SafeMathIn most modern programming languages, safety in arithmetic operations is accounted for, so little thought goes into their implementation. However, in Solidity, overflows and underflows present a security risk.SafeMath is a library that ensures safe arithmetic operations by reverting the transaction if the bounds of an integer data type are exceeded.SafeMath example.The using statement indicates to the compiler that the contract is using functions defined in SafeMath for uint operations. Instead of using arithmetic operators (+, -, *, /, %), use the functions add(), sub(), mul(), div(), and mod(). Source:

Oh, the wonders of decentralized consensus — that dream of permissionless blockchains to be censorship-resistant, trustless, collaborative and egalitarian for a potentially global community of users. While lofty in ideals, consensus is foundational for each crypto network, which must agree upon that most basic question of who decides what on the network.Decentralized consensus in the form of a proof-of-work mechanism was at the core of Satoshi Nakamoto’s innovation when creating Bitcoin — all additional protocol elements stem from PoW’s ability to reach consensus regarding the digital ledger through the computational work

Yes, that’s the question we are asking today. Is blockchain technology necessary? The answer is tricky. To arrive at the conclusion takes an unbiased perspective. Bankers and people in the stock market will tell you that it’s the epitome of evil. Blockchain engineers and enthusiasts will tell you it’s the future of the world. The government, as usual, will be indecisive.Both are overly eager in their opinions, and both are unfortunately wrong. Blockchain is wonderful and revolutionary, no doubt there.
