An indexer is a tool that extracts transaction data from a blockchain node, transforms it into a machine and human-readable form, and loads it into a database or another service for easy querying. Blockchains have a fundamental problem - their data is not searchable. In other words, on-...
Blockchain Nodes: Blockchain blocks of data are stored on nodes—the storage units that keep the data in sync or up to date. Any node can quickly determine if any block has changed since it was added. When a new, full node joins the blockchain network, it downloads a copy of all th...

Blockchain and cryptocurrency concepts can be easily understood if we divide the concepts in two parts: A Block and transaction flow. In this article we will learn how a block is created in a Bitcoin and what are the components of A Block. Blockchain A Blockchain is a decentralized databas...
Once it is entered into a block and the block fills up with transactions, it is closed, and the mining begins. Every node in the network proposes its own blocks in this way because they all choose different transactions. Each works on their own blocks, trying to find a solutio...
This is the final step in securing the ledger. When a mining node becomes the first to solve a new block’s crypto-puzzle, it sends the block to the rest of the network for approval, earning digital tokens in reward. Mining difficulty is encoded in the blockchain’s protocol; Bitcoin an...
And finally, a blockchain is a database that is shared across a public or private network. One of the most well-known public blockchain networks is theBitcoin blockchain. Anyone can open a Bitcoin wallet or become a node on the network. Other blockchains are private networks. These are ...
Unless every single node in the network agrees with a change to a block, the change is discarded. What makes blockchain technology so revolutionary? There are many potential benefits that come with the adoption of blockchain technology. Here are three to consider: Blockchain can drastically ...
In Bitcoin, your transaction is sent to a memory pool, where it is stored and queued until a miner picks it up. Once it is entered into a block and the block fills up with transactions, it is closed, and the mining begins. Every node in the network proposes its own blocks in this ...
