The Benefits of Using ERC-20 Tokens in Blockchain Applications

ERC20 tokens are a type of cryptocurrency token that adhere to a set of standards established by the Ethereum blockchain. These tokens are created and exchanged on the Ethereum network and have become a popular way for companies and organizations to raise funds for their projects. In this blog post, we’ll explore what ERC20 tokens are, how they work, and why they have become so popular.

Ethereum Simple Smart Contract with Solidity.

In today’s article we will look at an example of a simple Ethereum smart contract developed with Solidity.

We come to the last post in our series on Blockchain and Blockchain development. In today’s article we will look at an example of a simple Ethereum smart contract developed with Solidity.

To do this we will use the erc20 token generator Remix IDE , and we will take advantage of the code to review some of the properties and features that we have been looking at these weeks.

Before proceeding, I recommend you read the previous articles related to Blockchain .

New Smart Contract with Remix

If you enter Remix for the first time, you will see that the platform loads some sample contracts and scripts by default . Inside the “contracts” folder you can edit one of the “.sol” files. “.sol” is the default extension for Solidity files.

You can rename it, for good practice, remove all the code from the file and start writing your own, or add the code from our example:

What does the above code do?

I won’t go into too much detail, because we already know what a Solidity source file looks like, but we will discuss what this code does and compile it to see the interaction.

If you come from the world of JavaScript , you will have noticed that the code is similar, at the level of style and syntax.

Our example contract is a simple input/output contract. What it will do is create and return a greeting.

pragma

As you well recall, after declaring the license of the contract, Solidity requires the version (or versions) on which the contract will run to be declared, using pragma .

state variables

The second thing we do is create state variables. These variables are stored in the blockchain.

As you can see, from the code, Solidity is a strongly typed language, so we erc20 token development had to declare the type of the variable(s). In this case string . We also declare the access modifier as public. If we had declared private it would still be visible on the block chain.

Memory

In the constructor , in addition to the type string , we declare memory. It turns out that in Solidity, variables can be stored in different ways. The three options for storing variables are “ storage ”, “ memory ”, and “ calldata ”. You can learn more about them here .

You will see that “memory” is a type of variable that is in temporary memory and is removed when the function is exited. It is enough for the variables in our example.

View in getGreeting()

In the getGreeting() function we also declare view. If you remember last week’s article about function modifiers , view and pure are two of the most commonly used modifiers. In this case view means that this function will not change any data in the block chain.

abi.encodePacked()

In Solidity we cannot concatenate variables in an easy way, like in JavaScript or PHP with “+” or “.”, respectively. So, to get the greeting “Hello Chiyana”, to concatenate, we use abi.encodePacked (greetingPrefix, name)) as a helper function.

Compile and deploy with Remix

Solidity is a compiled language like Java or C and Remix allows us to compile it. You can do it by clicking on the “Compile 3_Greeting.sol” button.

Then, in the sidebar, access “Deploy & run transactions”. In this case we do not deploy in a real blockchain, but in a test environment (sandbox).

Select the “Remix VM (London)” environment, which was previously called JavaScript VM. In this case we will not have any gas fee involved, so you can also select the account (Account) you want.

Before clicking on “Deploy” you can add an “initialName”, since the constructor receives an initialName .

Then click on Deploy and you will see the result in the Remix console.

Deployed contracts

In Deployed contracts you will see your newly deployed contract. You will also see all the functions of the contract. erc20 development In addition Remix provides you with getters for declared states.

And if you click on “name”, for example, you will see the result that you entered before clicking on “Deploy”.

If you click on “getGreeting”, you will receive the expected greeting:

Set a new name

If you add a new name, for example “Sergio”

and click again on getGreeting you will see that the name of the greeted person has been changed.

conclusion

As you can see, everything has worked correctly. Obviously this was a simple, simple, very basic example, but I think it will allow you to learn and get started, and familiarize yourself with the structure of a smart contract, as well as encourage you in the creation of smart contracts. In real life they will be much more complex and robust.

The success of the merger leaves a green and friendly Ethereum for institutions and corporations

The success of the Ethereum merger, the blockchain that is leading the way to Web3, leaves a green and friendly network for institutions and corporations.

The Merge, the process by which Ethereum updated its software to a more environmentally responsible one, ended today at 8:42 a.m. Spanish time, at block 15537393 . From then on, Ethereum said goodbye to mining and welcomed Proof-of-Stake (PoS) validated transactions through staking.

“The merger will reduce global electricity consumption by 0.2%,” Vitalik Buterin, co-founder of Ethereum and the most visible face of this blockchain, has tweeted. Ethreum 2.0 will consume 99.9% less energy, according to estimates from the Ethereum Foundation.

Ethereum Fusion

This is certainly good news for all corporations and institutions that want to invest in ETH, offer staking services to their clients, or build decentralized applications on the erc20 token development network. Ethereum’s high energy consumption made it incompatible with the Sustainable Development Goals. In fact, it was one of the main problems faced by companies that wanted to bet on Ethereum.

The Swiss bank Seba announced the provision of staking services on ETH 2.0 for institutional clients days before the merger took place. Binance US, the US division of the Binance exchange, also offered staking for ETH with high returns prior to the Merge. Staking is the way to obtain passive returns by leaving your cryptocurrencies on deposit.

Happy melting everyone. This is a great time for the Ethereum ecosystem. Everyone who helped make the merger a reality should be very proud today. However, Buterin announced at the Ethereum Conference in Paris that the merger is only the first in a series of actions that will take place over the next few months. Vitalik said in Paris that with the transition to PoS, Ethereum is only 40% up to date. In fact, for the long-awaited scalability and for the reduction of transaction fees, we will have to wait.

The social network Twitter has been filled with congratulations and congratulations to all those who have collaborated in the development of the new Ethereum. Some, like the artist Beeple, who sold an NFT minted on the Ethereum network for 70 million dollars in March of last year, collects the historical moment of Ethereum in his work The Merge.

Others talk about what an incredible feat it is to transition from a globally used blockchain to PoS without most end users even realizing or having to do anything.

It should be noted that the merger has hardly had an impact on the price of Ethereum. At this time it is trading at $1,586 , with a fall of 1.43% in the last 24 hours, a behavior that has disappointed more than one in the community.

Next update: Shanghai

The next Ethereum upgrade is Shanghai. The update will allow the initial stakers of the Beacon Chain, the PoS chain created in 2020, to withdraw their erc20 token generator and the commissions obtained during these two years. Shanghai will facilitate shard chains, which will serve to provide scalability to Ethereum 2.0. It is estimated that the arrival of Shanghai to the Ethereum 2.0 testnet networks will not be before a year. Meanwhile, companies will continue to push the development of Layer2 solutions, such as Polygon or Arbitrum One.

In the days leading up to the merger, the crypto community has long debated the pros and cons of moving to PoS. For many, it represents a setback in the decentralization of the network. To start up a validator node of those that have the power to add or veto transactions, you have to deposit 32 ETH, about 60,000 euros. If that amount is not available, there are platforms where you can deposit much less money for staking, but they are platforms controlled by private companies. An example is Lido .

The DAO and decentralization

The debate about the decentralization of Ethereum is a matter that goes back a long way. From the moment the hack to The DAO occurred. It happened in June 2016, a year after the launch of Ethereum. The stolen ETH was equivalent to about 60 million dollars on that date. In order to invalidate the transactions, Vitalik proposed to make a fork, something that goes against the basic principle of any public blockchain: its immutability. People opposed to the fork kept the original chain, giving rise to Ethereum Classic (ETC), which these days has appreciated more than 3% and is trading above $38.

Ethereum 2.0 has erc20 development service also found dissidents. A group led by ETH miner Chandler Guo, one of the key people in the Ethereum Classic hard fork, has created EthereumPoW. This is a project that has decided to keep the proof of work to preserve the original network. EthereumPoW plans to fork the network 24 hours after the mainnet merger.

Regarding the debate on the decentralization of Ethereum, the Blockchain Observatory reported yesterday on Ethereum’s increasing dependence on centralized cloud services for its operation. Amazon Web Services alone accommodates more than 53% of all Ethereum nodes currently active in hosting mode. This means a value greater than 30% of the global nodes of the network. The distribution of Ethereum nodes in hosting represents 67.95% of the entire network.
