Translate all reviews to English. Verified Purchase. For what it sets out to do - explain the blockchain file structure - it does reasonably well Most people will use the json-rpc interface. Report abuse. This basically just handholds you through a simple proggy thay can parse a bitcoin blockchain file.
A good, but shallow first exercise. One person found this helpful. Gentle introduction. Report abuse Translate review to English. The very brief 18 page book shows how to read a block chain but misses providing a practical example oh how to futher use what has been learned. It needs to show actual business data, not just the first block in the chain. Back to top. As such, BlockCypher cannot guarantee that it's fully up to date, but we hope it will provide a nice jumping-off point for developers using this language.
We'll endeavor to keep this list updated, if any of these prove obsolete. If there's enough support for a particular language, we'll work with the community to turn it into an officially supported SDK. If your favorite language is not listed above or if you prefers using raw queries, be sure to check our Postman Collection documentation. Currently, there's only one version of the API v1.

Thus, here's an exhaustive list of blockchains and their corresponding resources:. We want everyone to try BlockCypher with as little friction as possible, which is why you don't need a token for any read-only GET calls. Once you have your token, you can append it to all your requests like any other URL parameter if you're using cURL, or through the appropriate method in the language SDK you're using. The hourly rate limits reset on the top of the hour UTC. For example, if you're under the free tier, and you have used regular requests by UTC, you'll hit a rate limit until it resets at UTC.
To request higher limits or SLAs beyond what's offered on the accounts page, please email us. Keep in mind the X-Ratelimit-Remaining attribute corresponds to the hourly rate limit associated with the endpoint you call e. All endpoints that can retrieve a single Object can be batched to return multiple objects. If you're cURLing the API directly, batching simply requires appending each identifier to the previous one using a semicolon check the code pane for an example. The results are aggregated in a JSON array. The other supported client SDKs batch differently, but each idiomatic to their respective language check the code pane examples in each library.
We offer two different options for testing your blockchain application: Bitcoin Testnet3, and BlockCypher's Test Chain. We offer automated faucets for BlockCypher's Test Chain. We recommend using BlockCypher's Test Chain for a variety of reasons:. In case you missed the Resources section , the BlockCypher Test Chain is accessible from this resource:.
To help facilitate automated testing in your applications, a faucet endpoint is available on both BlockCypher's Test Chain and Bitcoin Testnet3. Calling the faucet endpoint, along with passing a valid address, will automatically createand propagatea new transaction funding the address with the amount you provide.
This example shows how to leverage the faucet to programmatically fund addresses, to test your applications. While the example used BlockCypher's Test Chain, the same example could have used Bitcoin Testnet3 and worked the exact same way.
Some of you might be more interested in the endpoints themselves, in which case, feel free to skip to the next section. But for others, a section dedicated to all of BlockCypher's Objects might prove a useful overview, especially if you're new to Blockchain development in general. And in either case, this section provides a comprehensive reference for Objects in the API. For each Object there's a description and a link to a germane API endpoint. Typically returned from the Chain API endpoint. A Block represents the current state of a particular block from a Blockchain.
Typically returned from the Block Hash and Block Height endpoints. A TX represents the current state of a particular transaction from either a Block within a Blockchain , or an unconfirmed transaction that has yet to be included in a Block. Typically returned from the Unconfirmed Transactions and Transaction Hash endpoints.

A TXInput represents an input consumed within a transaction. Typically found within an array in a TX. A TXOutput represents an output created by a transaction. A TXConfidence represents information about the confidence that an unconfirmed transaction will make it into the next block. Typically used as a return object from the Transaction Confidence Endpoint.
A TXRef object represents summarized data about a transaction input or output. Typically found in an array within an Address object, which is usually returned from the standard Address Endpoint. A NullData Object is used exclusively by our Data Endpoint to embed small pieces of data on the blockchain.
If your data is over 40 bytes, it cannot be embedded into the blockchain and will return an error. An Address represents a public address on a blockchain, and contains information about the state of balances and transactions related to this address. An AddressKeychain represents an associated collection of public and private keys alongside their respective public address. Generally returned and used with the Generate Address Endpoint.
A Wallet contains a list of addresses associated by its name and the user's token. It can be used interchangeably with all the Address API endpoints, and in many places that require addresses, like when Creating Transactions.

The name of a wallet must be characters long and cannot start with any characters that start an address for the currency contained in the wallet. For example, bitcoin wallet names cannot start with '1' or '3'. An HDWallet contains addresses derived from a single seed. Like normal wallets, it can be used interchangeably with all the Address API endpoints, and in many places that require addresses, like when Creating Transactions. It also contains the hex-encoded public key when returned from the Derive Address in Wallet endpoint. A AddressForward object represents a request set up through the Address Forwarding service.
How to make a Bitcoin transaction with Python - DEV Community
If you're new to blockchains, you can think of the blockchain itself as an immutable, distributed ledger. Each block in the blockchain is like a "page" in the ledger containing information about transactions between parties. A great place to start understanding the mechanics behind blockchains is the original Bitcoin whitepaper. General information about a blockchain is available by GET-ing the base resource.
For more detailed information about the data returned, check the Blockchain object. The returned object contains information about the block, including its height, the total amount of satoshis transacted within it, the number of transactions in it, transaction hashes listed in the canonical order in which they appear in the block, and more. For more detail on the data returned, check the Block object.
