Have you follow the cryptocurrency news recently ? You must be realize that there are many new cryptocurrency projects based on Decentralized Finance or DeFi has been created nowadays. So, do you already know what DeFi is? DeFi is the abbreviation of Decentralized Finance, it is a financial system or platform that created on the decentralized system like blockchain. Usually it refers to Financial platform or dApps in Ethereum blockchain, although it can be created on other blockchain too. To make Decentralized Finance come true, we must using a good system or maybe a decentralized financial firm. When a Decentralized Financial firm created, people can manage their own Financial out of the centralized party. PayPDM Inc is the Decentralized Cryptocurrency Finance firm that providing many financial services on its platform based on the blockchain. Why we need Decentralized Finance firm ? because there are several problems in existing Finance firm. Problems in existing Finance firms Centr...

Do you already have a nice and secure wallet to store your token ? Now, if you want to secure your paper money, you will need to have a secure wallet as well, right ? Like the physical wallet we using, the same goes with cryptocurrency wallet. Unsafe wallet can causing high possibility to be compromised and loss of funds, we don't want that, obviously. What we can do to secure our funds is find a secure wallet. Today, i want to talk about the wallet that we can store our token, ERC20 token safe and secure. Below is the list of some Ethereum wallets which can be used to store tokens. MyEtherWallet MEW (MyEtherwallet) is an online wallet that can be used to generate the Ethereum address and store the tokens on that address. The website of MEW is : https://www.myetherwallet.com/ Usually people who want simplicity and ease of use, will using this wallet to avoid complicated way. The disadvantage of this wallet is the security. As long you visit the real MEW website, you will be good. M...

Good day readers, as you can see now the cryptocurrency market has become more green and i want to share more content about cryptocurrency in this article. If you already read my few previous articles, then you must be already have some knowledge about the Tokenization. To put it simple, Tokenization is a method to convert the assets into token. There are several cryptocurrency coins that has token on their blockchain, but we will stick to Ethereum coin because token is very popular in Ethereum blockchain. Remember when the Bull Run occurred in 2017 end ? It was because many new projects launched their ICO/ITO. ICO/ITO is Initial Coin/Token Offering, it is the mechanism of collect money to funding the project because it is a new project. There are many new projects created because tokenization, they are basically convert their company asset into token and the investors who invest on their project will receive the token which is represent of their share on the project company. The advan...

It is nice to have another exciting day in cryptocurrency world, because new things happens everyday. Today im gonna share the top 3 global hash rate of cryptocurrency coins by its algorithm at the moment. SHA-256 1. Bitcoin - 128++ EH/s 2. Bitcoin Cash - 2++ EH/s 3. Bitcoin SV - 2+= EH/s Ethash 1. Ethereum - 203++ TH/s 2. Ethereum Classic - 2++ TH/s 3. Zilliqa - 19++ TH/s Scrypt 1. Dogecoin - 446++ TH/s 2. Litecoin - 281++ TH/s 3. DigiByte - 11++ TH/s Cryptonight 1. Bytecoin - 205++ MH/s 2. Karbo - 53++ MH/s 3. Croatcoin - 25++ MH/s Equihash 1. Zcash - 5++ GSol/s 2. Horizen - 553++ MSol/s 3. Pirate Chain - 55++ MSol/s That is the current global hash rate power of cryptocurrency at the moment, i hope it will be useful for you. Author : Juice Shen

Ethereum Classic has suffered from 51% attack recently, thus the security of the coin has become very questionable. With this case, everyone must be think that there is a possibility the same thing can be happening in other coin, for example Bitcoin. Can Bitcoin suffer with 51% attack too ? If we look at the global hash rate of Bitcoin network, China has the most hash rate. So China can launch attack on Bitcoin network ? Although we concern about so much hash power concentrate on China, 51% attack on Bitcoin is hard to be done. The attackers cannot steal other people's Bitcoin, change consensus rules, or reversing the valid transactions. The only thing they can do is double spend their own BTC. The most fit scenario is like this : The attacker deposit and sell their own BTC on exchange and withdraw it, and later they just attack and reverse the block which contain their BTC deposit transaction. But the problem is, they will need to provide KYC docs in the exchange they want to with...

We all know that cryptocurrency world is vast and we need some time to understand about it. If you follow my posts, you should understand more about bitcoin now because i talked about what bitcoin is on one of my previous article, when it was created, by who, why it was created, etc. We should explore cryptocurrency more, because we won't be satisfied with just knowing more about bitcoin, right ? Ok now, the most popular cryptocurrency coin is Bitcoin, no doubt, and the second popular coin is Ethereum. Ethereum was created by Vitalik Buterin and team, released in 2015. It has smart contract functionality on the blockchain, enabling the user to use scripting language for developing the application. Token Token is the most often thing we will find on Ethereum blockchain. Although there is token in other coin too, but i believe Ethereum is the first coin that issuing token and other coin using Ethereum base concept to create or issuing the token on their blockchain. We may often hear ...

Back then in late 2017, i was mining Monero with my CPUs and got plenty of profit in no time. Another coins than Monero would be a good choice too because the cryptocurrency market was doing very good. But how about now ? Can we mining cryptocurrency and make profit from it ? Well, it is depends from the crypto market. For me, the current cryptocurrency market is better than last year because crypto market starting to rising now. You can see on coinmarketcap.com that the market capitalization of cryptocurrency is increasing, particularly on top coins such as Bitcoin and Ethereum. Bitcoin halving has occurred few months ago, the block reward gone from 12.5 BTC to 6.25 BTC per block. For miners, of course halving is not a good thing because their mining profit will be cut half. The price of Bitcoin need to doubling so the miners can make the same profit from before halving. We was expecting that Bitcoin price will increase after halving, but it was not happening, although Bitcoin price i...

As a crypto-enthusiast, do we know what Bitcoin really is ? Let me give some explanations about it for us. Bitcoin and Blockchain First, the definition, Bitcoin is an electronic peer to peer payment system and it was created by Satoshi Nakamoto in 2009. Second, why Satoshi Nakamoto created it ? It is because there was financial crisis / trust issue happening on banks in the past. The centralized party like banks force people to trust the bank to control their money. Satoshi Nakamoto Does Bitcoin solve the problem ? Yes it is. With Bitcoin, people have other option than using banks to manage their money : using Bitcoin. The nature of bitcoin is decentralized because there is no central point like banks, so there are nothing to monopolize the money or control it centrally. Bitcoin using Blockchain technology to running the network, it is like a big ledger of all transactions in the network. So what is Blockchain ? To put it simple, it is a series of blocks, which every blocks has the det...

It has been 5 years since Ethereum was created. Now the coin has became a great coin, the second most valuable and popular coin in cryptocurrency. Ethereum 1.0 is a Proof of Work coin, same as Bitcoin. It requires hash power to mine it so we need some devices like ASIC miners or GPU cards to mining the coin. Different with Bitcoin, Ethereum using Ethash algorithm on it's network. In Ethereum 2.0 - named Serenity, it will move from Proof of Work to become a Proof of Stake coin. In other words, we won't be able to mine with ASIC or GPU anymore. Instead mining with devices, we can mining by staking our coin into the network, the validation on network won't rely on computing power anymore. The update of Ethereum 2.0 will improve energy efficiency because no large amount of electricity needed to mining the coin. The long awaited Ethereum 2.0 may complete in 2021. Now is the phase for testing the network on testnet. Ethereum price has showing a significant changes in the market, ...

Do you remember the article i posted about Ethereum Classic 51% attack last week ? Here :  https://cryptojuice.blogspot.com/2020/08/51-attack-on-ethereum-classic-network.html Today, Etherchain.org posted a tweet and stated that the affiliated mining pool Ethermine had disabled ETC payout after 4000+ blocks had been reorg-ed in the latest attack. It is still unknown if the attacker is the same person with the first one or not. Last week, the hacker reaped about $192,000, it is 2,800% ROI from renting hash rate from NiceHash. 51% attack can be initiated on Ethereum Classic using rented hash rate power from NiceHash for just $12028 / hr. The attacker was double-spending 807,260 ETC, worth about $5,6 million. In other words, Ethereum Classic network security is very questionable. Anyone who understand about 51% attack could rent the hash rate to attack the network. Maybe it is better for Ethereum Classic to become a PoS coin like Ethereum update ?

DeFi DeFi and DeFi, maybe you read those words more than before nowadays. Well, of course we want to use our money without additional fee charged by middle man, intermediaries, or some third parties. It means we own 100% of our money and have full control of it, that is Decentralized Finance in a nutshell for me. Before we proceed further, let me take you to the past for a short moment. In the past, people were using the very primitive way to get what they need, or they want, that were goods. For example, to obtain meat from others, they need to trade their rice for other's meat, it means goods with other goods. This method is not optimal because sometimes difficulties come when people trying to measure the value of the goods. Later, they started to using precious metal such as gold to trade each others. Then, people have made money. Money is a currency and it is like a universal tool for measuring value of any goods. Paper money is very convenient because people can carry it with...
