You look at Fortune 500 companies, companies that are profitable and end up paying zero in taxes. On small businesses: Small business owners pay and pay and pay on taxes because the loopholes aren't as available to them.
The lottery is then seeded using the block header hash of the tip. If you are the stake winner, you quickly create a sidechain block (paying its fees to yourself) and its header, then sign the sidechain block header and publish it as quickly as possible to all miners, before another mainchain miner gets the next mainchain block.
Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, and services. Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. When sending bitcoins, users can pay an optional transaction fee to the miners. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins.

블록체인 포크 중에는 다수의 블록이 같은 높이를 가질 수 있다. 그래서 블록은 주로 고유한 식별자로 블록헤더의 해쉬(the hash of their header)을 사용한다(종종 바이트 순서를 거꾸로 한 16진수(the byte order reversed, and in hexadecimal)로 표시된다). 따라서 블록 높이는 고유한 식별자로 사용될 수 없다.
각 블록헤더는 반드시 타겟 값(target threshold)보다 작은 해쉬를 가져야 하고, 각 블록은 이전에 생성된 블록과 연결되어(linked to the block that preceded it) 있다. 이 때문에 수정된 블록(a modified block)을 전파하는 행위는 많은 해시 파워(hashing power)를 요구한다. 원본 블록이 생성된 시간과 현재 사이에 전체 비트코인 네트워크가 이미 소모되었기 때문이다. 트랜잭션 기록(transaction history)에 손을 대는 행위, 그리고 이를 다시 전체 네트워크에 전파하는 건, 전체 네트워크 해시 파워(hashing power)의 51%를 가지고 있지 않으면 불가능하다 (물론 50% 보다 적은 해시 파워를 가지고도 충분히 이와 같은 행위를 하는 것이 가능하긴 하다).

We should also consider what mainchain miners can do to attack or otherwise damage the sidechains dependent upon the mainchain, regardless of what reasons we may imagine they have to attack or crypto not attack. But we should note that while sidechain mainstaking is a virtual mainchain mining, the virtualization itself is dependent on the mainchain operation.
In effect, nothing-at-stake is avoided by publishing checkpoints on the mainchain, and using mainchain consensus to commit to the checkpoints. Stake-grinding is avoided by reusing the mainblock header hash as the lottery seed for the next mainblock; any stake-grinding attempt needs to also target the current difficulty on the mainchain, increasing the effective difficulty a stake-grinder needs to target.
Despite the fourfold increase in the number of merchants accepting bitcoin
in 2014, the cryptocurrency did not have much momentum in retail transactions. Criminal activities are primarily centered around darknet markets and theft, though officials in countries such as the United States also recognize that bitcoin
can provide legitimate financial services. Instead of 2–3% typically imposed by credit card processors, merchants accepting bitcoins often pay fees in the range from 0% to less than 2%. The European Banking Authority and other sources:11 have warned that bitcoin users are not protected by refund rights or chargebacks. The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and media. In February 2015, the number of merchants accepting bitcoin
for products and services passed 100,000.
