The Bitcoin (BTC) network has produced its 800,000 block since its inception in 2009, with just 40,000 blocks left to mine before the network’s next mining reward halving.
The 800,000th block contained 3721 transactions at 1.64MB, with the price of BTC trading at $29,815 on July 24, as market researcher Dylan LeClair noted on Twitter:

The milestone was widely shared across the social media platform on July 24, with Bitcoin proponents and industry commentators highlighting the milestone as an indicator of network security and resilience:
The #Bitcoin network just produced block number 800,000.

Bitcoin’s block height at its core is a measure of the sequential blocks of the blockchain, which contain transactions and data that are bundled into blocks by network miners. Block height also serves as a measure of a specific block in relation to the genesis block, the founding block of the network’s chain.

The metric acts as a chronological order of transactions and blocks of the network, with each new block connected to the previous one in the chain. This assists in allowing users to identify the order in which transactions are recorded.
Block height also serves as a measure of Bitcoin’s immutability. The more blocks added to the chain, the more computing power will be required in order for a malicious actor to attempt to tamper with previous blocks.

As previously explored by Cointelegraph, a 50 percent attack would require an attacker to acquire enough computing power to recalculate the proof-of-work of every subsequent block of a tampered transaction-containing block.
Block height also serves as a measure used to maintain Bitcoin’s mining difficulty. Proof-of-work based blockchain networks have their mining difficulty of mining adjusted periodically based on the total computational power of the network and the time it took to mine a certain number of previous blocks.
