With the development of blockchain technology and the popularity of digital currencies, more and more blockchain projects and exchanges require high-performance, low-latency computing resources. Hong Kong cloud servers have become a popular choice in the blockchain industry due to their superior geographical location and network conditions. Combined with digital currency payments such as USDT, it can provide a one-stop blockchain deployment solution for global customers.

Advantages of Hong Kong Cloud Servers

Hong Kong is a core hub for global interconnectivity, with a large number of international submarine cables converging here. Therefore, Hong Kong’s network quality is excellent, with an average latency of less than 50ms and a packet loss rate of less than 1%. This is critical for latency-sensitive blockchain applications. In addition, Hong Kong is located at the center of the Asia-Pacific region, connecting the mainland and overseas markets, allowing blockchain projects to better serve global users.

Well-known cloud computing vendors such as Alibaba Cloud, Amazon AWS, and Microsoft Azure have data centers in Hong Kong, providing secure and reliable elastic computing, storage, networking, and other services. Blockchain projects can leverage these resources to quickly build highly available node and API clusters. For example, using high-IO SSD cloud disks can significantly improve the read and write speed of blockchain data.

USDT Payment Integration Process

Most Hong Kong service providers support USDT payments, which provides convenience for global blockchain projects. USDT is a blockchain-based digital dollar, pegged 1:1 to fiat currency, with extremely high liquidity. The payment process is roughly as follows:

  1. Register and verify on the Tether official website to obtain a USDT wallet address
  2. Purchase equivalent USDT on an exchange or OTC platform and transfer it to the above wallet address
  3. Select USDT payment in the cloud service provider’s management backend and fill in the USDT wallet address
  4. After the cloud service provider confirms the receipt of payment, the account will be credited with the corresponding amount

The entire process takes no more than 10 minutes. Cloud service providers usually provide a real-time exchange rate query interface, for example:

GET https://api.cloudprovider.com/v1/exchange_rate?currency=USDT

Return example:

    "currency": "USDT",
    "rate": 7.08,
    "updated_at": "2022-03-15T10:00:00Z"

This means 1 USDT can be exchanged for 7.08 RMB. The exchange rate changes in real-time, and automatic billing can be achieved through this interface.

Application in Exchanges

Cryptocurrency exchanges have extremely high requirements for system performance and need to handle millions of concurrent transactions. Traditional monolithic architectures can hardly meet this requirement. Adopting multi-node clustered deployment can significantly increase the throughput of the trading matching engine. The architecture is as follows:

  • Users access the trading API through a load balancing gateway
  • The API server forwards requests to the matching engine cluster
  • Engine nodes synchronize order books and trade data through memory queues
  • Asynchronously persist data to distributed KV storage
  • Push real-time market data to users via WebSocket

Exchanges can deploy a dozen or so engine nodes on Hong Kong cloud servers, each with 8 cores and 16G memory. By adopting high-performance in-memory databases such as Redis Cluster, it can easily cope with peak trading volumes. The architecture diagram is as follows:

               |  Gateway  |
                /    |    \
        +-------+  +-+---+  +-------+  
        | API 1 |  | API |  | API N |
        +-------+  +-----+  +-------+
            |        |         |     
       +---------+  +-+------+  +---------+
       | Engine1 |  | Engine |  | EngineN |
       +---------+  +--------+  +---------+
              \       |        /
           |   Redis Cluster  |  

Deployment of Blockchain Nodes

Many blockchain foundations such as Ethereum, BSC, and Polygon support deploying validator nodes on cloud servers. Taking Polygon as an example, the node deployment process is roughly as follows:

  1. Apply for Polygon test TOKEN
  2. Create two instances for Sentry node and validator node, recommended configuration is 4 cores 8G, enable SSD cloud disk
  3. Install Polygon Heimdall and Bor clients on the Sentry node
  4. Synchronize block data and configure the connection with the validator node
  5. Deploy the Polygon validator program on the validator node
  6. Stake a certain amount of TOKEN to participate in consensus and receive block rewards

Using Hong Kong nodes can greatly reduce the network latency of validators, making the validation process and block propagation faster. Hong Kong is also relatively friendly in terms of laws and policies, and will not create obstacles for compliant node operations. It is foreseeable that more blockchain projects will choose Hong Kong nodes in the future.


Hong Kong cloud servers + USDT payment is the perfect combination for the blockchain industry. On one hand, Hong Kong’s network conditions and legal environment are very suitable for deploying blockchain applications with high performance requirements. On the other hand, USDT allows global users to easily purchase Hong Kong cloud resources. It is believed that in the foreseeable future, more and more blockchain projects will land in Hong Kong, jointly promoting the development of the industry.
