Stochastic Block Model: A statistical model for generating random graphs wherein nodes are divided into groups, and edge probabilities depend on group membership. Community Detection: The process ...

A directed acyclic graph or DAG is a data modeling or ... validated when the previous one is completed. The DAG model eliminates these blocks, adding transactions directly to the blockchain.

model. Users are only allowed to have one transaction placement under their UTXO. There might be more than one miner who solves the hash function at the same time to acquire the right of block ...

In a second step, weights are allocated to a sampled adjacency matrix via an exponential random graph model (ERGM) that fulfills the desired row, column and block weights. This model is analytically ...
