Blockchain done right.
Hybrid Distributed Ledger.
ParallelChain™ is DTL's high performance hybrid private blockchain system, with real time updates and a speed of up to 100,000 Transactions Per Second (TPS). Businesses can build custom apps on the ParallelChain™ platform or port existing Ethereum or Hyperledger apps to the platform and enjoy higher TPS and immediate updates.
Demo ParallelChain™ on your local machine
Provable immutability, trust, and speed. Because of technical and design limitations, blockchain platforms have hitherto had to compromise on at least one of these goals to satisfy the rest. ParallelChain's patent pending innovations changes all that, making it the first truly 'business-native' blockchain, ready for today's real-world applications and scalable to power tomorrow's.
Infinitely configurable to combine the best features of public, and private blockchains.
Built to handle the massive quantity of data generated by new and emerging technologies such as intelligent IoT and 5G.
Designed from the ground-up to play nice with other blockchain platforms and technologies.
The first and currently only blockchain that complies with the EU GDPR Privacy Ordinance
Anyone can read read and endorse transactions.
Anyone can read but has to seek permission to endorse transactions.
Any member of the consortium can read and endorse transactions.
Any member of the consortium can read, but has to seek permission to endorse transactions.
Close-to-perfect parallelism avails an unlimited number of endorsed parties with zero speed degradation.
Over 100,000 transactions per second (TPS) for one ParallelChain instance. Scales to n * 100,000 TPS for n ParallelChains.
Low latency of ≤ 50ms, allowing for immediate confirmation of updates.
No need for dedicated hardware
Efficient software design removes dependence on costly hardware (topline servers, semiconductor bulk memory, GPU accelerator) to achieve real-time responses.
The world's second-largest cryptocurrency platform by market cap.
Permissioned blockchain infrastructure originally contributed by IBM, Digital Asset, and the Linux Foundation.
Trust is only earned when it can be independently validated and proved. ParallelChain enables participants to verify the immutability of the chain for themselves.
Ability to forget
Data persisted into ParallelChain can be deleted, allowing removal of time-sensitive data, or data under court-order for removal.
Individual endorsers cannot alter persisted records without notifying all parties, eliminating the possibility of data tampering by collusion.
No data leakage
Third parties can mathematically verify the integrity of the blockchain without reading the entire, potentially sensitive, data.

Frequently asked questions
Is ParallelChain a service or a software? Requirements for the running environment?
Parallelchain™ is a software product.
It runs on Linux. The Linux nodes can be a virtual machine in private or public cloud such as AWS/Azure/Alibaba Cloud, or in premise servers of customers. The ParallelChain™ should be able to connect to the internet to request a license from DTL"s licensing server.
The fully tested Linux is Ubuntu 18.04x86-64.
The "older" blockchain technologies like Hyperledger and Ethereum use mining to reach consensus. How does ParallelChain™ avoid such kind of operation?
Mining (or proof of work, PoW) is usually for public blockchain open for anyone to join. PoW protects the "decentralization" and hence the "security" of the blockchain system against attacks such as Sybil attacks. incentive economy models so built around that. However, this causes a lot of problems for most business applications. Hyperledger-like blockchain use consortium which leads to heavy dependencies.
ParallelChain™"s unique combined permissioned and permissionless design ensures the data and logic immutability and tamper proof without the heavy problems and requirements like other blockchains.
What is the data security? Is it publicly readable like public blockchains?
ParallelChain™ is a private/permissioned blockchain. Its read/writes are through invoking smart contracts. Access to invoke smart contracts are controlled and permissioned.
Application clients or programs need to have an account with an access ID and credential (a password like text string) to authenticate itself and invoke smart contract to ParallelChain™. The ParallelChain™ instance's system administrators create accounts and control access rights of accounts to smart contracts.
ParallelChain™ can be connected from the Internet or configured to be available to internal network only, depending on the configuration. Connectioins to ParallelChain™ can be limited by the traditional firewall/network isolation as well.
Can DTL read/receive my data on ParallelChain™? Is my data secure?
DTL cannot read/receive any data unless the customer"s ParallelChain™ opens access to DTL. Your data is secure and is always under your own control.
ParallelChain™ only sends basic system configuration and statistics information to DTL"s license server through the Internet to request software license. The application data are never sent to DTL.
What interfaces do applications use to connect to ParallelChain™?
ParallelChain™ provides RESTful API and gRPC API.
Can ParallelChain™ scale up for workload peaks? Any downtime during scaling up?
The servers to run smart contracts and run the underlying Key/Value store can be dynamically added by the system administrator to increase the throughput. The scaling up is done online without having to shut down the ParallelChain™ (zero offline time).
After the workload pressure is lower, the ParallelChain™ system can be shrunk online to save resources and cost.
Do I need DTL to customize ParallelChain™ for changes of blockchain functions?
No, for most of the time.
Your application logic in blockchain should be implemented as smart conrtacts. The smart contracts are implemented on top of ParallelChain™ instead of being part of the ParallelChain™. You own the IP of the smart contracts you write, and you can always upgrade/add smart contracts, without having to change or modify the ParallelChain™ software itself.
Can ParallelChain™ support my applications" query/scan functions?
You can write smart contract code to support the logic/functions.ParallelChain™ provides a programming model of combined Key/Value store with ACID semantics. Common Key/Value store programming techniques apply here. ParallelChain™ APIs also support efficient searching against keyword, regular expression or JSON matching for values in a key range and scanning of key/values. The ACID semantics make the programming much easier than on normal Key/Value stores.
The programming models like those in Ethereum is quite complex requiring one to define contracts using Solidity, then perform actions when acting on the contract. It"s quite hard to relate to app development. Will your SDK present an easier interface to developers?
Compared to other blockchains" asynchronous programming model which does not really provide the D (Durability) property, ParallelChain™ gives an RDBMS like development experience by providing synchronous programming model with real ACID properties for applications.
Transactions are confirmed on blockchain immediately before replying the applications’ invocation request. The 0.1 second transaction time makes real interactive applications on blockchain possible.
