This modifies the NextBlock function to account for changes made to the block height or previous block hash in munge functions and update the commitments in all votes accordingly. |

Package chaingen provides facilities for generating a full chain of blocks.
Overview
Many consensus-related tests require a full chain of valid blocks with several pieces of contextual information such as versions and votes. Generating such a chain is not a trivial task due to things such as the fact that tickets must be purchased (at the correct ticket price), the appropriate winning votes must be cast (which implies keeping track of all live tickets and implementing the lottery selection algorithm), and all of the state-specific header fields such as the pool size and the proof-of-work and proof-of-stake difficulties must be set properly.
In order to simplify this complex process, this package provides a generator that keeps track of all of the necessary state and generates and solves blocks accordingly while allowing the caller to manipulate the blocks via munge functions.
Examples
- [Basic Usage Example]
(http://godoc.org/github.com/decred/dcrd/blockchain/chaingen#example-package--BasicUsage)
Demonstrates creating a new generator instance and using it to generate the required premine block and enough blocks to have mature coinbase outputs to work with along with asserting the generator state along the way.
