Smart contracts could soon get a boost in bitcoin as prominent programmer Pieter Wuille has unveiled a new coding language designed specifically for their use.
Posted to the bitcoin developer mailing list Monday, the ‘Miniscript’ language aims to make it easier for programmers to write up “smart contracts” or conditions for spending bitcoins.
In a move that could compromise ethereum’s long-held dominance as the world’s top platform for smart-contract development, blockchain interoperability project Cosmos will offer users the choice to code in at least three different programming languages.
The first language to be supported on Cosmos is called Ethermint, a direct replica of ethereum’s smart contract language Solidity. Aimed at making it easier for ethereum developers to port their applications to the Cosmos network, the Ethermint project has been in the works since as early as 2016, said Zaki Manian of Tendermint, the company that built Cosmos.
BitFlyer Blockchain and Japanese business giant Sumitomo Corporation have joined forces to develop a blockchain service that allows users to sign rental contracts over a mobile app and more.
The project appears to be an attempt to tie up almost the whole rental business in one smartphone app. CNET Japan reported Tuesday that the firms plan to develop a “one-stop shop,” allowing users to search for properties, make bookings, sign contracts and payment different expenses, as well as providing contract renewal and exiting procedures.

Rating agency Moody’s has warned of several risks of private, centralized blockchains in a report for clients examining the pros and cons of the technology for financial firms.
Titled “Blockchain Improves Operational Efficiency for Securitizations, Amid New Risks,” the April 25 report describes the basic features and promises of blockchain technology, explaining how businesses like banks can leverage it to their benefit.
In the document, seen by CoinDesk, Moody’s emphasizes the difference in security between private and public blockchains, saying that consensus mechanisms in private chains may not be as strong as those seen in public chains, or may be absent altogether.

Blockchain technology is shaking up the legal industry.
At least that’s according to prominent blockchain industry attorneys, Angela Angelovska-Wilson and Lewis Cohen, who revealed exclusively to CoinDesk Friday that they have started their own law practice focused on the nascent industry.
Called DLx Law LLP, the firm opened its doors this month, with offices in New York and Washington, D.C. Its founders, Angelovska-Wilson, previously general counsel and chief compliance officer at enterprise blockchain startup Digital Asset, and Cohen, a seasoned securities lawyer, aim to run the firm differently than the typical law practice, in a way that aligns better with the culture of the blockchain space.
It is always difficult for cryptocurrency projects to find their niche market. In the case of Ethereum, NEO, EOS, and TRX, the addition of letting users create and issue their own tokens has done wonders. Similar functionality will come to Bitcoin Cash through the Wormhole project. It is an interesting addition, although no one knows if this will be even remotely successful in the long run.
Changing the Bitcoin Cash Narrative
Over the past few weeks, the discussions pertaining to Bitcoin Cash have not been overly positive by any means.
Bitcoin-built smart contract platform RSK (a.k.a. Rootstock) is merging with an offshoot established by its founders. The partnership will allow it to spread its roots to Ethereum — and beyond.
The company has been acquired by RIF Labs, a development lab that was established by a handful of RSK’s own founders, including CEO Diego Gutierrez-Zaldivar and Chief Scientist Sergio Demian Lerner, who will both assume the same roles at RIF.

Kodak, the iconic photography company first established in in the 1880s, has joined the blockchain and ICO age. Today, January 9, 2018, it announced a new blockchain-based platform with WENN Digital to empower and protect image makers, photographers and artists.
Bitcoin is usually not considered the blockchain best suited for self-executing conditional payments, better known as smart contracts. While it does support basic programmability to enable features like time locks and multi-signature (multisig) schemes, competing projects like Ethereum, Ethereum Classic or Qtum are often expected to better support more advanced applications.

Название: Antshares / NEO
Количество монет: В NEO – 2 монеты. Neo, и NeoGas (подробнее о каждой - ниже). Neo – 100 000 000 монет, минимальная не делимая единица – 1 NEO, если переводить на формат биткоина, то количество NEO - 1 монета. В биткоине – у каждой монеты есть 100 000 000 неделимых частей (сатоши) и всего монет 21 000 000. А в NEO, судя по whitepaper – всего 100 000 000 монет. Однако так же существует NeoGas, которых уже 100 000 000 монет, где каждая монета содержит еще 100 000 000 неделимых частиц, общее количество – 1 000 000 000 000 000 000. Общая сумма монет NEO зафиксирована на уровне 100 миллионов и не может быть увеличена. Наименьшая единица NEO — 1 NEO и не может быть разделена.

Bitcoin’s capacity is limited. Meanwhile, smart contracts can be resource intensive. So even though Bitcoin has always supported basic smart contract functionality, the two have never been a natural match.
But a recent topic of research spearheaded by Blockstream mathematician Andrew Poelstra could help fix this.
As a way to eliminate bugs in high-risk code, a style of software programming known as formal verification is making its way into the blockchain world.
