Terra: A Decentralized Payment Protocol Based on Algorithmic Stablecoins

What is Terra

Friends, imagine the stable currencies we rely on in daily life, like the US dollar or Chinese yuan. Their prices are relatively stable, making it easy for us to buy things and save money. But in the blockchain world, cryptocurrency prices fluctuate wildly—today they might soar, tomorrow they might crash—making them hard to use for everyday payments like the fiat currencies we’re used to.

and its core token were originally created to solve this problem. The goal is to create a “digital currency” that enjoys the benefits of blockchain technology (such as fast transfers and low costs) while maintaining price stability, making it convenient for daily payments and transactions.

You can think of Terra as a “smart currency system.” In this system, there are two main types of currency: one is the

(like the former TerraUSD, UST, which tried to peg to the US dollar and maintain a $1 value), and the other is the used to keep the stablecoin system running smoothly.

Its core use case is to provide a stable and efficient payment platform for e-commerce, allowing people to transact on the blockchain as easily as using a bank card.

Project Vision and Value Proposition

The vision of the Terra project is to promote the widespread adoption of blockchain technology by issuing stablecoins pegged to fiat currencies, and to build a new digital economic system. When founders Do Kwon and Daniel Shin created Terra in 2018, they aimed to offer a blockchain payment solution that was price-stable, faster, and cheaper to settle, thereby accelerating blockchain adoption.

The core problem it seeks to solve is the high price volatility of traditional cryptocurrencies, which makes them unsuitable as everyday payment tools. Terra hopes to combine the stability of fiat with the censorship resistance of Bitcoin, offering fast and low-cost settlement services. Its uniqueness lies in not relying on traditional assets like bank deposits to back the stablecoin’s value, but instead maintaining the peg through a complex “mint and burn” algorithmic mechanism.

Among similar projects, many stablecoins (like USDT, USDC) are usually backed by actual dollar reserves or other assets, while TerraUSD (UST) is an “algorithmic stablecoin” whose stability is maintained entirely by the minting and burning of LUNA tokens. This makes it more “decentralized” by design, theoretically avoiding the trust risks of centralized entities.

Technical Features

The Terra blockchain can be seen as a high-performance “ledger,” with its underlying technology mainly built on the Cosmos SDK framework. You can think of Cosmos SDK as a “blockchain toolbox” that provides many ready-made modules, making it easier and faster for developers to build their own blockchains.

Its consensus mechanism—how everyone agrees on transaction records—uses

. This is like a community voting to elect representatives to manage public affairs. LUNA token holders can delegate their LUNA to “validators,” who are responsible for verifying transactions, packaging blocks, and maintaining network security. Validators get voting power based on the amount of LUNA staked and receive rewards accordingly.

The system’s biggest technical feature is its unique “dual-token system” and “algorithmic stability mechanism.” Specifically:

• Terra stablecoins (e.g., UST):
  The goal is to keep prices stable, such as 1 UST always equaling $1.
• LUNA token:
  Acts as the network’s “fuel” and “regulator.” It has three main functions:
  1. Governance:
     LUNA holders can participate in community proposal voting to decide the project’s future direction.
  2. Staking:
     LUNA can be staked to support network security and earn rewards.
  3. Stablecoin stability:
     This is the most core and complex part. When UST’s price deviates from $1, the system incentivizes users to arbitrage by minting or burning LUNA, pulling UST’s price back to $1.
     • If UST is below $1 (e.g., $0.98), arbitrageurs can buy UST at $0.98, then exchange 1 UST for $1 worth of LUNA, earning a 2-cent profit. This process burns UST, reducing its supply and pushing its price back up to $1.
     • If UST is above $1 (e.g., $1.02), arbitrageurs can use $1 worth of LUNA to mint 1 UST, then sell UST for $1.02, earning a 2-cent profit. This increases UST supply, pulling its price back down to $1.

This mechanism sounds clever in theory, but faces huge challenges in practice, especially during extreme market volatility.

Tokenomics

The Terra ecosystem was originally designed around two main tokens:

and (such as UST).

LUNA Token

• Token symbol:
  LUNA (for the original chain; after the collapse, the new chain’s token is LUNA2, and the old chain’s token was renamed LUNC).
• Issuing chain:
  Terra blockchain (based on Cosmos SDK).
• Total supply or issuance mechanism:
  The original LUNA was designed with a maximum supply of 1 billion tokens; if this number was exceeded, the protocol would automatically burn LUNA. However, after the UST depeg event, LUNA’s supply skyrocketed from about 345 million to several trillion in an attempt to maintain the stablecoin.
• Inflation/Burn:
  LUNA’s supply is dynamic, closely tied to the minting and burning mechanism with UST. When UST is minted, an equivalent amount of LUNA is burned; when UST is burned, an equivalent amount of LUNA is minted. Additionally, LUNA stakers and validators earn rewards from transaction fees.
• Token utility:
  • Stablecoin stabilizer:
    LUNA’s main function is to absorb price fluctuations of Terra stablecoins and maintain their peg to fiat.
  • Staking:
    Holders can stake LUNA to secure the network and earn rewards.
  • Governance:
    LUNA holders can vote on upgrades and parameter changes to the Terra protocol.
  • Paying fees:
    Used to pay network transaction fees.
• Token distribution and unlock info:
  The initial distribution details of the original LUNA are not clearly provided in public sources, but its issuance and circulation were tied to ecosystem growth and UST supply and demand. After the UST collapse, Terra 2.0 (LUNA2) adopted an airdrop mechanism, distributing new LUNA2 to affected LUNA Classic (LUNC) and UST holders.

The core of this algorithmic stablecoin model is the arbitrage mechanism between LUNA and UST, aiming to keep UST’s value stable by adjusting LUNA’s supply. However, this algorithmic mechanism without real asset collateral proved extremely fragile and risky under extreme market conditions.

Team, Governance, and Funding

Core Members

The Terra project was co-founded in 2018 by

and , and developed by their company . Do Kwon was the CEO of Terraform Labs and played a central role in the project’s development.

Team Features

Do Kwon is a Korean entrepreneur and software engineer, a Stanford graduate. Daniel Shin is the co-founder of Korea’s well-known e-commerce platform Ticket Monster. The team attracted funding from many prominent investment institutions in its early days.

Governance Mechanism

Terra adopted a decentralized governance model, where LUNA token holders can participate in governance by staking their tokens. This means they can vote on proposals for protocol parameter updates, feature improvements, etc., influencing the project’s direction. This approach aims to ensure community control and avoid excessive centralization.

Funding

Terra received substantial funding early on. In August 2018, the project raised $32 million from investors including Binance, Polychain Capital, FBG Capital, Hashed, and others. In 2021, Terraform Labs raised another $25 million from Galaxy Digital, Coinbase Ventures, and received $150 million from Arrington XRP Capital and others. To address potential UST depeg risks, the Terra ecosystem also established the “Luna Foundation Guard (LFG)” to reserve large amounts of Bitcoin and other non-correlated assets to support the UST peg in emergencies. However, during the 2022 crisis, these reserves ultimately failed to prevent UST’s collapse.

Roadmap

Since its inception, Terra has gone through a series of major milestones and events:

• January 2018:
  Do Kwon and Daniel Shin founded Terraform Labs and launched the Terra project.
• August 2018:
  The project raised $32 million in seed funding.
• April 2019:
  Terra mainnet officially launched, along with the Terra Station wallet and Terra Finder block explorer.
• Late 2020:
  TerraUSD (UST) and other stablecoins launched.
• 2021:
  Terra ecosystem grew rapidly, becoming a major force in DeFi, with total value locked (TVL) exceeding $20 billion at one point, making it the second-largest DeFi protocol. Anchor Protocol launched, offering up to 20% annual yield on UST deposits, attracting many users and funds.
• April 2022:
  LUNA price hit an all-time high, UST became the third-largest stablecoin.
• May 2022:
  UST depegged from the dollar, triggering massive sell-offs; LUNA’s price nearly went to zero in days, wiping out about $45 billion in market value and causing a huge shock to the entire crypto market.
• May 28, 2022:
  Founder Do Kwon proposed a “revival plan,” creating a new Terra chain (Terra 2.0) via hard fork. The original Terra chain was renamed Terra Classic, its token LUNA renamed LUNA Classic (LUNC), while the new chain’s token remained LUNA (LUNA2).
• March 2023:
  Do Kwon was arrested in Montenegro, facing multiple fraud charges.
• January 2024:
  Terraform Labs filed for bankruptcy.
• August 2025:
  Do Kwon pleaded guilty to multiple fraud charges in the US.

As for future plans, given the collapse of the original Terra ecosystem, Terraform Labs’ bankruptcy, and core team member Do Kwon’s legal troubles, the original grand roadmap is no longer applicable. The future development of Terra 2.0 and Terra Classic chains is now mainly community-driven and faces great uncertainty.

Common Risk Reminders

Friends, learning about Terra’s story, one of the biggest takeaways is understanding the risks in the crypto world. Terra’s collapse is one of the biggest events in crypto history, causing huge losses for investors.

• Economic Risks (especially inherent risks of algorithmic stablecoins):

  • Algorithmic stablecoin fragility:
    UST’s stability mechanism relied entirely on LUNA minting and burning, not on real asset collateral. In times of extreme market panic or large redemptions, this mechanism can fail, leading to the so-called “death spiral”: UST price drops -> massive LUNA minting to maintain UST peg -> LUNA supply surges, price crashes -> market loses confidence in UST -> more UST is dumped, cycle repeats, eventually both tokens go to zero.
  • Temptation and unsustainability of high yields:
    Anchor Protocol’s 20% annual yield on UST deposits attracted many users but was widely considered unsustainable. Such high yields may have “Ponzi scheme” characteristics; once inflows slow or stop, the system can’t be maintained.
  • Market sentiment and confidence:
    The crypto market is heavily influenced by sentiment. Once the market loses confidence in a project, even the cleverest technical design can collapse quickly.

• Technical and Security Risks:

  • Although the Terra blockchain itself, based on Cosmos SDK and DPoS, has a certain level of security, the economic model flaws in its stablecoin’s core algorithm were the root cause of the collapse.
  • Smart contract bugs, oracle attacks, etc., are also common technical risks for blockchain projects.

• Compliance and Operational Risks:

  • Regulatory uncertainty:
    Global crypto regulation is still evolving, and algorithmic stablecoins face especially strict scrutiny.
  • Legal actions and liability:
    Terra’s core team member Do Kwon faces multiple fraud charges and lawsuits due to the project’s collapse, showing the legal risks project operators may face.
  • Centralization risk:
    Despite claims of decentralization, the founders’ huge influence in project development and crisis management exposed a certain degree of centralization risk.

The above risks are not exhaustive. Every crypto project is highly uncertain. Always do thorough research before making any decisions.

Verification Checklist

To dig deeper into any blockchain project, here are some important information sources you can explore yourself:

• Block Explorer:

  • Terra Classic (LUNC) block explorer:
    You can search "Terra Classic explorer" or "LUNC explorer" to find tools for viewing old chain transaction records and network status, such as Atomscan or CoinStats.
  • Terra 2.0 (LUNA2) block explorer:
    Similarly, search "Terra 2.0 explorer" or "LUNA2 explorer" to view new chain data.
  • Function:
    These are like the blockchain’s “search engine” and “public ledger,” letting you query transaction history, block info, token holder addresses, and other public data.

• GitHub Activity:

  • You can search "Terraform Labs GitHub" to find the development team’s code repositories.
  • Function:
    The frequency of code commits, issue resolution, number of active contributors, etc., on GitHub can indirectly reflect the project’s development activity and transparency. An active GitHub repo usually means ongoing development and maintenance.

• Official Whitepaper:

  • Search "Terra whitepaper" to find the project’s original whitepaper and understand its core design concepts and technical details.

• Official Website and Social Media:

  • Visit the project’s official website (e.g., terra.money, but note it now points to Terra 2.0), and follow its official Twitter, forums, blogs, etc., for the latest updates and community discussions.

Project Summary

The Terra project, especially its original version (LUNA and UST) before the May 2022 collapse, was once a case full of innovation and controversy in the crypto space. It tried to solve the problem of high price volatility in traditional cryptocurrencies by combining a unique algorithmic mechanism, stablecoin (UST), and a volatile asset (LUNA), building a decentralized payment network.

The project’s vision was grand, and its early growth was rapid, becoming a DeFi giant and attracting much attention from investors and developers. However, its core algorithmic stability mechanism failed under extreme market pressure, ultimately leading to UST’s depeg and LUNA’s “death spiral” crash, with far-reaching impact on the entire crypto market.

Terra’s case vividly reveals the inherent risks of algorithmic stablecoins and the huge hidden dangers that may exist under high return promises (such as Anchor Protocol’s 20% high yield). It reminds us that no matter how clever the economic model, without solid collateral or enough resilience to withstand “bank run”-style sell-offs, it may be vulnerable.

After Terra’s collapse, although the community launched Terra 2.0 and retained the Terra Classic chain, its future prospects are highly uncertain, and the original team’s core members face serious legal issues. History teaches us to be cautious when investing in any crypto project, to thoroughly research its economic model, technical architecture, team background, and potential risks, and not to be blinded by short-term high return promises.
