Perhaps the most appropriate way to view Solana is as a potentially more mainstream Ethereum. Cardano Cardano is a contender for a more environmentally sustainable alternative to Ethereum. Time will tell whether Cardano can unseat Ethereum, or if similar learning curves will occur as more users transact on the Cardano blockchain.

Tezos Coming fast on the scene is Tezos, another smart contract-capable blockchain used to issue new digital assets and create decentralized applications , or dapps. XTZ is the native cryptocurrency of Tezos. Several notable projects have launched on Tezos, including those in the fashion , music, gaming and art industries.

Tezos was one of the first networks to use a proof-of-stake PoS consensus mechanism. It also has unique governance features built in: Participants who stake at least 8, tokens on the network receive voting rights, which allow them to have a say in its governance.

Tezos is also known for its dapp security. Ether is the name for the scarce token that emerges as a result of networked computers running the Ethereum protocol and it is also, like bitcoin: 1 a reward for participation, 2 a currency, and 3 a medium for paying fees. It is a more generalized protocol. Recall that any blockchain technology does the following: it will allow connected computers to reach agreement over shared data.

For Bitcoin, that shared data is a list of bitcoin transactions. This is why the Bitcoin blockchain is commonly referred to as a ledger. We call it a ledger because that word is familiar to non-technical people, but really it is better described as a log or even better a logfile. In computer science, a logfile is just a record of events that occur as a piece of software i. So the Bitcoin protocol generates this logfile, called the Bitcoin blockchain, and it reflects all the events that happen on the Bitcoin network.

The types of events that the Bitcoin protocol allows to be recorded into that logfile are limited and simple—they are the transactions that we discussed earlier, transactions made either as payments between users, fees for use, or as rewards for people that help to make the network and protocol infrastructure work. Some transactions can be a bit more complex. Here, the logfile is recording an event that is a bit more complicated.

The usual event says: Alice sent to Bob. This multi-sig event said: Alice sent to Bob, Carol, and Doug and specified that two of those three people must agree in order to use the funds in the future. In Ethereum, the logfile i. Just like Bitcoin, it can contain a log of transaction-like events where one person sent ether to another, but it can also contain a log of the execution and the results from running any sort of computer program.

So, if I write a computer program like the old Windows game minesweeper, and then append the computer code that powers my game to the Ethereum blockchain, every event that happens in that game clicking a square to reveal either a mine or a free space, number of lives remaining, high scores, etc. Whenever I or someone else on the Ethereum network plays the game, new game-related events are appended to the Ethereum blockchain e. Player One clicked on square A:4 and blew up. Moreover, those game-related events are appended to the log simultaneously with any other events generated by any other computer programs currently running on the Ethereum network.

The Ethereum blockchain really is like a proper computer logfile; it records every event that occurs while the computer is running. The big difference is that it is actually logging events redundantly on every one of the computers connected to the Ethereum network. If it was free for anyone to run any type of application on the Ethereum Virtual Machine, the system would quickly become overloaded.

To stop this from happening, the Ethereum protocol makes every computation indeed every step within a computation require a small fee that goes to the particular computer on the network that recorded the official version of the log for that period. This is similar to fees in Bitcoin, where any fees attached to a bitcoin transaction go to the miner who mined the block that included the transaction.

How do you pay the fees? With ether, of course.

Before we can import an account to our MetaMask, we need to connect it to our local blockchain. Leave the rest blank and click save. Since the imported network is empty, we must now add one of the play accounts provided by our Ganache workspace. To do this, click the three vertical dots in the top-right part of your MetaMask, which will display a drop-down menu, as you can see in the image below.

To complete the renaming process, click the tick and then the cross. Again, as our aim is to learn how to build dApps on Ethereum, we also want to be able to test some transactions between various accounts. If you went with the same amount as we did, there should now be You can see the latter in your MetaMask and also inside your Ganache workspace.

Moreover, you can also try sending some ETH from one of the two accounts imported in MetaMask to any other account within your Ganache workspace using the steps above just replace the address accordingly. How to Build dApps on Ethereum — Using Testnets When we were importing our local blockchain into MetaMask, you probably noticed that there were several public testnets offered. These testnets are Ropsten, Kovan, Rinkeby, and Goerly.

Therefore, we want to show you how to add loads of funds to your testnet wallet for free. The first one is supposed to drop 0. Moreover, keep in mind that transactions on the Ropsten Testnet need to be mined, so it takes slightly longer for them to go through compared to using a local network. If you decide to use other testnets, make sure to use your favorite search engine to find free ETH faucets to fund your account on those testnets.

We believe that the best way to learn is to build an example project. In case you are a total beginner, this may sound rather complicated; however, this process will feel like a breeze, thanks to Moralis. So, are you ready to roll up your sleeves and tackle this interesting task? Once on the website, download examples and source code. These template files will serve as a great starting point. Complete the steps by naming your server, selecting your region, mainnet, and all chains.

First, we need to make several tweaks to the initial file obtained from Bootstrap. To follow along with one of our expert developers as he performs a code cleanup, make use of the video below, starting at Furthermore, we want to ensure that only logged-in users have access to the dashboard, while those not logged in are redirected to the login page.

Keep in mind that these snippets of code need to be adjusted to match your particular project. Moreover, specific JavaScript code must be added to achieve our goal. Get Transactions When it comes to getting transactions, Moralis offers two options. The few lines of code above take care of all the heavy lifting on the backend that would require hundreds of lines of code without the use of Moralis.

Pretty awesome, right? To further polish the way our example dApp displays transactions, some JavaScript coding is required. Once you sign up and log in to your account, you will see a navigation bar to the left of the Moralis interface: However, we will leave these for now and explore some of your options in the third step of this tutorial. Step 2: Cloning the GitHub Repository In this part of the tutorial, we will show you how to clone the GitHub repository which we linked to in the introduction onto your local device.

However, you are free to use any IDE integrated development environment , but the process might differ somewhat on occasion. Nonetheless, the process will not vary significantly, and you will most likely be able to follow along as we go — even if you are not using VSC.

The first thing you need to do is open the GitHub repository using the link from the introduction. Next up, you can proceed by creating a new folder. With the folder at your disposal, you need to open a new terminal. This section will go through each and show you the necessary configurations.

This is the chain ID for Ethereum, and as you are looking to build an Ethereum dapp, you can leave this as is. This is where your Moralis account enters the picture, as this is from where you fetch the key. As such, you can navigate back to the Moralis admin panel. It can remain the same as you currently are in the development process. This allows you to test the dapp in a safe environment.
