Getting Ahead: Practical Steps to Start Storing Data On-Chain was originally published in Layer4 on Medium, where people are continuing the conversation by highlighting and responding to this story.

Now, let’s dive deeper into what you need to know to make an informed decision about integrating blockchain into your data storage strategy.

Encryption and Data Privacy
A common misconception is that blockchain data is encrypted by default, but this is not the case. Encryption transforms data into a coded format that can only be deciphered with a specific key, ensuring only authorized parties can access the information. To enhance security, data can be encrypted before being stored on-chain. This approach ensures that even though public blockchains are transparent and the data is publicly accessible, only those with the decryption key can read the encrypted data. This level of security is crucial for protecting sensitive information, such as financial records or personal details.

On the other hand, cryptography is a broader field encompassing various techniques used to secure data and transactions on the blockchain. While encryption is a method within cryptography focused on converting data into a secure format, cryptography also includes hashing, digital signatures, and other mechanisms that ensure the integrity, authenticity, and confidentiality of blockchain transactions. Together, encryption and cryptography ensure that blockchain data remains tamper-proof and secure, maintaining the highest standards of data protection.

If data privacy is a requirement, ensure you choose a blockchain integration solution that supports advanced encryption techniques and privacy-focused features.

Scalability and Performance
While early blockchains faced scalability issues, recent advancements have significantly improved performance. Techniques like sharding and off-chain transactions enable blockchains to handle larger volumes of data efficiently. Sharding divides the blockchain into smaller, more manageable pieces, allowing for parallel processing and increasing the system’s overall capacity. Side-chain transactions, which involve moving certain transactions outside the main blockchain, can also improve scalability by reducing the load on the main chain. These advancements are making blockchain more viable for large-scale data storage and transaction processing.

However, it is not yet perfect. Handling high-volume transactions to store data in chronological order often requires services that offer additional scaling solutions and infrastructure support. Many blockchain solutions still rely on specialized auxiliary systems to manage data effectively, ensuring that the integrity and order of transactions are maintained. Furthermore, integrating these solutions can be complex and necessitate significant technical expertise and resources. As the technology continues to evolve, ongoing improvements and innovations are expected to address these challenges, making blockchain an even more robust solution for data storage and management.

Consider if high throughput, transaction ordering or a combination of both is required when evaluating your blockchain solution

Interoperability
While blockchain technology holds great promise, integrating it with existing systems comes with significant challenges. The most commonly cited barriers to blockchain technology integration are the complexity of implementation and the associated costs. Integrating blockchain requires a high level of technical expertise, leading to substantial upfront investments in time, talent, and resources. Businesses often need to overhaul or update their current infrastructure to accommodate the unique requirements of blockchain technology. This can involve reconfiguring existing systems, ensuring compatibility with blockchain protocols, and training staff to manage and maintain the new technology. These initial hurdles can be limiting and require careful planning and allocation of resources.

Technical Insights: Implementing Blockchain for Data Storage was originally published in Layer4 on Medium, where people are continuing the conversation by highlighting and responding to this story.

Building on last week’s introduction, let’s explore some specific advantages of using blockchain for data storage. The benefits of blockchain go beyond just security and transparency, offering a range of advantages that can transform business operations and drive efficiency.

TLDR; Blockchain ensures data integrity, reduces costs by eliminating intermediaries, provides a “pay once, store forever” solution and improves data management and collaboration through a unified, immutable ledger.

We all appreciate when things are accurate, cost-effective, and efficient right? That’s exactly what blockchain offers. Let’s dive in and explore how blockchain can help achieve this.

One of the most significant advantages of blockchain is its ability to ensure data integrity. Blockchain’s immutable (unchangeable) ledger ensures that data remains consistent and accurate. Once data is recorded on the blockchain, it cannot be altered or deleted. This immutability is crucial for maintaining a single source of truth, reducing the risk of errors and discrepancies. For businesses, this means they can rely on the accuracy and consistency of their data, improving decision-making and operational efficiency.

By eliminating the need for intermediaries and reducing the costs associated with data reconciliation, blockchain can lead to significant cost savings. Traditional data storage systems often require multiple layers of verification and processing, adding to the costs and complexity. Blockchain, on the other hand, allows data to be stored directly on-chain, reducing the need for intermediaries and associated costs to prove its accuracy. Over time, these savings can add up, making blockchain a cost-effective solution for businesses of all sizes. Additionally, the automation of processes through smart contracts can further reduce operational costs and improve efficiency. With blockchain’s “pay once, store forever” model, businesses can store data immutably without recurring storage costs, further enhancing cost-effectiveness.

Blockchain also simplifies data management by providing a unified structure that all parties can access and contribute towards. This ease of data sharing enhances collaboration and streamlines operations. In a traditional setup, data silos can create inefficiencies and hinder collaboration. With blockchain, all relevant parties have access to the same data, ensuring everyone is on the same page. This unified approach can improve coordination and reduce delays, particularly in complex supply chains and multi-party business processes.

Now that we have a better understanding of blockchain’s benefits, let’s look at how companies across various sectors leverage blockchain for data storage:

In supply chain management, it provides end-to-end traceability. For example, blockchain can track a product’s journey from production to delivery, ensuring it is authentic and has not been tampered with. This transparency can enhance trust and accountability.

The real estate industry utilizes blockchain to simplify property transactions by providing a transparent and secure record of property ownership and transaction history. This can reduce fraud and streamline the buying and selling process.

Even governments utilize blockchain to ensure transparency and accountability in public records, reducing the risk of corruption and enhancing trust in public institutions.

Blockchain is not just a buzzword; it’s a transformative technology that offers real, tangible benefits. Blockchain can significantly improve business operations and drive competitive advantage by enhancing data integrity, reducing costs, and improving data management.

Join us next week as we delve into the technical aspects and practical considerations of implementing blockchain for data storage, and learn how you can leverage this technology to enhance your business operations.

Why Storing Data on a Blockchain is Advantageous for Businesses was originally published in Layer4 on Medium, where people are continuing the conversation by highlighting and responding to this story.

But what exactly is blockchain, and why should you consider it for your data storage needs?

At the core, blockchain is a distributed ledger that records transactions across many computers so that the record cannot be altered retroactively. This ensures that the data’s authenticity remains intact. One of the key features of blockchain is its decentralized nature. Unlike traditional databases that rely on a central authority, blockchain is maintained by a network of nodes (computers) that work together to validate and record transactions. This decentralized approach enhances security and reduces the risk of a single point of failure.

Let’s explore some of the key benefits of blockchain as a solution for data security.

Enhanced Security
Blockchain uses advanced cryptographic techniques to secure data. Each transaction is recorded in a block and linked to the previous one, forming a chain that is immutable (unchangeable). This means once data is written, it cannot be altered or deleted without the consensus of the network (the majority of the network agrees on the change — this is why decentralization matters), providing near-impenetrable protection against tampering and unauthorized access.

Transparency and Trust
All transactions on a blockchain are transparent and visible to all participants in the network. This transparency promotes trust and accountability, as every participant can verify and audit the transactions independently. Data breaches and fraud are common, hence the transparency offered by blockchain can significantly enhance trust among stakeholders. For example, in financial transactions, blockchain can provide a clear and tamper-proof record of all transactions, reducing the risk of fraud.

🤔 You might be wondering, that’s great, but what are some of the real-world applications?

Many industries are already leveraging blockchain for data security and transparency. For instance, in finance, blockchain is used to secure transactions and reduce fraud. Blockchain’s transparency ensures that all financial transactions are traceable and auditable, reducing the risk of fraud. Healthcare software providers are leveraging blockchain to ensure the integrity of patient records. By storing medical records on a blockchain, healthcare providers can rest assured that patient data is accurate, secure, and accessible only to authorized personnel. The supply chain sector can arguably be considered an “early adopter” of blockchain to provide traceability and accountability from production to delivery. This transparency ensures that products are authentic and have not been tampered with during transit.

As we dive deeper into the advantages of blockchain over the next few weeks, you’ll see why it’s becoming an essential tool for secure and efficient data management. Stay tuned for next week’s post, where we will explore the specific advantages of using blockchain for data storage and how it can transform your business operations.

Understanding Blockchain as a Solution for Data Security was originally published in Layer4 on Medium, where people are continuing the conversation by highlighting and responding to this story.

Storing data in a traditional centralized database is susceptible to manipulation and, therefore, corruption. To make your data more trustworthy, you want to store it on a blockchain so that it is permanent, incorruptible and auditable in an unprecedented and transparent way.

Assuming you agree with the benefits of persisting your off-chain data on-chain, does that mean you now need to become a blockchain expert to reap the benefits? With Layer4, you don’t.

When would you not want to store data on-chain?

Data on the blockchain is transparent by default. When people talk about the security of data on-chain, they are not referring to the data being private or secure from being accessed. The security of on-chain data lies in the fact that it is provably unaltered. Data can not be changed without leaving a trace, or manipulated without corrupting the whole network.

Understanding the blockchain’s public nature, it is clear that you do not want to store any sensitive data unencrypted on-chain.

Possible use cases

The use cases for on-chain data are vast. In the financial sector, the accuracy and transparency of records like invoices can be ensured. The tracking of product movements using IoT devices for the supply chain can be enhanced. Other uses include safeguarding legal documents from unauthorized alterations, proving ownership and provenance of intellectual property such as patents, and facilitating detailed audit trails for regulatory compliance and risk management.

Before you record data on-chain

Make sure you register for a free account on the Layer4 web app.

Once you have registered, a workspace will be created for you. You are now ready to create a bucket for your on-chain records.

Record data via the web app

Bucket Creation

To record data on-chain, you need to have a smart contract running on your desired blockchain network — don’t worry, Layer4 deploys the contract for you. In Layer4, this is done by creating a bucket. Each bucket is associated with a specific type of smart contract. You want to choose the “Store data on-chain” custom contract.

Ensure you create your bucket for the blockchain network you prefer.

Give your bucket a unique name or go with the auto-generated option, and click “Create”.

Once your smart contract is ready, it will clearly show that it has been deployed. You can now create your first record.

Record Creation

From the bucket dashboard of your newly created bucket, click the “+” icon button on the “Records” card. You will be greeted with a short form with which you can add your first record.

The only required field is to add the Data you want to record.

As of May 2024, a limit of 512 bytes exists on the Data payload. It is generally recommended to upload and reference a file in the Data field if you need larger payloads. Whatever you add to this field is what will ultimately be stored on-chain.

Let’s cover the other available fields briefly.

Within your bucket, records are organised into Segments. All buckets come with a default segment. You can add as many segments as you need for your use case. Segments aren’t stored on-chain and only serve as an organizational aid for your data within Layer4.

Add up to 10 optional Files to your record. Files are uploaded to the decentralized and globally distributed IPFS network and can be referenced in the Data payload. To reference a file, you add a special placeholder tag that the platform interpolates after the file is uploaded. Reference the URI to the file with the {{fileUri:0}} tag where 0 is the index of the file in the list of files. To insert the file’s unique content hash, you use the {{fileHash:2}} tag. Again, index 2 here refers to the 3rd file in the files list.

To richly present the data, you can optionally specify the Content Type of the Data payload. For instance, if your payload is JSON data, you can set it to application/json. If you’re unsure, leave it as the default text/plain type.

Once you’re happy with your form, double-check that you have enough credits to fund the record, and click the “Request” button. From here, Layer4 will take care of getting your data on-chain.

Viewing the record

A few seconds later, you should see your finalized record in the records table within the app.

Click on the icon at the start of the row for your record to view its details. From the details panel, you see exactly what was stored on-chain, plus any relevant blockchain transaction details, files and other metadata.

Congrats, you’ve stored your first off-chain data on-chain. That was easy!

If you are looking to store larger volumes of data on-chain, doing it manually via the form is not ideal. For that, let’s look at creating a record via the REST API instead.

Record data via the API

If you don’t have a bucket yet, reference the section above to do that first.

Create an API key

To use the Layer4 API, you need an API key, which you also create in the web app.

From the “API Keys” card on the bucket’s dashboard, click the “+” icon to create a new key. Give your key a name that will help you distinguish it from other keys. A good practice is to name the key based on where it will be used. Ensure the key has the appropriate scopes (read and/or write) for your use case and select when the key should expire.

We encourage regular rotation of your API keys.

Make sure you copy and store the provided API key in a safe place. It can’t be retrieved once it has been created. You will have to create a new key when you want to replace it.

Confirm you’ve backed up the key and finally click the “Create” button.

You are now ready to start making API requests.

Pick your endpoint

It is important to know that Layer4 distinguishes between Records and Record Requests. A Record is the actual entry that has settled on the blockchain. A Record Request, on the other hand, is an entity created before it eventually settles as a Record.

The same applies for Tokens and Token Requests but that is for another article.

Record Requests will be processed asynchronously in the order received. Use the Record Request endpoints when you can fire and forget the request without needing to wait for the Record to settle on the underlying blockchain. Also, if the order of the events is important for auditability, these endpoints guarantee the order will be preserved. Since these requests are processed sequentially, it will take longer to persist on-chain under high load.

If you need to wait for the Record response, you should use the synchronousRecords endpoints. When you use the Records endpoints, the order in which requests are made to the platform becomes fully your responsibility. Bear in mind that these synchronous endpoints will naturally be slower to respond since they need to wait for the transactions to be included on the underlying blockchain. Confirmation times differ vastly from network to network.

With that out of the way, let’s create our first record asynchronously via aRecord Request.

Please take note of your bucket ID and API key and replace them in the requests below. We will use the cURL command in our examples, since it is the most universal, but feel free to translate this to your programming language’s preferred HTTP library.

In my case the bucket ID is demo-data-storage and the API key is bk_test_iiDYquj4MKUkjpvq.

curl -H 'Content-Type: application/json' \
  -H 'x-api-key: bk_test_iiDYquj4MKUkjpvq' \
  -d '{"segmentId": "default", "contentType": "text/plain", "data": "Data recorded via async API endpoint"}' \
  -X POST https://www.layer4.app/api/v1/buckets/demo-data-storage/async/records

Take note that this is the /async/ API, so it will return a Record Request entry.

If everything was successful, your response should look similar to this:

{
  "data": {
    "id": "663391a0ff10483f4272c849",
    "createdAt": "2024-05-02T13:14:08.524Z",
    "updatedAt": "2024-05-02T13:14:08.524Z",
    "type": "CREATE",
    "status": "REQUESTED",
    "payload": {
      "bucketId": "demo-data-storage",
      "segmentId": "default",
      "contentType": "text/plain",
      "data": "Data recorded via async API endpoint"
    },
    "bucketId": "demo-data-storage",
    "recordId": null,
    "files": [
      
    ]
  },
  "statusCode": 201,
  "success": true
}

All Layer4 REST API responses adhere to the following format:

{
  "data": {},
  "statusCode": 201,
  "success": true
}

• The data field contains the response data.
• The statusCode field displays the HTTP status code.
• The success field indicates whether the request was successful.

We can query for this particular Record Request’s status using the following request:

curl -H 'Content-Type: application/json' \
  -H 'x-api-key: bk_test_iiDYquj4MKUkjpvq' \
  -X GET https://www.layer4.app/api/v1/buckets/demo-data-storage/record-requests/663391a0ff10483f4272c849

Because the Record Request has since settled on the underlying network, the status is now CONFIRMED and you can see the recordId in the response.

{
  "data": {
    "id": "663391a0ff10483f4272c849",
    "createdAt": "2024-05-02T13:14:08.524Z",
    "updatedAt": "2024-05-02T13:14:22.319Z",
    "type": "CREATE",
    "status": "CONFIRMED",
    "payload": {
      "bucketId": "demo-data-storage",
      "segmentId": "default",
      "contentType": "text/plain",
      "data": "Data recorded via async API endpoint"
    },
    "bucketId": "demo-data-storage",
    "recordId": "yEBODz1gK0ggJyZT",
    "files": [
      
    ]
  },
  "statusCode": 200,
  "success": true
}

We can next query for the related Record using the returned recordId:

curl -H 'Content-Type: application/json' \
  -H 'x-api-key: bk_test_iiDYquj4MKUkjpvq' \
  -X GET https://www.layer4.app/api/v1/buckets/demo-data-storage/records/yEBODz1gK0ggJyZT

This request should respond with a JSON object similar to this:

{
  "data": {
    "createdAt": "2024-05-02T13:14:22.319Z",
    "updatedAt": "2024-05-02T13:14:22.319Z",
    "segmentId": "default",
    "chain": "POLYGON_AMOY",
    "contentType": "text/plain",
    "recordId": "yEBODz1gK0ggJyZT",
    "data": "Data recorded via async API endpoint",
    "bucketId": "demo-data-storage",
    "transactionHashes": [
      "0x162fe22c8128d97646323ac9c929fc6d0d53c37457f5d4032f46136bf6981031"
    ],
    "contractId": "66337c7cb83f2f2ff1939cb0",
    "files": []
  },
  "statusCode": 200,
  "success": true
}

We can confirm that this record exists on the blockchain.

Since I deployed my Data Storage contract to the Polygon Amoy Testnet, we can find the transaction on the Polygon Amoy block explorer using the returned transactionHashes.

Polygon PoS Chain Amoy Transaction Hash (Txhash) Details | PolygonScan

Or, you can now see this same record in the Layer4 web app.

This concludes the full asynchronous flow for creating Records.

Before we wrap up, let’s quickly look at how you would use the synchronous Records endpoint to create a record.

curl -H 'Content-Type: application/json' \
  -H 'x-api-key: bk_test_iiDYquj4MKUkjpvq' \
  -d '{"segmentId": "default", "contentType": "text/plain", "data": "Data recorded via sync API endpoint"}' \
  -X POST https://www.layer4.app/api/v1/buckets/demo-data-storage/records

Note that this endpoint does not have the /async/ path segment.

This request directly responds with a Record (as opposed to a Record Request) as we would expect.

{
  "data": {
    "createdAt": "2024-05-02T14:31:02.368Z",
    "updatedAt": "2024-05-02T14:31:02.368Z",
    "segmentId": "default",
    "chain": "POLYGON_AMOY",
    "contentType": "text/plain",
    "recordId": "hxFAGd9U92Q0kyZC",
    "data": "Data recorded via sync API endpoint",
    "bucketId": "demo-data-storage",
    "transactionHashes": [
      "0x55afd17a048b036b6000ce6095eaacba21fdadf09d4b76f3d53dda62fce4e215"
    ],
    "contractId": "66337c7cb83f2f2ff1939cb0"
  },
  "statusCode": 201,
  "success": true
}

Finally, let’s query for all the Records we’ve created for our bucket.

curl -H 'Content-Type: application/json' \
  -H 'x-api-key: bk_test_iiDYquj4MKUkjpvq' \
  -X GET https://www.layer4.app/api/v1/buckets/demo-data-storage/records

This request responds with the 3 Records we’ve created in this article:

• one directly in the web app
• one using the asynchronous endpoint
• one using the synchronous endpoint

  "data": {
    "records": [
      {
        "createdAt": "2024-05-02T14:31:02.368Z",
