HBAR’s Crazy Transaction Stats

It all started with a tweet: Wow, a big claim. It’s been a big year for ETH, but HBAR is 4 times more? What gives? By far the biggest source of transactions are from the Hedera Consensus Service. From Dragonglass, HBAR’s explorer: So what is this ” Consensus Service” anyway? According to Hedera’s own website:Continue reading “HBAR’s Crazy Transaction Stats”

Ethereum Mining

The crypto server has been running for 6 months and things have gone almost to plan. The server specs were basically designed for Filecoin but there were many issues with installing it (see here). We are at the stage where the Filecoin miner needs 1TB to run. Since the 2TB SSD has been partitioned, anotherContinue reading “Ethereum Mining”

Staking Update March 2021

The server rack has been built and various chains are up and running. I’ve been meaning to document what has been built as it has been running for a few months now (the rack was built towards the end of 2020 and hasn’t changed since). The specs: Rack: StarTech 25U (130cm x 88cm x 47cm).Continue reading “Staking Update March 2021”

Building a Cardano Pool using an Air-Gapped Raspberry Pi

When building blockchain servers, it is essential to build an air-gapped server (or “cold environment”). It is easy to be lazy in this area and not bother (especially if you are in a hurry), but this is a requirement rather than a nice to have. Here’s the why/what: Protects against key-logging attacks, malware/virus based attacksContinue reading “Building a Cardano Pool using an Air-Gapped Raspberry Pi”

Building a Staking Server – What to Stake?

I’ve been spending a lot of time investigating staking as a passive form of crypto income. Yes, I’ve had a big stint with Uniswap and put some BitCoin with BlockFi. I haven’t done yield farming unless Ampleforth counts. With staking there are essentially two options – give your crypto to somebody else and they willContinue reading “Building a Staking Server – What to Stake?”

The Problem with Tron

Tron came into prominence recently when its price hit around $0.047 after being below $0.02 for most of the year and was likely due to the news of Tron 4.0 being released: So this is great even after the recent altcoin crash and Tron is definitely worth look at. The question we are asking isContinue reading “The Problem with Tron”

Using the Uniswap V2 SDK

In this post we’ll be using the Uniswap SDK to do a swap between Ether and DAI. This was done in an earlier post here. However this was using Uniswap V1 and there is now an SDK for Uniswap V2 which we’ll look at. The first thing we’ll do is use a forked version ofContinue reading “Using the Uniswap V2 SDK”

Calculating Uniswap Fees

Uniswap is one source of passive income in the Defi space, but how are those returns worked out? How exactly do you make passive income from Uniswap? And what exactly is an impermanent loss? Can you make a loss with Uniswap? It recently became important because of the price of Ether has gone crazy ofContinue reading “Calculating Uniswap Fees”

Ethereum’s Crazy Ponzi Schemes

https://ethgasstation.info/ is interesting in that it shows the biggest generators of gas fees on the Ethereum network. It is also interesting to see how many of them are Ponzi schemes. The biggest at #2 is Forsage (yes, you can argue that Tether is a Ponzi scheme as well) . As I was writing this, EthContinue reading “Ethereum’s Crazy Ponzi Schemes”

AAVE FlashLoan Test Framework

In this tutorial, we’ll be playing with Aave’s ability to do flashloans. Flashloans are described on the Aave website here. This project was initially created using Aave’s truffle box template: truffle unbox aave/flashloan-box The contracts we’ll going to be using will be mostly unchanged from the unboxing. We’re going to try and see if weContinue reading “AAVE FlashLoan Test Framework”
