So layoffs are bad, but not doing layoffs is bad too?

A blockchain is only as secure as the amount of work (= processing power) that goes into it. Anyone with 51% of the processing power invested in a blockchain can attack it and essentially steal from other people. For cryptocurrencies it’s a problem that solves itself, because every person that possesses some of the cryptocurrency is incentivized to mine to keep it secure (and to earn some at the same time). The more your cryptocurrency is valuable, the more people will want to mine it and the more secure it will be.
For anything other than cryptocurrencies, you can’t incentivize a huge number of people to commit computing power to secure your blockchain. So you have to protect it some other way, for example only allowing you and some trusted people to write on it. But then it doesn’t really need to be a blockchain anymore, just a write-only database (which will perform better and occupy less space).
If it requires no work to generate a block at the end of your blockchain, any attacker can generate malicious ones.
They’ll probably cost $3,000 (if not more) but they will sell truckloads of them
