BlockCypher is an IT company established in 2014 and specialising in blockchain web services and middleware. Its founders are Catheryne Nicholson and Matthieu Riou, and the company’s headquarters are in Silicon Valley, California. 

As an infrastructure provider, the company is highly versatile and can operate as peer-to-peer, business-to-consumer, and business-to-business payments – making it perfect for online shopping, quick and secure transacting, or even playing at the best crypto casino.

The web services provider is also great for identity management, know-your-customer solutions, and effortless cross-border payments. The platform has excellent scalability and stability due to its cloud-optimisation infrastructure and multiple data centres. 

In case you didn’t know, BlockCypher’s explorer supports the most popular blockchains, including Bitcoin, Ethereum, and Dash. Its most popular product is JSON API.

It also provides a publicly accessible suite of RESTful APIs for popular blockchains like Ethereum and Bitcoin. These include APIs like basic queries such as an address, block, and transaction details to fully-fledged transactions, contract creation tools, and robust WebHook events.

Dynamics Of BlockCypher

BlockCypher’s architecture enables it to operate multiple data centres, contributing to its redundancy and low latency. It offers effortless web APIs allowing developers to create blockchain applications swiftly and confidently. 

The platform’s cloud-optimised architecture is classified as enterprise-grade, which is pivotal for the platform’s reliability, performance, and scalability.

If that wasn’t enough, BlockCypher effectively maintains a distributed database cluster comprising all transactional data for the entire blockchain. The platform also hosts complete node blockchains that are particularly helpful for optimising security regarding the validation and relaying of transactions. 

The driving force of the service is to enable all users to become successful as they create the next generation of blockchain applications.

It has an explorer function, which is open source, and this helps developers use their version of the site without any compromise to the platform. This functionality supports various cryptocurrencies such as Bitcoin, Ethereum, Grin, Litecoin, Dogecoin, and Dash blockchains.

On the company’s blockchain page, developers can view recent blocks, the latest transactions, and block height, amongst other information. 

Users can also view current fee estimates divided into three categories, i.e., High Priority, Medium Priority, and Low Priority blocks.

If that wasn’t enough, the platform also offers transaction confirmation predictions that enable users to view the likelihood that the blockchain will confirm a transaction. This is represented as a percentage predicted of a double-spend transaction attempt being a success. 

It also indicates the miner’s preference for the transaction while claiming to receive transactions quicker than other comparable blockchain explorers

24/7 Support

BlockCypher is fully focused on the success of its users in its quest to create next-generation blockchain applications.

Explorer Security

Using BlockCypher’s APIs does not prevent users from validating its APIs with reference implementations. In fact, the great thing about engaging with a distributed system like this one is that users can confirm claims on the platform, such as quickly verifying other block explorers or their copy of the blockchain.

All account passwords are salted/bcrypt-hashed, which means that the damage would be very limited even if a hacker had gained access to your account. 

The most damaging aspect would be that the hacker could steal token access. But this can be seamlessly fixed through a password reset or by generating a new token. 

BlockCypher does not store any user’s private keys, which gives users confidence that nothing much can be stolen if their account is infiltrated.

The platform uses private keys temporarily in the Contract API, Microtransaction API, and the Payment Forwarding API and does not store them. 

Moreover, it discards these temporary private keys the second there is no longer any use for them. 

BlockCypher also requires users to sign their transactions locally, especially for large-value transactions or operations. While this process can be a little more complicated, it is much more secure and helps users to keep their blockchain assets under control.

Platform Restrictions

While there are many incredible ways to use BlockCypher’s platforms, users are subject to restrictions on their use. Users or third parties of users will not be permitted to reverse engineer, decompile, disassemble, or make any attempts to discover its source code, object code, or the underlying structure, ideas, or algorithms.

BlockCypher users may not modify, translate, or create derivative works based on the platform. Moreover, they may neither copy, rent, lease, distribute, pledge, assign, transfer, or encumber rights to it. 

Users are also prohibited from using the service for timesharing or service bureau purposes or for the benefit of a third party. In addition, users cannot remove or alter labels or proprietary notices from BlockCypher. They can only use the service in compliance with its terms and conditions and the applicable regulations and laws.

Despite these restrictions, which are extremely fair to users, BlockCypher is undoubtedly a platform that encourages its customers to exercise their creativity to aid in its development.


User Fees

For those who are starting with the platform, it is free, to begin with. If you realise that you need a bigger plan, however, you will need to get in touch with BlockCypher to arrange a suitable one for your needs. There are a few things to consider when it comes to the fees.

Customers who use BlockCypher and exceed the usage capacity based on their plan tier will not be able to access the platform until they settle their account. It’s that, or wait until the new month kicks in. 

Customers must pay their fees in advance, and the platform only accepts US dollars.

Then those who take longer than 30 days to settle their accounts incur finance charges of around 1.5% per month together with the expenses for collection – if applicable. 

Additionally, customers are liable for all taxes associated with their account, and BlockCypher fees are non-refundable.
