Fast and reliable connection to OP node and explorer. Connecting to the OP node via NOWNodes lets you focus on your blockchain project without worrying.
Optimism is essentially a Layer-2 project that aims to scale Ethereum through the process of providing quick and cheap transactions by leveraging the power of Optimistic Rollups.
Optimistic Rollups are utilized as a means of publishing transactions to the blockchain without needing to execute them on top of the Ethereum Layer-1 blockchain network. What this means is that any transactions that are made on top of Optimism get pushed internally and are finalized at the point in time when they get back to the Ethereum mainchain.
This means that the blockchain transaction or gas fee which is required to be paid comes down to only one transaction instead of hundreds or thousands of transactions. These transactions are assumed to be valid until they are proven false, and there is a time window during which potentially invalid transactions can be challenged by submitting a "fraud-proof" and running the computation with reference to available state data.
Despite the existence of many other cryptocurrencies, RSK has a lot of advantages and here are just a couple of them.
Optimism is built on top of Ethereum, which means that it can still leverage its compatibility, accessibility as well as security and can scale it to process a lot more transactions than it would by default.
The Ethereum network is slow and, as such, cannot really conduct thousands of transactions without incurring high gas fees. The main way through which rollups work is by rolling up or bundling the data surrounding hundreds of transactions, which can be non-fungible token (NFT) mints, token swaps, or just about any other transaction, within a single transaction on the Ethereum mainnet at Layer-1.
the OP cryptocurrency powers the Optimism network and is responsible for protocol upgrades, network parameters, treasury funds, and project incentives. It is the governance and incentive token within the network.
If you are a blockchain developer or decentralized application (dApp) developer, or simply want to write smart contracts, or even bundle thousands of transactions, then connecting to an Optimism node is essential so you can get access to all of the valuable blockchain data.
It has never been easier to access the Optimism network’s data than it is today, especially through the utilization of the NOWNodes blockchain as a service provider.
By leveraging the power of the blockchain node, you can put your focus on the development of your specific products, services, or anything else that you are curious about creating with the network due to its utility.
In other words, by connecting to a blockchain node, you can browse its data in a similar way as you would, for example, using a search engine such as Google to look up websites.
However, in the case of the NOWNodes blockchain node, you will need to head over to the official documentation to get a clear view of all of the commands you can use.
Remember that NOWNodes does not just give you access to a single node, but alongside Optimism (OP), you can access 57 other nodes, and you can find the official list here if you are curious about all of the available nodes.
In order to get started, all you have to do is visit the official NOWNodes, after which you can enter your email address, and click on the “GET FREE API KEY” button, which will provide you with everything you need to have in order to connect.
The Optimism (OP) block explorer will allow you to synchronize with the blockchain and give you all of the data that you require from it in real-time.
This can include data surrounding block height, wallet addresses, transaction data, balance history tickers list, or anything else that you need, all of which will be valuable throughout your development process.
What this means is that you can establish a secure RPC connection that utilizes the API key given to you, and each node has an uptime of 99.95%. There are numerous plans available at NOWNodes, and the free plan will give you access to 5,000 free requests per day, while the Standard, Pro, and VIP plans all have additional benefits and use cases if you require them.
