Blockchain: A blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. It is a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Decentr...
Blockchains can be public or private. In a public blockchain, anyone can view the ledger and participate in the consensus mechanism. In a private blockchain, the consensus mechanism is restricted to certain nodes on the network, and views of the private ledger may also be restricted.Hybrid b...
On-chain governance is the more recent iteration of governance in blockchains and brings with it some fascinating and polarizing concepts. So far, many of the on-chain governance implementations have either just launched or not even launched yet. On-chain governance solutions for blockchains prima...
For example, a computer can become a network node that communicates with all other devices on the network. It can synchronize with the entire network and store the full history of the blockchain, starting from the first block. Such a computer is called a full node. Full — because it stor...
First, a blockchain database must be cryptographically secure. That means you need two cryptographic keys to access or add data on the database: a public key, which is basically the address in the database, and the private key, which is an individualized key that must be authenticated by ...
What good is a safe, dependable, smart contract on the blockchain if the data it relies on is suspect? This problem is solved by Chainlink (a decentralized network of nodes), which uses oracles to provide data and information from off-blockchain sources to on-blockchain smart contracts. ...
Blockchain began with Bitcoin as a store of value and evolved with smart contract platforms like Ethereum, enabling decentralized applications and more versatile use cases. Bitcoin focuses on security and immutability, while layer-1 (L1) chains like Ethereum and Solana and layer 2s (L2s) prior...
Solana is technically still in beta. This isn't uncommon for blockchain projects, nearly all of which are experimental in at least some regards. But it's worth noting that a project is in beta if you're going to invest, or build an app on the platform. ...
Have you ever wondered, what is blockchain tokenization? Tokenization has been around for a long time and now has a new use case with crypto.
Solana is much faster in terms of the number of transactions it can process and has significantly lower transaction fees than rival blockchains like Ethereum. The cryptocurrency that runs on the Solana blockchain—also named Solana (SOL)—soared almost 12,000% in 2021 and, at one point, had...
