What is blockchain JSON?
JSON-RPC is a data exchange protocol that allows a client (for example: a blockchain explorer) to communicate to a server (your local blockchain node) by issuing commands and listening to responses.
® Blockchain technology is a software; a protocol for the secure. transfer of unique instances of value (e.g. money, property, contracts, and identity credentials) via the internet without. requiring a third-party intermediary such as a bank or government. ® Email over IP, Voice over IP, Money over IP.
Getting the xpub in Ledger Live
Go to the account to get the xpub for and click on the wrench icon. Expand the Advanced logs in the Edit account window that appears. There you can copy the xpub which looks like a long alphanumeric string beginning with xpub...
A zpub is a form of extended public key (xpub) which follows an additional standard defined in BIP 84. Xpubs, ypubs, and zpubs all allow a wallet to generate a deterministic tree of public keys, but each form of extended public key instructs a wallet to derive different address types.
- Find the "Settings" page located bottom right.
- Then click "Wallets".

API's are used for software applications to send and receive data. API's can also connect one program to another, to share functionality. In order to connect to or communicate with another API, an API key is necessary.
CoinMarketCap API
CoinMarketCap is commonly known to be the go-to for checking cryptocurrencies and token prices. CoinMarketCap provides API levels for individual users and businesses. The free plan has limits on the number of API calls you can make per month.
But if you want to query the bitcoin blockchain locally, you'll need to download the 120+GB blockchain and then write up a custom script to consume the data manually to do what you need. Time intensive if you are willing to invest in it. Otherwise best to use publicly available stats and data and work off of that.
How do I get my Etherscan API key?
On the Etherscan user dashboard, you can select “API-KEYs” from the left-hand side column. A pop up as below will appear when you click on “Create a new API-KEY token”. You can assign a name to the particular API key you intended to create.
Creating Your API Key
After you've selected your preferred permissions, click “Create API Key” at the bottom of the page. Coinbase Pro will then walk you through a two-factor authorization process and then give you your API Passphrase, API Key, and API Secret.
An API Secret, also referred to as API Private Key is simply a password used in combination with an API Key. You can think of the API Passphrase as a second password you need to enter to establish a connection between the two applications. Coinbase Pro implements this as an extra measure of authentication.

If you are solo mining, then you need the entire blockchain since each block you mine references the hash code of the last block in the chain. If you don't have the last block yet, then the network will reject your mined blocks since there will already be later blocks in the blockchain.

Web3 is a collection of JS libraries that lets you interact with an Ethereum node remotely or locally. Simply, it provides us with an API to use so we can easily work with the blockchain. Web3 works as a wrapper for JSON RPC to connect to a remote or local Ethereum node with either a HTTP or IPC connection.
RESTful API is an interface that two computer systems use to exchange information securely over the internet. Most business applications have to communicate with other internal and third-party applications to perform various tasks.
RPCs allow communications with servers remotely and provide the ability to execute programs in a separate location. In blockchain terms, an RPC allows access to a server node on the specified network and allows you to communicate and interact with that blockchain.
Is crypto API safe?
CyberNews researchers found that cybercriminals are able to abuse cryptocurrency exchange API keys and steal cryptocurrencies from their victims' accounts without being granted withdrawal rights.
PHP is often used to develop blockchain solutions of different complexity ranges. Something that is a ripple effect of its huge open-source community and object-oriented features.
Blockchain is platform and language agnostic. That means, you can use any popular programming language to create a blockchain. Some of the popular blockchains are developed using C++, Java, JavaScript, Go, Python, C#, Ruby, Solidity, and PHP.
However, things change when transactions between two or more parties have to be highly customized and are constantly changing. In that case, creating a smart contract for every possible transaction becomes too much of a hassle. As a result, a blockchain solution would not be advisable.
The first problem is that without adequate knowledge on how exactly to implement the technology, many companies simply steer clear of it. Blockchain is new territory for everyone, and the reluctance of many to put trust in the system contributes greatly to a delay in widespread use. Most are wary of the unknown.
- Step 1:Data. The type of data stored in a block differs based on the blockchain. ...
- Step 2: hash. A hash, similar to a fingerprint, is also included in the block. ...
- Step 3: Previous data hash. A hash of a previous block is the final piece in a blockchain.
Your private key is what links you uniquely to your blockchain address, while your seed phrase is a fingerprint of all your blockchain assets that you can use as a back-up if you lose your crypto wallet.
In order to access the extended public key of an account, click on the “Account info” button in the upper right corner. You will then see all the extended public keys that are associated with that account in the form of a QR code and the plaintext key below.
A public key is a cryptographic code that allows users to receive cryptocurrencies into their accounts. The public key and the private key are the tools required to ensure the security of the crypto economy.
An extended public key, or xpub, is a public key which can be used to derive child public keys as part of a Hierarchical Deterministic (HD) wallet. An extended public key is a Bitcoin standard established by BIP 32 and is mainly used by a wallet behind the scenes in order to derive public keys.
What is YPUB address?
A ypub is a form of extended public key (xpub) which follows an additional standard defined in BIP 49. Xpubs, ypubs, and zpubs all allow a wallet to generate a deterministic tree of public keys, but each form of extended public key instructs a wallet to derive different address types.
Proof-of-Stake is the so-called better way of solving cryptographic problems. Following are a few cryptocurrencies that use the PoS model that is faster and more secure than PoW.
