Let's dive into Ethereum transactions, gas limits, and network capacity.How do transactions work?Transactions are cryptographically signed data messages that contain a set of instructions. They enable the transfer of value and execution of smart contracts. It's a powerful concept that enables users to interact on the Ethereum network. Users initiate transactions through wallets or dApps, which generate a data structure containing the transaction details. The data is signed with the ...

The crypto community is divided over whether the launch of the Ordinal protocol on the Bitcoin mainnet will have a positive impact on the Bitcoin ecosystem. Ordinal NFTs (aka digital artifacts or inscriptions) allow users to mint non-fungible tokens onto Bitcoin's blockchain. Ordinals take advantage of Taproot & Segwit witness data to store JPEGs, videos, games, etc. Ordinal Theory is the fundamental idea behind Ordinals. It allows for the creation of Bitcoin-native digital artifacts, "i...

Bored Ape Yacht Club (BAYC) is a popular NFT collection created by Yuga Labs. In this post, we’ll go over BAYC smart contract code. The source code is available on EtherScan.ERC721BAYC is implemented as an ERC721 token, a standard that defines a set of functions that a smart contract must implement in order to be considered a compliant ERC721 token. These functions include the ability to transfer tokens, approve other addresses to manage your tokens, and check token ownership.ERC721 interface...

NEAR is a Proof-of-Stake blockchain that uses sharding technology to achieve scalability. NEAR uses an election mechanism called Thresholded PoS (TPoS). The general idea is to have a deterministic way to have a large number of participants that are maintaining the network. NEAR's mission is to remove all barriers to Web3 with the goal of onboarding 1 billion users in the first five years. Accounts NEAR accounts have human-readable names (eg. marko.near). Top-level accounts are created by...

Good code is self-documenting. However, adding documentation to the code is well worth it, especially for smart contracts. Let’s see what is NatSpec is and how to utilize it for smart contract documentation. NatSpec is a special documentation format for Solidity smart contracts. While good contracts can be self-documenting, including NatSpec enables developers to easily share and export documentation. The NatSpec format consists of specially formatted comments within the Solidity code. NatSpe...

Are you familiar with the concept of NFT provenance hash? Without a provenance hash, projects have the ability to manipulate the metadata of an NFT to their advantage once the minting process has been completed. The sequence in which NFT tokens are assigned to the metadata is important. If the order of assignment is undisclosed before the mint, buyers of the NFTs have no assurance that the project team will not modify the assignment after the mint to benefit themselves. To address this issue,...

I've noticed that smart contracts can be confusing, even for developers diving into web3. Let's go back to the basics and explore how Ethereum smart contracts are created, deployed, and executed.What are smart contracts?Smart contracts are just programs on the Ethereum blockchain. It's a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain. Data = how many NFTs I have Code = how to transfer NFT from A to BHow are ...

Let's see what it actually does.Transfer eventFirst, let’s take a step back to understand the events and how they are stored. Events in Solidity serve as a mechanism for smart contracts to emit information. They are triggered by functions within the contract and can be monitored by external applications. An event log is a record of an event that has been triggered and recorded on the blockchain in a form of a special data structure. Event logs are a more economically friendly method for ...
