The May 2021 protocol upgrade was the first to be comprised of [CHIPs](#chips).
|
|
|
|
## CHIPs
|
|
|
|
A CasH Improvement Proposal (CHIP) is a change request for the BitcoinCash protocol.
|
|
CHIPs can be written and published by any member of the BitcoinCash community.
|
|
They are evaluated publicly, giving the authors an opportunity to make any clarifications or adjustments based on feedback from the rest of the community.
|
|
Once there is sufficient support for a CHIP amongst node developers, it is scheduled for release in a future protocol upgrade.
|
|
Changes from multiple CHIPs may be included in a single protocol upgrade.
