Taxa: Pave the Way for Blockchain Mass Adoption


In 2014, Ethereum was announced. 4 years later, the hype about crypto economy has reached new peaks.

Is blockchain ready for real-world adoption?

Not yet…

According to CoinDesk, as of June 2018, the Top 5 Ethereum DApps by Daily Active Users are: 1. Idex: 6,479; 2. ForkDelta: 2,221; 3. Bancor: 560; 4. CryptoKitties: 408; 5. LocalEthereum: 236.

Scalability is certainly a major roadblock for blockchain’s mass adoption. We’re happy to see projects arise to resolve blockchain’s scalability bottleneck, with approaches such as DPoS, sharding and ofl- chain state channels.

This interest in TPS leads into our second question:

Is increasing TPS all we need to bring more usages for blockchains?

Even if we reach 1 million TPS, the individual smart contracts are still very simple programs. Factors that limit the usage and value of smart contracts include:

  • Time resource: As just one example, Ethereum processes 2-digit transactions per second as of June 2018. Because of that, the execution time for each transaction and its associated smart contract is Smart contracts on Ethereum lack the time capacity to execute complex business logics or intensive computations.
  • Space resource: Due to the current design of major blockchains, all the transaction information, including smart contract input, must be packed into Say, the entire Ethereum blockchain is only ~450 GB (in less than 3 years), and each block size is only 20–30 KB. There’s no su±cient space resource for heavy data.
  • Privacy protection: Due to the consensus mechanism, each node has access to each byte of the code and data of a smart contract executed on Due to the lack of data privacy, one can hardly build significant, real-world applications on blockchain.


Yet, increased TPS won’t  fully  resolve  the  aforementioned limitations. It is certainly necessary to improve blockchain’s horizontal performance in terms of TPS. On the other hand, to make blockchain massively usable, there’s much more to be done with its vertical performance—the ability of handling intensive computation and heavy data, while ensuring a reasonable level of privacy.


Introducing: Taxa

Taxa is a Layer 2 infrastructure that brings performance, privacy and usability to every blockchain and their DApps.

Hyper Smart Contracts

Leveraging the state-of-the-art hardware-based trusted computing technology and a PBFT-derived consensus mechanism, Taxa aims at becoming the universal logic layer that enables high-performance, privacy-preserving, and highly-developable Hyper Smart Contracts for all.

Layered Design

At high level, Taxa is introducing a layered design to move on-chain logic processing to off-chain.




In this layered design, Taxa executes stateless, high-performance, privacy-preserving smart contracts, while interacting with the consensus layer of public blockchains to store the immutable, persistent states.


Taxa brings the core functionalities to every blockchain and DApp:

  • Performance: Computing capabilities ft. low overhead at an accelerated speed allow applications to perform complex business logics.
  • Privacy: Hardware level isolation with secure I/O channels guarantees the sensitive data’s security in storage, transmission and execution, concealing DApps’ private info from the public and the
  • Reliability: A fault-tolerant consensus model is married with trusted hardware to guarantee the integrity, confidentiality and
  • Developability: Rich SDK support, and a general-purpose, developer-friendly interpreter environment for flexible industrial use.

With Taxa, developers are able to unlock whole new use cases in analytics, fintech, advertising, AI, identity, healthcare, legal, and more!

Just imagine!
