Detailed description

The efficiency of decentralized book systems like Bitcoin and Ethereum has always been a challenge. It is usually measured by three major factors: scalability, throughput, and latency. Scalability refers to how the system capacity is increased by adding more physical resources. Throughput measures the volume of transactions for a given period of time, where most current solutions attempt to improve such as NEO, EOS, etc. Latency measures the processing time of any single transaction. In current blockchain based systems, the block generation rate is the main latency bottleneck. Off-chain processes such as state channels are the most recent work that can integrate partial inbound transactions, reducing latency. Unfortunately, the state channel introduces more issues at the same time, such as cross-channel synchronization, which makes the state channel unavailable for full adoption of current blockchain solutions.

In order to solve the efficiency problem, we proposed an end-to-end solution called ALZA, which links the dedicated high-throughput blockchain with self-organizing payment fields. This mechanism allows arbitrary set of users to create payment fields that process extremely low latency transactions within each field. Therefore, users can make transactions almost immediately. Since all transactions are conducted within fields, transaction costs will be reduced by several orders of magnitude. In addition, ALZA distributes main ledger to each client through an innovative replication mechanism. Therefore, the system will be significantly more robust to blockchain system failures. In theory, ALZA can complete millions of transactions in one second, which naturally supports high-frequency trading.


Obviously, there is a gap between usability and the way Bitcoin works today. Industries have brought up this question several times: What does it take to scale the blockchain?

The limitations can be categorized as follows: 

  • Speed of transaction processing. The block generation and consensus mechanism bottlenecks the transaction speed, it is an infrastructure level tradeoff. 
  • Cost of processing. In the blockchain, participants help to maintain and update shared ledgers and share maintenance costs among participants instead of having one entity directly bear the costs and then charging one entity. In this sharing of responsibilities, participants can see the direct costs of increasing system operations. 
  • Lack of governance. As many approaches trade security for speed, the risk of the shared ledger increases. Governance structures can improve the safety of ablockchain structure (for example, by the involvement of a broad spectrum of stakeholders) or weaken it (for example, by limiting the decision making participants). 
  • Privacy. In some blockchain system, all nodes have access to a copy of the ledger and may, if allowed, see all transactional history. However, in applying blockchain technology in the practice, participants may not want or be permitted to provide full visibility of the data. In such cases, access to information may be restricted.


The ALZA system aims to provide practical solutions to the about limitations by establishing a self-sustained and coherent infrastructure. It smoothly hybrids on-chain and off-chain solutions, which further addresses the above limitations. In summary, we make the following contributions.

  • ALZA ledger block – a dedicated chain block which optimized for dPOS consensus. This fundamental building block helps the entire system reach sequential performance to handle high transaction volume.
  • Off-chain transaction mechanism named Self-organizing Payment Field. It provides ultra low latency and high fault tolerant transaction functionality. In addition, it summarizes local high frequency payments into batches, which reduces transaction cost to several order of magnitude.
  • Privacy controlling module named Privacy Sentinel, which provide full data ownership with privacy and security.
  • Data validation and recovery system called Redundant Array of Satellite Infrastructure (RaFi). It provides ultimate availability as well as high trustworthiness to the overall system.


Authorization only transaction
Off-chain payment fields authorize an amount between nodes but the transaction item does not settle until a later time. This allows instant transactions processing within the fields and automatically reconcile across all participants.

All transactions details will be encoded within payment fields before sync back to the supernode, which will prevent highly sensitive information (eg. PII data) leaked to the public.

Pushing the transaction process to the off-chain payment fields allows us to increase transaction volume by establishing more payment fields proportionally. Therefore, the decentralized network's processing limit does not apply.

RaFi (Redundant Array of Satellite Infrastructure) is a distributed self-replicating storage system that provides data storage for DApps deployed on ALZA blockchain.
