Blockchain
Blockchain is an emerging technology that can radically improve banking, supply chain, and other transaction networks and can create new opportunities for innovation. Businesses contain many examples of networks of individuals and organizations that collaborate to create value and wealth. These networks work together in markets that exchange assets in the form of goods and services between the participants.
Blockchain technology provides the basis for a dynamic shared ledger that can be applied to save time when recording transactions between parties, remove costs associated with intermediaries, and reduce risks of fraud and tampering.
Annual Hash Growth: Growth in the total network computations over the past 365 days
Block Height: The total number of blocks in the blockchain
Block Interval: Average amount of time between blocks
Block Size: The storage size of each block (i.e. megabytes)

Hash Rate: The number of block solutions computed per second by all miners
Market Capitalization: The market value of all bitcoin in circulation
Metcalfe's Law - TX: A variant of Metcalfe's Law in which price is divided by n log n number of daily transactions
Metcalfe's Law - UTXO: A variant of Metcalfe's Law in which price is divided by n log n number of unspent transaction outputs
Miner Revenue Value: The amount of dollars earned by the mining network
Miner Revenue: The amount of bitcoin earned by the mining network, in the form of block rewards and transaction fees
Money Supply: The amount of bitcoin in circulation

UTXO Growth: The net number of unspent transaction outputs created
UTXO Set Size: The total number of unspent transaction outputs
Average UTXO Value: The average dollar value of each uspent transaction output
Velocity - Daily: The proportion of the money supply transacted each day
Velocity - Quarterly: The proportion of the money supply transacted each day, computed on a rolling-quarter basis
Velocity of Money: How many times the money supply changes hands in a given year
微处理架构——处理复杂事物
许多公司，比如Amazon、eBay和NetFlix，通过采用微处理结构模式解决了上述问题。其思路不是开发一个巨大的单体式的应用，而是将应用分解为小的、互相连接的微服务。
一个微服务一般完成某个特定的功能，比如游戏玩家账号管理、游戏道具管理等等。每一个微服务都是微型六角形应用，都有自己的业务逻辑和适配器。一些微服务还会发布API给其它微服务和应用客户端使用。其它微服务完成一个Web UI，运行时，每一个实例可能是一个云VM或者是Docker容器。
