Curated writing on money, crypto, investing and much more - using terms that you'll actually understand.
A blockchain stores verified information in chronological blocks linked by cryptographic hashes. Copies are distributed across network nodes, making records transparent, difficult to alter and less dependent on a central authority. Public and permissioned versions support cryptocurrencies, smart contracts, supply chains, property records, farming and other industries that benefit from auditable shared data.
Cardano approaches smart-contract infrastructure through peer-reviewed research, a layered architecture and an energy-efficient Proof-of-Stake system called Ouroboros. Separate settlement and computation layers support payments, applications and lower congestion. ADA pays fees, secures the network through staking and is intended to give holders a voice in Cardano’s evolving governance.
Cryptocurrency is digital value secured by cryptography and typically maintained through a decentralised blockchain rather than a central bank. Transactions move between wallets and are verified by miners or validators, depending on the network. The ecosystem spans payment coins, stablecoins, utility assets, DeFi tokens and NFTs, each carrying distinct benefits and risks.
Cryptography protects information by converting it into a form that only authorised parties can interpret. In cryptocurrency, public and private keys use this principle to prove ownership, sign transactions and prevent unauthorised spending. Digital signatures verify that the correct wallet owner approved a transfer without exposing the private key itself.
Decentraland is a blockchain-based virtual world where users can explore, build and trade digital experiences. LAND represents parcels of virtual property, while MANA serves as the ecosystem’s native currency for purchases and participation in governance. Together they underpin a user-owned metaverse economy spanning real estate, events, games, collectibles and social spaces.
The Tap card gives you as much as 8% cashback to let you earn more on your everyday spending. No credit check required.
Decentralised finance recreates services such as lending, borrowing, trading and interest-bearing savings through blockchain smart contracts rather than banks. Anyone with a compatible wallet and internet connection can participate, often across borders and around the clock. Greater access, transparency and speed come alongside technical complexity, limited consumer recourse and regulatory uncertainty.
Dogecoin started as a joke. Then Elon got involved and it became a top crypto. Here's how this meme coin actually works and the story behind it.
