-- **No staking minimum** — You can produce blocks and receive block rewards based on your % of the MINA staked on the network. Any user with any amount of MINA can receive these rewards.
-- **No slashing** — the protocol does not need explicit slashing, since the protocol already enforces the required level of correctness.

 ### How large is the Mina Blockchain?
 
 22 KB
 
 ### Given Mina is only 22 KB, where are past transactions stored?
 
-A Mina node can run with an optional flag to make it an archive node to store historic transactions. Archive nodes are useful for anyone running a service such as a block explorer. Still, this historical data is not required to verify the current consensus state of the protocol.
