Are Off-Block Chain Transactions Bad for Bitcoin?

Bitcoin was designed to be a decentralized and trustless payment network - with the power to do this provided by the block chain and its ability to publicly confirm the digital currency's digital transactions. Rather contentiously, however, as the bitcoin economy expands, more and more transactions are being carried out off the block chain. Such transactions are tracked on private databases instead of the block chain, and cannot be publicly tracked. There are pros and cons to both systems. So, which are better? Off-block chain or on-block chain transactions? Visible payments. Legitimate....

Are Bitcoin Zero Confirmation Transactions Safe?

Transactions are committed to the block chain about every 10 minutes. Zero confirmation transactions do not reside in a block yet. Instead, they reside in the memory pool of miners. Until a block is mined that includes the transaction, it is said to have 'zero confirmations.' Once included in a block and written to the block chain the transaction has one confirmation. Confirmation time is a measurement of a transaction's depth or age, in the block chain; the higher the number of confirmations, the older the transaction. When transactions are first broadcast to the network, they are zero....

Block Parsers: How to Read the Bitcoin Block Chain

A Block Parser reads the Bitcoin block chain. There is no encryption of the data stored in the block chain. Bitcoin is a pseudonymous system. Meaning, ECDSA key pairs are used to abstract the identity of users. However, the binary data in the block chain can be read. The block chain is a transaction database. Every full node participating in the Bitcoin network has the same copy. The Bitcoin protocol dictates its structure and is the means through which each node maintains a duplicate copy. Overall, the block chain is just a data structure for storing blocks. The block chain stores blocks....

He is also the co-author of one of the earliest academic papers to study the network properties of the block chain and its implications for anonymity. The block chain is a decentralised, consensus-driven ledger of every successful bitcoin transaction to date. As of the 300,000th block, the ledger includes over 38 million transactions. Aside from being a monumental technical achievement, the block....
