Price Analysis April 6: BTC, ETH, XRP, BCH, BSV, LTC, EOS, BNB, XTZ, LEO

During a crisis, the first thing panic-stricken investors do is to sell almost every asset class they perceive is likely to go down.

We have seen both of these phases play out for cryptocurrencies.The sharp selloff on March 12 was a good example of panic and the sharp correction was quickly followed by a phase of cherry-picking by long-term investors. Since bottoming out on March 13, most major cryptocurrencies have rebounded

Smart Contracts: Don’t Reinvent the Wheel

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:

Ethereum DApps: How to Listen for Events

Using the instance we created in step 2, we can subscribe to listen out for any events that it emits.Figure 4: Subscribe to ‘MyEvent’As stated earlier, the event we want to listen for is called MyEvent, and figure 4 shows us how. Our myContract instance has an accessor called events from which we can target MyEvent. This is an asynchronous function that returns a promise, and it’s called every time MyEvent is emitted.Line 3 defines what happens once data has been returned from the promise. Here we’re simply logging the

Staking, Consensus and the Pursuit of Decentralization

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
