The block size limit, in concert with the proof-of-work difficulty adjustment settings of bitcoin's consensus protocol, constitutes a bottleneck in bitcoin's transaction processing capacity. This can result in increasing transaction fees and delayed processing of transactions that cannot be fit into a block. [ 4 ]
The first hard fork splitting bitcoin happened on 1 August 2017, resulting in the creation of Bitcoin Cash.

Tx_root: root hash value of a hash tree (w:merkle tree) over all transactions. Timestamp: creation time of block, as seen by block creator. The timestamp is checked by other clients and must be within a certain window (tolerates small clock skews). Nonce: any number to make sure the resulting hash value of this block is below the target hash value.

Gox revealed that they had been targeted by an exploit in Bitcoin protocol called "Transaction Malleability". At the time, Mt. Gox was the world's largest bitcoin exchange, handling approximately 70% of all bitcoin ...
A diagram of a bitcoin transfer. The bitcoin protocol is the set of rules that govern the functioning of bitcoin.Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all bitcoin transactions; mining and proof of work, the process to create new bitcoins and verify transactions; and ...
