Fusus Data Structure & Proof of Utility (PoU) Demos Available Online

  • FUSUS is Jura’s novel data structure that is a multiple inheritance of blockchain, block lattice, and directed acyclic graph (DAG) technology. The FUSUS is a flexible, practical, and scalable data structure that provides us with the ability to achieve scalability, fast transactions, lightweight, and instant confirmation all at once.
  • The FUSUS is essentially a DAG-lattice. This essentially means that the transaction histories of accounts form the lattice, and the history of each account is constructed by the DAG. In simple words, when the traffic volume is low, the DAG is effectively reduced to a blockchain structure, but when the traffic volume is high, the RTs form a DAG, and every ST plays the role of a new genesis block.

  • Proof of Utility (PoU) Consensus Mechanism: Think of PoU as a sort of credit score: a single value that describes the trustworthiness of an account by taking into account a range of different variables, and in a consensus mechanism, votes from an entity with a higher PoU would be weighted more than someone with a lower PoU. Our model thus far takes four different variables into account: the stake size, the age of the account, the average staking time, and the last staking time. Each of these variables is assigned a dynamically changing weight that will adjust itself in accordance to the system demographics.
  • In that sense, PoU is akin to a multidimensional, dynamic PoS, except one cannot game the system simply by controlling the majority of the stakes. Although we know which variables go into making a higher PoU, we don’t know what the weights of each one are, and furthermore, the weights will change over time. This effectively guarantees that no one will remain king of the hill.
