Closes #25675. This builds on the work done in #26045, addresses open feedback, adds some further improvements (most importantly usage of compact size), documentation, and an additional test. The [original snapshot at height 830,000](https://github.com/bitcoin/bitcoin/pull/29551) came in at 10.82 GB. With this change, the same snapshot is 8.94 GB, a reduction of 17.4%. This also enhances the metadata of the output file and adds the following data to allow for better error handling and make future upgrades easier: - A newly introduced utxo set magic - A version number - The network magic - The block height ACKs for top commit: achow101: ACK 542e13b2937356810bda2c41be83c3b1675e2f2f TheCharlatan: Re-ACK 542e13b2937356810bda2c41be83c3b1675e2f2f theStack: ACK 542e13b2937356810bda2c41be83c3b1675e2f2f Tree-SHA512: 0825d30e5c3c364062db3c6cbca4e3c680e6e6d3e259fa70c0c2b2a7020f24a47406a623582040988d5c7745b08649c31110df4c10656aa25f3f27eb35843d99
src/node/
The src/node/ directory contains code that needs to access node state
(state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar
classes).
Code in src/node/ is meant to be segregated from code in
src/wallet/ and src/qt/, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/,
src/wallet/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
This directory is at the moment
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
