We are used to the traditional involvement of a middleman or a broker when it comes to money or things bought with money. Well it doesn’t exactly stop there. Money is not the only asset that sees the controlling authority apart from the owner, data joined the party majorly since user generated content became the defining component of web 2.0 controlled by leading parties like Facebook. In such a system where the central authority is technically the owners of the data therefore have the controlling power over prices as well, Users have to be dependable on such parties for ethical practices and interest. 

Why Blockchain Programming?

If you have been in touch with the updates and events of the fin-tech world for the past decade involving cryptocurrency, then there is a good chance you are familiar with the blockchain technology that runs the bitcoin network. Blockchain programming was designed while keeping in mind the objective of minimizing trust within any central or controlling authority by decentralizing the data establishing a network of individual peer to peer transactions that can be directly connected without the involvement of a middleman or central authority like a bank.

One of the most well known uses of blockchain programming can be well observed in cryptocurrency, a digital currency with no governing authority. Bitcoin is the first of its kind with this technology surviving in an interdependent and sustained ecosystem involving the participation of miners and their hash contribution thus controlling the supply of the currency but that is a different topic for another time. Blockchain has led different sectors of the world like agriculture, health, energy and others to find solutions and then implement them on the problems that were previously impossible to solve including application of this technology to smart digital contracts, rendering the need of a middleman null to verify them in the first place.

For every aspiring enthusiast who wants to learn blockchain coding, it is quite natural to have questions. Even with a programming background it is still important to learn types of blockchain programming, what language to use for programming blockchain based apps efficiently or what are the best platforms for blockchain coding.

Blockchain Programming Types

  • Building Decentralized app (DApp)

What makes dapp different from normal applications is that its back-end code runs on a peer to peer network which is decentralized whereas applications in general have its back-end code running on centralized servers. But similar to all apps, the front-end code has no control over the back-end irrespective of the language or user interface used.

  • Blockchain Architecture

It is highly important for features like protocols and architecture of the blockchain needs to be settled before the great launch that is written in code. Going back to 2009, before the launch of the bitcoin blockchain, the protocols and rules over the situation were coded in c++. Languages like C and java are generally used to write this kind of coding that works with the system.

Blockchain programming platforms

Ethereum 

An open source blockchain platform, ethereum provides various programming languages like python, java, C++ and more. Mainly meant for developing decentralized apps to run on blockchain technology, ethereum’s blockchain platform also offers smart contracts to go through the network.

Hyperledger 

With a goal to provide advanced blockchain technology with easy to use API, hyperledger is a project of open source blockchains facilitating training and tools to support associative development of blockchain oriented decentralized ledgers inevitably contributing in the advancement of technology.

Hyperledger facilitates all components of blockchain architecture including information sharing and data privacy that ensures security and oversees the fact that the participating parties are the only one with access to it.

Best Blockchain Programming Languages

With so many advanced choices in programming languages, why C++ is still the modest choice for blockchain programming is due to some very appealing features. Due to the difficulties faced in developing blockchain, it needs efficient management of resources, while supporting its interaction with undependable nodes but still facilitating fast service to all them which is a crucial factor to a cryptocurrency. C++ offers total control over memory usage and CPU to adhere to these demands delivering higher performance.

  •  JavaScript

JavaScript is generally used in creating efficient and interactive web pages and is known as one of the most famously used languages in developing software with HTML and CSS, it definitely gives an extra touch to its features and services.

JavaScript capabilities of handling communications among different blockchain nodes makes it suitable for designing blockchain operations, given the increasing number of blockchain users. However it is still questionable in front of C++ with its capability of expanding a system’s processing power.

Python is comparatively a modern language with simple syntax quite similar to English language, making it highly suitable for new coders and is known to create web based applications on a server with capability to handle larger amounts of data and complex mathematics.

Whatever the case, it is not possible to leave out python from the list, as almost every blockchain ecosystem has a public tool that is coded on python.

Multinational payments firm Sia is partnering with cryptocurrency custodian Hex Trust to help its European banking clients hold digital assets.

“When you have one bitcoin, it’s not a big problem, but when you start adding 10, 20 or 100, you have a treasury and you have to decide where to store this,” said Daniele Savarè, SIA’s innovation and business solutions director. “We are discussing digital custody needs with banks in Europe.” 

The firm is also helping banks manage and safekeep security tokens and central bank digital currencies, he added.

Through SIA, Hex Trust plans to offer European banks the software to custody digital assets on behalf of their customers. Hex Trust will also act as a sub-custodian for banks that don’t want to directly offer the service, said Hex Trust CEO Alessio Quaglini. 

Currently, Hex Trust works with three banks – Mason Privatbank Liechtenstein AG and two unnamed Asian banks. Quaglini said Hex Trust has 10 other banks that are exploring the custodian’s products.

Going forward, SIA will be the primary distribution partner for Hex Trust to offer digital-asset services to banks in Europe, Quaglini said.

Collider Labs has raised $1 million to be invested in early-stage blockchain and cryptocurrency startups.

In an announcement Thursday, the venture builder said the raise had brought on board several notable limited partners including Efficient Frontier CTO Alon Elmaliah and Follow [the] Seed Founding Partner Andrey Shirben.

Collider provides funding and liquidity and actively participates in building up startups alongside their communities and founders, according to the firm’s founding partner, Avishay Ovadia.

The company is actively seeking to invest in early-stage blockchain and crypto startups globally, with a focus transparency, privacy and “fairness.”

Collider “is a venture builder that somewhat resembles an accelerator” Ovadia said. With some “key characteristics” that differentiate it from a typical accelerator.

Venture builders, also known as startup studios, pair with early-stage startups and utilize their own ideas and resources to, if all goes according to plan, construct viable enterprises.

According to Ovadia, Collider forms partnerships with founders, invests in teams and works alongside them as what he calls “Investors in Residence.”

Voyager Agrees to Buy LGO Markets and Merge 2 Firms’ Tokens

Two cryptocurrency trading firms are merging, and in a rare twist, so are their tokens.

Two cryptocurrency trading firms are merging, and in a rare twist, so are their tokens.

Voyager Digital, a publicly traded digital asset brokerage with offices in New York, has agreed to buy LGO, a French crypto exchange primarily serving institutional investors, as the company expands to Europe.

The transaction requires regulatory approval, which the parties said they expect to receive by the end of this year, along with the token swap. The value of the deal will depend on the value of Voyager’s shares, and the firms’ tokens, at closing; at current prices, it would be in the low seven figures.

As such, this deal is dwarfed by this year’s blockbuster crypto M&A deals such as Binance’s acquisition of CoinMarketCap, estimated to be worth $400 million, and FTX’s $150 million deal to acquire Blockfolio.

What makes this deal unusual is that the two companies’ utility tokens, VGX and LGO, will be swapped into newly minted tokens featuring decentralized finance (DeFi) functions such as community governance and staking at an initial interest rate of 7%.

“We think this is really taking the old-school mergers and acquisitions to the token world, which hasn’t been done before,” Steve Enrlich, Voyager’s co-founder and chief executive officer, told CoinDesk.

Upon completion, Voyager, which is publicly listed on the Canadian Securities Exchange, will issue one million shares for the acquisition and operate in the European retail market with LGO’s Virtual Asset Service Provider registration with the French Financial Markets regulator (AMF). All activities will be conducted under the Voyager brand and LGO will discontinue its institutional services on Oct. 31. Shares of Voyager closed at C$0.67 ($0.51) on Wednesday.

Hugo Renaudin, co-founder and chief executive officer of LGO, told CoinDesk that the French company made the deal after it decided to shift its focus from institutional clients to increasing value for its token holders.

“The key decision-maker is what will bring the most value to our tokens,” Renaudin said. “So we have this token. We have token holders and they’re mostly retail [clients].”

LGO launched an initial coin offering (ICO) in February 2018, according to its website, which raised 3,600 bitcoin (worth about $36 million at the time). The company’s white paper shows that 60% of the tokens were distributed through a pre-sale process, while 20% of the supply went to LGO’s founders and advisors.

At its peak in April 2018, the LGO token’s market cap was nearly $40 million, according to data from CoinMarketCap. On Wednesday, that value was calculated to be $1.5 million. 

Renaudin told CoinDesk that the company’s other option would have been focusing on better serving its institutional clients, which means its spot exchange would have to provide new and exotic derivatives products. After consideration, he said that the team had decided to change its focus to retail customers instead.

The merger comes during a time of regulatory crackdown on crypto derivatives trading around the globe. Popular crypto derivatives exchange BitMEX was charged by the U.S. Commodity Futures Trading Commission (CFTC) with facilitating unregistered trading activities, while in the UK, the Financial Conduct Authority (FCA) has banned crypto derivatives for retail consumers.

This is not the first acquisition by Voyager, which went public in early 2019 in a reverse merger with the shell of a Canadian mineral exploration company. Previously, it acquired wallet startup Ethos.io for about $4 million.

Voyage’s revenue in the most-recent fiscal quarter, which ended Sept. 30, surged to about $2 million, compared with $1.1 million during the fiscal year ending in June.

“We are becoming the financial service firm of the future, which means I will look at acquisitions that can add products, customer assets to the platform, or tokens and other communities that can be accretive to what we are trying to do,” Enrlich said. “And adding these pieces together we are going to either do it organically or through more acquisitions.”
