A key to decentralization is imposing constraints on authority. Constraints are used to limit undesired actions of agents in a system forcing them to engage in constructive behavior. When all agents are constrained such that incentives are aligned, trust can be established. With cryptoeconomics we design decentralized protocols which precisely| karl.tech
It's unclear how governments will integrate with blockchains. Historically, governments have gained much of their power through land ownership secured by force. However, as humanity ventures further into the virtual, physical land ownership loses importance. With cheap flights, Airbnb, and widespread internet access we will likely see a| karl.tech
[Cover Image Source] Distributing dividends via smart contracts is difficult with a large number of shareholders. A naive implementation could look something like this: for s in shareholders: dividend = s.shares/total_shares * total_dividends send(s.address, dividend) This is not practical when the number of shareholders is large| karl.tech

Reliance on Javascript is stunting the growth of the Solidity development ecosystem. It’s why new developers get stuck. It’s why we struggle integrating Solidity into development environments. And it’s why much of our documentation is out of date. We are stuck in our Javascript| karl.tech
Understanding how to use testnets is essential for developing smart contracts on Ethereum. Here is a basic introduction to what testnets are and how to use them. What is a testnet? Testnets simulate the Ethereum network and EVM. They allow developers to upload and interact with smart contracts without paying| karl.tech
Getting started writing dapps is hard. You've got a lot of moving pieces, and half of them are in beta release. It's great because you can make a huge impact as an early adopter, but being a pioneer you sacrifice the convince you'll find| karl.tech
