Blockstream developer Russell O'Connor published white paper of Simplicity, a new programming language designed to be an alternative to existing languages used to create smart contracts. It is assumed that Simplicity can be implemented over time in the bitcoin protocol via the softfork mechanism.

As stated in the blog Blockstream, Simplicity is based on the algorithm of sequential computation and offers several important improvements, the main one of which is the extension of the language capabilities.

 One of the problems with Bitcoin Script, Bitcoin’s own programming language, is that a number of opcodes were disabled in Bitcoin’s earliest days. For example, you can add numbers in Bitcoin Script, but you can’t multiply them.

Among other important features, which Blockstream pays attention to, is an increased level of security - Simplicity is a Turing incomplete language that provides limitation of a recursive call, protection against endless cycles and allows for static code analysis.

Also Simplicity has built-in support for Merklized Abstract Syntax Trees (MAST).

All this in combination allows you to create a more secure, efficient and functional code for smart contracts.

A more detailed analysis of Simplicity is expected in the near future, while you can get acquainted with whitepaper

Switcheo to Launch Cross-Chain ETH-NEO Atomic Swaps

Developers says that the technology of atomic swaps has been known for few years, but is not popular, since its implementation in practice is quite complicated

Switcheo announced the official launch of the atomic swaps feature for the Ethereum and NEO blockchains.

From now on, Switcheo users have access to the inter-block exchange of their own token exchange, SWTH and ETH, which allows for the transfer of assets between two markets represented on the trading platform and makes Switcheo the first decentralized exchange that implements this functionality.

A challenge with existing trustless exchanges is that trades are confined to individual blockchains, limiting the market combinations that can be offered to users” says . With the launch of the new feature, users can now trade conveniently between ETH and NEO markets, while retaining full custody of their funds.

According to the developers, the technology of atomic swaps has been known for several years, but is not widely used, since its implementation in practice is quite problematic. Switcheo lead developer John Wong explained that his team spent a lot of time adapting the process to the user's needs and achieved the desired result.
