An Overview of Blockchain Indexing Protocol

An Overview of Blockchain Indexing Protocol

Blockchain is a thriving technology that is gaining significant recognition from a variety of sectors in the marketplace. It was first recognized in 2008 for being the primary technology behind Bitcoin. With time, however, the applications of Blockchain aren’t limited to just one purpose for financial transactions but a variety of.

With the huge number of cryptographic records stored on Blockchain, it is difficult to sort and locate information on the platform that is decentralized.

To accomplish this, you have to make a key-value index using a distributed Redis database to keep the data that you get from the Blockchain platform.

In this case, for instance, you use Ethereum by means of an interface Ethereum offers via an application called web3 which allows access and retrieval of data from the structure of its own.

In the case of a distributed ledger like the Blockchain, the information of an entity could be scattered across the entire system the ledger without an index which makes it difficult to find the data.

This article focuses on how to use the Blockchain Indexing Protocol and its significance with regard to Blockchain Queries.

As blockchain technology gets more popular and used to facilitate transactions in a decentralized manner to facilitate real-world applications The need to be able to query the information stored on the blockchain is increasing. Additionally, because of the blockchain’s time-ordered structure, linked data is spread across a variety of blocks and there is no mechanism built-in to recognize and categorize or search for it.

As an immutable and open network, which no one person controls or manages and also having a consensus mechanism to verify transactions and verify the authenticity of transactions written on it Blockchain opens the door to an array of applications. It also has prompted tech developers to think about different methods to increase the speed of the process of transactions. These techniques will better suit certain situations where the use of proof of work isn’t the most appropriate choice.

A blockchain, as a distributed ledger, stores data. It is possible that the transaction data in the chain needs to be accessed. This could happen with the creation of an electronic blockchain that stores the information on electronic healthcare records. There’s a chance that we’ll have access to a particular patient’s history of treatment over time.

Blockchain technology provides the benefits of decentralization as well as tamper resistance which allows the storage of data in a secure manner. However, the current blockchain technology does not have the best data management capabilities and allows only traversal queries by using transactions hashes as variables. The method of querying that is that is based on the trace chain (ATTC) increases the efficiency of queries based on the account’s transactions in the past. The effectiveness of searching for accounts that have long chains of transactions however has not been significantly increased.

Now we know how Blockchain indexing is vital to index queries that are on the blockchain. Let’s look at the mechanisms of blockchain indexing by using its Blockchain Indexing Protocol. Blockchain Indexing Protocol is a distributed indexing system to organize blockchain data. The protocol is utilized by applications to search open APIs to obtain information that is stored on the blockchain networks. Developers can use blockchain indexing to build servers that operate on the public infrastructure. It allows the search of data that is not accessible directly.

The indexing protocol arranges all data stored on the Blockchain which allows developers to manage their front-end functions more effectively. One of the most prominent causes for the Blockchain Indexing Protocol is The Graph that implements an indexing protocol to facilitate the accessibility of apps that are decentralized through APIs that are open and public, referred to as subgraphs. The graph’s indexing tool can be used to find and retrieve data from Ethereum similar to what other indexing tools can do for traditional databases that are centralized.

The Graph knows what to look for it is and how to index Ethereum information using subgraph manifests. Subgraph information describes the smart contracts that need to be monitored for a particular subgraph as well as the events that must be monitored within these contracts, as well as how the event information is to be converted into data which The Graph will save in its database.

Once a subgraph manifest has been made, you can make use of the graph CLI to store it to IPFS and tell the indexer to start indexing the data for the subgraph. The steps Flow Blockchain takes to index the queries are as below:

Decentralized applications contribute information to Ethereum through an electronic smart contract.

When processing the transaction the smart contract creates several events.

Graph Node is always scanning Ethereum for new blocks as well as the information they could provide to your subgraph.

Graph Node searches these blocks for Ethereum events that relate to your subgraph. It then implements the mapping handlers that you’ve specified.

The mapping is a WASM module responsible for generating or updating the data entities the Graph Node holds in response to Ethereum events.

The decentralized application makes use of Graph Node’s GraphQL endpoint to query the node to find data that is indexed by the Blockchain.

This Graph Node then converts the GraphQL queries into SQL queries to its underlying data store to access the data using the store’s indexing capabilities.

The decentralized software provides this information to users through a useful UI which they can then utilize to make brand new Ethereum transactions. The process continues.

Blockchain records information in a distributed manner which makes it difficult to locate the data. Blockchain Indexing Protocol plays an important role in the procedure that is Blockchain Data Query. Users can use specific data according to the search which is then filtered by blockchain indexing.
