The ERC-20 stands for Ethereum Request For Comments, and the number 20 denotes the unique numerical ID used to differentiate the standard from others.
ERC-tokens are digital assets developed, issued, and used in the same way as Bitcoin.
ERC-20 is a collection of guidelines that helps developers simplify and enhance the process of developing a standard Ethereum-based token.
ERC-20 tokens work similarly to ordinary cryptocurrency, but their ideas are distinct. Indeed, the terms cryptocurrency and tokens have distinct meanings and should not be used interchangeably.
To begin with, cryptocurrency is a type of digital asset that is encrypted using encryption. This implies that these coins run on their own blockchains, and the ledgers are distributed across decentralized blockchains.
Meanwhile, Tokens are a type of utility that runs on top of a blockchain. ERC-20 tokens and several other equivalents, such as ERC-223, ERC-721, are among the most popular.
ERC-20 tokens differ from normal crypto in that they rely fully on the Ethereum blockchain rather than having their own blockchain. As a result, there is a gas price to complete a transaction. And a miner utilizes these fees to accomplish network transactions. And the gas charge varies according to network activity. Finally, the more the gas taxes, the more crowded the network.
Fabian Vogelsteller, a prominent player in the blockchain sector with a background in web development, introduced ERC-20, the technical standard underlying smart contracts implementing the currency on the Ethereum blockchain, in 2015.
A smart contract is a piece of code that is run in response to a request from a user or another program. Smart contracts are also in charge of conducting transactions, validating fees, and keeping track of the balances of each token’s holders.
These contracts often have a unique name, supply, and behaviour. However, as long as the core ERC-20 criteria are followed, they are all ERC-20 compatible.
Because ERC-20 tokens are based on smart contracts, their functionality varies. It can be used as money, reputation points on an online platform, lottery tickets, a financial asset such as a corporate share, or evidence of ownership.
The following are some of the properties of ERC-20 tokens:
ERC-20 tokens are commonly purchased, sold, swapped, or traded on cryptocurrency exchanges. They may be stored in any Ethereum-compatible wallet, such as MetaMask and MyEtherWallet, as well as a paper wallet, wallet software, or even a hardware wallet, such as the Trezor or Ledger Nano S.
On the Ethereum blockchain, there are several token specifications. ERC-20 tokens are among the most widely used. On Ethereum’s main network, more than 200,000 ERC-20-compatible tokens exist, according to Etherscan. Many of the top digital currencies by market cap are used for diverse reasons.
When Ethereum introduces sharding and changes to the Proof-of-Stake consensus mechanism in the ETH 2.0 Upgrade, we may anticipate the number of projects based on the ERC-20 standard to rise tremendously. Furthermore, ETH 2.0 addresses transaction concerns by allowing users to make ERC-20 token transfers virtually instantly and at a lower cost.
ERC-20 may continue to be one of the most popular standards used by many developers throughout the world. However, it is not without flaws. Many solutions try to solve technical issues with the standard. However, most of them continue to be short and deceptive hacks that do not provide a comprehensive explanation. As a result, while evaluating an ERC-20 initiative, investors should keep this in mind.
