How to select a crypto currency wallet
As with fast synchronization, if you're too far behind, the peer node may not be willing to give you the data you need. The pivoting mechanism is the key to solving this problem. pivoting in Beam synchronization The mechanism is like in fast sync, where your node selects a series of blocks to skip and a new one near the top of the chain Block block header, then Beam syncing starts again, the node doesn't completely start syncing from scratch, it still has the All data from the last sync. Whether you're using Beam sync or fast sync, there's a cost to using the switch mechanism, and switching The mechanism means that more data needs to be downloaded, and some of that data will also be blocks whose execution your node has not personally verified. The good news is that if you're not more than 30 minutes behind, the Beam sync method doesn't need to activate the toggle mechanism, instead! You have to switch several times when using the quick sync method. Well, let's see what it looks like in real life.
That statement should be the key to the solution. Going back to the Bitcoin paper, because a particular time period is used to generate z blocks, that time period is divided into z slices of time, each time The probability of the attacker in the slice acquiring the next block is q/p, so according to the above this constant (lamda) is time slice The product of the quantity and the probability of time occurrence within each time slice, i.e., lamda = z(q/p)
The FCA is eroding the pseudo-anonymity of many cryptocurrencies (e.g. Bitcoin) and many anonymous coins (e.g. Monero)

However, the wallet provider does not have access to the user's private key, and therefore does not have the ability to misappropriate the user's funds. As a result, the wallet provider places the burden of keeping the user's private key back on the user.
