Stratum: The Bitcoin Mining Protocol

The Stratum mining protocol is an essential component of the Bitcoin (BTC) network. It allows mining software to connect efficiently and securely to the blockchain. This optimizes the mining process. Developed in 2012, Stratum has become the most popular protocol used for mining bitcoins. In this post, we will delve into the definition of this technology and why it is so important for Satoshi Nakamoto’s network.

What is the Stratum mining protocol?

Stratum is a communication protocol designed to provide an optimal way to mine bitcoin (BTC). It allows miners to communicate with mining pools more effectively and securely. 

To do this, it reduces the amount of data that needs to be sent over the network. It also allows servers to easily transmit updates to miners, including new tasks or changes in mining difficulty.

The protocol was introduced by Slush Pool, a Bitcoin mining pool based in the Czech Republic. It was developed as an alternative to the original Bitcoin mining protocol, called “Getwork.” 

Its main goal was to reduce network latency and communication overhead while increasing mining efficiency.

Stratum also enables miners to detect stale blocks faster and more efficiently. This helps to reduce orphaned blocks and wasted resources. Additionally, the protocol includes a modular software library that allows miners to manage their resources more efficiently.

Finally, Stratum offers better security against denial-of-service (DoS) attacks, as well as support for multiple cryptocurrencies and alternative hashing algorithms. This allows miners to choose the most profitable cryptos to mine at any given time.

How does Stratum work?

Overall, Stratum works in the following manner:

1. With a “mining.subscribe” request, miners establish a connection with a pool server. They each share certain data, such as the IP address of their mining equipment and the wallet address intended to receive rewards;

2. The server responds with a “mining.notify” message and assigns tasks to the miners. These tasks contain information about the ongoing work, such as the block header and network difficulty. These are essential to finding the nonce, a value generated from the hash function, which allows collecting mining rewards;

3. Miners will then begin working on solving complex mathematical equations to find the nonce. When one of them finds a valid solution, they will send a “mining.submit” message to the server with the block header and the identified nonce;

4. If the solution is valid, the server will respond with a “mining.submit” message, and that miner will receive their reward from the pool. This reward will be distributed among all the miners who contributed to solving this equation. If the solution is invalid, the server will send an error message, and the miner will continue exploiting the current block in search of the correct nonce.

Why is Stratum important for the Bitcoin blockchain?

Stratum is an essential element of the Bitcoin network because it serves as the main communication standard between miners and mining pools. It is responsible for ensuring that blocks are mined efficiently and accurately.

Moreover, the protocol allows miners to communicate with each other without having to maintain a direct connection. It also facilitates efficient sharing of work among miners, allowing them to distribute the task of finding valid blocks. 

This reduces the time required to find a valid block, thereby speeding up confirmation times.

Furthermore, Stratum is an important tool for preventing malicious behavior on the network. It allows miners to detect if someone is attempting to submit invalid blocks or carry out double-spend attacks. By detecting and rejecting these blocks, it contributes to the security and reliability of the network.

Conclusion

The Stratum protocol was designed to improve the efficiency and security of the bitcoin mining process. It allows miners to receive all the information they need to start mining in a single message and for servers to easily transmit updates to miners. At the same time, it facilitates work sharing while ensuring protection against malicious actors. Overall, the first version of Stratum (V1) has proved to be more efficient and secure than the getwork protocol. This explains why it has largely replaced the latter in the Bitcoin network. Meanwhile, Stratum V2, released in October 2022, is expected to revitalize the BTC mining sector. This is essential for its widespread adoption.
