When selecting a token technology, you should choose the technology that works best for your project.
Tokenization Benefit
Cost to Transfer
The cost to transfer Ravencoin assets is much cheaper than ERC-721. The cost varies by load on the Ethereum network, and the network is currently at a pretty high load because of the popularity of DeFi lending, trading, etc. The cost of transfer could vary dramatically depending on the at-the-time load on the Ethereum network. If your token needs this DeFi network for its value, then you may want to bear this cost. But if your token is not dependent on the DeFi network which is mostly on Ethereum (currently), then Ravencoin assets transfer for a much lower cost.
Unique Names — Anti-Spoofing
Having a unique name for your token is important for two reasons. First, is to prevent fraud and spoofing using identically named tokens. Just like we all know that IBM on NYSE market is a specific company. Imagine if there were 14 different stocks named IBM, and the only thing that distinguished the company formerly known as International Business Machines was a 40 character hex that looks like this: 0x04abeda201850ac0124161f037efd70c74ddc74d, but there are thirteen others that could look similar. It can lead to fraud as other contracts with a name of IBM masquerade as the real IBM.
Ravencoin takes the unique name to another level by using only uppercase letters, underscore, and . (dot), and then puts in some rules that the . (dot) and the underscore can’t be at the beginning or end of the token name, and you can’t include consecutive underscores, or dots. This is to reduce the incidences of fraudulent tokens. By using i (lowercase) and I (uppercase) in a token, you can make it look similar (with most fonts). For example: IBM looks similar to iBM. The lowercase letters are excluded from token names. Note: Unique Assets (NFTs) have an expanded character set after the # which includes lowercase letters and symbols which can be mapped to serial numbers, and real-life assets.
