A joinable pool is a group of users who combine their computing resources to collectively mine or validate transactions on a blockchain network. Instead of mining individually, participants in a joinable pool work together to increase their chances of earning rewards.When users join a pool, they share their processing power and receive a proportional share of the rewards based on the amount of work they contribute. This model helps smaller miners compete against larger operations by reducing the variance in rewards; rather than waiting for a long time to earn a block reward, participants receive smaller, more frequent payouts.Joinable pools often have an easy registration process, allowing users to quickly connect their mining hardware or software. In addition, they provide several features, such as real-time statistics, payment tracking, and community support, making it more accessible for newcomers. Overall, joinable pools offer a collaborative approach to mining, making it more efficient and less daunting for individual users to participate in blockchain networks.
