How mining works for a new born cryptocurrency

What I have learnt that mining is breaking a block which contains transactions using hashing algorithm (Sorry if this is wrong please do correct me). Now my question is how mining will work for a new born cryptocurrency or for a cryptocurrency using which no transactions are being done? Since no transactions means no new blocks? TIA

What is the fraction of the Bitcoin mining-power that might be engaged in Selfish-Mining?

Is there an estimate for the fraction of miners engaged in Selfish Mining within the BTC network? In light of the publication The Impact of Selfish Mining on Bitcoin Network Performance (2021), selfish miners not only gain an extra (unfair) share of the block rewards but also increase the chance of forking the network and implementing double-spending attacks. To accomplish that, a group of mining pools holding ~25% of the mining power would be enough to attack the network. I believe this should get more attention from the community since it represents a significant cut in threshold-security from the famous…

Why implement *Wallet* at library level?

Using bitcoin-qt, and we need to create Wallet to handle our account (Private + Public Keys). But I really don't know why we are forcing this to everyone at library level. I can't find a simple way to handle multiple wallets with one single instance of bitcoin-qt. Can I have multiple addresses from different users added to the same wallet? My spider sense tell me NO. It is like we are sharing the same wallet with stranger in real life.

Bitcoin Core Wallet doesn’t accept my passphrase

I am using Bitcoin Core Wallet .21 and have encrypted my wallet. When I try to send some coins it asks for the passphrase, which it says is incorrect. I have only ever used one of two passphrases and I have copied and pasted these each time using notepad (upper and lower cases), but it rejects my passphrase every time. There is nothing wrong with my passphrase, I know my passphrase is correct. Are there any circumstances under which the wallet would behave like this? I have used old backup files of my wallet, but get the same message. Could…

Found Bitcoin Core Wallet with unconfirmed Transactions, anything to salvage?

I am currently looking through old .dat files and found a wallet with two "Received with" transactions that are unconfirmed. When I enter the address from the Label on blockchain.info the address shows a balance of 0 and 0 transactions. Does that mean, that the transactions are invalid, and that I have to find the origin address to figure out a remaining balance, or is there anything other that I can do? Bitcoin Core is only synced to 2017 yet.

Why universities and colleges don’t accept Dogecoin donation?

I just tried to contact the top universities in the USA and other countries. i also contacted the charity organizations such as Red cross and united way, etc. but no response at all. seems they don't care the donation of crypto currency like Dogecoin as the price is too low? The fact is that most of us are ordinary people who can't donate millions like those billionaires. but we do can donate 10k dogecoin or 1 million dogecoin instead. we also wanna show our support to the chariting causes to make the world better. Yes, they may want BTC as…
