Since Bitcoin and the blockchain were proposed in 2008, distributed ledger technologies and cryptocurrencies have spanned several areas of research. One of the biggest challenges of the field is how to scale the distributed system to support a higher transaction throughput, keeping a safe, distributed, and permissionless network. This work builds on top of the current blockchain and directed acyclic graph distributed ledger technologies literature and proposes a simple, fast and predictable algorithm to reach network consensus. It builds a model to formalize consensus on a DAG DLT and performs experiments to validate the feasibility of the proposed algorithm.
