How Does a Pool Operator Ensure That a Rejected Share Is Genuinely Invalid and Not Due to a Server Error?
The pool operator ensures the rejection is genuine by having a robust and highly-tested share validation mechanism on the Stratum server. The server performs a full cryptographic check on the submitted proof-of-work against the current block template and the pool's difficulty target.
If the share fails this check, it is rejected. Error logs and automated monitoring systems track server performance to rule out software bugs as the cause.
Glossar
Pool Operator
Function ⎊ The pool operator is the centralized entity responsible for coordinating the collective computational power of individual miners within a mining pool to increase the probability of discovering a block.
Error
Detection ⎊ An error within cryptocurrency, options, or derivatives trading frequently manifests as a discrepancy between expected and actual execution prices, or a failure in order routing logic.
Server Performance
Latency ⎊ Server performance within cryptocurrency, options trading, and financial derivatives is fundamentally defined by latency ⎊ the time delay in data transmission and order execution.
Share Validation Mechanism
Attestation ⎊ Share validation mechanisms, particularly within decentralized finance, represent a critical layer of trust establishment, moving beyond traditional centralized authorities.
Share Validation
Attestation ⎊ The concept of Share Validation, within cryptocurrency derivatives, options trading, and broader financial derivatives, fundamentally concerns the cryptographic verification of ownership and authenticity of underlying assets or derivative contracts.
Share Rejection
Rejection ⎊ The term "Share Rejection," within the context of cryptocurrency derivatives, options trading, and financial derivatives, denotes the failure of a market participant's request to execute a trade at a specified price and quantity, typically due to price volatility exceeding acceptable parameters or order book constraints.
