◆ ApplyHash() [1/3]

static void kernel::ApplyHash ( HashWriter ss,
const uint256 hash,
const std::map< uint32_t, Coin > &  outputs 
)
static

Warning: be very careful when changing this! assumeutxo and UTXO snapshot validation commitments are reliant on the hash constructed by this function.

If the construction of this hash is changed, it will invalidate existing UTXO snapshots. This will not result in any kind of consensus failure, but it will force clients that were expecting to make use of assumeutxo to do traditional IBD instead.

It is also possible, though very unlikely, that a change in this construction could cause a previously invalid (and potentially malicious) UTXO snapshot to be considered valid.

◆ g_context

Context * kernel::g_context

Global pointer to kernel::Context for legacy code.

New code should avoid using this, and require state it needs to be passed to it directly.

Having this pointer is useful because it allows state be moved out of global variables into the kernel::Context struct before all global references to that state are removed. This allows the global references to be removed incrementally, instead of all at once.
