Binance had paused withdrawal of Bitcoin, the world’s largest cryptocurrency, for more than an hour. Of course, node software can (and has been) optimized, to eke more computation (and hence transactional validation) out of the same number of bit flips. Binance’s success isn’t surprising, as its founder, Chanpeng Zhao, is known for creating Fusion Systems, a high-frequency trading software. With the right trading tools at disposal, traders can make great returns. However, the wallet owners need to be vigilant in case of trading parties that entice with unreasonable high returns and tend to trap the owner into giving away their private keys or other such information. They make it costly for information to be stored on the blockchain, thereby disincentivizing spam and DDoS attacks that have historically plagued zero-/low-fee networks, like Nano, EOS and XRP. But still, running an Ethereum node should be doable on high-end consumer hardware if users discard some historical information after validating it, youtu.be a technique called “pruning.” It is not out of the reach of a somewhat technical individual with a modest budget. Congestion exists in a blockchain context because the basic security model of blockchains requires that end users can independently audit and verify the transactional history from the very first block should they choose to, and there’s a limit to the quantity of data that can be audited per unit time.
If you do all of these things, and your blockchain is popular, fees will organically emerge, as they did in Bitcoin and Ethereum. These trading interfaces give users access to data that will inform their order strategy. Binance gives its users the option to buy cryptocurrency with their credit/debit card. The dark web allows users to buy and sell illegal goods without being tracked by using the Tor Browser and make illicit purchases in Bitcoin or other cryptocurrencies. The design philosophy of both Bitcoin and Ethereum (at least in its current form – founder Vitalik Buterin has more ambitious plans which deviate from this idea) stresses the importance of an individual being able to run a current copy of the ledger. But this bounty exists due to the issuance of new coins as fees are de minimis (in Bitcoin at least). Bitcoin’s design philosophy aims to permit anyone with at least a weak internet connection and consumer-grade hardware to perform a full audit of the transaction log. Bitcoin’s protocol makes available a theoretical maximum of 4 MB of new block space every 10 minutes – in practice, this hovers around 1.2 MB at the current weekly average. In Bitcoin’s case, this fee-based revenue will pay for security once issuance trails off.
Conversely, at some point next year, Ethereum will move to a proof-of-stake model, at which point it will stop consuming meaningful amounts of energy. But this is a PoW network, and its miners absolutely consume energy. As per a very famous investor, during the Gold Rush, several miners have lost money. Most crucially, fees promote a competitive environment among miners which in turn makes it prohibitively expensive for single parties to successfully attack a network. The reason that Solana, for instance, has low fees, is simply because the designers of that network were happy to adopt a different security model from Bitcoin or Ethereum. Mining starts with incoming Bitcoin transactions, which are continuously broadcast to every computer on the network. To make a rough corporate analogy, fees are “revenue” and issued supply is “equity.” Many firms do finance their operations by continually issuing stock, but shareholders generally prefer not to get endlessly diluted. Waiting to purchase your favorite domain is a financial mistake, or, even worse, you may never be able to get it at all, at any price, if someone buys it first.
If demand exceeds supply, a queue emerges, and the highest bidders get priority access to block space. One way is to create an auction in which eager transactors can pay up for priority inclusion in a block. Depending on the severity of these events, a transaction that was once in a block might be permanently removed from the blockchain. Having material fees is extremely healthy for a public blockchain system: it eliminates the spam problem by making it costly to insert junk data, and it constitutes “protocol revenue” that can be directed to a number of causes. You could also redirect fees to finance various public goods like paying Core developers. They take in dirty money as “payment” for supposed goods or services but actually provide no goods or services; they simply create the appearance of legitimate transactions through fake invoices and balance sheets. Money launderers often use sophisticated techniques to create complex chains of crypto transfers that cover their tracks, the FATF and the International Monetary Fund have said. Morgan pleaded guilty to one count of money laundering conspiracy and one count of conspiracy to defraud the United States, each of which carries a maximum sentence of five years in prison.
