How much does it cost to develop a cryptowallet for business?

How much does it cost to develop a cryptowallet for business?
A cryptocurrency wallet is specific software that allows you to make global non-cash payments and keep your profit securely stored. There are multiple reasons why business owners switch to cryptocurrency wallets such as no government invasion, multi-currency operations, quickness, no physical currency involved. However, it is necessary to develop your personalized wallet if you want to scale your business and simplify financial transactions. In this article, we will discuss what is the average price of cryptowallet development and how it will benefit your business.
https://preview.redd.it/wxe1e9l5n5r51.jpg?width=2508&format=pjpg&auto=webp&s=5c0b9b94aba2bfe8f877b7aa3f27a0f0592ab5ce
Firstly, it is important to understand the necessity of cryptowallet for entrepreneurs:
  • some transactions require a long waiting period and verification in the bank:
  • high fees on international transactions and unprofitable currency exchange rate;
  • lack of privacy, since online money transfer through a bank is impossible without the provision of personal information;
How does cryptowallet work?
  • fast and secure transactions carried within a few minutes;
  • private keys are safely stored and the transaction is processed between blockchain network members:
  • transaction fees are relatively low in comparison with a bank;
  • a completely anonymous environment;
You should keep in mind a few things that will influence the cost before the development process
Wallet type
There are two main wallet types: the desktop (installed on the PC) and the mobile app that can provide users with constant access to their funds.
Bitcoin libraries
You can either create a cryptocurrency wallet using one of the libraries (e.g. Coinbase, BitcoinJ) for Android and iOS and synchronize it with various API’s or create an application from the scratch.
Size of the development company
If you decide to get a highly customized wallet app, the estimated price will largely depend on the size of the company you are choosing. Anyway, cryptowallet development requires large investments and even hiring a small-sized company will cost you from $15,000-$20,000. The pricing depends on the features included. Also, the type of coins you want to use in your wallet app is a factor that influences the cost. Since it is not possible to calculate the exact cost of development, we will present the average prices of the basic features that are compulsory in your app:
Backend development from $10,000
Design from $7,000
Web/Desktop $7,000
Also, you can add numerous features to secure and vary your transactions:
Secured authentication & authorization, Windows/Linux/Mac wallet, iOS app, Android app, push notifications, QR code scanner, customer support, multiple cryptocurrency, optional password protection etc.
The development of a cryptocurrency wallet is an innovative tool that can bring your business to the next level. Evercode Lab developed a unique multi-currency crypto wallets (Atomic Wallet and Guarda), guaranteeing the fastest transactions, maximum security, and anonymity. Our company provides a wide range of services from consulting to a full-time development team as well as crypto asset security.

What Is Defi?

Cryptocurrency’s promise is to make money and payments universally accessible– to anyone, no matter where they are in the world.
The Decentralized Finance (DeFi) or Open Finance movement takes that promise a step further. Imagine a global, open alternative to every financial service you use today — savings, loans, trading, insurance and more — accessible to anyone in the world with a smartphone and internet connection.
This is now possible on smart contract blockchains, like Ethereum. “Smart contracts” are programs running on the blockchain that can execute automatically when certain conditions are met. These smart contracts enable developers to build far more sophisticated functionality than simply sending and receiving cryptocurrency. These programs are what we now call decentralized apps, or dapps.
You can think of a dapp as an app that is built on decentralized technology, rather than being built and controlled by a single, centralized entity or company. (Get used to this word, dapp, you’ll be seeing it a lot from here on out.)
While some of these concepts might sound futuristic–automated loans negotiated directly between two strangers in different parts of the world, without a bank in the middle– many of these dapps are already live today. There are DeFi dapps that allow you to create stablecoins (cryptocurrency whose value is pegged to the US dollar), lend out money and earn interest on your crypto, take out a loan, exchange one asset for another, go long or short assets, and implement automated, advanced investment strategies.

What differentiates these DeFi dapps from their traditional bank or Wall Street counterparts?

At their core, the operations of these businesses are not managed by an institution and its employees — instead the rules are written in code (or smart contract, as mentioned above). Once the smart contract is deployed to the blockchain, DeFi dapps can run themselves with little to no human intervention (although in practice developers often do maintain the dapps with upgrades or bug fixes).
The code is transparent on the blockchain for anyone to audit. This builds a different kind of trust with users, because anyone has the opportunity to understand the contract’s functionality or find bugs. All transaction activity is also public for anyone to view. While this may raise privacy questions, transactions are pseudonymous by default, i.e. not tied directly to your real-life identity.
Dapps are designed to be global from day one — Whether you’re in Texas or Tanzania, you have access to the same DeFi services and networks. Of course, local regulations may apply but, technically speaking, most DeFi apps are available to anyone with an internet connection.
Permissionless” to create, “permissionless” to participate — anyone can create DeFi apps, and anyone can use them. Unlike finance today, there are no gatekeepers or accounts with lengthy forms. Users interact directly with the smart contracts from their crypto wallets.
Flexible user experience — don’t like the interface to a certain dapp? No problem — you can use a third party interface, or build your own. Smart contracts are like an open API that anyone can build an app for.
Interoperable — new DeFi applications can be built or composed by combining other DeFi products like Lego pieces — e.g. stablecoins, decentralized exchanges, and prediction markets can be combined to form entirely new products.
DeFi is now one of the fastest growing sectors in crypto. Industry observers measure traction with a unique new metric — “ETH locked in DeFi”. At the time of writing, users have deposited over $600 million worth of crypto into these smart contracts.
Intrigued? Let’s take a closer look at just a few of the popular DeFi dapps out there that you can try today. You’ll need a cryptocurrency wallet with a built-in dapp browser (like Coinbase Wallet) to connect to these dapps. You can also use most of these dapps on desktop by selecting the Coinbase Wallet option and scanning a QR code.
It’s still early days for dapps, so DeFi users should do their research on new products and services. Like any computer code, smart contracts can be vulnerable to both unintended programming mistakes and malicious hacks.

Stablecoin and Decentralized Reserve Bank: MakerDAO

Maker is a stablecoin project where each stablecoin (called DAI) is pegged to the US Dollar and is backed by collateral in the form of crypto. Stablecoins offer the programmability of crypto without the downside of volatility that you see with “traditional” cryptocurrencies like Bitcoin or Ethereum.
You can try creating your own DAI stablecoin on the Maker Oasis dapp. Maker is more than just a stablecoin project, though–it aspires to be a decentralized reserve bank. People who hold a separate but related token, MKR, can vote on important decisions like the Stability Fee (similar to how the Federal Reserve’s Federal Open Market Committee votes on the Fed Funds rate).
Another stablecoin with a different architecture is USD Coin (USDC), where every USDC token is backed by one US dollar held in an audited bank account.
Borrow and Lend: Compound
Compound is a blockchain-based borrowing and lending dapp — you can lend your crypto out and earn interest on it. Or maybe you need some money to pay the rent or buy groceries, but your funds are tied up in your crypto investments? You can deposit your crypto to the Compound smart contract as collateral, and borrow against it. The Compound contract automatically matches borrowers and lenders, and adjusts interest rates dynamically based on supply and demand.
Other popular borrow/lend dapps are Dharma and dYdX. Aggregators like LoanScan track borrow/lend interest rates across the various dapps, so you can shop around for the best rates.
Automated Token Exchange: Uniswap
Uniswap is a cryptocurrency exchange run entirely on smart contracts, letting you trade popular tokens directly from your wallet. This is different from an exchange like Coinbase, which stores your crypto for you and holds your private keys for safekeeping. Uniswap uses an innovative mechanism known as Automated Market Making to automatically settle trades near the market price. In addition to trading, any user can become a liquidity provider, by supplying crypto to the Uniswap contract and earning a share of the exchange fees. This is called “pooling”.
Other popular Decentralized Exchange platforms (DEXes) include 0x, AirSwap, Bancor, Kyber, IDEX, Paradex and Radar Relay. All have slightly different architectures.
Prediction Markets: Augur
Augur is a decentralized prediction market protocol. With Augur, you can vote on the outcome of events, except you put ‘skin in the game’ by attaching a value to your vote. Prediction market platforms like Augur and Guesser are nascent, but offer a view into a future where users can make better predictions by tapping into the wisdom of the crowd.
Synthetic Assets: Synthetix
Synthetix is a platform that lets users create and exchange synthetic versions of assets like gold, silver, cryptocurrencies and traditional currencies like the Euro. The synthetic assets are backed by excess collateral locked into the Synthetix contracts.
No-loss savings games: PoolTogether
The composability of DeFi lends itself to infinite new possibilities. PoolTogether is a no-loss game where participants deposit the DAI stablecoin into a common pot. At the end of each month, one lucky participant wins all the interest earned, and everyone gets their initial deposits back.

So what’s next for DeFi?

Money and finance have been around in one form or the other since the dawn of human civilization. Crypto is just the latest digital avatar. In upcoming years, we might see every financial service that we use in today’s fiat system being rebuilt for the crypto ecosystem. We’ve already seen asset issuance and exchange, borrowing, lending, custody, and derivatives built for crypto. What’s next?
The first generation of DeFi dapps rely heavily on collateral as a safeguard. That is, you need to already own crypto and provide it as collateral in order to borrow more crypto. More traditional unsecured borrowing and lending will need to rely on an identity system, so that borrowers can build up credit and increase their borrowing power, much like today’s SSN and FICO scores. Unlike today’s identity and credit systems however, a decentralized identity will have to be both universal and privacy-preserving.
We’re also seeing innovation in the insurance space. Many of today’s DeFi loans are overcollateralized (meaning that loans seem inherently safe because of the generous cushion of assets held in reserve). But the black swan for DeFi is smart contract vulnerabilities. If a hacker finds and exploits a bug in the open source code for a dapp, millions of dollars could be drained in an instant. Teams like Nexus Mutual are building decentralized insurance that would make users whole in the event of smart contract hacks.
Another trend we’re seeing is better user experience. The first generation of dapps was built by blockchain enthusiasts for blockchain enthusiasts. These dapps did a great job of demonstrating exciting new DeFi possibilities, but the usability left something to be desired. The latest iterations of DeFi apps are prioritizing design and ease of use in order to take open finance to a wider audience.
In the future, we expect that crypto wallets will be the portal to all your digital asset activity, just like an internet browser today is your portal to the world’s news and information. Imagine a dashboard that shows you not just what assets you own, but how much you have locked up in different open finance protocols–loans, pools, and insurance contracts.
Across the DeFi ecosystem, we’re also seeing a move towards decentralizing governance and decision-making. Despite the word “decentralized” in DeFi, many projects today have master keys for the developers to shut down or disable dapps. This was done to allow for easy upgrades and provide an emergency shutoff valve in case of buggy code. However, as the code becomes more battle-tested, we expect developers will give up these backdoor switches. The DeFi community is experimenting with ways to allow stakeholders to vote on decisions, including through the use of blockchain-based Decentralized Autonomous Organizations (DAOs).
Something magical is happening in the open financial system — crypto is bringing money online, and we’re seeing a quantum leap in what’s possible when it comes to the functionality of money. It’s a rare opportunity to see an entirely new industry blossom from scratch. The DeFi space will at first play catch up with today’s financial services industry. But over time, it’s hard to even fathom what innovations will come about when the power to build financial services is democratized to anyone who can write code.

How to add https in btc-rpc-explorer?

Hi everyone, I installed btc-rpc-explorer on my Linux, it's working and whoever had the idea of ​​carrying out and maintaining this project is to be congratulated!
However, when accessing the address (localhost: 3002) there is no https that allows an encrypted and secure connection. Is there any way to do that? Remembering that I am totally about internet protocols, but if someone explains it right I will surely learn.
The other question I have is about browsing bitcoin addresses on btc-rpc-explorer, it is not possible to search for addresses, only TXs, when I click on an address it shows only basic information and QR code, but it does not show the transactions that happened on that Address
When I click on the address it says that I must configure an address API like an Electrum Server ... Does anyone who has managed to do this know to inform me if it is easy?

Introduction to The Quantum Resistant Ledger

Overview
Introduction
Quantum computers, which have at times been dismissed as a physical impossibility, have gone from the realm of "if" to the realm of "when" over the last decade.
QRL was early to recognize the threat quantum computers posed, not just to data security of the world, but blockchain as well. In response, we created a fully open source (MIT)[1], independently audited[2,3], blockchain platform[4,5], secure against even an attack from quantum computers[6].
With security as a foundation, we've developed a feature rich platform with things like notarization[7], multisig transactions[8], and an Ephemeral Messaging System[9]. This is all done with performance[10] in mind to handle volumes expected of any enterprise-grade blockchain. Future developments include Smart Contracts, and PoS.
QRL is backed by the research of individuals, organizations and institutions, with citations from several[11]. We are commited to the scientific philosophy to development with 3 open research grants[12].

Use LN to pay on-chain address - any serious gateway?

I am looking for a forwarder / converter from LN to on-chain Bitcoin address.
I only found https://lightningconductor.net/ but it is problematic: QR codes are broken on my Firefox, fees are deducted from the output amount instead of being added on top of the input amount, etc.
For the purpose of this question, I am fine with trusting the forwarder.
UPDATE
I reviewed options from your comments and here is my summary:
  1. https://boltz.exchange/ - recommended, worked fine in multiple tests, Tor Onion Service, claims being trustless (I did not verify the claim), the output amount is not smaller than advertised (so it seems okay for paying external on-chain invoices)
  2. https://fixedfloat.com/ - nice alternative, worked fine in my test, no onion but works with Tor Browser, trusted, nice UX, precise output amount with the "fixed fee" option (so okay for paying external on-chain invoices)
  3. https://ln.zone/ - nice alternative, worked in my test, no onion but works with Tor Browser, trusted, one must add a fixed fee to input amount to get target output amount (predictable but a bit inconvenient for paying external on-chain invoices)
Other services were either API-only, or don't support LN->BTC direction, or broken on Tor, or had other issues.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

⚡ Lightning FAQs ⚡

If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily,
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source

Bitcoin Stack Exchange Answer
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Stack Exchange Answer
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
No -- Source
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
Stack Exchange Answer
Can the Lightning Network work on any other cryptocurrency? How?
Stack Exchange Answer
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?

Why the Verge-Pornhub partnership didn't move the market, and why usability continues to stall adoption

I'll let somebody else point out that very few people pay for porn to begin with. Very optimistically let's say its 1:10 PH users. Within that group, there's going to be small pool that own bitcoin, and much much fewer people have the technical ability to understand how to use exchanges and wallets.
A raw crypto checkout option is not a product. One that is basically a credit card funnel through ProbilleCoinpayments is even less of a crypto checkout option (which is what they did). This is a glorified extra-long credit card checkout option in disguise, where you still have to create a username and tie it to an email address. No email, no checkout. Yeah.
Think about it. Let's say I'm your average college hornball and I want to get a PH subscription. Exit the Matrix and walk through the steps of a normal human being just trying to use this new bold Internet:
  1. Spend 3 days feverishly researching how to use a wallet
  2. Sign up for Coinbase where I likely can't use a credit card
  3. Pay my bank a crazy fee to transfer money, if I even can
  4. Wait literally days later to jerk off in the future
  5. Sign up for a Binance account or some other exchange
  6. Setup 2FA after completing an intro course in computer science
  7. Trade my coins to Verge
  8. Move Verge to Pornhub through their cryptic checkout option . (Probiller which then sends you to CoinPayments)
  9. No redirect into your account. Apparently wait for an email to confirm the transaction (seriously?)
Imagine trying to do all that from a smartphone. No way.
Yeah, not going to happen.
Consider this check-out flow instead:
1) Let's buy porn! Do you already own Verge (y/n)
Y) Here's our wallet address and a QR code, on standby to let you in (confirms it and you're in, here's your randomly generated usepass pair, to recover it here's a 12 word recovery phrase -- zero bullshit!)
N) First you'll need a wallet, let's install one. Mobile or Desktop? And the wallet uses an API to a fiat processor, instead of the madness they implemented.
It's not that hard, people.
I said it before and I said it again: the user experience is the product. Verge-Pornhub have no product. What they built is a tiny pinhole to crawl through, and that means nothing for adoption.
Adoption starts when using crypto requires no explanation.
Had Verge focused on usability instead of this incredibly expensive stunt there would be more volume and more integrations without having to throw crowdfunded money at a site to add them. It's not going last. There is no substitute or shortcut towards building a good user experience. You have to sit down with real people.
Instead, we have this awkward moment where early Verge investors feel misled, if not embarrassed, to forcefully have their portfolios thrown into the porn business.

Beware of Lab Bot Data Storage Hackers Scam - A Fake Lab Bet Hack Extortion

Beware of Lab Bot Data Storage Hackers Scam - A Fake Lab Bet Hack Extortion
If you have recently got the extortion emails or messages about "Lab Bot Email", "Data Storage Hackers", "Lab Bot Hack", "Lab Bet Hack" or "Lab Bot Hackers", then you no need to worry, they haven't hacked your anything, it's a just fake extortion sent by scammers to trick you into sending them money. Actually, extortion itself is a criminal activity but we don't know how to categorize those who send fake extortion. So, yes, definitely, Lab Bot Hack messages as shown in the examples below is a scam.

Examples of scam messages: Lab Bot Hackers or Data Storage Hackers:-

"Please do not ignore this message, as it refers to your account (your email address) and cloud storage.
We are a group of data storage hackers.
If you receive this message, we've already hack you.
We are software developers (Login And Backup or often called LAB Bot).
Frequently asked questions (FAQs)
Q: What Is the LAB Bot?
A: LAB is an automated application made by Bot using a special API request; the API can download all the data or files that are related to your cloud storage and send it to our server automatically via hacked email access.
Q: Definitely, you'll think this is impossible!
A: Smartphones, Apple, Windows, etc. All have cloud storage data. Like Google with Gdrive, Microsoft with OneDrive, Apple with iCloud, and all cloud storage directly connected to an email account.
D: Why should you care about LAB Bot?
A: Lab Bot is automatically configured and has a five day grace period. On the fifth day, Lab Bot will accomplish its final task.
i.e., share backup data downloaded to the darknet forum publicly or to e-mail correspondence, contacts, social network, co-worker. (You certainly didn't want everyone to see or know your private files (documents, nude photos, hot videos, or others).
Precisely what should you do?
To prevent all of this thing from happening, you need to send Bitcoin with the amount of 0.22034 Bitcoin - to my bitcoin wallet address. (if you didn't know this, search 'how to buy bitcoin' on Google.)
BTC address:
Scan the QR code with your phone to get the address.
So, to stop the LAB Bot process, it's only in one way; "make payments through Bitcoin in the amount of 0,22034 Bitcoin". You have five days to make a payment, and the time will start when this message opened; LAB Bot will know if you've already read the letter because it uses e-mail trackers."

Hello. I'm 21, without IT or informatics studies and here is my contribution for Bitcoin

For almost 2 months I started to work from passion to a bitcoin website. First, it was supposed to be a blog with advices, but reading some project's instructions on github, I started to search for more info and start a new website with handy tools for Bitcoin :).
Because I have a job in an offline environment, I only worked 2-3 hours on evening. Without experience I used a lot of copy-paste, learned more about bitcoin and API management.
Now, I'm very glad with my project, https://bitcotools.com :) - a full bitcoin converter - fee recomandation - verify signed message - transaction broadcast - check multiple balances - qr code generator
I'm sure that I will not stop here and I will continue to add more features and graphics on this site, despite the fact that I do not have necessary knowledge.
Main idea is that everybody that have a passion for Bitcoin should start doing something to help this big revolution; like a blog post, an original widget, a presentation, a share...anything that can help ;). Somebody would appreciate your work.
EDIT: Thank you for your constructive feedback. All modification you suggested are done. :)

Generating a Transaction Hash

I am wanting to be able to take paper wallets and transfer the Litecoin/Bitcoin/Dogecoin off of them into another wallet. I really don't want to download an app to my phone, scan QR codes, import that, transfer that, etc. I would love to be able to enter the private key into a offline website (like the websites that generates paper wallets) and API call or manually enter that into (https://live.blockcypher.com/ltc/pushtx/) and it will "sweep" the wallets.
But I cannot find any easy method of doing this that works for Litecoin, etc.. I am wanting to use the same method for newer people into cyrpto so I can give them paper wallets and not have to explain to them how to download four different wallets just to get their money.
I am looking for something like coinb.in, but for Litecoin.. chain.so claims to, but I dont see a place that does this for Litecoin, only Bitcoin.
Is there anything like this out there? I cant seem to find anything!

Hello there,
I'm a small investor that will hodl the $ETN that I bought even if it goes to 1 Satoshi (I really don't care). However, I'm seeing that ETN is missing a great opportunity to show what actually ETN could offers to the market and this is frustrating at this point. I am not talking because there is a nice bump in the market, but because it is like some months that I'm thinking about how ETN doesn't show its potential.

By my understating, I know these things (please, correct me if I am wrong):
-Electroneum sell a smartphone with an app that gives an airdrop based in the location (cloud mining).
-Etn has a central entity to register an account to open a web-wallet, however it is possible to get a paper wallet.
- It is possible to open different outlets for an account.
-Etn run in a decentralized block-chain.
-The instant payment is in the beta phase and it's full working, with the integration of the POS.

Now, ETN allow anyone to discover the cryptocurrency and get the mining experience with the cloud mining, and this is a big point since bitcoin is a digital gold and it's quite complicate for regular user to spend or buy it. However, my big question is... why there is no app out there that shows how easy is to use etn?

I mean, I am a Web/App Developer and a Graphic Designer and I could make a game implementing the instant payment to show how a person could buy or access some feature of my game using the etn. This concept, could be used in different cases to show how quick is possible to pay and get what the customer is paying.

Am I missing something here? is there any example of a real implementation in some games or some apps?

Some suggestions:

- Sell the "gift card" with tot ETN amount. This would allow you to sell directly the etn and get the money to support the company.
- Start investing in people who could develops games/app based on accepting ETN as payment.
- Allow the outlet to send specific ETN from specific wallet by generating QR CODE using the API. This would allow hundreds scenarios in the crypto world. (for example, a user beat a level, then the app generate a unique qr code that will allow the user to get 100 ETN...)

PS: Please, as a graphic designer change the twitter and website brand identity. The design looks like a childlike. I don't think no one cares about making money from cloud mining using a pop art design.
Thanks for your attention.
