github.com/davecgh/btcd/blockchain/standalone (go): Package standalone provides standalone functions useful for working with the Decred blockchain consensus rules.  The primary goal of offering these functions via a separate module is to reduce the required dependencies to a minimum as compared to the blockchain module.  It is ideal for applications such as lightweight clients that need to ensure basic security properties hold and calculate appropriate vote subsidies and block explorers.  For example, some things an SPV wallet needs to prove are that the block headers all connect together, that they satisfy the proof of work requirements, and that a given transaction tree is valid for a given header.  The provided functions fall into the following categories:  Errors returned by this package are of type standalone.RuleError.  This allows the caller to differentiate between errors further up the call stack through type assertions.  In addition, callers can programmatically determine the specific rule violation by examining the ErrorCode field of the type asserted standalone.RuleError.
