Background

Award Pool is a platform that provides companies with a unique way to engage their audience with custom-made challenges and competitions. They had already built a full-fledged user interface, but they were struggling to implement a crucial component that has been making waves in the digital world — NFTs. They had been searching for a tool that would allow them to create wallets, public addresses, private keys, and mint/burn tokens on the fly. However, they were unable to find a simple API that abstracted…

Background

CO2IN is an ambitious project that aims to turn European businesses, communities, and citizens into active participants in the fight against global warming. How? By buying up carbon allowances that would otherwise be used by Europe’s worst polluters.

With CO2IN, users can purchase carbon offsets that are backed by real and limited underlying assets. With many carbon offset programs, companies sell offsets with the promise that they will do something environmentally beneficial — like planting trees or otherwise contributing to sustainability initiatives. However, when users buy a carbon offset with CO2IN, they remove…


February was another busy month at Tatum and an exciting one for the world of blockchain in general! We kicked off our Community Talks series with some insightful interviews with leading figures in blockchain and added support for Quorum, TRON, and Scrypta. Tatum is now officially part of the Blockchain Game Alliance, and we’ve put up some new tutorials to get you well on your way to blockchain mastery.

Introducing Community Talks


Have you ever wondered if there was an easier way to complete transactions without dealing with online wallets, banks, or third-party applications? There is, and it’s called blockchain.

What is blockchain?

Most of us are familiar with the concept of cryptocurrency or at least have heard of Bitcoin. The technology on which they run is known as a blockchain. Blockchain technology has made cryptocurrency much safer, decentralized, and protected by robust encryption algorithms.

The fact that blockchain was designed to be decentralized and distributed on a network of numerous computers was to make it immune to any form of data tampering, manipulation, or…


16 February 2021, Brno — a major Czech success in the Mecca of startups was announced by the Brno tech outfit Tatum, which specializes in simplifying blockchain app development. The company was recently accepted into the coveted SkyDeck accelerator in Silicon Valley, and received investment from its fund, which includes highly reputable shareholders such as Sequoia Capital and Mayfield Fund.

Thousands of startups from across the globe apply to SkyDeck each year, but only the top 16 are selected by the accelerator.

“Tatum is the first ever Czech startup to join this very selective accelerator. …


We interviewed Burak Öner a blockchain developer about his experience with Tatum. Here’s what he had to say.

Hi Burak, can you please tell us a little bit more about yourself?

I’m from Turkey. MD, entrepreneur, and full-stack developer. I’ve developed many software and blockchain projects.

What is the key development factor that brings blockchain projects to life?

On the blockchain side, you need a wallet manager system in your projects. But you need to integrate it into each blockchain separately — Bitcoin, Ethereum, Ripple, and many others. Every chain has a different structure and you need to write different…


If you want to use crypto, you need a wallet. That’s clear for everyone. But what about developing a robust crypto wallet? That’s when clarity turns into ambiguity.

Let’s introduce a simple yet powerful guide which clears out all the ambiguity around blockchain development. (Code included — we have got you covered developers)

NOTE: The guide will focus specifically on custodial wallet’s backend. However, I will also post a link for a non-custodial wallet guide at the end in case you are interested in that one.

The Old-school Way to Develop Blockchain Apps

Back in the old days, you would have to create a development plan, raise…


DeFi: short for ‘decentralised finance’. It’s basically using cryptocurrency and/or blockchain for (existing) financial applications.

What is DeFi?

In the big picture, DeFi removes the middleman from financial transactions.

To understand why that matters, we have to return to the idea of blockchain technology. The essence of blockchain is that entities can hold a copy of a history of transactions. This means a central, single source isn’t in control as gatekeepers. Hence, it reduces the speed and sophistication of transactions while keeping users in control of their money.

By using blockchain to support smart contracts, you can write programs that interact with money…


In the crypto world, an initial coin offering (ICO) is what’s considered the IPO of crypto ‘stock’, although with some differences. Firstly, you aren’t going to own a share in the future company, and secondly, the ICO has to be connected to a blockchain.

Instead, crypto-tokens are offered in a ‘crowdsale’, which allows anyone to buy and fund a company in its pursuit of some groundbreaking technology that’s said to rock the crypto world. Often, only a limited number of tokens are offered, which can be sold in exchange for Bitcoins or flat money. …


OK, have the date of our demo launch. Finally. We know it took longer than we expected, but on the other hand, we developed better stuff. See some pictures demonstrating the results of deja vu on the live graph as a shadow view. We think that this is a breakthrough👍

📅 12. 8. 2020 is our demo launch date.
