Innovation happening across the Bitcoin ecosystem? We’re here for it. Join us as we research the new frontier of blockchain technology – the BRC-20 token standard. Let’s unravel what it’s all about and how to get involved. We aim to answer some of the burning questions and break down the complexities for our readers.

Introduction to the BRC-20 tokens: Highlights

Despite the absence of smart contract support in Bitcoin's base layer, the Taproot upgrade empowered developers to embed text and images within designated BTC transactions.

  • Following the innovation, the Ordinals pioneered a method to directly embed content into the tiniest units of BTC termed satoshis;

  • With satoshis capable of fitting text, visuals, music, and even complete games, the creation of NFTs within the Bitcoin ecosystem became more tangible than ever;

  • The BRC-20 represents a novel token standard utilizing Ordinals inscriptions for the minting and transfer of fungible tokens on the Bitcoin blockchain;

  • Bitcoin’s novel token standard differs from Ethereum ERC-20, where it’s not a smart-contract governed token but an inscription on the blockchain itself;

  • Whereas the new installment of tokens is limited in functionality at the current stage of development, the crypto community remains optimistic about discovering new applications for this emerging technology.

Let’s decode Ordinals, review inscriptions as the process of storing information and files within the Bitcoin blockchain, and learn how to actively engage and participate in this new narrative

From Ordinals to BRC-20

The history of BRC-20 tokens is tied to the inception of Ordinals, hence let’s uncover how the two concepts are connected.

Created by the innovative mind of Casey Rodarmor, Ordinals is a protocol that embeds notes known as 'inscriptions' in a single satoshi, the smallest fraction of a Bitcoin. Picture it as adding a personalized touch to a dollar bill.

The term 'Ordinals' embodies its purpose—a method of numbering sats. Consequently, each sat gains a distinctive identifier, allowing for a diverse range of data to be associated with different satoshis.

The versatility of Ordinals is not limited to text notes alone. The protocol accommodates a spectrum of inscriptions, ranging from images to interactive games. To illustrate, here’s a fun shooting game recreated on the blockchain using the Ordinals theory:

This flexibility opens the door to manifold creative possibilities, pushing the boundaries of what can be achieved within the BTC blockchain. One notable use case is unlocking the potential to create Bitcoin NFT.

More to that, the evolution of Ordinals has naturally given rise to the new token standard, marking the next phase in Bitcoin's technological journey.

Understanding BRC-20 token standard

The Bitcoin token following the ‘-20’ standard emerged as an equivalent to ERC-20 assets on the Ethereum network, facilitated by the innovative Ordinals technology.

Definition and characteristics

Similar to ERC-20, an advanced Bitcoin tokenization standard extends its capabilities to the creation of various fungible tokens, with a notable spotlight on the popular category of meme coins.

However, what sets BRC-20 tokens apart is their nuanced semi-fungible nature somehow comparable to Ethereum’s ERC-1155 standard. This uniqueness is attributed to the inherent finiteness of Bitcoins and satoshis which translates into a finite number of Ordinals.

It's also crucial to note that the new token norm is a separate use case derived from the Ordinals technology. It serves as an alternative method for tokenization within the Bitcoin ecosystem. Thus, it's crucial not to misinterpret BRC-20 assets as synonymous with Bitcoin NFTs.

The process of creating BRC-20 tokens

Setting up a BRC-20 token involves linking JSON-formatted text to a satoshi which results in several inscription steps.

Step 1: The ‘deploy’ inscription
After deciding on the name of the token and its overall supply, the first step is to inscribe a 'deploy' function. Here's an example of what this inscription might look like if we created a GetBlock (GETB) token on Bitcoin:

{
  "p": "brc-20",
  "op": "deploy",
  "tick": "getb",
  "max": "200200",
  "lim": "200",
}

Let's break down the parts for clarity:

  • "p": denoted the protocol type;
  • “op”: specifies the functions to execute;
  • “tick”: a four-character symbol of the asset;
  • “max”: signifies the maximum token supply;
  • “lim”: indicated the maximum quantity available per mint.

The ‘deploy’ method initiates the token registration within the system. ‘Mint’ and ‘transfer’ functions are also enabled by the new standard.

Step 2: Acquiring new tokens

Creating a ‘mint’ inscription allows acquiring new tokens to your wallet by passing the amount key as ‘amt’:

{ 
  "p": "brc-20",
  "op": "mint",
  "tick": "getb",
  "amt": "2000"
}

Once minted, tokens can be submitted to exchanges for sale at a desired price, traded through dedicated marketplaces, or sent to another wallet.

Step 3: Sending tokens
For moving tokens between wallets, it’s required to craft another inscription by adjusting the ‘mint’ function given above to 'transfer'.

These three key options would be enough to create and move BRC-20 tokens around. It's worth noting that each of these steps involves a small network charge, and the exact amount can vary significantly depending on the up-to-minute Bitcoin fee rate.

To give you an estimate, here's the expected cost to process the transaction containing the actual script from 'Step 1' as of November 22, 2023:

BRC-20 token applications

As a new concept in the blockchain space, BRCs are making their initial strides in the market. While meme token projects currently dominate the scene, testing the capabilities of the Ordinals protocol.

ORDI and MEME, breaking ground as the inaugural meme coins with inscriptions, set the stage for the Bitcoin debuts of NALS, PIZA, and PEPE. Presently, this dynamic quintet commands an impressive 72% of the total BRC-20 market, as reported by CoinGecko.

While there’s not much application to these tokens other than trading for now, developers are rigorously exploring ways to add fundamental value to this emerging asset class.

Let’s review some potential utility they may bring to the world of BitFi, decentralized finance on Bitcoin.

Tokenization

The creation of Ordinals has made launching digital assets more accessible and intuitive for people without the complexities of deploying Solidity codes. This approach also provides an added layer of security, by leveraging the robustness of the Bitcoin network.

P2P transfers

Newly deployed fungible tokens on Bitcoin offer a seamless experience for users. These tokens can be directly transferred from one user to another in routine Bitcoin transactions, eliminating the need for smart contract interactions.

Fueling decentralized applications

BRC-20 tokens are expected to step into the decentralized finance arena, enabling users to stake, lend, and borrow within various applications.

Stablecoins

In May this year, Stable, a fiat on and off-ramp provider launched a #USD stablecoin based on the new Bitcoin standard. This move allowed BTC holders to store a fair equivalent of USD on Bitcoin, use it for payments, and get easier access to newly minted BRC tokens.

The current temporary suspension of #USD minting, resulting from Stably's former custodian's bankruptcy, doesn't overshadow the initiative's key takeaway: highlighting the potential for BTC stablecoins built on the new standard.

Overall, the introduction of a new type of tokens has not only broadened the functionalities of the world's first cryptocurrency but also made Bitcoin a dynamic platform for development.

BRC-20 Tokens vs. ERC-20 Tokens

Though both fall within the same asset class, the distinction between the two types of tokens becomes clearer upon closer examination.

ERC-20 tokens on Ethereum have necessitated the mastery of Solidity coding, a well-established routine in the crypto community. On the flip side, the BRC-20 creators defied convention, taking a unique route by inscribing data directly onto the satoshis of Bitcoin fully residing on-chain.

Ethereum's ERC-20 tokens thrive in an established environment of tools and frameworks available to developers to seamlessly integrate their tokens into the ecosystem. In contrast, Bitcoin tokens are venturing into uncharted territory and haven’t yet garnered the support of the wider developer community.
