Amazon Web Services to help get the first billion users into blockchain game

CEO of Dashbird. Everyone and their pets are starting an NFT project. Some people got rich from using NFTs; others did not. Some say it's the savior that will rip the power away from big corporations and give it back to the creators; others say it's just a giant pyramid scheme.

I don't know how things will play out, if blockchains will be the next big thing, fueled by the NFT hype, or if it will fizzle out like so many other technologies before it. But a question I got asked lately was, how does this precisely fit in with AWS and serverless technology? That's why I thought, let's ride the hype train and write an article about NFTs and serverless technology!

You will need such a service if you don't want to rely on nodes of third parties, like Infura or Alchemy. These nodes can be seen as the bridge between on-chain services and off-chain services. So you should use it to make it safe that your nodes don't go down when the third party gets bankrupt or if you managed to get exorbitant bills from a third party service.

It's used if you need the immutability of a blockchain, but without everything decentralized, that comes with it.

The nodes that make up the decentralized system Ethereum can be seen as servers in a classical setup or the databases and functions in a serverless design. They mine new blocks or validate transactions; they also execute the software that is known as a smart contract.

This means you need to connect to a node to access the Ethereum blockchain. In this article we aren't focusing on nodes, so AMB doesn't interest us here.

We want to implement a client that asks a node for data that's stored on the blockchain. So, our example will be located off-chain. It will consist of a Lambda function called every hour and an S3 bucket to store data off-chain. We will use JavaScript and the Ethers. The data we will check is the supply of NFTs a smart contract has issued. Since many of the smart contracts on the Ethererum blockchain have well-defined interfaces, we can write a function that just needs a contract address to do its work.

Usually, AWS is seen as a competition to Ethereum because "Ethereum is just another way to build backends," but I think they can work together. Transactions on the blockchain are expensive, so some data and calculations could be outsourced to an off-chain system like AWS Lambda. To connect a non-Ethereum off-chain system with an Etherum smart contract on-chain , it must connect to a node.

We already learned that AWS offers rather expensive nodes we could use, but there are many services out there that can be used for free. These services have harsh limits, but for this example, they should suffice. Usually, transactions on the blockchain cost gas, but we will only call a function marked as view. This way, the node we connect to can simply read the data from its local blockchain copy, no transactions, and in turn, neither a wallet nor gas is needed.

A bucket and a Lambda function. The bucket name and the address of the smart contract are passed to the Lambda function via environment variables. The first line defines the Application Binary Interface of the smart contract we want to call.

It's just an array of strings that make up the method signatures of that contract. I didn't define all the contract methods because I will just call one of them anyway. In the function body, I get the default provider from Ethers. In this example, the function is only executed once an hour, so it won't hit the limits. Still, in a production system that might access a node provider more often, you should sign up for an Ethereum gateway service like Infura or Alchemy.

Then I set up the contract with the correct ABI, address, and provider. The provider makes sure we are connected to the proper chain there are test chains for Ethereum, we don't want to communicate to those.

The ABI tells Ethers. And finally, the contract's address so Ethers. If you moved some of your calculations off-chain and into AWS Lambda, you can monitor them with Dashbird like every other serverless system you build on AWS. No additional setup is needed. We can set up alarms for our NFT checker and get notified if things fail.

In Figure 1, we see the general information Dashbird gives us about a Lambda function. This just resembles a few test invocations, but we can already see some interesting things. The executions were all free of charge and they fit snuggly into the smallest memory configuration.

That's good to know. But if we look at the Duration tab in Figure 2, we see that our function has varying runtimes. The function took anything from under 1 second to up to 3 seconds to do its work. With the default Lambda invocation timeout of 3, milliseconds, our function is at high risk to be shut down prematurely.

Especially, since it's only called once every hour, it will have a cold-start every time. We can use the insight gathered by Dashbird to update our Lambda function definition with a more generous timeout, so it won't accidentally crash in the future.

This small example application outlined how serverless technology can be used in tandem with blockchains. Lambda functions are cheaper and faster than blockchain transactions, so they lend themselves for non-critical calculations that don't have to be tracked by a blockchain. This example was straightforward and somewhat contrived, but doing automated work that depends on the state of a blockchain is an actual use case.

And, through customer exemplars, build greater understanding of when you need which capabilities in particular trading on a superset of characteristics that takes in immutability, cryptographic assurance for tamper-evident operation, auditability, consensus, etc. Or perhaps the incumbent authority is so much the lb gorilla that nobody who wants to continue to do business in that setting has the clout to overturn their particular status quo. So they put up with it remaining in situ as an acceptable cost of doing business. However, even gorillas sometimes find it desirable to make the existing system more inherently trustable, accountable, and auditable even if all concerned do still have to rely on systems ultimately operated by that single player, rather than each having a true decentralised stake in the proceedings.

Blockchain enables applications where multiple parties can record transactions without the need for a trusted, central authority to ensure that transactions are verified and secure by establishing a peer-to-peer network where each participant in the network has access to a shared ledger where transactions are recorded. These transactions are, by design, immutable and independently verifiable, which makes the technology especially attractive for accountants and firms which handle sensitive financial information, usually at a high volume.

The announcement of blockchain services at AWS re:Invent came as a surprise, but the cloud giant believes it has the right product for the right market at the right time. The company hadn't shown much interest in the technology before and Jassy said it was because "it hadn't seen any examples in production that couldn't be solved by a database". Looking at blockchain itself, which is formed from a perpetual list of records, called blocks, linked using cryptography and contains timestamps and transaction data, there are not yet masses of innovative use cases and its original purpose, underpinning cryptocurrency, is not the best example of it as Bitcoin continues to sink. Then there's the empty hype, such as the Hdac advert that played out during this year's world cup, which offered smart home technology powered by the magic of blockchain, without much explanation of how it actually worked. That's a really important aspect, we don't just build science projects, we're really building the things the customers ask us for. For Moyer, these large financial organisations supported its work with blockchain.

E-commerce giant Amazon has unveiled a new solution that allows users of its cloud computing platform to create and deploy secure blockchain networks. Blockchain Templates is offered as an additional service for Amazon Web Services AWS and is powered by a range of open-source frameworks. The service is positioned as a quick and easy way for companies and individuals to set up their own blockchain networks for a variety of purposes. With AWS Blockchain Templates, users are able to easily integrate Ethereum and Hyperledger Fabric frameworks into their cloud infrastructures, says the company.
