Blockchain done right.
Hybrid Distributed Ledger.
ParallelChain™ is Digital Transaction’s high-performance double-hybrid blockchain system, with real-time confirmation of less than 0.01 second and transaction speed greater than 100,000 transactions per second (TPS). Enterprises can build custom applications on the ParallelChain™ platform and seamlessly migrate their existing Ethereum or Hyperledger applications onto the platform.
Scalability, security and decentralization. Because of their technical and infrastructural limitations, blockchain platforms have had to compromise on at least one of these facets to satisfy the rest; this is known as the Blockchain Trilemma. ParallelChain™'s patent-pending technology changes all that, making it the first truly 'business-native' blockchain, ready to power today's real-world applications and scalable to transform enterprises' digital transformation initiatives.
Combines the best features of public and private blockchains while encompassing both permissioned and permissionless functionalities.
Built to handle the massive quantity of data generated by new and emerging technologies such as Intelligent IoT and 5G.
The only blockchain in the world with such capability
Supports the seamless migration of Ethereum and Hyperledger applications onto the platform.
The first and currently only blockchain that complies with the EU's GDPR and other international data protection laws.
Anyone can 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.
Supports 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 ≤ 0.01s, allowing for immediate confirmation of updates.
Efficient software design removes dependence on costly hardware (topline servers, semiconductor bulk memory, GPU accelerator) to achieve real-time responses.
Every blockchain claims to be immutable, but how true is this? When forked chains can be deleted and blocks can be altered or removed as a result of collusions among a majority of endorsed nodes, such claim becomes questionable.
Blockchain immutability alone is not sufficient to establish trust. Trust can only be earned and maintained when immutability is continuously proven. ParallelChain™ enables participants to repeatedly and randomly verify the immutability of blocks without compromising the privacy of data owners.
The world's second-largest cryptocurrency platform by market cap.
A permissioned blockchain infrastructure developed by the Linux Foundation, and contributed by IBM and Digital Asset.
Ability to forget
Data persisted on ParallelChain™ can be deleted, allowing for the 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? What are the environment requirements for running it?
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 or Alibaba Cloud, or in customers' premise servers. The ParallelChain™ should be able to connect to the internet to request a license from Digital Transaction's licensing server.
The fully tested Linux is Ubuntu 18.04x86-64.
First-generation 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 blockchains 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 hybrid permissioned and permissionless model ensures that the data is immutable and tamper-proof, avoiding the cumbersome infrastructural issues and complex requirements other existing blockchains face.
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 Digital Transaction read or receive my data on ParallelChain™? Is my data secure?
Digital Transaction cannot read or receive your data unless your allow us access to your ParallelChain™. Your data is secure and is always under your own control.
ParallelChain™ only sends basic system configuration and statistics information to Digital Transaction's licensed server through the Internet to request software license. The data on your application is never sent to us.
What application programming interfaces can I use to connect to ParallelChain™?
RESTful API and gRPC API.
Can ParallelChain™ scale up for workload peaks? Is there any downtime during scaling up?
The servers that run smart contracts and 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 to contact Digital Transaction to customize ParallelChain™ for changes of any 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 and/ or add smart contracts without having to change or modify the ParallelChain™ software itself.
Can ParallelChain™ support my applications' query and scan functions?
You can write smart contract codes 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 on Ethereum is quite complex, in that it requires one to define contracts using Solidity and then perform actions when acting on the contract. Will your SDK present a more user-friendly interface to developers?
Compared to other blockchains' asynchronous programming model which does not really offer durability, 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 to the applications’ invocation request. The 0.01-second transaction time makes real-time interactive applications on blockchain possible.
