What is ERC-20 And What Does It Mean for Ethereum?

Ethereum was launched in 2014 by a teenager . Its vision is to build a world computer that works seamlessly. This includes tokens to fuel it.

Ethereum, the blockchain and cryptocurrency system popularized by Bitcoin was created to allow anyone to create and code any kind of application and then deploy it on a Blockchain. Ethereum uses tokens that can be bought, sold or traded. There are many tokens compatible with Ethereum, but are different from ether . Ether is the second most valuable cryptocurrency in the world by market capitalization, with a price that was flirting at an all-time high as of press time. Ether, the native currency of the Ethereum network, is used for payment fees and rewards to miners.

In this instance, tokens are digital assets which combine multiple values. They can be anything from loyalty points to IOUs or vouchers to physical objects. Tokens, in this case, are smart contracts developed using the Ethereum Blockchain, an open-source blockchain platform which allows developers to create “smart contracts”. ERC-20 is one of the key token standards for Ethereum. It’s a simple cryptocoin built on top of Ethereum that lets developers know how new tokens based upon the standard behave.

ERC-20 Tokens Empower Developers

ERC-20 is a set of standards that all Ethereum Tokens must follow. It was created about 18 months back. The ERC-20 token allows developers to predict accurately how tokens within the Ethereum system will perform. ERC-20 is a powerful tool for developers because projects don’t need to be rewritten every time a token is introduced. They are not designed for compatibility with all tokens. However, in order to create and trade tokens on the Ethereum platform, one has to adhere to a certain set of rules. The ERC-20 rules are very flexible, allowing developers to create a wide variety of tokens with different functionalities. Most developers of tokens are following the ERC-20 guidelines. This means that the majority of Ethereum-based tokens that have been created to date comply with the ERC-20 standard, even though the standard isn’t officially adopted or enforced at this time. OmiseGo, Power Ledger, EOS, and Basic Attention Token are some of the most popular ERC-20 Tokens.

ERC-20 tokens define six functions

ERC-20 is a standard that defines six core functions which other smart contracts in the Ethereum ecosystem can understand. These include transferring tokens and requesting the token balance at an address. These six functions can be found in 99 percent of the ERC20 Tokens currently active. Standard also defines two signals (events) which each token adopts and to which the other tokens will be attuned. The developers agreed that these six functions, and the two events were the minimum viable tokens to standardize communication across the Ethereum Network. Ethereum developers can easily work with smart contracts from external sources by establishing the protocol.

Together, the functions and events allow ethereum to work almost anywhere within the ethereum ecosystem. This means that nearly all wallets which support ether also support ERC-20 compatible tokens. Jaxx, MyEtherWallet.com, and Ethereum Wallet are the most popular wallets for ether.

It is important to remember that ERC-20 was drafted and has not been implemented by the Ethereum community. It seems, however, that momentum has been strong enough to ensure that all new tokens will conform with its rules. The standard is young and there are bound to be some bumps along the way as Ethereum develops. Tokens that are sent to smart contracts will not make money, because the contract of a token only allocates and tracks money.

The money that was associated with the transfer will be “lost” if the contract for the token cannot reply. CoinDesk reports that about $70,000 in tokens have been lost this way. tokens are still a vital part of Ethereum, and will continue to grow in popularity and become more firmly entrenched among the 20 largest cryptocurrencies.
