IOTA: New “Starfish” protocol creates 150,000 TPS and sets the scale in blockchain performance
- The IOTA Starfish Protocol reaches 150,000 TPS with a latency of less than a second and thus redesigned the scalability of DAGS.
- The rebased upgrade brings Iota the complete decentralization, staking premiums and web3-capable smart contracts in the 2nd quarter 25.
IOTA has released Starfish, a next generation consensus protocol that has redefined the scaling of DAG networks. The protocol was developed to overcome well-known performance and communication conflicts and introduces a new way for the cooperation of validators.
Starfish reaches a latency of less than a second and 150,000 transactions per second (TPS), even with a Byzantine attack. This enables Iota to strengthen the upcoming Rebased Mainnet and is at the top of the scalable layer 1 networks.
We’re excited to share our new whitepaper on #IOTA Starfish – our next-gen Byzantine Fault Tolerant consensus model for DAG-based protocols.

IOTA (IOTA) currently notes at $ 0.1560 and moves sideways. It is above the annual low of $ 0.1360, but below the high of 2023 at $ 0.4950. As CNF stated, the analysts observe the $ 0.20 brand as a resistance. A breakthrough could mean stronger recovery in the second quarter.
Solution of the DAG consensus dilemma
Most existing Dag-based Byzantine error tolerants (BFT) protocols are faced with a conflict of goals between efficiency and security. Certified Dags are secure however, require a high communication overhead. DAGS non -certified are faster, but are compromised in safety or bandwidth. Starfish, which was developed by the IOTA Foundation in cooperation with the University of Aix-Marseille, solves this problem.
The core is that Encoded Cordial Disseminationa method in which the validers share the full data of their blocks and encrypted fragments of the blocks of the others. By using REED solomone extinguishing coding and data availability certificates (DACS), the block data can only be reconstructed with a subset of the shared fragments used. This reduces the use of the bandwidness and maintains the fault tolerance. The white paper is available here and confirms that this model has a linear amortized communication complexity.
The IOTA Foundation says that Cordial dissemination reflects the design principle of the protocol: If a validator sees that another misses a block, he sends the data, but efficiently to avoid redundant network traffic.
Test results, protocol skills and transactions per second
The tests show that Starfish is stable and robust. Dem Whitepaper according to the average and worst confirmation times remain even with attacks within the borders. It surpassed Other non-certified DAG-BFT protocols in communication efficiency.
Starfish also builds on the Mystancei protocol and uses LEADER blocks as DACs to check the Data availability. This mechanism keeps the byte-pro-transaction costs low, so it is suitable for large DLT inserts.
The performance data From Starfish reach 150,000 TPs with a latency of less than a second. It has a linear communication complexity and holds throughput with one EfficiencyFrom 10 to 100 The validator upright . It is also resistant to Byzantine behavior. This is in line with the aim of IOTA to build a fast, safe and decentralized infrastructure.
IOTA Rebased and Future Plans
Starfish will be integrated into IOTA in the second quarter of 2025 after the rebassed mainnet upgrade. How From CNF reported will be rebassed IOTA in a complete Decentralized Layer 1 network with over 50 validatorstransform use the delegated proof-of-stake (DPOS) and the users will be able to earn stacking rewards between 10% and 15%.
As CNF reportedrebassed transaction fees and IOTA smart contracts (ISC). These intelligent contracts are currently being tested and are already active in test environments. ISC is also compatible with the Ethereum Virtual Machine (EVM) so that you can develop applications on the IOTA platform.
The IOTA Foundation has set up a public test network in which developers and users can try out the new functions. This ensures that the network is ready for the transition and that all problems can be solved before the Mainset goes live.
The MultiChain Wallet provider Nightly app said that Iota is building a strong basis for its web3 presence. As we described in our last article, Iota has a two -layer structure. Layer 1 supports smart contracts that are written in the Move language, and layer 2 enables EVM and solidity-based applications.
Nightly App reportedalso About progress in several teams. The Node team worked on the performance optimization and monitoring of the infrastructure. The Consensus team developed Starfish to accelerate transactions in environments with high traffic. The Smart Contract team improved security by introducing the Stardust Indexer, a tool that follows the activities on the chain.
Tooling and Devops teams worked with the community to test browser extensions and backend systems. This will ensure a smooth start of Rebased and provide the network for broad acceptance.
