![BSI.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/BSI_5f9d066fdd.jpg)

When the concept of shared security took off in the blockchain space, it had two massive new implications:

- Blockchains could use staked assets from another chain to secure theirs – making it substantially easier to launch new networks.
- Stakers could gain exposure to rewards from multiple chains using the same capital.

Both of these advantages have opened up huge opportunities for developers and crypto users alike. Ethereum was the first ecosystem to popularize shared security. But this year, the [Babylon protocol](https://babylonlabs.io/) began the process of unlocking Bitcoin's $2T market cap to secure every PoS network that wants to integrate instant crypto-economic security with staked BTC.

This development will change the entire blockchain ecosystem in unforeseeable ways. However, there are some immediately evident benefits for developers that are priming crypto for an explosion of Bitcoin Secured Networks (BSNs).

**[Build your Bitcoin Secured Network now →](https://www.ankr.com/bitcoin-secured-infrastructure/)**

## What is Bitcoin Secured Infrastructure?

**Bitcoin Secured Infrastructure is the name of Asphere’s solution for creating custom Bitcoin Secured Networks and Services for clients** (Asphere is the enterprise-level service company from the team behind Ankr)**.** These are Layer 1 or Layer 2 blockchains built with the vital integration of the Babylon protocol that enables shared security with Bitcoin. The new name is a shift from our previous “BTC L2” naming, which didn’t account for the creation of L1s and other possibilities such as services.

![123.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/123_fe6d3ccb92.jpg)

**Asphere has created BSNs-in-a-box by integrating its infrastructure with Babylon to give developers the ability to build new chains secured by BTC staking.** Babylon is a Cosmos SDK chain that allows Bitcoin holders to stake their BTC to secure other blockchains and protocols.

By leveraging the security and decentralization of Bitcoin, Asphere and Babylon can enhance the security of a variety of networks, including:

- **Layer 1 and Layer 2 blockchains:** Bitcoin Secured Infrastructure can be employed to secure new chains in a variety of ecosystems like Ethereum, Cosmos, and even Solana. Please note that the initial version of the service supports Cosmos as we extend support to other networks.
- **DA Layers:** Proof of Stake Data Availability layers can harness Babylon to instantly amplify their security posture with the vast pool of BTC to deter attacks.
- **Sequencers:** Sequencer platforms like Espresso Network can integrate with Babylon as Bitcoin Secured Infrastructure as a stronger foundation for L2 networks.
- **Data storage and oracles:** Networks like Filecoin and Chainlink can secure their data and oracle feeds, creating a layer of safety and reliability for protocols that rely on them.
- **DePIN & IoT networks:** Networks in the DePIN space like IoTeX can benefit from Babylon's security to protect their network nodes and data.

## Key Elements of Bitcoin Secured Infrastructure

**BTC Staking:** Bitcoin staking, facilitated by the Babylon protocol integration, offers enhanced security, increased trust, improved performance, access to a massive BTC user base, and innovative financial opportunities for developers building new blockchains. Notably, Babylon's Bitcoin staking protocol is **completely self-custodial and does not utilize bridges or wrapped/synthetic BTC.** Stakers stake native BTC via their own Bitcoin wallet and do not give up custody of their BTC when doing so.

**Bitcoin Timestamping:** By anchoring critical blockchain data onto the Bitcoin blockchain, developers can significantly bolster the security of their networks. This provides a **robust defense against attacks and vulnerabilities to PoS** chains that could compromise their integrity.

## Some Core Benefits of BSI

- **Secure Your Chain or Service With 21M Available BTC.** Launch bespoke Chains or Services with bootstrapped network security and liquidity by leveraging the $2T market cap securing the Bitcoin network.
- **Achieve the Fastest Possible Finality.** Create applications with high-speed finality perfect for DeFi, payments, or gaming, thanks to Babylon’s ultra-fast Finality Provider network.
- **Activate Bitcoin Holders.** Babylon enables BTC holders to gain rights to validate PoS chains and earn yields while also providing fast unbonding and scalable restaking.

## What Integrations Are Needed For Bitcoin Secured Networks?

![cosmos.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/cosmos_7d4f6fe39a.jpg)

**Cosmos SDK:** The Cosmos SDK provides a modular toolkit that allows developers to create independent blockchains that can interoperate with each other, forming a network of interconnected blockchains. This interoperability enables seamless communication and value transfer between different blockchains, fostering a more interconnected and efficient decentralized ecosystem.

**IBC:** The Inter-Blockchain Communication (IBC) protocol enables seamless communication and value transfer between independent blockchains within the Cosmos ecosystem. This interoperability allows different blockchains to share information and assets, creating a more interconnected and efficient decentralized network.

**Babylon BTC Staking Protocol:** Babylon enables new blockchains and services to use Bitcoin as a staking asset to enjoy more robust crypto-economic security than native tokens can provide. As a result, PoS systems will be able to utilize Babylon’s trustless scalable staking features to unlock value from the idle, unencumbered $1 trillion Bitcoin ecosystem. Babylon’s BTC staking protocol enables BTC stakers to trustlessly stake and restake their BTC on the Bitcoin blockchain.

## What Chains Are Currently Building Bitcoin Secured Infrastructure?

![zkb.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/zkb_1a5a6ee346.jpg)

Ankr is now a vital member of the ZkBoost Consortium, a collective of protocols with a shared mission: to create a neutral, open-source platform for simplifying and standardizing zero-knowledge (zk) proof generation through a unified API. Ankr’s new role allows us to drive innovation and scalability in one of the fastest-growing areas in the space.

Led by [Gevulot](https://gevulot.com/), the ZkBoost Consortium is at the forefront of advancing zk-proof technology, a pivotal solution that can reimagine security and privacy for blockchain networks and real-world use cases.

## What is the ZkBoost Consortium?

![000.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/000_61d92396ff.jpg)

**Source:** [Proof Supply Chain Abstraction](https://blog.gevulot.com/p/zkboost-proof-supply-chain-abstraction?triedRedirect=true)

The ZkBoost Consortium is an alliance of 30+ protocols and infrastructure providers seeking to establish a unified, standardized, and open-source approach to zk-proof generation.

Despite a massively increasing demand for proof generation, the consortium is addressing a critical issue in the fragmented state of how it is supplied. This year, many projects have entered the prover space. While competition is beneficial in driving innovation, the lack of a standardized infrastructure leads to inefficiencies. Currently, different rollups and zkApps must integrate with various networks for proving, leading to a complex and fragmented ecosystem that hinders widespread adoption.

ZkBoost's solution is elegant yet powerful—a generic abstraction layer for outsourced proving. By providing a single, standardized API, the ZkBoost framework enables L2 networks to seamlessly access various proving services, and proving networks can easily offer their services to a wide range of clients. This approach will streamline demand for zk-proof solutions across the ecosystem, benefiting all stakeholders, from developers to end-users.

## Why ZkBoost Matters for the Future of Blockchain

As the demand for zk-based apps grows, so does the complexity of integrating different proving solutions. This is where ZkBoost’s mission becomes critical. By creating a standardized platform, the consortium will:

- **Reduce Complexity:** A unified API eliminates the need for L2s or zk Apps to integrate multiple prover services independently, leading to streamlined proof generation.
- **Enhance Interoperability:** Standardizing the proving layer avoids fragmentation and ensures that L2 networks can effortlessly access the best proving solutions.
- **Foster Accessibility:** ZkBoost will make zk-proof technology accessible to a broader range of clients and developers, reducing barriers to entry for innovative projects that rely on zk-technology for privacy-preserving applications.
- **Boost Adoption:** By simplifying the integration process, ZkBoost accelerates the adoption of zk-proof technology, encouraging more developers to build zk-based applications and enabling faster scaling for L2 networks.

As zk-tech matures, the importance of a unified proving layer cannot be overstated. It is essential for accommodating the growing demand from L2 networks, zk applications, and coprocessors.

This collaboration not only eliminates the technical barriers traditionally associated with blockchain development but also opens the doors to new opportunities for Telegram users and developers to engage with blockchain technology in a meaningful way.

## What Are Ankr's New TON RPC Connections?

- Our TON RPCs (Remote Procedure Calls) connect your wallet, command-line interface, or decentralized applications with the TON blockchain. They act as a messenger or blockchain router that relays on-chain information between TON nodes, chains, and ultimately end-users so they can execute necessary tasks like transactions, populate wallet balances, fetch ownership information, and much more.
- TON RPC endpoints are a gateway for developers to interface directly with TON — a portal to communicate easily, remotely, and with no need to go through the DevOps of establishing their own TON nodes.
- Asphere is providing a geo-distributed TON RPC comprised of blockchain nodes running worldwide for incredibly low latency and reliable connections.

[Get started now with our TON RPC endpoints!](https://www.ankr.com/rpc/)

## How Do the TON RPCs Help Developers?

Building with TON is an excellent choice for creating high-performance and secure dApps, but requires access to the information on TON nodes to do so. Therefore, Ankr and Asphere RPC solves the following developer troubles:

**Eliminates complex node ops** - TON RPCs will completely remove the need for developers to set up their own TON nodes, removing hours of time spent building, calibrating, and fixing node issues.

**Grants access to advanced tools** -  Ankr’s [Premium RPC Plan](https://www.ankr.com/rpc/pricing/) instantly grants access to the best tools to build applications quickly, including:

- At least 90,000 TON req/minute

![agave.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/agave_e22c19793b.png)

Solana is ready for a significant update with the release of Agave v2.0, a new validator client developed by Anza that is poised to enhance the network's performance and security. Scheduled to go live on the Solana Mainnet-Beta in early October, this transition marks a big step forward for the Solana ecosystem. For developers utilizing Solana endpoints on Ankr's Web3 API services, it's important to stay informed and take any necessary steps to ensure a smooth transition during this update.

[Use Ankr’s Solana RPC →](https://www.ankr.com/rpc/solana/)

## What Is Agave 2.0?

Agave v2.0 is a major upgrade from the original Solana Labs validator client, bringing performance improvements while maintaining backward compatibility with existing Solana dApps. However, this update introduces several breaking changes, including RPC endpoint deprecations, SDK adjustments, and crate renaming, which could require updates to scripts and applications used by developers.

Moreover, the original Solana Labs GitHub repository will be archived, with all ongoing development shifting to Anza’s Agave client repository. This change underscores the broader effort to diversify Solana's validator clients, contributing to increased network resilience and reliability.

## Key Changes and What They Mean for Developers

Agave v2.0 introduces several changes that may require action from developers using Ankr's Solana RPC services:

### 1. Removed RPC Endpoints and Replacement Calls

Several RPC endpoints that were part of Agave v1.0 have been deprecated and will be removed in v2.0. Developers should update their code to use the new replacement calls provided by Agave v2.0.

Here's a quick overview of some important changes:

![calls.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/calls_fff13c2f98.png)

**Table and more info in [our docs](https://www.ankr.com/docs/whats-new/#removed-rpc-endpoints-and-sdk-items).**

These changes will ensure that your RPC interactions remain functional and optimized for the new Agave client, so it’s important to adjust your scripts before Agave v2.0 goes live.

### 2. SDK and Codebase Updates

Agave v2.0 also brings changes to the Solana SDK, removing support for Borsh v0.9 and deprecating several symbols in solana-sdk and solana-program. Developers are encouraged to switch to Borsh v1 or v0.10 and review any deprecated symbols in their code. The transition to Agave is a great opportunity to update your development environment to the latest standards, ensuring compatibility with future Solana innovations.

### 3. Renamed Crates

As Solana expands its validator client offerings, crate renaming has been introduced to differentiate Agave-related dependencies from those maintained by other teams. Below are some of the key crate renames:

![crates.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/crates_a9fc9b0b06.png)


**Table and more info in [our docs](https://www.ankr.com/docs/whats-new/#removed-rpc-endpoints-and-sdk-items).**

Make sure to update your dependencies to reference the new crate names to avoid any compatibility issues during the transition.

## Deprecated Validator Arguments

Agave v2.0 will also remove several deprecated validator arguments, some of which may impact your configurations. For example, the following commands will no longer be available:

![commands.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/commands_8e44645b6c.png)

**Table and more info in [our docs](https://www.ankr.com/docs/whats-new/#removed-rpc-endpoints-and-sdk-items).**

If you rely on any of these commands, you should review and update your validator configurations accordingly to prevent any disruptions when Agave v2.0 is deployed.

## Preparing for the Agave v2.0 Transition

The transition to Agave v2.0 will affect all validator operators and developers working with Solana. If you're using Ankr's RPC services, now is the time to review and update your apps to account for the removed RPC endpoints, renamed crates, and deprecations.

We recommend the following steps to prepare for this transition:

- **Audit your current RPC calls**: Identify any deprecated endpoints in your scripts or applications and update them to the new Agave v2.0 equivalents.
- **Update your SDK and dependencies**: Ensure you’re using the latest versions of the Solana SDK and update your dependencies to reference the new Agave-related crate names.
- **Revise validator configurations**: If you're operating a validator, review your arguments and configurations to remove any deprecated commands.

To check out the full list of changes, including more detailed technical documentation, please consult the Agave v2.0 [changelog](https://github.com/AnzaNetwork/Agave).

## Final Thoughts

The Agave v2.0 update is a testament to Solana’s commitment to continually improving its blockchain performance and security. While this transition introduces several changes for devs, it ultimately strengthens the network's infrastructure and opens the door for future innovations. By staying proactive and updating your scripts and apps ahead of the release, you can ensure that your experience on Solana remains seamless.

Ankr Staking was thrilled to announce our **liquid staking support for FLOW**, offering Flow blockchain enthusiasts the easiest way to make the most of their staking rewards. We’ve already seen an influx of **6,274,846 FLOW staked with Ankr**! Read on to see why the offering is making such big waves.

[Liquid stake FLOW now →](https://www.ankr.com/staking/stake/flow/)

## What is FLOW liquid staking?

By staking your FLOW tokens on Ankr’s platform, you receive **ankrFLOW** — a liquid staking token that offers more than just traditional staking rewards. With ankrFLOW, your rewards automatically grow every day as the tokens grow in value, and you can unlock additional earning opportunities across DeFi. Below you can see why staking your FLOW with Ankr Staking is the smartest move for maximizing your rewards.

## Why Choose Liquid Staking with Ankr Staking?

Staking FLOW tokens on Ankr's platform allows you to enjoy the benefits of liquid staking, an innovative solution that offers more flexibility in the ability to stake and unstake any time (as easy as a swap), while also providing more reward-earning opportunities for users.

Here are the main reasons to stake your FLOW tokens with Ankr Staking:

### **Earn Competitive FLOW Staking Rewards (10.65% APY)**

![flow staking.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/flow_staking_9b0ddf95aa.png)

Ankr Staking currently offers a highly competitive **10.65% APY** on your staked FLOW tokens. By holding ankrFLOW, you’ll receive these staking rewards **automatically** — no need to claim or reinvest earnings manually. This allows you to earn passively while your ankrFLOW balance continues to appreciate.

### **Boost Your Earnings With DeFi Opportunities**

![DeFi.png](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/De_Fi_27f3ea17ff.png)

While earning staking rewards, you can use your ankrFLOW tokens to unlock a second layer of rewards in the broader DeFi ecosystem. AnkrFLOW is already supported on popular DeFi platforms like [KittyPunch](https://swap.kittypunch.xyz/#/add/0x1b97100eA1D7126C4d60027e231EA4CB25314bdb/0xd3bF53DAC106A0290B0483EcBC89d40FcC961f3e) and [Trado](https://spot.trado.one/trade/add-liquidity/?token0=0x1b97100ea1d7126c4d60027e231ea4c[%E2%80%A6]0b0483ecbc89d40fcc961f3e&fee=3000&chainId=747&range=undefined%5C) DEXes, where you can contribute your ankrFLOW for additional rewards. This creates a powerful opportunity to **double-dip**: **earning both your FLOW staking rewards and extra returns from DeFi protocols at the same time.**

By exploring the [MORE Markets](https://app.more.markets/earn/0x8c921f740B0065C7cE28EB93c7056d92C4735E7b) lending protocol, users can stack their APY opportunities by staking FLOW on Ankr Staking to get ankrFLOW, and contributing ankrFLOW to the Super Flow Vault to earn more FLOW yield plus Flow Boxes. This allows users to loop their position and earn yield on yield in the Flow ecosystem.

### **Earn Even More With Flow Boxes**

![boxes.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/boxes_f6ab254216.jpg)

In addition to staking and DeFi rewards, staking FLOW with Ankr also gives you access to exclusive incentives through [Flow Community Rewards](https://flow.com/post/flow-rewards-season-1-is-here) Season 1. As a participant, you can earn **Flow Boxes** that unlock points toward even more prizes. This gamified rewards system allows you to engage with the Flow blockchain community while maximizing your staking experience.

### **Full Flexibility & Control**

With liquid staking, you are no longer locked into a staking period with your tokens. You retain the **flexibility** to trade your ankrFLOW tokens across various DeFi platforms. This makes liquid staking the perfect solution for investors looking to maximize their earning potential while keeping their assets flexible.

Blockchain developers increasingly seek the most scalable, efficient, and cost-effective platforms to build decentralized applications (dApps). Polygon, a leading Layer 2 Ethereum scaling solution, offers all this and more. By integrating with Ankr's API & RPC service, developers can seamlessly interact with the Polygon blockchain, taking advantage of faster, cheaper transactions without compromising on Ethereum’s core functionality. This article dives deep into Ankr’s Polygon API, exploring its benefits, use cases, and a step-by-step guide on how to get started.

[Access Ankr’s free Polygon APIs now → ](https://www.ankr.com/rpc/polygon/)

## What is Polygon and Why Choose It?
Polygon is a Layer 2 scaling solution for Ethereum, designed to increase throughput and reduce transaction costs by by offloading a significant portion of transactions from Ethereum mainnet. The Polygon Proof of Stake (PoS) network supports all existing Ethereum tooling and offers faster, cheaper transactions while maintaining compatibility with Ethereum’s smart contract infrastructure.

For developers, Polygon is the ideal environment to build and deploy scalable dApps, without dealing with Ethereum's sometimes slow and expensive transactions. Its native token, newly renamed from MATIC to POL, powers the network and is used for transaction fees, staking, and governance.

### Key Benefits of Polygon:
- **High throughput:** Polygon can process thousands of transactions per second (TPS), making it highly scalable.
- **Low costs:** Transaction fees on Polygon are a fraction of what you’d pay on the Ethereum mainnet.
- **Ethereum compatibility:** Developers can build on Polygon with the same Ethereum tools, making it easy to switch between the two.

-H 'Content-Type: application/json' \
-d '{
      "jsonrpc":"2.0",
      "method":"eth_blockNumber",
      "params": [],
      "id":1
    }'
```

**Response Example:**
```
{
  "jsonrpc":"2.0",
  "id":1,
  "result":"0x21fbd0f"
}
```
This simple request returns the current block number on the Polygon network.

## Advanced Scaling with Polygon zkEVM and Ankr
For projects needing even more security with low transaction costs, Polygon zkEVM is a zero-knowledge rollup (ZK-Rollup) solution that extends Ethereum's Layer 2 capabilities. It utilizes cryptographic proofs to bundle and validate transactions off-chain before publishing the proof on-chain, ensuring security and transparency.

```const { Connection, PublicKey } = require('@solana/web3.js');

async function getAccountBalance(publicKeyString) {
  const connection = new Connection('https://api.devnet.solana.com'); // Replace with your desired cluster's RPC endpoint

  try {
    const publicKey = new PublicKey(publicKeyString);
    const accountInfo = await connection.getAccountInfo(publicKey);

    if (accountInfo) {
      const balanceInLamports = accountInfo.lamports;
      const balanceInSOL = balanceInLamports / 1000000000;
      console.log(`Balance: ${balanceInSOL} SOL`);
    } else {
      co
nsole.error('Account not found.');
    }
  } catch (error) {
    console.error('Error fetching account balance:', error);
  }
}

// Replace 'your_public_key' with the actual public key of the account you want to check
getAccountBalance('your_public_key');
```


## Python (Solana Py):
**Python**

```from solana.rpc.api import Client

async def get_block_height():
    client = Client("https://api.devnet.solana.com")  # Replace with your desired cluster's RPC endpoint

    try:
        block_height = await client.get_block_height()
        print("Block Height:", block_height)
    except Exception as e:
        print("Error fetching block height:", e)

# Example usage:
get_block_height()
```

## Rust (Solana Rust):
**Rust**

```use solana_client::rpc_client::RpcClient;

async fn get_fee_rate() -> Result<(), Box<dyn std::error::Error>> {
    let client = RpcClient::new("https://api.devnet.solana.com"); // Replace with your desired cluster's RPC endpoint

    let fee_rate = client.get_fee_rate().await?;
    println!("Fee Rate: {}", fee_rate);

    Ok(())
}

// Example usage:
get_fee_rate().await?;
```

## Important Considerations Solana RPC URLs:
- **Rate Limits:** Be mindful of rate limits imposed by public RPC providers.
- **Security**: Always double-check the URLs you use to prevent phishing attacks.
