This week has been yet another exciting one in the digital assets industry. We have had significant research published by both the Philadelphia Fed and Ciphertrace!

  1. OK Group Launches OK Recruit, A Blockchain Talent Development Scheme

“OK Group will train more than 1,000 blockchain elites within 3 years through partnerships with major universities and scientific research institutions in China.”

2. CipherTrace releases Spring 2020 report on cryptocurrency crime and AML

“In the first five months of 2020, crypto thefts, hacks, and frauds totaled $1.36 billion, suggesting 2020 could see the second-highest value in crypto crimes ever recorded.”

3. Fed research: Central Bank Digital Currencies (CBDCs) are competition to commercial banks

“CBDC amounts to giving consumers the possibility of holding a bank accountwith the central bank directly.”


For a long time we’ve observed crypto market data vendors taking existing business models from the ‘traditional’ market data vendors and making a similar tool / API for crypto traders. From raw data normalization and aggregation to tensorcharts to social media semantics data, all are methods of gathering and consuming market data already familiar in the traditional securities, commodities and forex markets.

Earlier this spring we conducted a survey with 170+ crypto traders to understand what they think of analytics built on top of raw market data feeds, an area that we have long speculated to grab the attention of the mainstream crypto traders during 2020. This blog post goes over the main questions and results of that survey. …

Another exciting week behind us! Among the interesting topics Amazon explores military applications of Blockchain technology and Goldman Sachs reverses Crypto policy and angers the community.

Check out them and other selected ones below in our first ever ChainSlayer Weekly Newsletter!

  1. Goldman Sachs reverses crypto policy
    The iconic Wall Street hedge fund Goldman Sachs had an investor call on the 27th this week. In it they issued a statement that cryptocurrencies are not an asset class and a stern warning for risks involved in them. This indicates a change in their policy as they have been known for being one of the first institutions in Wall Street to open a crypto trading desk. …

As a company that works with market data we like to keep our finger on the industry pulse. In the past 6 months we have been talking to well over 50+ crypto hedge funds that focus on quantitative trading strategies and automated trading execution.
In these discussions we’ve obtained amazing insights about what excites and worries them, and what they see the future holding for cryptocurrency trading. This post is the first in a series unpacking these insights.

In our interviews with crypto traders we had an interesting observation when we asked them about how are they are accessing the market data. Most of them told us that they are accessing it with the API integrations that they have built themselves. …

This week has been another turbulent one in the world of Cryptocurrency! Money moving from a wallet that could very well belong to Satoshi, cryptocurrency whistle blowing awards and Visa’s application for a Digital Dollar patent dominated the news cycle among others.

Check out them and other selected ones below in our first ever ChainSlayer Weekly Newsletter!

1. Money moving from Satoshi Nakamoto’s bitcoin wallet (allegedly)

A transaction that originated from a very early bitcoin wallet was recorded this week. It contained the block rewards for a block mined back in February 2009, meaning that it belonged to an early bitcoin adapter, or even to Satoshi (them/him/her)selves. …


At Gardener we provide a free and open source Blockchain Oracle implementation. As the Oracle itself is running on the back end we wanted to create a tool that demonstrates what is happening on-chain when a call is made to Gardener. Below, we explain step-by-step how you can test Gardener through our Monitor!

One still largely untapped use case for blockchain technology is to represent physical objects in a digital form. To convey the information between the physical and digital requires an oracle. In this post, we have a look at an exceptionally interesting use case. One where the objects exist already in physical and digital form but are not connected to each other — the universe of Magic: The Gathering.

Magic: the Gathering (MtG) is arguably the most popular collectible card game in the world. In it, two or more players, or wizards, battle each other in a turn-based card game that is full of magical mystery. …


One of the first use cases of cryptocurrencies, even before Ethereum and smart contracts was gambling. The concept of programmable money goes extremely well with the concept of an online casino. There are many blockchain-based casinos, but they all have one thing in common: the need for open-source oracles.

Blockchain gambling landscape
The online gambling industry is growing rapidly. A 2018 report from Ginar estimates that the size of the online gambling industry will reach approximately $55 billion in 2019. …


This is the second blog post in a series that explains some of what happens under the hood when we want to rely on information that is outside a blockchain.

In the case of oracles, the classification of centralized versus decentralized is somewhat of a misnomer. In this blog post, I argue that there is rather an evolutionary step from centralization to decentralization. We evaluated current blockchain oracle projects to this conclusion.

Centralized oracles
For any oracle to function efficiently, there must be an off-chain entity or node (software, hardware or a combination of both) that facilitates information transfer in and out of the blockchain. Also, ideally this node is secured such that the hardware and software it uses is tamper proof to a reasonable certainty. In its purest form a centralized oracle does exactly that: it functions in a secure manner and through providing data from an external source to the smart contract. …

As decentralized finance grows we’ve seen an explosion in the number of companies that use smart contracts in their business models. Business logic that is deployed on top of a blockchain now governs an increasing number of assets and transactions. Some of that logic, however, depends on receiving information from off-chain sources, such as share and commodities prices. But how can we know if this data is reliable? …
