📌 Proof of Elapsed Time Summary
Proof of Elapsed Time, often shortened to PoET, is a consensus mechanism used in blockchain networks to decide who gets to add the next block of transactions. It relies on trusted computing environments to randomly assign wait times to participants. The participant whose wait time finishes first gets to create the next block, which helps ensure fairness and energy efficiency compared to systems that require lots of computing power.
🙋🏻♂️ Explain Proof of Elapsed Time Simply
Imagine a group of friends drawing straws to decide who gets the next turn in a game. Each person waits a random amount of time, and the one who finishes waiting first gets to play. This way, everyone has an equal chance without needing to race or use extra effort.
📅 How Can it be used?
PoET can be used in supply chain applications to efficiently and fairly validate new records without high energy costs.
🗺️ Real World Examples
A food tracking platform uses PoET to let different suppliers add updates to a shared blockchain. Because PoET assigns wait times randomly using secure hardware, every supplier has an equal chance to record their data, reducing the risk of any one company dominating the system.
A digital identity network uses PoET to let various trusted organisations verify and add identity credentials. By relying on random wait times, the process remains fair and energy-efficient, making it suitable for large-scale identity management.
✅ FAQ
What is Proof of Elapsed Time and how does it work?
Proof of Elapsed Time is a way for blockchains to decide who gets to add the next group of transactions. Instead of making everyone race to solve puzzles or use lots of electricity, it gives each participant a random waiting period. Whoever finishes their wait first gets to add the next block. This keeps things fair and uses much less energy.
Why is Proof of Elapsed Time considered energy efficient compared to other methods?
Proof of Elapsed Time does not require participants to do heavy calculations or run powerful computers all the time. Instead, it relies on random wait times, so computers can stay idle until it is their turn. This saves a lot of electricity compared to methods like Proof of Work, which need constant computing.
Can anyone participate in a blockchain that uses Proof of Elapsed Time?
To take part in a Proof of Elapsed Time system, you need access to trusted computing environments that can prove your wait was legitimate. Not everyone may have the right hardware, but it is designed to be more accessible and fairer than some other systems, especially for people who do not have powerful computers.

Decentralised Key Management
Decentralised key management is a way to handle digital keys, such as those for encryption or signing, without relying on a single central authority. Instead, the responsibility for creating, storing, and sharing keys is spread across multiple people or systems, making it harder for any one person or group to compromise the entire system. This approach improves security and resilience, as there is no single point of failure and users have more control over their own keys.
Referral Platform
A referral platform is an online system that helps businesses encourage their customers to refer new clients by making the process easy and rewarding. It typically tracks referrals, manages rewards, and provides tools for sharing referral links. Companies use referral platforms to grow their customer base by leveraging recommendations from existing users.
AI for Anti-Poaching
AI for anti-poaching refers to the use of artificial intelligence technologies to help detect, prevent, and respond to illegal hunting and wildlife trafficking. These systems can analyse data from cameras, drones, sensors, and other sources to spot suspicious activity or patterns that suggest poaching. By using AI, conservation teams can react more quickly and efficiently to protect endangered animals and their habitats.
Personalised Feed Generator
A personalised feed generator is a system or tool that creates a customised stream of content for each user based on their interests, behaviour, or preferences. It gathers data about what a user likes, interacts with, or spends time on, then uses this information to select and organise content specifically for them. This helps users quickly find the information, news, or updates that matter most to them.
Incident Management Framework
An Incident Management Framework is a structured approach used by organisations to detect, respond to, and resolve unexpected events or incidents that disrupt normal operations. Its purpose is to minimise the impact of incidents, restore services quickly, and prevent future issues. The framework typically includes clear processes, defined roles, communication plans, and steps for learning from incidents to improve future responses.
