ZELLULAR SEQUENCER

Replicating centralised services across multiple nodes creates a decentralised
system that remains robust, even if some nodes fail or act maliciously—this is
the essence of Byzantine Fault Tolerance.

The first phase in decentralizing a centralized service using this approach is
to replace the conventional username/password login with signature-based
authentication at every place where users send their requests to enable each
node to independently verify those requests.

In the second phase, ensuring that all replicated nodes maintain the same data
or state is crucial. This requires all nodes to receive and process user-signed
requests in the exact same order. If nodes process updates in different orders,
they can become out of sync. The Zellular Sequencer addresses this challenge by
making sure that every node in the network processes every request in the same
sequence.

In Zellular Sequencer, one of the network nodes, the Sequencer, takes the leader
role for sequencing tasks. User-signed requests received by a node are applied
to the database only after being sent to the leader and received back along with
other nodes’ requests in a consistent order.

If the Sequencer malfunctions—by going offline, censoring requests, or sending
inconsistent orders—other nodes can challenge its actions. Should enough nodes
agree, the Sequencer’s role will seamlessly transfer to a new leader. This
mechanism makes the Zellular Sequencer a Byzantine Fault Tolerant (BFT) service,
facilitating sequencing without a single point of failure.

This project is under active development.
