Smart Contract Chainlink Startup Tapped By Google As Blockchain Partner

Published

on

Google has tapped a startup token project, Chainlink, as an official Cloud Partner and the relationship suggests a deep and detailed interest in blockchain technology by the Mountain View giant.

The partnership, described in a detail Google Cloud blog post, aims to place BigQuery data on the blockchain using a “Chainlink oracle smart contract.” BigQuery is Google’s data warehousing and business intelligence solution.

Founders Sergey Nazarov and Steve Ellis created SmartContract.com and Chainlink in order to create proper middleware between traditional data sources and blockchain-based systems. They are working with money movers SWIFT as well as database company Oracle.

“We realized that a reliable oracle mechanism is a gating issue for the creation of most of the use cases that people are expecting from our space, and set out to solve this limitation of blockchain infrastructure with security, reliability, and easy consumption of the inputs/outputs needed by smart contracts to reach this new level of usefulness,” said Nazarov. “In this case we are working with Google as someone who we’ve successfully made an on-chain data provider that can now securely interact with smart contracts that want to consume their high quality data and/or various off-chain services. We’re trying to create the next generation of smart contracts that are able to go beyond tokenization, and will find their usefulness based on interactions with market events (DeFi), IoT events (Decentralized Insurance) and various other use cases.”

It’s important to note that this is one of the few blockchain products that Google has singled out in this way making the announcement a feather in Chainlink’s proverbial cap.

“At a high level, Ethereum Dapps (i.e. smart contract applications) request data from Chainlink, which in turn retrieves data from a web service built with Google App Engine and BigQuery,” wrote Allen Day, a Developer Advocate with Google. “One or more Chainlink nodes are listening for these calls, and upon observing, one executes the requested job. External adapters are service-oriented modules that extend the capability of the Chainlink node to authenticated APIs, payment gateways, and external blockchains. In this case, the Chainlink node interacts with a purpose-built App Engine web service.”

All of this means, quite simply, that Google’s products can now interact with decentralized applications in the same way, say, a client app can interact with a standard database server. Chainlink acts as the data middleman.

“Allowing smart contracts to interact with a data source of Google BigQuery’s quality, enables various new and exciting capabilities for Ethereum contracts in general e.g. more private ethereum transactions via submarine sends, as well as various exciting use cases/Dapps like prediction markets that will base their outcomes on BigQuery’s data,” said Nazarov. “We’ve really enjoyed working with the folks at Google on this initial implementation, and we’re looking forward to working with them in many more ways to come.”

Chainlink’s associated token, LINK, shot up on the news, hitting an all-time high of $1.95 before dropping to about $1.72 today.

A New Bitcoin Exchange Point On the Colombian-Venezuelan Border Will Help Refugees

Published

By

A new cryptocurrency exchange service is available on the border between Colombia and Venezuela and its aim is to help refugees traveling across the Simon Bolivar International Bridge.

Visitors are now able to use the point-of-sale service with cryptocurrencies to buy goods. The POS is located in Santander, Colombia, just across the border from Venezuela. Panda Group created the payment alternative with refugees in mind. The group, a Columbian-Venezuela joint venture, announced the implementation of the new service through their Twitter account.

According to the data published by Coinatmradar.com, the service lets users exchange using bitcoin (BTC), bitcoin cash (BCH) and dai (DAI), and converts them into to Colombian Pesos (COP).

At the physical location – a small phone service provider in a mall called La Parada – customers can buy bitcoin with prices based on the Localbitcoins rate in pesos. The service will charge 10 percent above the market price and those who sell their bitcoins will do so for 5 percent more than the established market value.

This is not the first cryptocurrency service in the country. The Panda Group has already installed another five cryptocurrency exchanges in Colombia, most of them in the Colombian capital, Bogotá.

According to Panda CEO, Arley Lozano Jaramillo, their solutions are focused on helping the Venezuelan users and they announced the addition of a new service called Xpay.Cash to encourage adoption.

“This service is for all our brothers to pay directly in Cucuta with their cryptoassets and mitigate the loss of exchanging from BTC to COP, which represents a loss of at least 20%,” Jaramillo said.

Colombia has the highest rate of cryptocurrency investors in South America, next to Brazil. There are reportedly over 20 businesses accepting bitcoin payments in the country. The establishments are mainly focused in tourism, food and digital services.

Bitcoin At The Border

The ATM installed in Villa del Rosario City is connected to the Venezuelan border by the state of Tachira. The states are only separated by the Simon Bolivar International Bridge, one of the most heavily traveled borders used by Venezuelan refugees.

The refugee situation has also sparked a focus on the cryptocurrency, mainly for humanitarian aid purposes.

On the other hand, the last point of sale with cryptocurrency was implemented in Cúcuta, another border location with an growing Venezuelan population. The state also has a Bitcoin ATM, one of forty-two in the country.
