A trusted execution environment, or TEE, is a secure area of a computer’s hardware or software that is used to store and execute sensitive data and code, protecting the sensitive information and code from being accessed by unauthorized parties or modified in any way. A security enclave is a similar…

To popular demand, I have decided to try and explain how the ECDSA algorithm works. We’ve discussed a bit about elliptic curve signatures before and a little bit more after that, but it seems it’s never enough. Admittedly, I’ve been struggling a bit to understand it properly and while I…

In the previous article we’ve discussed about multisig deployment and how it can greatly improve the project’s security throughout the development cycle. Today we’ll discussed even further improvements into key sharing schemes and start with Shamir’s Secret Sharing Scheme (SSSS) Shamir’s Secret Sharing Scheme is related to the broader concept…

Oracles were individuals who were believed to be able to communicate with the gods and provide prophecies and guidance to people. …

Arweave introduces an entirely new economic model to the market, one that was never possible before the advent of permissionless crypto networks: permanent storage. It addresses this by requiring miners to refer to data that was previously stored, proving they still have it. …

Security keys are used almost everywhere within Ethereum during user interactions, and the Ethereum address is derived from the private key. In other words, the Ethereum address is the last 20 bytes of hash of the public key controlling the account with 0x appended in front. How are Ethereum addresses generated? There are three main…

As the number of people using Ethereum has grown, the blockchain has reached certain capacity limitations. This has driven up the cost of using the network, creating the need for “scaling solutions.” There are multiple solutions being researched, tested and implemented that take different approaches to achieve similar goals. The…

Asymmetric cryptography is one of the most important computer science inventions of the previous century. Cryptography is used extensively within Ethereum, and one place that users have contact with it is via Ethereum accounts. As we discussed in the previous article, public key cryptography is based on mathematical functions that…

Non-Fungible Tokens (NFTs) have captured the imaginations of collectors, investors, and tech enthusiasts alike, and if your interest in NFTs and blockchain technology is growing, you will want to learn more about NFT standards. However, before you read more, if you aren’t familiar with NFTs and want to learn more…
