Kontext: Präsentation darüber, wie man eine Kryptowährung erstellen kann, die auf der XXX-Blockchain basiert


• In this demo I assume the ExampleCoin utility will be used by very few users (just me) to manage very few accounts, so there’s a few scalability issues: using a csv rather than a database, for example, or trying to hold everyone’s running balance in memory as the results are tabulated.
• Currently the utility starts from scratch every time you run it, and overwrites the output file entirely. One could change it to use a preexisting output, and just scan along the chain from where it left off.
• Since the utility needs to read every single block in a potentially large range of blocks, it needs to be run on a machine with an XXX archival node or relay, so that the blocks that the utility needs are never pruned.
• I have not audited any of this code for correctness or security, as it’s a quick toy demonstration. I wonder if someone can steal my precious ExampleCoin?
• I mentioned briefly that this functionality is sort of analogous to ***named fungible tokens***, similar (kind of) to ERC-20. With some changes, one could probably tweak things to work like nonfungible tokens (NFTs).
• Code and data can be one and the same thing, can’t it? Can you picture a system that puts code on the chain as encoded data, executes it, and puts new code on the chain in response? A self-amending program?
