First, you'd need to control 51% of the validating nodes to alter the blockchain transaction. Secondly, ETH's design enhances its resistance to tampering and fraud due to the threshold it sets for one to pull off such moves. That's a pretty pricey sum to pay for someone with dubious intentions on the network. First, one would need a stake of 32 ETH (currently around $42,000) to become a validator. Ethereum’s Answer to PoS CentralizationĮthereum has made provisions to mitigate possible centralization of the validation process. This could have negative consequences for the security and stability of Ethereum. If a small number of entities are in control of validation, they could work together to game the system and reap greater rewards. Such actions would severely undermine the transparency and censorship resistance of Ethereum.Īnother concern is that a centralized validation process could lead to collusion amongst validators. If a small number of entities control the validation process, they could choose to block certain transactions or even entire blocks from being added to the blockchain. One issue with a centralized validation process is that it could lead to censorship. This means that those who hold more coins have a greater chance of being selected to create a new block and earn rewards. ![]() Under PoS, validators are chosen to create new blocks not based on how much computing power they have, as is the case with Proof-of-Work (PoW), but on how many coins they have deposited into a smart contract called a staking pool. PoS, on the other hand, is more scalable and efficient than PoW, making it better suited for a large-scale network like Ethereum's. PoW could no longer handle the load, resulting in high transaction fees and long wait times for transactions to be confirmed. Why the Shift to PoS?Įthereum’s growing popularity led to increased congestion on the network necessitating the switch to PoS. Kraken (8.62%) and Binance (6.68%) are the other two exchanges with significant shares of staked ETH. Lido's total stake is 30.5% of the total, while Coinbase's is 14.6%. In 2018, the cryptocurrency reached a market capitalization of 2 billion USD.As of September 16th, Etherscan reports that Lido and Coinbase manage a combined 45% of all staked ETH. in 2015, Jackson Palmer withdrew from the project since he didn’t want to be associated with a fun currency with a high market capitalization. ![]() The cryptocurrency already had a market cap of 60 million US dollars at that time. In February 2014, the first Dogecoin machine was installed in Vancouver and a few months later 2 Bitcoin machines in Tijuana also started supporting Dogecoin. ![]() Two months later, the stolen credit was completely replaced for the victims and this was a strong sign that the community is very strong as well. However, the community was strong and launched an appeal for donations. Just a week later, Dogecoin had its first hack and millions of the coins were stolen from the online wallet DogeWallet. One of the reasons for this was that the Chinese Bank was no longer allowed to trade with Bitcoin and the miners took advantage of the fact that Dogecoin (DOGE) had little mining difficulty. On December 19, 2013, Dogecoin increased up to 300 percent in less than 3 hours and only a few days later the cryptocurrency lost about 80 percent of its value again. However, the cryptocurrency quickly found many fans on the platforms like Reddit and the amateur-style of the altcoin became its trademark. The homepage of Dogecoin (DOGE) was written in Comic Sans and the videos were made amateur-style. This was very clear once you entered the homepage of the altcoin and the videos for it as well. In the beginning, it was openly stated that this cryptocurrency is made only for fun. Shortly after the launch, he was supported by Jackson Palmer who brought domain. ![]() Dogecoin (DOGE) was launched in 2013 in December as a fun currency by the only programmer at that time Billy Markus from Portland Oregon.
