Discovering which token standards are supported by a contract
Jim McDonald
Describing the process to understand if token contracts support ERC-20, ERC-721 or ERC-777 by querying registries and testing capabilities.
Understanding ERC-777 token operator contracts
Jim McDonald
Examples of using ERC-777 token operator contracts to extend contract functionality, including code.
Understanding ERC-777 token contracts
Jim McDonald
Explaining Ethereum token contracts in general and the specifics of the ERC-777 token contract, providing details on its features, functions and usage.
Managing ENS domains with Ethereal
Jim McDonald
Registering, managing and using Ethereum Name Service (ENS) domains from the command line with Ethereal.
Trusting identities
Jim McDonald
Exploring the issue of trust in identity in both the real world and cryptocurrencies.
Understanding sparse Merkle multiproofs
Jim McDonald
Sparse Merkle multiproofs provide space-efficient proofs for multiple values in the same Merkle tree. This article explains what sparse Merkle multiproofs are and compares them to pollarding.
Understanding Merkle pollards
Jim McDonald
Merkle pollards are an extension to Merkle trees, providing a significant reduction in the size of repeated proofs in situations such as STARKs where proofs are generated against the same Merkle tree.
