Bitcoin halving is a halving of the reward received by miners. this all happened due to maintaining the number of bitcoins in circulation so as to cope with inflation. This happens every 4 years. roughly happened after mining 210,000 blocks. As for every mining process, there will be new bitcoins from the limited supply of bitcoin, which is 21 million so that the circulation of supply in the market will increase.

The Bitcoin Halving has occurred several times, namely the first time the halving occurred on November 28, 2012, from the first prize of 50 BTC to 25 BTC per block. and 4 years later it happened again on 9 July 2016 from 25 BTC to 12.5 BTC. and 4 years later it happened again on 11 May 2020 from 12.5 BTC to 6.25 BTC the reward earned per block.

So from the previous Bitcoin Halving event, it is estimated that it will happen again 4 years later, namely, in 2024, it is estimated that the prize will be from 6.25 BTC to 3,125 BTC. although the reward from mining always halvings every year, because BTC continues to be mined and is getting rarer, it causes the price of BTC to increase every time this is a very good thing for miners to make profits even though there has been a halving.

And other Cryptocurrencies that have been halved, namely:

• Litecoin, Almost the same as Bitcoin, another Cryptocurrency that halving is Litecoin, Litecoin also experienced a halving from 50 LTC to 25 LTC per block and for now, it has become 12.5 LTC per block.

• Dogecoin, this cryptocurrency has also experienced a halving although only once in 2014 from 500 Dogecoins to 250 Dogecoins per block.

2.) What are consensus mechanisms and how do Proof-of-Work and Proof-of-Staking differ?

The consensus mechanism is a method that runs on the Blockchain which has a function to verify every transaction that occurs. as we all know, every transaction executed by the node will be verified to maintain the authenticity of the data so that the blockchain network is maintained safely.

The Consensus Mechanism aims to provide security and data transparency to the Blockchain network so that all transactions that run and are distributed on the blockchain network run according to the procedures set by the system.

There are many types of consensus algorithms such as Proof of Work (PoW), Proof of History, Proof of Stake (PoS), and others, here we will discuss 2 of them and their differences.

Proof of Work (PoW)

Proof of Work (PoW) is a consensus algorithm on the Blockchain network to verify and validate every incoming transaction. This algorithm requires miners' efforts in the transaction verification process by completing mathematical calculations in each incoming miner's block.

With a Proof of Work (PoW) work system, it is very burdensome for computer equipment so that the electrical power consumed is quite large. In the PoW Algorithm, the competition for miners to complete transactions is very dependent on computer devices with good performance in order to complete cryptographic calculations for each existing transaction. after the transaction has been verified then each transaction will enter the blockchain network in the form of blocks. As for this algorithm, it is quite slow because it takes about 10 minutes to validate transactions.

Proof of Stake (PoS)

Proof of Stake (Pos) is an algorithm that is more developed than Proof of Work. because many of the shortcomings of PoW have been improved so that PoS is growing and getting better. One of the advantages is that PoS is very energy efficient.

Proof of Stake is very dependent on the number of assets owned by miners in the mining process. in the mining process, the miners stake by risking their assets in mining process. so this system is very efficient in the mining process because it can reduce attacks and is certainly more sophisticated without running expensive computer devices or mining machines in the mining process

4.) What is meant by Altcoin Season? Are we currently in Altcoin Season? When was the last Altcoin Season? Mention and show 2 charts of Altcoins followed by their growth in the most recent Season. Reason your answer.

Altcoin Season

Altcoin season is one of those moments when all altcoins experience market price increases simultaneously. As we all know Altcoin is another Cryptocurrency besides Bitcoin. for now, we all know bitcoin dominance is around 40% to 50%. this can be said to be almost half of the dominance of other cryptocurrencies. so when the altcoin season occurs the dominance of bitcoin decreases due to the increasing dominance of other cryptocurrencies.

The altcoin season occurs when many investors are attracted to the growing popularity of altcoins so that investors try to invest in other coins besides bitcoin so that the dominance of Altcoins is increasing in the market. can usually be viewed within a predetermined time interval.

Current Season

Screenshoot from Blockchaincenter

According to Blockchain Center.Net, this month's altcoin Month Index shows a value of 20 and is a Bitcoin month, while the Altcoin Season Index shows 51 this shows that altcoins have started to increase even though they don't show altcoin season. while the Altcoin Year Index shows the number 63 which is in the last year Altcoins are growing rapidly, so it can be predicted that they will enter the altcoin season again.

Last Altcoin Season

Screenshoot from Blockchaincenter

According to Blockchain Center.Net, the last Altcoin season occurred between March 2021 and the end of June 2021. This shows that the altcoin period is quite long, reaching 3 months. Altcoins are able to attract investors.

Altcoin Growth Last 90 days

Conclusion

Bitcoin halving is a method of deducting half of the reward per block, usually, Bitcoin halving occurs every 4 years now the reward for each block has become 6.25 BTC. although the prices are decreasing, the price of Bitcoin is increasing every year this is due to a large amount of BTC that has been mined so that the total BTC is decreasing from the total supply.

Altcoin season is a situation where the price of Cryptocurrencies other than Bitcoin increases, so that during the altcoin season all altcoins dominate the market more than Bitcoin. There are so many altcoins that have the potential to invest because the popularity of altcoins has grown and has attracted a lot of interest from investors in investing.
