The IOTA Foundation is actively working on IOTA 2.0, a blockchain that seeks to enhance the scalability, security, and decentralization of the IOTA blockchain. IOTA’s Senior Software Engineer, Dr. Bing-Yang Lin, recently shared some initial research results while testing the robustness of the IOTA 2.0 consensus mechanism. In this article, we will delve into IOTA’s challenges with the existing Tangle technology, the need for a more robust voting mechanism, and how IOTA 2.0 is the solution to these challenges.
The existing IOTA network leverages Tangle technology, which is a Directed Acyclic Graph (DAG). This structure allows users to play the role of both miners and creators of the transaction. The DAG structure has multiple benefits such as transaction efficiency, flexibility to adapt to higher throughput, small blocks that allow the validity of single transactions, and more. While traditional blockchain platforms face scalability issues, the IOTA network handles it with ease.
However, the Tangle technology has some challenges, including non-linearity or only partial ordering of transactions, practicability, and Sybil protection. The Sybil protection mechanism is offered through node weights, wherein each node carries weight as voting power, which is inherited through the issued blocks leading to a weighted Tangle. The approval weight is the number of nodes that agree that a transaction is valid. Finalization blocks are confirmed only once the approval weight reaches a confirmation threshold.
To overcome these challenges, IOTA 2.0 features a more robust voting mechanism that allows nodes to vote indirectly for a branch by attaching their transactions to it. Honest nodes attach their transactions to the first branch or the branch with the most approval weight among multiple branches. If the nodes notice that another branch has more approval weight than the branch they voted on, the nodes then attach the new transaction to the new branch, and their approval weight will be subtracted from the previous branch. This mechanism helps to ensure balance by ensuring that branches with higher approval weights get the transactions.
The IOTA 2.0 architecture seeks to provide scalability to the tune of 10,000 nodes and 1000 mps, making it suitable for sharding solutions. Unlike traditional blockchains, IOTA 2.0 seeks to be a permissionless blockchain that allows everyone to join the platform, creating a level playing field for small and big players with no minimum staking requirements.
IOTA 2.0 brings a significant transformational change to the existing IOTA ecosystem. With its robust voting mechanism, the blockchain attains better confirmation times of 1-2 seconds and is resistant to other bait-and-switch attacks, while delivering robust performance in a challenging environment. These developments provide a glimpse into the future of IOTA’s blockchain ecosystem, which seeks to be permissionless, scalable, secure, and offer a level playing field for small and big players alike.
In conclusion, IOTA 2.0’s robust voting mechanism enhances the blockchain’s performance by providing a more secure and decentralized environment. By enabling a permissionless blockchain with better scalability and faster confirmation times, IOTA 2.0 is an exciting development that could change the blockchain industry’s landscape. The IOTA Foundation’s continued work on IOTA 2.0 offers hope for the future of blockchain technology, providing new possibilities for a more secure and decentralized digital economy.
