A lot of work has been done on refactoring Bytecoin Core’s source code. This process started with the version 0.8.11, which had Bytecoin high-level API interface declared for the first time. The newly released Bytecoin Reference Client v.1.0.3 is the next significant updated for the Bytecoin Core.

Here I will explain what has been happening under the Bytecoin's hood and what our technology vision is. This description is crucial to understand Bytecoin’s roadmap and the necessity to pursue its vector.

The v.1.0.3 release notes focus on the following updates:

• In-process INode implementation for applications
• Low-level ITransaction API interface for ordinary and multisig transactions
• Simplewallet migration to high-level API (namely, INode plus IWallet)
• Instant transaction notifications for in-process INode

Purpose of this update

V.1.0.3 is an important milestone on the way to standardize various components' access to Bytecoin network. It is also a requirement for Bytecoin GUI Wallet, which is coming out later this week.

We are currently getting Bytecoin Wallet ready for the release, and have already rolled out the new version of simplewallet. These wallets are very different, as simplewallet doesn't provide real-time interaction and shows only a tiny part of the information that Bytecoin Wallet has. However, both wallets are powered by exactly the same two high-level API interfaces: INode and IWallet. This allows us to greatly unify Bytecoin source code and improve development process efficiency.

What is even more important, the newly updated high-level API gives 3rd party developers the native access to all Bytecoin features. As of now, any developer wishing to create his own native Bytecoin wallet has all the tools available.

We firmly believe that for the vast majority of cases 3rd party developers should operate on the business logics level, not going into technological hardcore. Our high-level API (namely, INode and IWallet interfaces) serves that very purpose. It is much easier to operate with from inside a C++ application than the classical bytecoind and simplewallet REST API. It gives access to all main Bytecoin features in a convenient and comprehensible way. For example, you don't need to take care of an instance of simplewallet running in the background to power your GUI wallet. Business can focus on the user experience and let IWallet work out-of-box! And in case you need to have a higher level of control over CryptoNote protocol, utilize low-level ITransaction interface instead of high-level IWallet.

By introducing such a level of abstraction, we greatly simplify the experience of applications developers that work with Bytecoin. Our high-level API is a single point of responsibility. In case you need a method that is not yet provided, you may contact Bytecoin Support and have it implemented in the upcoming releases.
