            Internal Server Error on FindItems for Public Folders

            When you see an error like that after adding that particular line, then the syntax error is on that line. With that being said, you cannot have variable names in JavaScript start with a number. But, you can still make it work by accessing the object like a map rather than a member variable, by using bracket instead of dot notation syntax:

            All atomic operations on a specific atomic object are guaranteed to be visible to each thread in the same so-called modification order of the object, that is they always appear consistently. (Otherwise the whole idea of atomics would not make much sense to me, anyhow.)

            On the other hand, when exactly individual threads perceive the changes is entirely up to the "implementation", that is the compiler and/or runtime. Because architectures are much different in what you could expect, here, this is a what the C standard calls a "quality of implementation" issue, that is you'd have to complain to your compiler writer or chip constructor if you think that they are too slow on this, e.g.

            The problem with your original code is that the builtin any function is meant to take a sequence of Boolean values and return True if any of them are True, but you passed it a list of exchanges.

            Instead, you should check whether each exchange is present in the data, and use any to figure out if this was True for one or more exchanges:

            Most of this is not related to the token code and is an economics topic. Which is offtopic here at StackOverflow, so I'm just going to briefly say something that is only partially correct: As long as there's enough buyers and sellers willing to buy/sell the token for the price of gold, the token is going to have a price of gold.

            However, you can define functions in your contract that control its total supply, which affects the price (sometimes affects the price - economics again).

            From where crypto on-chain data are coming from?

            I am pretty new to the topic and I would like to understand or if you could re-direct me to the proper source of knowledge about on-chain data, where are they coming from?

            How such websites as Glassnode or CryptoQuant are able to deliver such a sophisticated charts about wallets, transactions, exchanges, market indicators etc. ?

            Are all of those data publicly available on the blockchain and those companies are running kind of "queries" to get such data?

            I am just wondering how it works under the hood, to be able to get such on-chain data?

            As the name "on-chain analysis" suggests, the base data are collected from blockchains. Most analytics companies combine the blockchain data with their own knowledge. Sometimes it's combined with public data that are just complicated to filter out. And sometimes they're using non-public data that they got from exchanges and other sources (possibly for this specific purpose of combining with other data and reselling the combined product, but not reselling the raw data).

            Example: Exchange X has

            • cold wallets A, B and C - All of this is published by the exchange.
            • hot wallets D, E, F and G - Part of this is public knowledge, part is info from the exchange directly to the analytics company.
            • user deposit wallets H, I, J, K, L, ... - The exchange told the analytics company and keeps them updated on new and removed deposit addresses (in exchange for some fee). Part of the agreement might be that the analytics company can't share these addresses, just the combined amount.

            The analytics company can watch transactions coming from/to these wallets (this is the public blockchain data) and make a sum of how much crypto has arrived to or left from the exchange.

            as you discovered, both the colors and series options color the series the same.

            you must use the style role to color bars in the same series different colors.

            the style role column must follow the series column it should be applied to.

            you have included the style role in your example, but is included only for one series, and it is blank.
