blockchain is a technique invented in the early days of distributed systems research for making a tamper resistant chain of database update bundles practical Byzantine Fault Tolerance (pBFT) is a technique that uses a 2/3 quorum and a block derived random number to select the leader in a distributed database cluster that can tolerate 1/3rd malicious nodes the Nakamoto consensus is a technique that Satoshi discovered that enabled the lowering of this threshold from 1/3 malicious nodes down to 1/2 malicious nodes, by using a partial hash collision search most shitcoins, except for monero and a few other holdouts, use a variant of pBFT that fallaciously adds "stake" as a "mechanism for security" when in fact it's only a way to limit the number of "authoritative replicas" in a pBFT - because by the cost of messages across the network, as the Cosmos project determined pretty definitively, no more than 100 can participate in such a procedure without dramatically reducing the latency of the system and causing updates to take more than 3 seconds to absorb a new block stake is not a security mechanism, it's a concurrency mutual exclusion lock for 20-100 nodes to get the role of authoritative replica bitcoin solves this problem but can't do better than 1mb/10 minutes and the simple fact is that this means that only one blockchain can be secure with more than 100 nodes in the consensus UTXOs are pseudonymous, the location of the key holder is not revealed by the spender, and anonymity is an absolute, not an achievable, mathematically possible outcome, without weakening some other aspect of the system in general this trade off eliminates the auditability of supply, and no matter what you monero fucks say, your coin does not guarantee supply, there has been multiple inflation bugs and you assholes think that doesn't matter it does. it matters a lot, because the security of a money depends on its hardness, and without hardness, it doesn't matter how private it is, it's scrip.
