Inside the Three-Layer Architecture of the Starcoin Native Bridge

Starcoin — Fri, 13 Mar 2026 21:49:01 GMT

In crypto, bridges are often talked about as a single mechanism: a tool that lets assets move from one chain to another.

But in reality, a secure bridge isn’t one mechanism.

It’s a system of responsibilities.

Verification, coordination, and execution all need to happen; and each of those roles carries different risks. When those responsibilities are tightly bundled together, the result can be fragile systems where a single failure compromises the entire bridge.

Over the past few years, the industry has learned this lesson the hard way. Some of the most well-known bridge failures happened not because bridging itself is impossible, but because too many responsibilities were concentrated in too few components.

A more resilient approach is architectural: separate the roles and let each part do its job clearly.

That design philosophy sits at the heart of the native bridge built by Starcoin.

The Logic Behind a Layered Bridge

Instead of treating a bridge as a monolithic service, Starcoin’s bridge architecture distributes responsibilities across three operational layers.

Each layer handles a specific task in the cross-chain process.

This structure improves not only security, but also transparency and operational reliability.

At a high level, the three layers correspond to:

Verification
Coordination
Execution

Together, they form a system where cross-chain activity can be validated, organized, and finalized without collapsing these roles into a single point of control.

Layer 1: Verification

The first responsibility in any bridge is proving that something actually happened on the source chain.

For example, if a user locks assets on one network, the bridge must confirm that the event genuinely occurred before any corresponding assets are released elsewhere.

In Starcoin’s bridge design, this step involves validator participation and threshold signatures.

Bridge nodes independently observe events and produce signatures. Once the required threshold is reached, the event becomes eligible to move forward in the bridging process.

The key advantage of this approach is that no single actor controls verification. Multiple participants contribute to confirming cross-chain events before anything progresses.

Layer 2: Coordination

After an event has been verified, the next challenge is coordination.

Signatures must be gathered, organized, and submitted in a way that preserves ordering and ensures that events are processed correctly.

Bridge nodes play a coordinating role here: collecting validator signatures, assembling them into a verifiable bundle, and preparing them for submission to the destination chain.

This layer acts as the operational middle ground of the bridge; ensuring that verified events move through the system in a structured way.

Layer 3: Execution

The final step is execution.

Once verification and coordination are complete, the destination chain processes the result. At this stage, the bridge triggers the appropriate on-chain action, such as minting or unlocking the corresponding asset.

Because Starcoin’s execution environment is built on the Move programming model, digital assets are handled with strict resource rules. These rules ensure assets cannot be accidentally duplicated or mishandled during execution.

The result is a bridging process where the final on-chain state change follows clearly verified inputs.

Infrastructure Before Value Transfer

Cross-chain value exchange is often discussed in terms of liquidity and connectivity. But before capital can safely move between ecosystems, the infrastructure responsible for that movement must be carefully designed.

That is why our native bridge architecture focuses on structural clarity before expansion.

We believe that cross-chain systems that are concerned about asset safety at the core, will be the future play to strengthen investors’ confidence and solve the structural weakness of diligent value transfer across ecosystems.

Capital Migration vs Capital Integration in Decentralized Systems

Starcoin — Fri, 27 Feb 2026 19:25:41 GMT

The Myth of Fragmentation

Cross-chain bridges are no longer novel.

Assets move between ecosystems daily. Liquidity jumps from one chain to another in search of yield, efficiency, or opportunity. From a technical standpoint, the industry has proven that value can move.

And yet, liquidity fragmentation persists. Why?

Because movement alone doesn’t solve fragmentation.

Too often, bridging liquidity into a system that isn’t technically prepared only relocates the problem. Capital arrives, but the underlying infrastructure struggles to absorb, coordinate, and compound that inflow.

The bridge functions.

The destination strains.

Liquidity exchange becomes transactional, not transformative.

Infrastructure Before Inflow

At Starcoin, our approach has always been different.

We did not begin with “how do we bring liquidity in?”

We began with: “how do we build infrastructure that can responsibly handle it?”

For years, Starcoin’s development has focused on execution maturity, resource safety, and long-term scalability. The foundation came first.

This foundation includes:

Move’s resource-oriented programming model, ensuring digital assets cannot be duplicated or mishandled.
Parallel execution through Block-STM–inspired optimization (TurboSTM), increasing throughput without sacrificing determinism.
FlexiDAG consensus architecture, designed to improve performance and reduce bottlenecks.
Starcoin’s 10 BPS milestone on its enhanced PoW infrastructure, demonstrating sustained throughput improvements without abandoning the security guarantees of Proof-of-Work.
Starcoin’s dual-VM architecture, enabling compatibility across execution environments while preserving the integrity of Move’s core resource model.

These are not cosmetic upgrades. They are structural decisions. The lesson is that; before a system invites capital from the outside world, it must first be able to coordinate capital internally.

Why the Native Bridge Matters Now

With this technical groundwork in place, the Starcoin Native Bridge represents a natural progression.

The bridge connects Starcoin and EVM ecosystems through deliberate, security-mature design:

Threshold-based authority signing
Replay protection and isolated chain identifiers
Structured deployment pipelines from development to testnet to mainnet
Consistent Docker-based deployment to ensure environment reliability

As discussed in our recent Native Bridge AMA recap, the same production-grade software architecture runs across environments, reinforcing operational discipline from testing to deployment.

But what differentiates this bridge isn’t just its mechanics. It’s what it connects into.

A Prepared Ecosystem Awaits

A bridge is only as meaningful as the infrastructure it leads to.

Starcoin’s ecosystem has been optimizing for safety, parallel execution, and deterministic behavior long before cross-chain narratives intensified across the industry.

That means liquidity entering through the Native Bridge does not land in an experimental environment. It arrives in a system intentionally designed for:

Secure asset management
High-efficiency execution
Clear trust boundaries
Governance clarity

This is what meaningful asset mobility looks like. It doesn’t just enable inflow, but ensures that the inflow can integrate, compound, and interact within a coherent architecture.

Conclusion

Cross-chain transfer should not be treated like a growth shortcut. It should reflect infrastructure alignment.

At Starcoin, the Native Bridge represents an alignment between a security-mature Move architecture and the wider EVM ecosystem. It reflects a belief that capital deserves verified corridors.

Bridges alone do not resolve fragmentation.

Prepared systems do.

And when a technically mature ecosystem opens controlled, well-designed pathways to external liquidity, the outcome is not incremental. It is multiplicative — it is Capital Coordination.

When EVM Liquidity Meets Move Security

Starcoin — Tue, 24 Feb 2026 20:24:01 GMT

Ethereum holds ~50–60% of total DeFi TVL (Total Value Locked) — A staggering stat that points to the fragmentation of the decentralized finance ecosystem.

While owning a large percentage of onchain liquidity reflects Ethereum’s strengths, it underscores the lack of mature systems in the DeFi sphere, and the Move ecosystem particularly.

50–60% of total DeFi TVL laying on Ethereum, with the rest distributed across chains like BNB Chain, Avalanche, Polygon, Fantom, Arbitrum, Optimism, etc. spells it out clearly: crypto still lives in islands.

Imagine If Move and EVM Could Talk, Safely.

EVM chains built massive liquidity and DeFi depth.

Move-based chains engineer stronger safety guarantees and resource semantics.

Both powerful.

Both growing.

Mostly separate.

But imagine if they could talk — safely.

Not through fragile workarounds. Not through loosely defined trust assumptions.

But through intentional, security-mature infrastructure.

What would that unlock?

1) New Capital Flows

Liquidity wouldn’t have to choose a side.

Assets from EVM ecosystems could move into Move-based networks with clear verification and defined authority.

Move-native value could travel outward just as reliably.

That’s not just “bridging tokens.”

It’s unlocking capital mobility across fundamentally different execution environments because where liquidity flows, activity follows.

2) A Broader DeFi Surface Area

Every ecosystem develops its own strengths.

EVM chains: deep liquidity, mature primitives, battle-tested integrations.

Move chains: resource safety, deterministic execution, parallel processing models.

If these systems can circulate value securely, DeFi expands exponentially.

Protocols gain access to new user bases.

Builders gain access to new primitives.

Users gain access to more opportunity — without abandoning security guarantees.

3) Less Fragmentation

Right now, fragmentation is friction.

Different liquidity pools.

Duplicated ecosystems.

Assets stranded in silos.

Safe cross-chain transfer reduces that fragmentation.

Instead of isolated economies, you get connected ones — where value can circulate instead of stagnate.

4) More Composability

Composability is crypto’s superpower.

When chains can verify each other and move assets deliberately, new design space opens up:

Cross-chain vaults
Hybrid lending markets
Multi-chain collateral strategies
Identity and governance that travels with users

The more safely chains can “talk,” the more creatively developers can build.

A New Era: Real Change

A secure bridge between Move and EVM ecosystems will be the difference between capital locked in isolated rooms and capital flowing through more security-mature corridors.

This is fluid asset mobility, with safety first.

This is what Starcoin’s native bridge represents — integrated within the Starswap ecosystem.

The ultimate goal is to connect Move and EVM environments through defined authority models, explicit verification, and security-mature design.

More than just “inflow”, the objective is safer inflow, clearer trust boundaries and deliberate cross-chain communication.

When secure systems connect intentionally, liquidity doesn’t just move; it compounds. And when infrastructure is built with security at its core, the possibilities are simply exponential!

Recap: Starcoin Native Bridge AMA 2026

Starcoin — Fri, 13 Feb 2026 01:29:20 GMT

February 2026 marks the start of an exciting chapter in Starcoin’s cross-chain endeavors. The testnet launch of our native bridge on Starswap signals the firm resolve of the team to bring Starcoin’s advancements in asset security and scalability to the larger onchain community — starting with Ethereum.

Joining our community administrator, was Starswap’s core engineer, Valentine Reese. Together, they asked and answered trendy questions about the new bridge, from strategic reasoning to community topics and the future direction of cross-chain development in the Starcoin ecosystem.

Check out the full AMA recap below:

A: Hello Starcoiners! Welcome to today’s special session! We’ve all been feeling the excitement building up in the ecosystem.

Today, we aren’t just talking about a new feature — we are witnessing the opening of the Star-Gate. The Starcoin Native Bridge testnet is officially here to redefine how liquidity moves!

To give us the full deep dive, I am honored to invite the core engineering minds behind Starswap, our leading ecosystem partner.

They are the architects who built this bridge from the ground up to ensure it’s Move-native, secure, and lightning-fast.

Welcome to the Starcoin community, @ValentineReese! We’re thrilled to have you here.

VR: Hello everyone, I am Valentine, a core engineer at Staraswap. I’m excited to share an update on the bridge and provide more details for everyone.

A: Today’s session will last about 15 minutes. I’ll be asking our guest some key questions that the community has been buzzing about. After that, we might open the floor for a few quick questions if time permits. So. The chat is now muted so we can all focus on the alpha. Let’s dive in!

First Q1，What exactly does this Native Bridge do? Which chains are supported?

VR: Simply put, the Starcoin Native Bridge is the official, high-security highway connecting the Starcoin and Ethereum ecosystems.

It allows you to move your assets safely between these two worlds. Currently supported Starcoin (Halley Testnet / Mainnet) and Ethereum (Sepolia Testnet / Mainnet),We’re already planning to expand to more EVM-compatible chains very soon!

A: And Q2, How long does a transfer take? And what about gas fees?

VR: Speed depends on the confirmation time of both chains. Starcoin to Ethereum, Usually 5–15 mins, depends on ETH congestion, Ethereum to Starcoin, usually 3–10 mins. About safety buffer, there’s a slight delay between approve and claim to detect any abnormal on-chain behavior, It’s shorter than the finalization time, so it won’t slow you down much. About fees, you’ll pay gas on the source chain when starting the transfer, and on the destination chain when you approve and claim.

A: How secure is the Bridge? What happens if a node gets hacked?

VR: Security is our top priority, we use a multi-sig and threshold mechanism. Multi-Node, we run 3 independent Bridge Authority nodes. An attacker can’t fake a middleman because only registered nodes in the contract are valid. 2/3 quorum,

No transaction happens unless at least 2 out of 3 nodes sign off on it. Isolation, private keys are stored in encrypted k8s secrets, each node runs in its own isolated instance. Even if one node is compromised, the attacker cannot move any funds without the other signatures. Our monitoring system would instantly flag and isolate the problem node. So about Chain ID Isolation, we strictly separate Ethereum and Starcoin Chain IDs in the config so a transaction from one network can’t be “replayed” on another.

A: Next up, let’s talk about,How do you prevent Double-Spending or Replay Attacks?

VR: We have multiple layers of defense. First is Unique IDs, Every bridge event has a persistent unique identifier in our database to prevent double-processing. Second is on-chain Nonce, The smart contracts use a “nonce” system to ensure every transaction is one-of-a-kind. The third is Finality Check, We wait for “Finalized” blocks on Ethereum and have a specific finality mechanism enabled on the Starcoin side.

So about Chain ID Isolation, we strictly separate Ethereum and Starcoin Chain IDs in the config so a transaction from one network can’t be “replayed” on another.

A: What if all Bridge nodes go down? Are my assets lost?

VR: Your assets are 100% safe. Funds are locked in the smart contracts on-chain, not inside the nodes. If nodes go down, it only pauses the processing, your money is still there.

About persistence, We are using k8s StatefulSets, so when nodes reboot, they pick up exactly where they left off.

Once back online, the system automatically scans for any missed requests and processes them. You don’t need to do anything!

A: Now, let’s look at the technical side,How do you ensure the code works perfectly when moving from Dev to Mainnet?

VR: Our philosophy is: “Same Code, Different Config”

Our devs can spin up a full local environment (Starcoin Devnet, Anvil, Bridge Node and Indexer) in 30 seconds.

We use the exact same Docker image for testing and production, and we follow a “Gradual Launch” path: Local -> CI -> Testnet -> Mainnet, If anything goes wrong, we can roll back in seconds.

A: So,let’s deep dive, What happens during a chain “Reorg” (Forks)?

VR: This is a critical safety point. we use Dual Confirmation and Rollback. We only execute “mint” or “unlock” actions for “finalized” blocks (e.g., waiting 64 blocks on ETH or 16 on STC)

And our system constantly compares local data with the on-chain Hash, if a mismatch is found (a fork), the system automatically identifies the “Fork Point,” discards the unconfirmed events, and resyncs with the new “true” chain. No fake deposits, no double-entry.

A: If there’s an emergency, can you stop the Bridge quickly?

VR: Yes, we have an Asymmetric Kill-Switch. If our monitors detect an anomaly, a pre-signed “Pause” command can be triggered automatically. It’s high-speed and low-threshold for maximum protection.

To “Unpause,” it requires a high-threshold Quorum of signatures from the Bridge admins. We can also pause specific directions (e.g., only ETH to STC) to keep risks under control.

A: How do you change limits or add tokens? Are keys kept online?

VR: We use Offline Signing (Air-Gapped). Admins sign governance proposals (like raising the USDT limit) on an offline machine.

Once enough signatures are collected, the “Hex string” is sent to the chain. This covers all governance command, updating code, adding tokens, or changing committee members.

The master keys never touch the internet.

A: To wrap things up, here is our last question of the session: Which assets are supported now? What’s next?

VR: To ensure deep liquidity and maximum safety, we are launching with USDT first. However, our architecture is Universal. The smart contracts are already designed to handle any token (BTC, ETH, USDC, etc.)

Adding a new asset doesn’t require a code change, it just takes a quick governance vote. We will expand based on community demand.

A: Huge thanks to the Starswap team for the deep dive. 50 minutes well spent! I know we have more to cover, so make sure to join the Starswap community for further discussion!

Starcoin Native Bridge Guide

Starcoin — Fri, 06 Feb 2026 00:54:39 GMT

Starcoin Native Bridge Guide

Overview

This document describes the cross-chain process guide for the Halley–Sepolia networks: the Ethereum side is the Sepolia network, and the Starcoin side is the Halley network.

Preparation

Install wallets:

For Ethereum, install the MetaMask wallet extension:
MetaMask — Chrome Web Store

For Starcoin, install the Starmask wallet extension:
StarMask — Chrome Web Store

Starcoin Preparation

Get STC from the Halley faucet

Use the @StarcoinHalleyFaucet_bot on Telegram to claim STC. Example:

Ethereum Preparation

Switch network to Sepolia

Click the menu and select Network

Scroll to the bottom and enable “Show test networks”

Click the network selection dropdown

In the pop-up list, select Sepolia as the network.

Add USDT token to the list

USDT token address on Sepolia:
0xaA8E23Fb1079EA71e0a56F48a2aA51851D8433D0

Select the Sepolia network and enter the address into the input field.

Get Sepolia ETH

Obtain it from the following faucet:Sepolia PoW Faucet or from this one (Ethereum Sepolia Faucet)

Get USDT

Swap on Uniswap V2. First, switch the network to the testnet.

Select ETH on the Sepolia network as the token to sell.

Select USDT as the token to buy, and enter the address 0xaA8E23Fb1079EA71e0a56F48a2aA51851D8433D0.

Enter the amount to swap and proceed with the exchange.

After a successful swap, the wallet will show the corresponding test USDT.

Cross-chain Test

After obtaining the tokens as described above, we have sufficient USDT and STC to run a cross-chain test.

Our STC won’t have USDT out of thin air, so we must first bridge a certain amount of USDT from Ethereum to Starcoin. The typical test flow is to bridge USDT from Ethereum to Starcoin first, then bridge it back from Starcoin to Ethereum. The current version supports bridging only the USDT token.

Open https://bridge.starswap.xyz and connect wallets on both sides.

Enter the amount you want to bridge.

Click the Bridge asset button to start the cross-chain transfer.

After submitting the transaction, wait about ten minutes for the Sepolia network to confirm the block. Continue waiting until the transaction’s block reaches the finalized status.

During this period, the following prompts may appear. Don’t worry — the service is waiting for the transaction to be finalized. Refresh the page after a while. If Starmask disconnects, first confirm you are logged in to the Starmask account via the top-right wallet menu, then refresh the page to reload the wallet state and click the Connect button again.

Once the on-chain data is ready, the page will request the validator nodes to sign this transaction. After collecting all validator signatures, your wallet will automatically submit the aggregated signatures to the contract for verification. The screenshot shows the wallet confirmation dialog that pops up when the data is ready. Note: in the red highlighted field, manually enter 10,000,000 (ten million), and do it for every showing confirming gas input, Dont heartache for that, we have sufficient STC supplying; otherwise, the transaction may fail due to insufficient gas. This issue is a quirk of wallets on the testnet and does not occur on mainnet.

After a valid signature, the contract creates a cross-chain record. You will then need to perform a Claim action, which also requires signing in your wallet.

After a successful signature, the following view appears: the left side shows the transaction you submitted on Ethereum, and the right side shows the transaction you submitted on Starcoin.

You can see the bridged USDT balance in your wallet; the reverse direction works the same way.

Building the Future of Move Ecosystem, Together.

The launch of the Starcoin Native Bridge Testnet is more than just a technical milestone; it’s the cornerstone of a boundless liquidity era for Starswap. By participating in this testnet, you are not just testing a product — you are helping us forge a more secure, native, and seamless path between Starcoin and the broader Web3 world.

Your feedback is our fuel. If you encounter any issues or have suggestions to make the experience even smoother, please join our community and let us know.

Let’s ignite the stars. 🌌

Starcoin PoW: Anchoring Move Assets with Bitcoin-Grade Trust

Starcoin — Sun, 30 Nov 2025 16:09:13 GMT

In the clamor of the crypto world, we have weathered numerous bull-and-bear cycles. While everything seems rationalized during market fervor, it is only when the tide recedes and the market enters a long slump — the “crypto winter” — that a project’s core principles and design choices are truly put to the test.

At this juncture, a widespread “involution” occurs: many projects over-compete on marketing and unnecessary features just to stand out. However, a deeper risk is simultaneously exposed: the governance risk of PoS (Proof of Stake) chains.

In a bull market, high token prices can easily mask underlying governance flaws. But during a bear market, PoS token holders face immense pressure to maintain economic stability, leading to potential risks such as:

Aggressively reducing the inflation rate to induce scarcity, which can directly jeopardize validator revenue and the network’s long-term security.
Rapidly changing core protocol rules to cope with short-term market fluctuations or cater to the interests of a few large stakers.

The risk of such centralized decision-making renders the underlying trust foundation for DeFi, NFTs, or other Move assets relying on these L1 protocols increasingly fragile. For assets seeking decades of immutability and durability, this is a fatal flaw.

The Anti-Cyclical Nature of PoW: Bitcoin-Level Network Neutrality

Starcoin has chosen a distinct path: its adherence to the PoW (Proof of Work) mechanism is a direct consequence of its deep understanding of this cyclical risk.

The trust provided by PoW is “Bitcoin-grade,” possessing an inherent anti-cyclical network neutrality:

Security Not Dependent on Token Price: A PoS chain’s security is directly tied to its token’s market price. If the token price plummets, the cost to execute a 51% attack drops proportionally. PoW, conversely, relies on real-world energy consumption and hardware deployment (hashing power costs). The cost to attack Starcoin is a tangible expenditure on electricity and equipment, ensuring its security boundary remains robust even during market troughs.
Governance Minimalist Approach: PoW delegates governance power to computation and code, rather than capital (token holders). This drastically reduces human motivation and capability to intervene in the protocol. Starcoin inherits Bitcoin’s minimalist, difficult-to-change philosophy, ensuring its role as the immovable foundation of trust for the Move ecosystem.

Simply put, PoW ensures Starcoin remains a “trust-minimized” platform. It doesn’t promise high APYs or chase short-term trends; it promises only one thing: the underlying ledger for your Move assets will be as immutable and unwavering as Bitcoin’s, regardless of market volatility.

Long-Term Value: Infusing Decades of Durability

Only this kind of unshakable L1 trust can truly attract two crucial participants: institutions and long-term capital.

They do not seek a platform promising a quick 10x return, but an infrastructure guaranteed to operate securely for decades.

Institutional Users: Whether issuing RWAs (Real World Assets) or building large financial infrastructures, the primary consideration for institutions is durability and compliance. An underlying L1 susceptible to governance risks is unacceptable. The network neutrality provided by Starcoin’s PoW is the basis for this “digital permanence.”
The Trust Cornerstone for Move Assets: Starcoin marries the ultimate trust of PoW with the asset security features of the Move language. This means Move assets built on Starcoin not only benefit from Move’s formal verification safety but also possess the ultimate, censorship-resistant underlying trust provided by PoW. This dual guarantee makes Starcoin the ideal venue for Move assets seeking the infusion of the “Bitcoin Spirit.”

Navigating the cycles and adhering to principles — this is the core rationale for Starcoin’s persistence in PoW. It is forging an “immortal ledger” for Move assets, a foundational trust layer capable of bearing the digital wealth of society for decades to come.

Starcoin believes that amidst cyclical volatility, the cost of trust is the only long-term moat. PoW grants it the ability to traverse these cycles, allowing it to bring Bitcoin-grade network neutrality to the future of the Move ecosystem.

Developer Progress Review: Focused on Core Efficiency and Robust Architecture

Starcoin — Thu, 13 Nov 2025 18:07:41 GMT

In the recent development cycle, our core team maintained a strong focus on optimizing the efficiency, stability, and scalability of the underlying infrastructure. We believe that professional engineering discipline is the foundation for the long-term success of the project. This review highlights improvements in network throughput, enhancements to our high-concurrency architecture, and strategic steps toward future interoperability.

1. A Significant Leap in Underlying Performance

Maximizing network throughput and transaction confirmation speed remains our paramount goal. Through in-depth analysis and improvement of core execution paths, we have achieved a substantial leap in transaction processing efficiency.

Firstly, we implemented critical adjustments to the State Root calculation logic. By precisely narrowing the scope of data required for verification, the time needed to validate transactions has been dramatically reduced. This optimization, coupled with the integration of configuration and caching mechanisms, has also significantly accelerated VM2 (Move Virtual Machine) execution speed. These improvements collectively lower block confirmation latency and unlock higher potential network throughput.

2. Architectural Deepening: Advancing Concurrency and Throughput

To prepare for increased transaction load and demands for parallel processing, we have introduced key upgrades to our core architecture.

In the area of parallelized on-chain resource reading, we replaced the previous mutex-based caching mechanism with QuickCache. QuickCache provides internal thread safety, effectively eliminating lock contention in high-concurrency scenarios, which in turn dramatically boosts the system’s throughput and response speed during parallel execution.

Furthermore, we targeted potential bottlenecks in the transaction lifecycle by optimizing the Transaction Pool (TxPool). We implemented a batch write functionality and fine-tuned parameters such as maximum transaction count and memory usage. These steps significantly enhanced the TxPool’s capacity for concurrent handling under high load, ensuring every stage of the transaction process is efficient and non-blocking.

3. Feature Finalization and Ensuring System Stability

System robustness is paramount to providing reliable service. During this cycle, we completed critical feature finalization and core component fixes.

We successfully identified and resolved a key bug affecting Fungible Asset parallel execution, which was caused by an incorrect dataview type following its integration into the main branch. This fix is crucial for ensuring the absolute correctness and stability of asset operations across all parallel execution environments.

Simultaneously, the core logic for Transaction Proof (Tx Proof) has been fully refactored. By encapsulating and standardizing the verification procedures for both VM1 and VM2, we simplify the complexity for client-side verification, thereby enhancing data verifiability and the overall trust foundation of the system.

4. Forward-Looking Strategy: Preparing for Ecosystem Interoperability

A healthy ecosystem requires openness and connectivity. We are strategically planning for external integration.

Our core team has initiated preliminary technical research and feasibility analysis into efficient cross-chain connectivity solutions. This work aims to establish reliable technical reserves by evaluating various cross-chain technology stacks. It demonstrates our commitment to building an open, interoperable ecosystem where assets and information can flow freely and securely in the future.

Conclusion

This progress review underscores the team’s persistent dedication to performance enhancement, architectural optimization, and stability assurance. We firmly believe that this kind of dedicated investment in core engineering strengthens the project’s long-term competitive edge. We will continue to proceed methodically and look forward to sharing more positive outcomes with the community in the next development cycle.

Fungible Assets: Starcoin Advances Toward Flexible and Scalable DeFi

Starcoin — Thu, 06 Nov 2025 19:13:44 GMT

The future of DeFi requires assets to not only be interchangeable but also flexible enough to adapt to the dynamic demands of markets and governance. Starcoin, a PoW-based blockchain utilizing the Move language, positions itself as a “high-performance engine driving the next generation of on-chain innovation.” By adopting the Fungible Asset (FA) standard, Starcoin achieves a breakthrough. Inspired by Aptos, Starcoin’s FA upgrade transforms wallets, DAOs, and governance from rigid structures into scalable engines. For DeFi developers and DAO enthusiasts, this positions Starcoin as a pioneer in on-chain innovation!

Fungible Asset Standard: Dynamic Management Based on Objects

Starcoin’s FA standard shifts from static resources (such as CoinStore) to runtime dynamic assets based on objects. Traditional models fix assets to accounts at compile time, limiting scalability — like a wallet that can only handle a single currency. FA disrupts this model: assets are derived from independent storage addresses, supporting cross-type reads and writes without recompilation. This design draws from Aptos’s FA framework, ensuring backward compatibility through a seamless genesis upgrade. Developers can easily build FA-supported contracts, leveraging Move’s resource-oriented paradigm to guarantee security. It’s like equipping DeFi with a “multi-functional engine” to drive on-chain innovation!

Wallet Upgrades: From Static to Adaptive Storage

Traditional wallets are single-function storage solutions, where querying balances requires fixed paths (e.g., 0x1::Coin::CoinStore). FA turns wallets into “multi-tool kits”: via the primary fungible storage (0x1::FungibleAsset::FungibleStore), it enables runtime management of multiple assets. Users can deposit and withdraw STC, stablecoins, or yield assets without custom scripts. This lowers the user experience barrier: imagine a wallet that automatically aggregates DeFi positions from fungible DAOs, using FA-derived addresses for atomic swaps. For enterprise adopters, this means enhanced compliance — auditable, verifiable asset flows that adapt to regulatory changes with zero disruption.

Empowering DAOs and Governance: Community-Driven Scalability

DAOs rely on participation, but traditional governance structures are rigid. Starcoin’s FA wraps voting tokens in FungibleStore, supporting complex proposals like fund reallocation or upgrade votes. The genesis upgrade converts old Coin to FA, allowing DAOs to stake diverse assets (STC for voting, NFTs for vetoes), with built-in extensibility. Similar to the evolution of MakerDAO’s MKR, Starcoin DAOs enable automated execution — once a proposal reaches quorum, it triggers FA transfers, with Move verification preventing vulnerabilities. Small holders can amplify their influence through FA-shared storage, democratizing decision-making. Under PoW security, this provides the momentum for community-driven innovation.

Benefits for DeFi and DAOs: Scalability and Innovation

FA’s object-based model injects vitality into DeFi: dynamic resources support composable protocols, such as automated cross-asset balancing in yield farms, eliminating liquidity silos. In DAOs, FA simplifies multi-token treasury operations, reducing gas costs for complex votes by 2–3 times, while Move’s linear types prevent double-spending.At the application level, FA lowers barriers for cross-DAO collaboration (e.g., shared FA pools for joint investments), enhancing governance token liquidity. Starcoin’s PoW ensures tamper-proof finality, providing security guarantees for lending markets or prediction DAOs.

Future Potential: FA-Driven Swaps and Broader Prospects

FA opens new pathways for Swap protocols. Imagine a v2 Swap using FA-derived addresses for atomic multi-hop trades, bypassing fragmented liquidity pools and reducing slippage. This can integrate with real-world assets (RWA), tokenizing bonds or yield-bearing assets into FA storage for DAO voting management.

Starcoin: High-Performance PoW Move Blockchain — First Choice for RWA Tokenization

As the crypto-financial market matures in 2025, institutional capital is increasingly focused on real-world assets (RWA). This trend places the highest demands on underlying blockchain infrastructure: it must combine the resilience of decentralization with high-performance execution. Traditional public chains often trade off between security and speed, but Starcoin was born to solve this structural dilemma.

Starcoin is not a mere stack of technologies. By integrating PoW, Move contracts, and parallelization, it delivers a high-security, high-efficiency solution. Our goal is to provide a trusted, sustainable environment for RWA assets and institutional-grade applications.

PoW: Decentralized Foundation

Starcoin remains committed to Proof of Work (PoW), inheriting its core value: decentralized censorship resistance and historically proven resilience.

Network security is backed by real-world computational cost, making Starcoin a highly autonomous and neutral financial infrastructure. For RWAs requiring long-term stability and resistance to regulatory interference, PoW provides a powerful trust foundation. We believe this transparent, decentralized mechanism is the best guarantee of permanence and immutability for high-value assets. Starcoin’s PoW foundation is our promise of long-term, reliable service in global markets.

2. Move: Code-Level Safety

Network security is only part of Starcoin’s solution. We recognize that smart contract vulnerabilities are a primary risk to on-chain assets. That’s why Starcoin chose Move, a language that provides code-level assurance.

At its core, Move’s resource model treats tokens as non-duplicable, non-reusable digital assets. This design eliminates common vulnerabilities like double-spending or asset loss at the architectural level. Move’s formal verification and modular design greatly simplify contract auditing and enhance code reliability. Built on Move, Starcoin offers a high-standard contract environment for RWA tokenization and custody — effectively reducing institutional concerns about code exploits.

3. Performance: 10 BPS Breakthrough

Starcoin is breaking the stereotype that “PoW is slow.” Through technical innovation, we prove that security and performance can coexist.

Starcoin deploys proprietary parallelization technologies such as TurboSTM and FlexiDAG (Flexible Directed Acyclic Graph). These innovations enable efficient parallel transaction processing, shattering the performance limits of traditional PoW chains. Starcoin consistently achieves 10 BPS (blocks per second) — a level of efficiency that not only enhances user experience but, more importantly, enables high-frequency RWA trading and positions Starcoin as a high-performance settlement layer.

Conclusion

In today’s evolving crypto-financial landscape, Starcoin offers a unique solution that balances decentralization, code-level security, and high performance. We leverage PoW’s resilience, Move’s safety, and 10 BPS execution efficiency to build a trusted, scalable infrastructure for RWAs and institutional applications.

Starcoin invites global developers and institutional partners to explore the immense potential of a PoW-based Move Chain in defining the next generation of secure, efficient financial services.

Twitter Space AMA Recap: Starcoin Q3 Dev Recap

Starcoin — Mon, 27 Oct 2025 17:33:51 GMT

Host: (Ashely)
Hey friends, welcome to the Starcoin Dev Recap Space! I’m Ashely, your host today — glad you’re here.

It’s been an exciting time in crypto. There are so many new ideas and projects popping up, and it really shows how fast this space is moving. That energy keeps Starcoin moving forward.

Today we’ll do a quick catch-up on everything that’s been happening from mid-August to mid-October.

by the way For those who are new here, Starcoin is a PoW-based Move chain, focused on strong performance, solid security, and long-term building.

I’m joined by our lovely engineers — Bob, Dio, and Fikgol — and our community manager Buchii, who’ll be taking your questions a little later.

Alright, let’s get started.
Bob, wanna kick things off?
What’s been going on with your work? — anything cool to share?

Bob:
Ok, Thanks! I’ve been focusing lately on building and optimizing compatibility for our dual virtual machines (VM1 and VM2), while also advancing the data migration from Starcoin 1.0 and implementing the new Framework standards for VM2.

First off, let’s talk about the dual VM setup: We’ve cleverly packaged transactions from both virtual machines into the same block and merged their state roots into a unified state root for the entire blockchain. This not only guarantees seamless compatibility but also lays a solid foundation for future expansions.

Next, on data migration: To ensure full compatibility with Starcoin 1.0, we’ve preserved all asset and contract data, including STC assets, NFTs, and deployed code. When miners boot up the new version, this data serves as the genesis foundation for VM1. Once the chain starts producing blocks normally, users can carry on with transfers, API calls, and other operations just like before — meaning all existing on-chain dApps keep running smoothly.

Finally, regarding VM2’s new Framework standards: We’ve adopted a design that’s compatible with Aptos Objects, so developers can deploy dApps from Aptos to Starcoin with minimal changes, achieving code-level seamless compatibility.

So, think of the new Starcoin version as a dual-engine race car: VM1 keeps legacy apps cruising steadily, while VM2 revs up innovation for new DeFi projects. We’ve nailed it — no downtime required, apps run faster, and everyone gets a smoother blockchain ride! That all, Thanks

Host:
Nice one, Bob — sounds like things are really moving fast.
Dio, how about you? What’s been exciting or challenging on your side these past few weeks?

Dio:
Hey, happy to be here! We’ve been tweaking parallel execution to make things fly. Gas fees collection used to slow us down — threads tripping over one account. We fixed it with distributed gas accounts and some neat Rust code, spreading fees like cars across multiple lanes. Meanwhile, we have reduced resource competition and performed some resource preloading. Now, VM TPS is up to 14,000 with parallel execution from original 3,000 by serialize execution on macmini m4 chip, and transaction checks are under 1ms, down from 70ms, thanks to our VM reuse pool. It’s like a multi-core processor — transactions zoom through! Users get fast, cheap DeFi trades; devs build apps easier. And we keep PoW’s trust, so no sketchy shortcuts. Pretty sweet, right?

Host :
That’s awesome, Dio. Love hearing how the system’s getting stronger and smoother.
Fikgol, — what’s new with you? What’s been keeping you busy recently?

Fikgol :
Yo, thanks! We’ve made big progress lately with FlexiDAG and it’s performance.

Firstly, we’re finished integrating FlexiDAG with dual-VM. We ran tests to squash DAG commit bugs, keeping consensus stable even when the network gets busy.

Secondly, We optimized our CI/CD process and made it more smoothly — tests are crazy fast now, and the cluster maintenance costs went down by about forty percent.

And at last, We tuned the network settings, dropping block relay times from 5–10 seconds to 1–2 seconds — 5 times speed boost.

Right now, FlexiDAG’s like a multi-lane highway, Users get buttery-smooth trades, developers build fast apps, and PoW keeps it rock-solid!

Host :
Wow, that’s a lot of progress. Everything’s faster and leaner — love it.

Before we jump to Q&A, let’s do a quick fun one:
What’s one thing from the past two months that you’re most proud of or excited about?

Bob:
I think ,Starcoin Cookbook’s a big one — updated with DeFi and group resource guides. Devs can deploy VM2 contracts 50% faster now.

Dio:
Yeah, TPS at 14,000, no more gas fee distribution conflict, and sub-1ms checks. We’re also tougher against spam, keeping DeFi safe.

Fikgol (7:40–8:00):
about me, I think, Node migration to DigitalOcean cut costs 40% and boosted relays 5–10x. Our mainnet’s lean and ready for more apps!

Host:
Awesome — thanks, guys! Great to hear all those highlights.
Now let’s bring in our Community Manager Buchii for a few questions for our engineers, and some popular questions from the community.

Community Manager (Buchii):
Thanks, Team, excellent updates. First question that I think our community would love to learn some more about: “How does dual-VM make DeFi easier for devs?”

Bob:
Great question! Dual-VM’s like having two toolkits — VM1 handles old apps, VM2 lets devs build secure, fast DeFi contracts without breaking a sweat.

Host:
Love it! Next: “What’s FlexiDAG’s edge for everyday users?”

Fikgol:
It’s speed! FlexiDAG’s multi-lane setup means your trades or payments go through crazy fast, no waiting, no high fees.

Buchii:
Perfect. Great insights for the community -

Any questions from the listeners here in the Space?”
