision trees for blockchain applications

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Xinlin Zhu; [2023]
   Nyckelord :Blockchain; Cryptocurrency; Consensus Algorithms; Proof of Work; Proof of Stake; Hybrid Consensus; Decision Tree; Blockchain; Kryptovaluta; Consensus Algoritms; Proof of Work; Proof of Stake; Hybrid Consensus; Decision Tree;

   Sammanfattning : Blockchain is a decentralized database that is distributed among a computer network. To enable a smooth decision making process without any authority, different blockchain applications use their own consensus algorithms. The problem is that for a new blockchain application, there is limited aid in deciding which algorithm it should implement. LÄS MER

7. 5. The Impact of Demand Patterns and Pathfinding Strategies on Payment Channel Networks

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Johanna Löv; [2023]
   Nyckelord :Payment Channel Network; Channel Imbalance; Pathfinding; Demand Pattern; Lightning Network;

   Sammanfattning : Payment Channel Networks (PCNs) provide a solution to the scalability problem in blockchain technology. They facilitate multiple-hop transactions via payment channels between peers, allowing for the execution of several transactions before updating each node’s balance on the blockchain. LÄS MER
