The COTI Cluster explained

A live DAG simulation with Eli Hallufgil COTI’s technology team leader.


The Cluster, COTI’s distributed ledger, is based on a directed acyclic graph (DAG) data structure. The COTI simulation is the mathematical model of The Cluster using COTI’s base protocol.

The flow of new transactions has been modeled using the Poisson process. Each new transaction utilises the Source Selection Algorithm to select two sources, or points that have no inbound transactions in the DAG. It then validates those sources and becomes a source itself.

To reach transaction consensus, we need to find the heaviest cumulative Trust Score chain , or the Trustchain as we call it. If the cumulative Trust Score of the Trustchain has surpassed a predetermined threshold, then the transaction will have reached Trustchain consensus and can be confirmed.

Change simulation parameters in the dropdown menus.

The simulation parameters are as follows:

λis the number of incoming transactions per second.
Δtis the amount of time (in seconds) to run the attachment algorithm and do proof-of-work.
ρis the size of the trust neighbourhood to which a transaction can attach. This is expressed as a
fraction of the total number of sources.
The number of transactions is taken to be 3000.
The number of genesis transactions is taken to be 20.
The cumulative trust required for a transaction to be confirmed is 300.

We believe that decentralization is the future and that the Trustchain is the next generation blockchain 3.0 solution, which will bring the world one step closer to achieving mass adoption of cryptocurrencies.
