what about abbreviating the million? I read that 'MM' is most common than 'm' or 'mil' so, use 1MM XEC instead of 1,000,000 seems to nicely avoid unnecessary zeroes

looks like something broke the tests, back to your queue

tests broke

• extension/src/components/App.js still has fbt imports and tags
• .gitignore still has an fbt related file section
• test plan doesn't test all changes

tested ok

use uint32_t instead and use default std::memory_order_seq_cst for atomic increment

synchronize static variable, remove static uint256 hashPrevBlock which is now dead code

... do it consistently

use a smaller integer

ensure nExtraNonce is changed in exactly one place, fix expected block hashes in rpc_dumptxoutset

forgot the most important line

with the -ecash prefix, this seems less relevant. abandoning for now.

remove now unnecessary DEFAULT_XEC constant

undid irrelevant change in qt/test/test_main.cpp

moved some of the changes to D9672

this needs changing now
