Researching the data miners assemble before hashing requires a clear boundary. The boundary used below covers candidate transactions, coinbase transaction and block header fields.
Protocol concepts become useful when they are tied to observable block, transaction and hash data. Keep consensus rules separate from pool accounting or hardware marketing terms.
Candidate Transactions
A decision involving candidate transactions should include a baseline and a review trigger. The baseline describes ordinary conditions; the trigger defines when the analysis must be repeated. Include coinbase transaction in that trigger when it can materially change the interpretation of candidate transactions.
- Evidence: a dated record for candidate transactions.
- Cross-check: compare it with coinbase transaction.
- Review trigger: repeat the check after a material change affecting candidate transactions.
Coinbase Transaction
Define coinbase transaction before comparing it with block header fields. Identify the unit or rule behind coinbase transaction, capture a dated value where one exists, and state whether the value is measured, calculated or supplied by another party. That distinction determines how confidently coinbase transaction can support the article’s conclusion.
- Evidence: a dated record for coinbase transaction.
- Cross-check: compare it with block header fields.
- Review trigger: repeat the check after a material change affecting coinbase transaction.
Block Header Fields
The role of block header fields is best understood through a controlled comparison. Hold unrelated inputs constant, change one relevant condition and observe the response. Then check whether candidate transactions moved in the expected direction. A mismatch is a prompt to inspect the model, not to hide the data.
- Evidence: a dated record for block header fields.
- Cross-check: compare it with candidate transactions.
- Review trigger: repeat the check after a material change affecting block header fields.
The data miners assemble before hashing: evaluation sequence
- Write the exact decision involving candidate transactions.
- Collect coinbase transaction using the same observation period.
- Test how the conclusion changes when block header fields moves.
- Save the source values, conversions and date of review.
