This modifies some recently-updated modules to use a valid prerelease version so they can be used in require statements in consumer code that is also under development. Several commits are needed since there is a dependency chain that involves transitive deps. The updated direct dependencies are as follows: - github.com/decred/dcrd/blockchain/stake/v4@v4.0.0-20210129181600-6ae0142d3b28 - github.com/decred/dcrd/blockchain/v4@4.0.0-20210129181600-6ae0142d3b28 - github.com/decred/dcrd/dcrutil/v4@v4.0.0-20210129181600-6ae0142d3b28 - github.com/decred/dcrd/hdkeychain/v3@v3.0.0-20210129181600-6ae0142d3b28 - github.com/decred/dcrd/txscript/v4@v4.0.0-20210129181600-6ae0142d3b28 |

txscript
Package txscript implements the Decred transaction script language. There is a comprehensive test suite.
This package has intentionally been designed so it can be used as a standalone package for any projects needing to use or validate Decred transaction scripts.
Decred Scripts
Decred provides a stack-based, FORTH-like language for the scripts in the Decred transactions. This language is not Turing complete although it is still fairly powerful.
Installation and Updating
This package is part of the github.com/decred/dcrd/txscript/v3 module. Use
the standard go tooling for working with modules to incorporate it.
Examples
-
Standard Pay-to-pubkey-hash Script Demonstrates creating a script which pays to a Decred address. It also prints the created script hex and uses the DisasmString function to display the disassembled script.
-
Extracting Details from Standard Scripts Demonstrates extracting information from a standard public key script.
-
Manually Signing a Transaction Output Demonstrates manually creating and signing a redeem transaction.
-
Counting Opcodes in Scripts Demonstrates creating a script tokenizer instance and using it to count the number of opcodes a script contains.
