 Program execution results are the manipulation that causes the rewrite of variables of a class. Developers can deploy self-made program on Ethereum, execute it at P2P network on Ethereum, and record the execution result by Merkle tree. Ethereum is also thought to be an autonomous runtime.

 Since written programs are freely executed on Ethereum, there is no limit for its usage.

Token is a standardized program for "the program as currency", which is generally called as crypto currency or crypto assets.

 ### Minting NFTs
 
-When you stake DEV in Property Tokens, you automatically get an NFT. The NFT is called sTokens in Dev Protocol. In technically, sTokens store the status of the staking position, but its cover image can be freely changed for each Property Tokens, so you can enjoy the artistry too. sTokens cover images can be changed statically or dynamically, and dynamic sTokens (=dynamic NFTs) can customize their output according to different conditions.

 All sTokens indicate some staking position, they can be used as keys for any token-gating. For example, you can permit a community channel exclusively to users who have 100 or more DEVs staked in your Property Tokens, or sell exclusive items.
