Groestlcoin September 2019 Development Release/Update!
For a more interactive view of changes, click here In our current world; bordering on financial chaos, with tariff wars, Brexit and hyperinflation rife, you can count on Groestlcoin to consistently produce innovation that strikes to take the power away from the few and into the many, even after a full five and a half years of solid development. Here is what the team has already announced in the last 3 months since the last development update:
Groestl Nodes aims to map out and compare the status of the Groestlcoin mainnet and testnet networks. Even though these networks share the same protocol, there is currently no way to directly compare these coins in a single location. These statistics are essential to evaluate the relative health of both networks.
Shows Onion (Tor) nodes
Shows IPv6 nodes
Supports both main net and test net
Node Checker – Check the status of a remote node
Ability to download node data by CSV, JSON or TXT format
Ability to download unique address data by CSV, JSON or TXT format
This is a tool for creating unsigned raw Groestlcoin transactions and also to verify existing transactions by entering in the transaction hex and converting this to a human-readable format to verify that a transaction is correct before it is signed.

Improved package download progress bar
Added support for external storage access > Android M
Added support for Android Oreo, including new notification mechanism
Bump Fee (RBF) improvements – Implemented a new fee-bump strategy that can add new inputs, so now any transaction can be fee-bumped. The old strategy was to decrease the value of outputs (starting with change). We will now try the new strategy first, and only use the old as a fallback.
Coin Choser improvements
More likely to construct transactions without change (where possible)
Less likely to construct transactions with really small change
Only spend negative effective value coins when beneficial for privacy
Fix long-standing bug that broke wallets with >65k addresses

Slack name: bamber Q1.1: In a retail clothing shop customers often pick up items and return them to the wrong rails. When a member of staff then resets these items the system would log them, skewing the grab rate data. What have WaltonChain done to solve this issue? Answer: Waltonchain’s solution with its unique RFID-based hardware tracks not only clothes but customer picks. Data from different readers (shelves, fitting rooms, price scanners, checkout counters, etc) is aligned and verifies each other. The sequence of RFID reads are time-aligned for interpretation of user behaviors and interests.
Q1.2: Do the RFID clothes rail scanners work on circular rails which are popular in clothing shops? Answer: Technically, yes. Practically, we are further testing and improving performance for the most popular environments and scenarios in the clothing industry.
Q1.3: Items of clothing which are neatly folded and displayed in piles (e.g. jeans) present challenges in terms of placement of RFID scanners. How does the Waltonchain system overcome this? Answer: Okay, we see where this question is coming from: You are asking this because you have not realized the fundamental difference of the RFID tags we use vs. some of the NFC tags you’ve seen out there. This is a good question. Let me elaborate a little, and take this opportunity to give a basic RFID 101. For basics, you should just remember that RFID is the process by which items are uniquely identified using radio waves. RFID tags/chips are the hardware chips that in everyday use people usually refer to as “RFID.” This is fine in daily speech. On a very high level, to make it simple, there are two types of RFID chips we see in the Blockchain world:
Ultra High Frequency (UHF) RFID tags, which operate in 856 MHz to 960 MHz frequency ranges; and
High Frequency (HF) Near-Field Communication or NFC tags, which operate in 13.56 MHz frequency ranges (these tags can be read by your phone. Recently iPhones have implemented this capability.)
Both of these chips are categorized as RFID tags, under the RFID family. The difference in these tags are tldr, but the takeaway for our case is this: Our Waltonchain-compatible UHF RFID chips are readable 9 feet away, in a batch, all at once. NFC chips are usually used in peer-to-peer, i.e., using your phone to scan an NFC chip in very close proximity (a couple of inches or closer). If you watched our demo video made by Boxmining on Youtube, you will notice that we use UHF RFID (Ultra High Frequency) technology. Finally, to answer your question, with UHF RFID system and the Walton RFID reader, we will be able to read with 100% accuracy the tags within a pile of clothes, neatly folded or not.
Q1.4: In a clothing shop can staff manually amend the blockchain data? (if activities in the store results in skewed data - e.g., a large number of items being mistakenly moved resulting in artificial grab rate data etc. can anything be done by the staff to correct this? Answer: Nobody can tamper with data on blockchain. Our specially designed RFID end devices collect data and record on the chain automatically and reliably. At the same time, data analytics can be used to interpret employee behavior as well.
Dominique @DomFromParis Nov 18 Q2: Can you confirm it will be 5000 Walton for a masternode and what % will be paid to the holders? Answer: Yes, holding 5000 WTC qualifies a node to be a Masternode, which will earn extra rewards for every mined block. The percentage and/or reward system will be announced with other details. Please follow our official announcements.
Sam Lyons @SamTaweets Nov 18 Q3: AskWTC If possible can you please tell us if you have any partners already secured for the RFID when you go live on-chain? Answer: As you will have seen from our blog posts and various news articles we have several close partners and have signed strategic cooperation agreements with a number of organisations. We released news of one just last week. Many of these companies have already been using our RFID technology and all have projects planned for RFID + Waltonchain integration. In terms of ongoing discussions, we will not release specific information about them until they are 100% confirmed.
Dominique @DomFromParis Nov 18 Q4: Why Walton does not have a GitHub? Answer: We will have a GitHub. We will provide the GitHub for our full node, light node, wallet, etc. We want everything to be thoroughly tested before public access. Also, our software rollout has to be aligned with hardware R&D.
Peter Peterson @Hamster10Peter Nov 18 Q5: Binance is a good exchange but is it manipulated by trading bots to keep the price unnaturally low. When will WTC be listed on Bittrex or Bithumb? We really need one of the biggest exchanges so our beloved coin can grow naturally. Answer: We have been discussing cooperation with many well-known trading platforms. Please pay attention to our official announcements.
Sam Taylor @chunkylover199 Q6:What is to stop someone simply removing a tag and leaving the tag on an adjacent item of clothing on the rack in order to steal a piece of clothing? Answer: We are developing many different ways to integrate the RFID tags into products. We will make it difficult to remove a tag without damaging it, or the host. In the case of clothing, tags do not have to be attached. They can be printed, woven or sewn into the article itself.
Derek Chow @maseradee Nov 18 Q7: Are there any mechanisms in place to stop someone cutting off the RFID tag from a clothing article and walking out? Answer: It is difficult to develop a perfect theft deterrent system. The methods currently used by shops can deter a portion of the thefts. Additional developments like sewn-in tags will increase deterrence. Also, our RFID tags are not always able to be cut. Wait and see.
Rational Riddler Q8: Will businesses using Waltonchain need to run masternodes or will the unique Waltonchain hardware provide all the mining a business needs? How many readers/scanners will your clients need per store to properly implement the system? #askWTC $WTC Answer: We aim to provide a fully automated solution with complete software and fully-capable hardware. In doing so, businesses that adopt the Waltonchain system can focus solely on their day-to-day requirements without concerning themselves with those aspects covered by the Waltonchain system. Our entire ecosystem scales up with businesses as child chains are created. We want to make it as easy as possible for our partners’ businesses to fulfill their growth potential.
wtcrfid @wtcrfid Nov 18 Q9: AskWTC What hardware will I need to run my 5,000 WTC masternode? Will a RasberryPi type system suffice? Answer: While a RasberryPi could be capable of running a node, It would not be ideal. Please wait for our news on the mining hardware needs.
Sergey @CryptovalleyOF 20 hours ago Q10: Most of the community is concerned about the relation between the price of a token and the blockchain system, what will a WTC token will be equal to? 1WTC= 1000 Transactions? 1WTC=18,000,000,000,000,000 transactions? I would love to hear your response. Answer: The transaction exchange rate is established by the marketplace, not by Walton.
Syed M Mujahid @smmujahid Q11: Walton Chain system essentially include RFID tags, Scanners and blockchain application that will be customizable according to business needs. According to you, tag might cost around 5 cents, what about each scanner and the application. Will it be viable for small businesses Answer: Our definition of an affordable system is twofold: 1) something that provides long-term additional benefits and 2) something that is worth its cost. The Waltonchain system has been tested in industry and has yielded positive results that our clients did not expect. One example is an increase in distribution efficiency of nearly 100%.
Lemuel Wong @2BitsCrypto Q12: Will it be possible to use Walton Chain RFID technology in Luxury handbags, such as Hermes for example, to verify it as an authentic item that is recorded in the blockchain? Or can RFID chips be copied/replicated? Last thing are your RFID chips EMP proof? Thank you Walton team! Answers: Yes, verification of authenticity is a very basic use case. Our RFID chips can not be copied or duplicated. EMP proof RFID chips are not an immediate concern, but are absolutely within the scope of our research and development.
Sergey @CryptovalleyOF Q13: One of the main concerns I have about the Waltonchain project is what will happen when the new wallet and blockchain becomes publicly available. I'm sure there will be lots of scams and fake websites claiming to be Waltonchain - what will you do to ensure that the changeover is as safe as possible? Answer: Security has and always will be among our highest of priorities. This is primary in our system design and deployment but also in ensuring the trust of our community. Official announcements will be made to assist in the transition from ERC20 tokens to official WTC coins.
Errrrr_pesillo @pablo_melo7 Nov 18 Q14: How do you plan to compete with an RFID solution on the IOTA network in future with no mining fees? (Assuming IOTA delivers on their promise) #askWTC #AskWTC Answer: Our RFID system includes a revolutionary RFID readewriter that not only communicates with tags but also performs the task of mining.
Rami Yousif @ramiyousif91 Nov 18 Q15: Is there any upgrade for your website? #AskWTC Answer: Yes, there will be an upgrade to our website moving forward. Please watch for our official news release.
matthew collins @mineu999 Nov 18 Q16: Why was there a QR code on the blockchain demo product and will it be there for the final production model? #AskWTC Answer: Through our network of pioneer users, we are constantly evaluating and refining the production model design. Many aspects may change and many may remain the same. This all depends on feedback from our case-study clients.
Collin @CollinsCustomIP Nov 18 Q17: Please address the wabiico competition & specifically describe how your patents protect your specific (hopefully novel) RFID technology. #askWTC #bitcoin #btc #usecase #blockchain #rfid Answer: The Waltonchain system starts at an integrated circuit level and will be incorporated directly in the manufacturing of electronic devices and products. At this stage, no human interaction occurs—thus the chain of authenticity begins. We can also integrate our RFID technology at higher levels in the manufacturing/supply chain, such as in packaging, as other competitors might. Our patents and IC RFID designs incorporate technology not seen in the RFID space before.
Tristan Maunder @WTCTricky Nov 18 Q18: #AskWTC For masternode holders... Are we going to be able to store our WTC on a hardware type wallet for security? "cold staking" Answer: At this stage we cannot say with 100% certainty that “cold staking” will be implemented. We hope to work with vendors like Ledger and Trezor to implement “cold staking.”
Hello! My name is Inna Halahuz, I am a sales manager at Platinum, the largest listing service provider for the STO and ICO projects. We know all about the best and most useful STO and ICO marketing services. By the way, we developed the best blockchain platform: [Platinum.fund] (https://platinum.fund/sto/) We also created the UBAI, the unique educational project with the best and most useful online courses. We not only share our knowledge but also help the best graduates to find a job! After finishing our courses you will know all about crypto securities, ICO and STO advertizing and best blockchain platforms. What a Blockchain Wallet is? What is its purpose? Find the answer after reading this article. Public/Private Key The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver. Accessing wallets Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals. Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets. Types of Wallets & Storage Methods The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners. Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens. Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples. Hardware wallets — LedgeTrezoAlternatives Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers. Paper Wallets Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper! Real World Historical Examples of Different Wallet Types Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops. Neon Wallet The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible. Real World Example — Poor Practices MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets. In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes. Case Study: Good Practice Binance, the Attempted Hack During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt. Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange. Hardware Wallets Advantages and Limitations We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations. Paper Wallets Advantages and Limitations Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever. Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose. You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait. How to Monitor Funds There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor. That’s not all! You can learn how to transfer and monitor the funds in and out of your wallet by clicking on the link. To be continued!
