What Is the Difference between a “Share” and a “Valid Block Solution”?
A "share" is a partial proof-of-work that satisfies the pool's relatively low target difficulty, proving the miner is actively working. A "valid block solution" is a proof-of-work that satisfies the extremely high difficulty requirement of the entire blockchain network.
A valid block solution is always a valid share, but a share is almost never a valid block solution. Only a valid block solution earns the block reward for the pool.
Glossar
Block Solution
Architecture ⎊ Block Solution, within cryptocurrency and derivatives, denotes a systematic approach to constructing and managing decentralized applications, often leveraging smart contracts to automate complex financial workflows.
Valid Block
Confirmation ⎊ A valid block, within a blockchain context, represents a data package cryptographically appended to the chain following consensus protocol stipulations, signifying transaction finality and state updates.
Valid Block Solution
Definition ⎊ Valid Block Solution refers to a cryptographic hash generated by a miner that meets the network's current difficulty target.
Finding a Valid Block
Verification ⎊ Finding a valid block, within distributed ledger technology, represents the consensus-driven confirmation of a batch of transactions, establishing its immutability and inclusion in the blockchain.
