Now you can listen to 15 crypto podcasts about blockchain and the crypto space on it. If you are too lazy to read further, go to the platform: you will have enough material for you.
 
Off the Chain
Format: Interview
Frequency: One episode per week
The host of this crypto podcast is none other than Anthony Pompliano, co-founder of Morgan Creek Digital and one of the most famous people in the crypto space. He probably has the most popular podcast about cryptocurrencies (crypto assets).

Podcast host Laura Shin is a former Forbes editor and one of the first crypto journalists. She hosts two cryptocurrency podcasts. Unchained is a weekly hour-long crypto podcast with invited experts and a deep dive into the topic. The interview topics go beyond the crypto world and relate to the impact of technology on our lives: from financial services to healthcare and the Internet of Things. Unconfirmed is a weekly 20-minute podcast discussing the main information guides and insiders of the week in the crypto space. Unconfirmed is one of the best crypto podcasts for those who prefer short and digestible content rather than long conversations.

Bad Crypto Podcast
Format: Cryptocurrency news, reviews, interviews
Frequency: Three episodes per week
The podcast has been out since the middle of 2017. It is hosted by digital marketers Joel Comm and Travis Wright. Guys talk about cryptography carelessly, cheerfully, wittily, banteringly, but to the point. In-depth technical analysis (bitcoin and blockchain tech), a cascade of jargon, and trading terms will not be heard here. But if you want an easy but useful conversation about the crypt on the way to work or in the gym— it is a great podcast in the crypto space. Comm and Wright also run a blog in crypto Twitter.
 
Crypto101
Format: Cryptocurrency news, reviews, interviews
Frequency: Two episodes per week
Crypto101 is one of the leaders in our selection. It has a 4.5 rating with more than 500 reviews on the Apple Podcast. Presenters Aaron “PizzaMind” Malone and Bryce Paul. Malone is a data analysis expert, co-founder, and system architect at mining company A-B Engineering, author of two books, and Paul is a prominent crypto speaker. The presenters try to educate newbies about the advantages of blockchain and keep them up to date with the latest industry crypto news. They pay a lot of attention to altcoins. If you play chess, you can challenge Bryce Paul on chess.com – his nickname is stratocaster4 (yep, he is also a guitar fan).

What Bitcoin Did

Crypto Discussion / How to create ERC-20 token?

« on: December 23, 2021, 10:08:04 PM »

15 Minutes Guide to Creating an ERC20 Token Based on Ethereum

Ethereum ERC-20 tokens are coins of third-party projects that work on the Ethereum blockchain. They are based on the ether network, use its power to conduct transactions, support its addresses and wallets, but at the same time have their own tickers, issue, rate and value. For example, although EOS is an ERC20 token, it boasts a capitalization of $ 11.5 billion, which is more than the absolute majority of independent cryptocurrencies that are mined by mining.



Most often, ERC-20 tokens are issued during the ICO in order to attract funding from investors (the token generation process is called TGE, from Token Generation Event). Projects issue a certain number of coins and sell them to everyone for bitcoins or ethers. It turns out something like startup shares or certificates confirming ownership of the asset. In addition, tokens can also act as an internal currency within the application system, individual stake coins, bonuses in the loyalty program, etc.

It should be understood that although ERC-20 tokens work on the ether blockchain, this does not mean that they will necessarily go on the stock exchange and increase in price by thousands of percent. Yes, of course, there are very promising projects with great potential and a great team that have a great future and can shoot. But there are also absolute shitcoins that are created to collect millions from investors and disappear into the night. Therefore, you need to be careful.

The Technical Side of the ERC20 Token Issue
In fact, ERC-20 tokens are smart contracts on the Ethereum blockchain that comply with a single unified standard and work within the framework of the Ethereum team. Accordingly, ERC-20 is a single standard that includes a set of basic rules for the contract and ensures its compatibility with the network. ERC stands for “Ethereum Request for Comments”, and 20 is the offer number.
The unified standard ERC-20 was first formulated in 2015. Before its existence, all smart contracts were quite heterogeneous, which could cause compatibility problems between them, and wallets would have to significantly add code for each specific token. In total, the set of rules includes 6 mandatory parameters and 3 more recommended ones:
 

• Two functions related to the issue of ERC20 tokens — totalSupply (the total number of coins and the inability to create new ones when their maximum number is reached) + balanceOf (the initial number of coins that belong to the creators);
• Two functions for making transactions between users — transfer + transferFrom;
• Two functions for transaction verification — approve and allow.

Despite the fact that all smart contracts correspond to the same protocol, they assume different functionality, and of course, they have completely different vulnerabilities. Only the laziest ones have not heard about leaks in ether contracts. Even one story with a DAO contract or a Parity wallet is worth considering. From a more recent past, you might note the recently found batchOverflow and ProxyOverFlow bugs. Several exchanges even suspended accepting deposits and withdrawing ERC-20 tokens due to the fact that hackers can generate huge amounts of coins, transfer them to regular addresses and manipulate prices.

Making an ERC20 Token
Creating an ERC20 token and conducting an ICO is definitely not a rocket science task.
Preparing for the ICO, you should understand that the ICO is a pure marketing event. If you think that you will need a staff of programmers to conduct it, it’s a serious mistake. You’ll need marketing staff, as well as a normal amount of currency, to attract public attention. Yes, there are ICOs that happened without serious investments (due to their idea/experience/connections), but let’s not flatter ourselves with hopes and deceit — to collect a million dollars, you will have to invest thousands of dollars in ICO.
There are many ways to create your token. The simplest and the most popular are:
 

• Go to Waves/Cryptonotestarter (or analogues) and release your coin in 1 minute right in the interface.
• Solidity/Pyethereum (Ethereum-based token). Using the knowledge and/or the ERC20 smart coin writing standard (in fact, the source code of the coin with many blackjack variants) to sign a contract.To launch your token, you need to take the source code of the ERC20 token, change a couple of lines and upload the contract to the network by one of the clients (of.client Ethereum / Metamask / etc).

To Issue an ERC20 Standard Token, You Need:
Step 1

• choose a name, for example Best Coin
• choose a symbol, let’s make it BEC
• choose the number of ethereum based tokens, it is unchanged, for example 10,000
• choose whether the tokens will be divided, if so, how many decimal places will be the maximum

If you trust the community, you can use the utilities — this or others. The problem with such services is that they do not provide source code, only byte code. Therefore, there is no confidence in their purity. But most often, such things are written by guys with a name, so you can still trust it.
 
Step 2
Deploy the Token
Enter this data into the smart contract available by the link. Download both .sol files. Go to the remix editor. Download both files.



Files are loaded with the Load(Open) button. Select both files.
Open NewToken.sol, put the necessary values in <brackets> instead of variables:
 

• totalSupply — total number of tokens
• name — the full name of the token
• decimal — the number of zacks after the decimal point. The fact is that in contracts, everything is stored only in integers. Therefore, you should specify the number of characters if you want to be able to credit a non-integer number of tokens.
• symbol — a symbol for exchanges
• buy ads
• unplug

It should turn out something like this:
 


Save it. It remains to upload the contract to the network. For example, install it in the Ropsten test net. Any client will be required for the deployment. Let’s use MetaMask — it does not know how to compile smart contracts on Solidity, so we will compile first.



In the right part of the remix editor, open the compile tab. By default, the contract is compiled automatically. By selecting your contract in select and clicking Details, you can view the bytecode and other information.
To deploy, click Run, select Injected Web3, select the Account that we will deploy (it should load automatically if you have MetaMask installed in the browser). Enter the necessary information in the fields (gas, value), click Create.
 


MetaMask picks up the action from the page.
Click Submit. Your contract is sealed. The dispatch is confirmed in MetaMask by an icon with a document (it leads to the transaction page) and the inscription “Contract published”.
 


A sealed smart contract is a token.
 
Step 3
Token Operations
Ethereum based token transactions require two wallets — the one that already has them (by default, the contract creator, the ERC20 standard) and the one that needs to transfer them.
Perform operations with our token (transfer it, for example). We can either on the etherscan contract page (link in MetaMask) or on the remix page.
 

 
Blue here — read operations, pink — write operations.
To transfer ERC-20 tokens, enter the recipient’s address and quantity. After that (and entering data into the blockchain, of course), you can check your balance or the balance of the recipient of the tokens with the operation balanceOf.
Done!
