ARC-20 is a token normal that makes it potential to create fungible tokens that may be held and transferred on the Bitcoin blockchain. ARC-20 normal tokens are issued utilizing the Atomicals protocol. Within the ARC-20 normal, tokens are represented with satoshis, that are the native unit of the Bitcoin blockchain (1 BTC consists of 100 million satoshis).
ARC-20 is a fungible token normal for Bitcoin
The idea of fungible tokens was popularized within the cryptocurrency house by Ethereum, the place they’re sometimes issued utilizing the ERC-20 normal. Sure ERC-20 tokens have achieved large market capitalizations – a number of the largest fungible tokens available on the market at present embrace UNI, SHIB, LDO, and, after all, stablecoins.
The power to mint fungible tokens is on the market on virtually each blockchain platform that has general-purpose good contracts. For instance, there are fungible tokens on Solana (SLP tokens), BNB Chain (BEP-20 tokens), Cardano (native tokens), and so forth.
Whereas Bitcoin’s good contracts functionality is much more restricted, builders have provide you with inventive methods to signify various kinds of digital belongings (fungible and non-fungible tokens) on the Bitcoin blockchain.
The ARC-20 token normal is enabled by the Atomicals Protocol, which is a method to create each fungible and non-fungible tokens on Bitcoin. The Atomicals staff refers back to the digital belongings that may be created by the protocol as “digital objects”.
Minting ARC-20 tokens
Anybody can create an ARC-20 token and decide its provide, ticker and metadata (for instance official web site, social media hyperlinks and a picture). Nonetheless, since every ARC-20 token is represented by 1 satoshi, there’s truly a pracitcal restrict to what number of ARC-20 tokens somebody can mint.
That is totally different from the ERC-20 normal for instance, the place you may make a token’s provide as large as you need for no further price when you’re creating it. For instance, many meme cash issued on blockchains reminiscent of Ethereum have a provide of tons of of trillions of tokens.
The method of minting ARC-20 tokens and its implications on token provide are arguably probably the most distinctive side of ARC-20 tokens when in comparison with different fungible token requirements in use at present, so let’s clarify it in a bit extra element.
Decentralized ARC-20 token minting
The decentralized ARC-20 token minting mode permits the creator of the token to specify what number of mints of the token are allowed, and what number of tokens are issued in a single mint. By itself, this doesn’t create any tokens, however customers who need the token can mint them.
Direct ARC-20 token minting
Within the direct minting mode, the person creating the ARC-20 token creates an output that accommodates the overall provide the token. For instance, if you wish to create a token with a provide of 10 million with the direct minting mode, it’s essential create an output of 10 million satoshis (0.1 BTC). The extra tokens you need to mint, the extra BTC it’s essential present.
Find out how to use ARC-20 tokens?
As a way to maintain and transact with ARC-20 tokens, you want a Bitcoin pockets that helps UTXO choice, often known as “coin management”. Listed below are just a few examples of such wallets:

ARC-20 vs. BRC-20 – Atomicals and ordinals in contrast
ARC-20 tokens carry out an identical operate to BRC-20 tokens, that are additionally fungible tokens on the Bitcoin community, besides they’re issued by the Ordinals protocol.
Though Atomicals and Ordinals present very comparable utility, the 2 protocols do differ in some areas. Notably, Ordinals should be used with Taproot addresses for all use instances. Atomicals require the usage of Taproot addresses for minting and updating belongings, however not for transferring them.
Fungible tokens aren’t supported within the base Ordinals protocol, whereas Atomicals implement them because the first-class ARC-20 normal. The Atomicals protocol additionally helps two distinct varieties of minting fungible tokens.
One other distinction is that Ordinals doesn’t have a reputation service within the base protocol. In the meantime, Atomicals includes a identify service which is applied by first-class NFTs referred to as Realms.
To sum up, we will say that the Atomicals protocol affords a broader function set than Ordinals, however the Ordinals protocol has seen extra adoption up to now. To be honest, the Ordinals protocol has benefited from a head begin, because it was launched in January of 2023, whereas the Atomicals protocol was launched in September of 2023.
In the intervening time, the Ordinals protocol is much more common than the Atomicals protocol, though Atomicals have been gaining some traction. In whole, Atomicals protocol transaction have generated round 274 BTC in charges, whereas Ordinals protocol transactions have generated 4,050 BTC in charges.
If you wish to see a comparability between Ordinals and Atomicals based mostly on on-chain exercise, you’ll be able to try this useful Dune Analytics dashboard that compares the 2 protocols.
The underside line
ARC-20 tokens are fungible tokens issued on the Bitcoin blockchain utilizing the Atomicals Protocol. When ARC-20 tokens are minted, every token is represented with a satoshi, which is the smallest unit of BTC.
By way of performance, ARC-20 tokens are pretty much like BRC-20 tokens, that are issued utilizing the Ordinals protocol. At present, the Ordinals protocol is extra common than the Atomicals protocol, however the Atomicals protocol offers some further options which might assist it acquire extra adoption.
