📌 Proof of Capacity Summary
Proof of Capacity is a consensus mechanism used in some cryptocurrencies where miners use their available hard drive space to decide mining rights and validate transactions. Instead of using computational power, the system relies on how much storage space a participant has dedicated to the network. This approach aims to be more energy-efficient than traditional methods like Proof of Work, as it requires less ongoing electricity and hardware use.
🙋🏻♂️ Explain Proof of Capacity Simply
Imagine a competition where everyone gets a ticket for every gigabyte of space they offer. The more space you provide, the more tickets you have, and the better your chances of winning. Instead of racing to solve puzzles quickly, you prepare your tickets in advance and wait to see if you have the winning one when the time comes.
📅 How Can it be used?
A project could use Proof of Capacity to secure a blockchain system while keeping electricity costs low.
🗺️ Real World Examples
Burstcoin uses Proof of Capacity to allow users to mine new coins by allocating unused hard drive space. This means anyone with spare storage can participate in supporting the network, making it more accessible and environmentally friendly compared to systems that require powerful, specialised hardware.
Some decentralised file storage networks use Proof of Capacity to reward users for sharing their disk space. Participants earn rewards based on the amount of storage they contribute, encouraging more people to offer space and increasing the network’s total storage capacity.
✅ FAQ
What is Proof of Capacity and how does it work?
Proof of Capacity is a way for some cryptocurrencies to decide who can add new transactions to the blockchain. Instead of relying on powerful computers to solve puzzles, it uses the amount of hard drive space a person is willing to share. The more space you dedicate, the better your chances of being chosen to validate transactions. This method is designed to be much more energy efficient, as it does not need constant high-powered computing.
Why is Proof of Capacity considered more eco-friendly than other methods like Proof of Work?
Proof of Capacity uses hard drive storage instead of heavy computing, which means it consumes far less electricity. Where traditional mining can require expensive equipment running nonstop, this approach lets regular computers with spare storage participate, helping to reduce both energy costs and environmental impact.
Can anyone participate in mining with Proof of Capacity, or do you need special equipment?
One of the advantages of Proof of Capacity is that it allows almost anyone with a regular computer and some free hard drive space to get involved. There is no need for specialised or expensive mining hardware, making it more accessible for people who want to contribute to the network and potentially earn rewards.

AI Toolchain Integration Maps
AI Toolchain Integration Maps are visual or structured representations that show how different artificial intelligence tools and systems connect and work together within a workflow. These maps help teams understand the flow of data, the roles of each tool, and the points where tools interact or exchange information. By using such maps, organisations can plan, optimise, or troubleshoot their AI development processes more effectively.
AI-Based Vendor Selection
AI-based vendor selection uses artificial intelligence tools to help organisations choose suppliers or service providers. It analyses data from vendor proposals, performance records, pricing, and other factors to recommend the best matches. This approach can save time and reduce human bias in the selection process, leading to better decisions and improved value for organisations.
AI for Recycling Robots
AI for recycling robots refers to the use of artificial intelligence technologies to help robots identify, sort, and process recyclable materials more accurately and efficiently. These robots use cameras and sensors to scan items on conveyor belts, then AI software analyses the images to determine what type of material each item is made from. This allows recycling facilities to separate plastics, metals, paper, and other materials with less human intervention and fewer mistakes.
Secure Coding Standards
Secure coding standards are a set of guidelines and best practices that help software developers write code that prevents security vulnerabilities. These standards cover common risks such as data leaks, unauthorised access, and code injection. By following secure coding standards, developers reduce the chances of attackers exploiting weaknesses in software.
Stability Index
A stability index is a measure used to assess how stable or consistent something is over time. It is often used in fields like engineering, finance, and data analysis to identify changes or shifts in a system, data set, or process. By calculating the stability index, organisations can monitor trends, detect problems early, and make informed decisions to maintain or improve performance.
