Question: Which consensus algorithm / protocol is used in redbelly blockchain?

Redbelly blockchain is a novel distributed ledger technology that aims to achieve high scalability, security and performance. One of the key features of redbelly blockchain is its consensus algorithm, which is based on the concept of democratic Byzantine fault tolerance (DBFT).

DBFT is a protocol that allows a network of nodes to reach an agreement on the validity and order of transactions, even if some nodes are faulty or malicious. DBFT differs from other Byzantine fault tolerance protocols, such as PBFT or Tendermint, in that it does not require a fixed set of validators or a leader election process. Instead, DBFT allows any node to propose a block and any node to vote on it, as long as they have enough stake in the system.

The main advantage of DBFT is that it can achieve high throughput and low latency, as blocks can be proposed and confirmed in parallel by different subsets of nodes. Moreover, DBFT can tolerate up to half of the nodes being faulty or malicious, as long as the honest nodes have more than 50% of the total stake. This makes redbelly blockchain resilient to various attacks, such as Sybil attacks or censorship attacks.

In this blog post, we will explain how DBFT works in more detail and how it enables redbelly blockchain to achieve its goals. We will also compare DBFT with other consensus algorithms and discuss its strengths and limitations.
