Umareum Concensus
What is Consensus Mechanism?
Blockchain consensus refers to the process by which blockchain network nodes agree on the ledger's current state. In a blockchain network, every node has a copy of the ledger, and the nodes must validate any changes before they can be added to the chain.
Ultimately, the goal of any consensus algorithm is to ensure that the ledger is updated in a secure and trustworthy way without the need for a centralized authority to oversee the process.

1. BlockDAG mechanism
A significant drawback of a single chain topology is its capacity to handle only one block at a time. Now, what if the network could accommodate multiple blocks concurrently? This not only boosts transaction throughput but also reduces the inefficiency associated with a single chain topology, where the network discards all branches except one, resulting in wastage.
To illustrate a more inclusive approach, instead of constructing a linear chain, we opt for a graph-based structure. What may surprise many is that, while most people envision a blockchain as a straightforward linear chain, classic single chains like BTC and ETH are, in fact, composed of branches, resembling a tree rather than a linear chain. This tree-like structure falls under the category of a graph, to be more precise, a directed acyclic graph, commonly known as a DAG.
Now, "DAG" might sound rather sophisticated, but it's essentially a term used to describe the following characteristics:
Connectivity: Blocks (referred to more formally as vertices in mathematical terms) within this graph are interconnected.
Directionality: These connections (typically known as edges in mathematical contexts) possess directions; for instance, block A points to block B.
Cycle Absence: If you trace these directed connections starting from any block, you'll find that you cannot return to the same block, regardless of the path you take. In other words, this graph is devoid of cycles.
2. Proof-of-Work Consensus
Proof of Work (PoW) stands as one of the fundamental consensus algorithms within the blockchain ecosystem. In its core concept, PoW necessitates that participants, often referred to as miners, engage in solving intricate mathematical problems. This computational effort is the key element that defines PoW, hence its name.
However, the relevance of PoW extends beyond its role in validating transactions:
Enhanced Security: The considerable computational effort and resources required to solve PoW puzzles make it exceptionally costly for any malicious actor to manipulate the blockchain's historical records.
Equitable Participation: PoW ensures that engagement in the network and access to rewards remain accessible to anyone equipped with the computational capability for mining.
Promotion of Decentralization: PoW actively encourages a decentralized network by permitting any participant, regardless of their financial stake or identity, to actively contribute to the maintenance of the blockchain.
Reliability and Resilience: As numerous miners compete to solve PoW puzzles, the network becomes highly resilient to both faults and targeted attacks, ensuring its robustness.
Umareum Implemeting PoW
Umareum respects the foundational strengths of the traditional PoW mechanism while innovating with a distinct approach:
Highly Scalable PoW Consensus: In contrast to conventional PoW networks that often grapple with scalability issues, Umareum stands out by facilitating a throughput exceeding 10,000 transactions per second (TPS). This impressive scalability is achieved without compromising on security or decentralization.
Resource Optimization: Acknowledging the environmental considerations associated with PoW, Umareum incorporates algorithms that intelligently manage energy consumption while upholding the integrity of the consensus. This approach addresses environmental concerns while preserving the robustness of the network.
Rapid Finality: Umareum's PoW system is engineered for efficiency, boasting a swift block finality time of just 5 seconds. This quick finality demonstrates the network's optimized design, ensuring prompt confirmation of transactions without compromising security.
Future-Ready Architecture: Umareum is purposefully architected with adaptability in mind. The PoW mechanism is built to accommodate potential upgrades, ensuring that the network remains at the forefront of blockchain technology. This commitment to future-proofing guarantees that Umareum stays relevant and competitive in the ever-evolving blockchain landscape.
