   A blockchain network is experiencing a contentious hard fork. A significant portion of the community supports the new chain, while others remain on the old chain. What is the most likely long-term outcome?

   • AThe network will automatically resolve the split based on hash power
   • BThe two chains will eventually merge back into one
   • CBoth chains will continue to exist independently, with their own communities and tokens
   • DThe old chain will eventually die because the new chain has more support

   What is a soft fork in blockchain protocol upgrades?

   • CA change that only affects the user interface and does not alter consensus rules.
   • DA backward-compatible change where new blocks are still accepted by old nodes, but old nodes may not validate all new rules.

   What is the primary technical difference between a hard fork and a soft fork?

   • AA soft fork requires all nodes to upgrade, while a hard fork does not.
   • BA hard fork creates a new token, while a soft fork does not affect the token.
   • CA hard fork is not backward-compatible, while a soft fork is backward-compatible.
   • DA hard fork only changes the user interface, while a soft fork changes the consensus rules.
