Three great tools

Decentralized Storage

Decentralized Rights Affirmation

Decentralized Search Engine

NETTA is a decentralized operating system that protects Internet information sovereignty

Unlike Blockchain today that only traces ownership,
Netta is able to protect digital right, including ownership, copyright, rights to use and rights to distribute,
through its novel techniques on semantic analysis, dataflow graph ledger, and parallel consensus processing.
Through its own decentralized search engine with the capability of information rights affirmation ,
Netta revolutionizes existing advertisement model and distributes benefits to all participants.


A new generation of decentralization achieving 100,000 TPS by concurrent data flow graph

1.Netta's novel ledger is a computational framework that consists of a data flow graph and a graph computation engine. It achieves concurrent graph computation with partial order, which makes a breakthrough to DAG that can only record information through graph.

2.Each node in the data flow graph is a transaction account. Smart contracts are event-driven data ows in the ledger. Once the data stream is triggered, the corresponding smart contract is executed.

3.The data flow graph ledger is based on a novel asynchronous PGB consensus algorithm. The predecessor-based random selection BFT algorithm is highly concurrent and resistant to double spending.

4.In a 3000-node public network testing environment, the data flow graph ledger achieves 100,000 transactions per second.

New decentralized storage framework that operates on ciphertext. Through engineering it solves the impracticality of homomorphic encryption with performance superior to IPFS

1.Netta solves the dilemma that plaintext storage cannot protect privacy and ciphertext storage cannot process content. People try to use homomorphic encryption algorithms to solve this problem, but unfortunately these algorithms are still impratical. Through a novel engineering approach, Netta makes it practical .

2.Netta compares is able to compare a digital asset against the the whole Internet based on the hash of semantic segments in ciphertext. Such comparison can quantify the similarity in terms of semantics. Through the comparison,the storage in Netta does eliminate redundancy that is widespread in IPFS.

3.The decentralized storage structure consists of two trees: a semantic ciphertext hash tree (SSRAG) and a leaf node Merkel tree (SRMerkleT). It has features of tamper resistance, high concurrency, constant access time, and fast missing path localization.

Precise information sovereignty protection through semantic comparison of stored content with ledger-based consensus

1.Different from the existing blockchain technology that just records ownership, Netta can protects four different types of rights through semantics analysis: ownership, copyright, use right and distribution right, which leads to fair distribution of reputational and financial benefits.

2.The data flow graph ledger supports the rich expression and computation of semantics. With first-order predicate logic, it is able to express and store the semantic information of digital assets without loss.

3.Based on semantic similarity, nodes in Netta can reach consensus on the original work percentile of any digital asset. Based on how much a digital asset quotes from others, the account that owns the digital asset shares its benefit with other accounts. The copyright credit system is a data flow graph ledger and the benefits can be automatically computed based on such graph whenever a digital asset receives benefit.

A native decentralized search engine without redundancy

1.Different from the mainstream topical search models, Netta offers more comprehensive and accurate search based on sociology and cognitive index structure.

2.The search engine can search software code by software code, and by function descriptions.

3.Netta eliminates redundancy so the search engine does not give redundant web contents .

4.Netta's novel ranking algorithm NettaRank is based on information influence that fairly reflects the true value of information.

Netta's smart contract and their interaction are Turing-complete.

1.Not only smart contracts are Turing complete, the collaboration mechanism among smart contracts is also Turing complete. Each smart contract is an executable unit, and multiple smart contracts can form an executable group. Within the group, the execution path between smart contracts may have branches and loops.

2.The execution result of smart contract $A$ can be used as the trigger condition of smart contract $B$. Thus the execution of smart contracts can trigger the execution of one or multiple smart contracts and lead to cascade executions.

3.Based on the data flow diagram where data and code are integrated, Netta can realize complex high-dimensional functions based on cooperation of multiple groups of smart contracts with single functionality .

Three Main Components


NtaAgents are autonomous agents that are executed on users’computing devices such as laptops and smartphones. The functionality of a NtaAgent includes publishing information over internet, managing local digital resource, using DApps, collaborating with other NtaAgents to form an agent alliance.


In order to achieve information sovereignty Netta needs a large number miners to contribute decentralized storage. An NtaStorage unit stores a partial semantic hash tree that ...


Besides re-organizing internet information using NtaStorage, Netta needs miners to verify information transactions, record and disseminate transaction history, which leads to consensus.

Netta Applications
