簡單來說,比特幣減半就是挖礦獎勵減半(減少50%)。比特幣的稀有特性會影響價格,有很多人將這次的減半視為另一個價格的轉捩點。最值得留意的是,比特幣的產量是像黃金一樣稀有

目前預計比特幣減半將會在香港時間5月12日晚上進行,但因為每一個區塊的開採速度都不一,所以仍未能確定準確時間。

當減半完成時,每個區塊可以開採的比特幣數量將從每個區塊的12.5 枚比特幣變為6.25 枚比特幣,即代表每天開採的數量由每天約1,800 枚減至 900 枚。所以比特幣的產量越少,它就會越稀有。

減低比特幣的沽售壓力

由於開採的收穫減少,比特幣礦工會拋售比特幣的可能性較低,所以沽售壓力將大大減少。從目前的情況來看,礦工每天要開採價值13,000,000美元的比特幣。這使比特幣礦業成為一個價值數十億美元的產業。


The single most important issue currently facing the Ethereum network is scalability. The Ethereum network supports hundreds of decentralized applications. This means it needs to process a high number of transactions per second. In a recent speed test, the network only managed 20 transactions per second. By comparison, Visa’s maximum capacity is close to 24,000.

A longer term issue is the sustainability of Proof of Work (PoW) and mining. Because each transaction on the Ethereum network uses about 30 kWh (Kilowatt hours). Furthermore, the electricity used by Ethereum mines could power over 650,000 American households every year.

Decentralized Finance (DeFi) has garnered popularity and grown into one of the biggest sectors in the crypto space. According to DeFi Purse, over 500M USD is locked in DeFi applications. Applications include stablecoins, DEXs, lending, derivatives, payments, etc. DeFi is usually referred to as Open Finance, which aims to remove restrictions that limit people’s access to traditional financial services.

The Network

Cosmos, built on Tendermint Core, is designed to be the “Internet of Blockchains”. The network provides the means for trustless exchange of assets across independent blockchains. Exchange occurs via a master hub chain known as the Cosmos Hub.

Cosmos also comes with a toolkit called the Cosmos-SDK. This provides plug-and-play modules for developers to easily create custom blockchains.

Consensus on the network is formed through the Tendermint BFT engine. Various advantages include:

– High Performance: Blocktime on the order of 1 second. Capable of handling thousands of transactions per second.

– No Forks: A property of the Tendermint…

Most cryptocurrencies are volatile as we often see a 10% move for the price of Bitcoin or Ethereum on any given day. To better facilitate practical transactions for good & services and store of USD value, several stablecoin projects were launched.

A stablecoin is a cryptocurrency that is designed to minimize price volatility by being pegged to another asset such as the U.S. dollar or gold. However, most asset-backed stablecoins are considered to be centralized as the collateral (underlying asset) is controlled and managed by the issuer of the coin (centralized body).

There are three main advantages of using stablecoins:
