Innovative, ultrafast, free blockchain platform

In short, GraphQL is a protocol that defines an algorithm for searching information in a database. It was born in the depths of good old Facebook as a response to the request of users and developers. The challenge faced by the creators was to optimize the algorithm for processing search queries on the platform.

Before touching on the use of GraphQL in one of new blockchain platform – Free TON, let’s talk about the protocol using a simple example. Let’s say you want to find out who constantly likes posts about particular political party activities or to summarize people who put a laughing emoji under serious texts about harassment and violence. Recall that based on search queries on Facebook arrays of information about the preferences and attitudes of users, the use of which provides interest groups with tools of influence. 

Initially, the existing query algorithm allowed storing the received data as duplicate information, distributed by its characteristics on different servers. The optimization of this algorithm was the development of a syntax that describes to the user how data should be queried, then processes the databases, and finally provides the user with information sorted according to the query. This intermediary client is called GraphQL.

GraphQL, adapted by TON Labs developers, is also used in the Free TON blockchain. There, it is an additional protocol layer, which can perform several complex operations: to collect information from various databases, process it and return to the client in a single request. 

Technically, it looks like this. Each full node contains all information about all blockchain transactions. GraphQL acts as a protocol to it, which is additionally installed by the owner of the node. The graphical interface of this protocol makes it possible to make a search query across the entire blockchain. For example, who and from which address made the transfer, data on the size of the stake, the share of personal contribution from the total investment in the DePool. GraphQL is installed on a full node of the owner’s choice.

The convenience for the user is that with GraphQL he can extract a large set of complex data with just one request to the service. Also, using the input fields, it can immediately determine in what form it wants to receive information.

This gives the protocol flexibility: for example, you can select all the transactions for a single account, or you can trace the dynamics of the processes in the complex by adding new fields. There is also a subscription feature, which allows you to receive information about changes in any parameter, for example, information about transactions from a certain address — a kind of notification.

There are also advantages for developers: GraphQL is a certain level of abstraction for the user, behind which the developer can hide a complex architecture, editable database.

SDK Product Owner at TON Labs, Ekaterina Pantaz, Answers Questions

Ekaterina noted that initially, users were inclined to use the more familiar REST API, but in the end, everyone quickly got involved and there were no problems specifically with GraphQL.

How was the work on the API based on the GraphQL protocol?

The TON Labs development team added basic blockchain access when developing the API (application programming interface), which allows to get information on blocks, transactions, messages and accounts, as well as to send external messages to the blockchain.

API functions have been expanded to find SUM, COUNT, MIN and MAX by data, and the Counterparties function has been added, which returns a list of addresses with which the account has ever interacted, sorted by the time of the last interaction. 

What changes are planned in working with the GraphQL protocol?

TON Labs is currently working on exchanges module that will allow to easily add TON to any exchange. 

The API already allows you to get all the proofs to prove the data it returns, and soon functionality will be added to the SDK, with which it will be easy to do this.

Do you have data on how many nodes and full nodes this protocol is installed on?

There are no such data now. We have three full nodes and I know other validators have a couple of nodes, but I do not have a complete list.

 Is there any monetization algorithm planned?

Yes, there will be a contest of design economical system for Web Free Node soon with good prize money – 115 000 TON Crystal ( about 45 000 USD).

Nigeria to Launch a Pilot for Its CBDC in October

Published

on

Amazon seems determined to maintain its reputation as an innovative company and is looking to experiment with cryptocurrencies through a digital currency payment and blockchain unit.

According to an announcement posted on Thursday, Amazon is looking for a blockchain specialist to lead its Digital Currency and Blockchain strategy.

The Payments Acceptance & Experience team is seeking an experienced product leader to develop Amazon’s Digital Currency and Blockchain strategy and product roadmap … You will work closely with teams across Amazon, including AWS, to develop the roadmap, including the customer experience, technical strategy and capabilities as well as the launch strategy.

What Amazon is Looking For

The expert must have at least an MBA or equivalent degree, 10+ years of business or technology experience, team management skills, understanding of data and metrics, and good communication skills.

The corporation did not disclose any salary offer. The person must be based on or willing to move to Seattle, Washington.

Amazon seems to be convinced of the need to innovate in the field of payments and finance. The cryptocurrency and blockchain development team is a sign of the company’s interest in exploring these emerging technologies to offer better financial products.

According to an email shared by Business Insider, Amazon’s team confirmed its interest in exploring an approach to the world of cryptocurrencies. Still, they did not specify whether it would be through the development of a proprietary currency or through the acceptance of cryptocurrencies as a means of payment:

“We’re inspired by the innovation happening in the cryptocurrency space and are exploring what this could look like on Amazon … We believe the future will be built on new technologies that enable modern, fast, and inexpensive payments, and hope to bring that future to Amazon customers as soon as possible.”

An Old Relationship With Crypto

Amazon’s interest in the world of cryptocurrencies isn’t new. Back in 2017, it purchased, at least preemptively, a number of domains linking its brand to cryptocurrencies, including amazoncryptocurrency.com, amazoncryptocurrencies.com, and even amazonethereum.com.

However, at the time, Patrick Gauthier told CNBC that the e-commerce giant did not have much interest in cryptocurrencies and had no plans to support crypto payments.

In fact, the Pay With Moon plugin that allowed payments on Amazon with Bitcoin through Lightning Network had to change its business model to instead allow its users to purchase virtual credit cards instead of paying directly on Amazon’s site.

Also, as Cryptopotato reported in February this year, Amazon launched a job offer for a new payments system involving “Digital and Emerging Payments (DEP),” although they did not mention a direct relationship with Bitcoin or any cryptocurrency either.

This time, however, Amazon seems more willing to go public with its casual relationship with cryptos.

Locked Out of Millions: Couple Can’t Access $5.8M Worth of Ethereum

Published

on

Yuki and Art Williams, who purchased 3,000 Ethereum coins back in 2014, can not open their crypto wallet. The family claims that the essential JSON file was never downloaded, and thus they don’t have access to their $5.8 million.

In Search for Help

According to the American media 7news, the Washington DC family Yuki and Art Williams possess 3,000 ETH coins in their crypto wallet. Unfortunately, the wife and husband can only see them and not access the assets. The couple insisted that when they bought the assets in 2014, the JSON file was never downloaded. Art Williams said:

“The instructions were to leave your computer on for an hour and a half and as the progression bar showed it populating the JSON file would appear. Unfortunately for us, it did not appear.”

Calculated in today’s prices, the wallet contains $5.8 million. Mr. Williams told 7news that the Ethereum Foundation promised him to solve the issue and send him a backup JSON file. However, the family is still waiting.

In another attempt to access their funds, the couple e-mailed the Foundation based in Switzerland and showed them proof of purchase and screenshots of the problem. 7news also tried to reach out to the Ethereum Foundation but received no comment.

The last move that the family is yet to make is to hire a law firm that would open a case in court in Switzerland. The attorneys would demand that the Ethereum Foundation grant a JSON file to the desperate couple during the process.

“Devastating, to say the least. Obviously, that’s life-changing money,” added Mr. Williams.

The Man Who Lost Access to 7,002 BTC

Investing in cryptocurrencies is not risky only because of the volatile nature of the assets. Apart from that, investors need to save and protect their private keys. In case someone loses their private keys, that could lead to an irreversible disaster. Such is the case with Stefan Thomas and his bitcoins worth more than $223 million.

As CryptoPotato reported earlier in the year, the resident of San Francisco produced an educational video called “What is Bitcoin?” for another crypto fan and received 7,002 bitcoins for his services.

However, Thomas didn’t pay much attention to his new holdings as they had a little-to-no value at the time, and he lost the digital keys to the wallet. In the following years, though, BTC’s price exploded, and now the 7,002 coins are worth around $223 million.

The wallet called IronKey allows users ten attempts to guess the password. So far, Thomas has tried eight times to access the funds, but they were all unsuccessful. If he fails ten times, the wallet will be encrypted forever.

“I would just lay in bed and think about it. Then, I would go to the computer with some new strategy, and it wouldn’t work, and I would be desperate again,” the man revealed.

To avoid any of the above, it’s highly recommended that you take crypto security seriously and make sure to always follow these tips.
