The videos show how some decentralized applications (dApps) are used.
Learn how to sign transactions, buy .eth domains, encrypt messages and exchange tokens.
For those who want to learn how to use Ethereum, CriptoNoticias offers this compilation of video tutorials. Through them, it is possible to find out the necessary steps to perform transactions with ethers (ETH) and take advantage of the many functions available on the platform.
The information in these videos is useful for learning how to buy and sell cryptocurrencies, as well as knowing where to manage your public and private keys while taking advantage of smart contract technology. It also shows how to use several decentralized applications (dApps) available online and interact with the Ethereum blockchain.
Buy and sell ETH on LocalEthereum
One of the most widely used ETH exchange platforms is LocalEthereum, a P2P (person-to-person) exchange site that is present in more than 100 countries. On LocalEthereum the exchange takes place through the implementation of smart contractsone of the main features that differentiates Ethereum from other platforms.
These smart contracts set guidelines for the exchange and ensure that funds are released only when both parties reach a mutual agreement. In addition, independent money management is publicly offered, as the private key will be stored only by the user.
In this way, the tutorial explains, step by step, how to register on the portal and how to use the two mechanisms through which you can start transactions on the platform: publishing an ad or buying directly from a seller.
Learn how to use Ethereum with Metamask
Metamask is a wallet that works as an extension or plug-in in Chrome, Brave and Firefox browsers. Provides access to Ethereum network services. With its use, you can make transactions and payments, in addition to signing or executing smart contracts, among other functions.
According to data from the Metamask team, the extension recorded an approximate weekly increase in the number of users of 1.1% with total average of 192,000 active clients monthly. It also works as a traditional wallet where you can manage public and private keys, as well as send and receive, without leaving aside the necessary security mechanisms.
In this sense, the tool has a database of malicious sites that intend to obtain users’ passwords and steal their funds. It makes it easy to run decentralized Ethereum applications in the browser, without the need to run a full node. These apps have an architecture that requires internal payments to perform various activities, be it buying kittens or creating tokens.
The following CriptoNoticias tutorial shows how to use Metamask in its basic form: as a wallet, to create multiple accounts, export a private key and use decentralized applications such as CryptoKitties, Aragon and TokenFactory.
Breed and buy CryptoKitties
Once you are trained to use Metamask, it is possible to use Cryptokitties, one of the most famous dApps to date. This is a game where you can collect “digital kittens” that, depending on their rarity, generation or attributes, have more or less value.
These digital kittens can also be bred and mated to create new cryptokittens, which inherit the characteristics of their predecessors. All these factors affect its final price. So far, the most expensive kitten in the game is Dragon, sold for 600 etheran amount equivalent to more than $172,000 at the time of sale, in September 2018.
Everyone’s a kitten is an Ethereum indivisible token (ERC721). Therefore, to buy, sell or any other operation, the transaction must be done online, which implies a mining cost or fee. The next one tutorial explains in detail the procedure for creating an account on the Cryptokitties portal.
Interacting with the Ethereum blockchain using MyCrypto
MyCrypto It is an interface that allows you to learn how to use Ethereum in a certain way. The goal is for the public to be able to manage funds, whether in ETH or any other token that operates under the network’s smart contracts. Also makes it easy to sign transactions, buy .eth domains, and encrypt messagesexchange tokens (via ShapeShift) or use a MetaMask wallet.
The first version was released to the public in February 2018. In July of the same year, version 1.2.0 was released, with updates to the desktop application. Subsequent updates removed the option to generate a portfolio in the explorer, so To create addresses, you need to download the application. This is intended to offer more security to the user, since information about the initial keys is not uploaded to the Internet.
However, from the portal direct interaction with Metamask, Trezor or Ledger is possible. Although you can use MyCrypto directly from the website, by entering your private keys into the platform, which is not recommended for security reasons.
The CriptoNoticias guide describes how to download an Ethereum wallet from MyCrypto and learns how to manage private keys from the various tools provided by the platform, taking advantage of its main features.
