I'm having trouble understanding what it is and how to use it. The project website seems to be filled with buzzwords but no actual usecase.

The name hints at a being a DEX, but that doesn't seem to be it. They talk about banking for everyone, but they don't have a coin. What exactly is it and how can one use it? Is it usable by laymen?

Maybe @[email protected] can answer or anybody else who understands it...

"The Oslo Freedom Forum, held annually by the Human Rights Foundation, has become a worldwide cornerstone for human rights activists. This year, the 16th edition of the forum was centered around the theme "Re-claim Democracy." It brought together activists, thinkers, and leaders to discuss the challenges of rising authoritarianism and how bitcoin can support activists fighting against oppressive regimes."

This exchange claims doing ~30% of Monero XMR trading volume following CoinGecko markets tab.

Monero is a good example because it's not that much speculated (more used as a currency), when looking kraken or tradeogre.

On an other side, nobody mentions Gate as a platform to buy Monero or as a liquidity provider for instant crypto exchanges.

"The Ethereum Foundation (Stiftung Ethereum) has never been contacted by any agency anywhere in the world in a way which requires that contact not to be disclosed. Stiftung Ethereum will publicly disclose any sort of inquiry from government agencies that falls outside the scope of regular business operations."

In Ethereum the gasLimit is 21000. The constant.

I haven't found anywhere the value of it for Polygon, though. How much is it? For a token as well as for MATIC itself.

I've found the number 57000 on an explorer in a real TX. Yet I haven't been able to find a confirmation for it elsewhere.

What I need is to specify a limit in my codebase for transfers of MATIC and tokens only. There won't be any calls to smart-contracts. What number should I put there?

Simple question, but I haven't been able to find any decent answer yet: Does anyone have a good guide for reducing fees when buying and selling coins for fiat?

I'm currently using Exodus wallet with my Trezor model T and have been having a rough time with it. If I download another wallet software and plug my trezor model T in will the same wallets come up if the wallet passwords are the same or is that not how that works?

If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.

What is Bitcoin Black Friday?

Black Friday is ~1 month before Christmas, and it's the busiest shopping day in the US. The first "Bitcoin Friday" (launched by Jon Holmquist) was Nov 9th, 2012 (at the time, one bitcoin was ~$11). The following year, the two ideas merged to become Bitcoin Black Friday.

This year, we're joining Bitcoin Black Friday by offering our products at a 10% discount if you pay with cryptocurrency.

Why should I use cryptocurrencies?

We've always accepted cryptocurrencies because:

1. They're more secure than pre-cryptocurrency payment methods
2. They're a more egalitarian system than pre-cryptocurrency finance
3. They're more environmentally friendly than pre-cryptocurrency financial systems
4. The fees are less than pre-cryptocurrency transactions
5. They allow for anonymous purchases online
6. Their transactions are censorship-resistant

Security

Before cryptocurrencies, making an online transaction was horrendously insecure and backwards.

"Conceptually, pull-based transactions are really not that different than giving three parties the password to your online banking service and trusting them to log in and take what they need. You have to trust the merchant, their IT supplier; the acquiring bank, their third-party processor; the card network; and your own card issuer---and everybody who works for them and has access to their systems. If a bad guy gets hold of your card details at any point in this process, they could drain your account.
The picture shows the scope of all the entities with access to your critical card information" source

Asymmetric cryptography has been available since the 1970s, but CNP (Card Not Present) transactions to this day still don't use public keys to sign transactions. Rather, you give your private keys (that is, your credit card number, expiry, etc) directly to the merchant and you authorize them to pull money out of your account (trusting that they take the right amount and not to loose those precious credentials).

Bitcoin flipped this around to actually make transactions secure. With bitcoin, you don't give others the keys to take money out of your account. Instead, transactions are push-based. You sign a transaction with your private keys, and those keys are shared with no-one.

Even today, pre-cryptocurrency transactions are abhorrently insecure. In the US or Europe, if someone knows your account number and bank, they can direct debit money out of your account. For the same reason, losses due to credit card theft is enormous. To quote Satoshi Nakamoto's criticism of pre-cryptocurrency transactions, "A certain percentage of fraud is accepted as unavoidable"

In fact, fraudulent transactions in the banking industry are so common that your bank will generally reimburse your account for any malicious transactions that you tell them about within 60-90 days. But if someone drains your account of all your money and you don't notice for 12 months? Too bad. All your money is gone.

In Bitcoin, transactions are push-based. source

Tokenization and 3DS are merely bandages on a fundamentally backwards, pull-based transaction model. But because bitcoin is push-based, it's magnitudes more secure.

Egalitarian

If you have a bank account, then you probably take a lot of things for granted. Like buying things online (with a credit card). Or getting cash when traveling abroad (from an ATM machine). Or taking out a loan so you can start a business.

Before crypto-currencies, it was very difficult to do these things unless you had a bank account. And in 2008 (the year with the first-ever bitcoin transaction), McKinsey & Company published a report concluding that half of the world's adult population is unbanked.

But with crypto-currencies, anyone with access to the internet and a computer or smart phone can use bitcoin to send and receive money online -- without needing to first obtain a bank account.

Environmentalism

The energy required to facilitate transactions in decentralized, blockchain-based cryptocurrencies like bitcoin is minuscule by comparison. And, most importantly, the amount of energy used to solve the proof-of-work problem does not grow as the number of transactions-per-second grows.

Traditional financial institutions require an enormous amount of overhead to facilitate transactions in their centralized networks. Unlike bitcoin, which was designed specifically to eliminate the unnecessary overhead created by a trusted third party, pre-cryptocurrency transactions required humans to verify transactions. These humans require office buildings. These office buildings require energy to build and maintain. And, most importantly, as the number of transactions-per-second grows on their network, the number of humans and office space also grows.

Bitcoin versus other industries

yearly energy use, in TWh source |

This fact is often misunderstood because there's a lot of misinformation on the Internet that makes a few disingenuous modifications to the facts:

1. They calculate the energy usage of the computers processing transactions only, maliciously omitting calculating the energy usage of the entire industry's infrastructure (eg energy used by office buildings)
2. They calculate the energy usage per transaction, maliciously omitting the fact that the amount of energy expended by bitcoin miners is automatically adjusted by the proof-of-work algorithm (so energy usage does not increase as the network scales-up)
3. They offer statistics about "energy usage" without mentioning the energy sources. It matters if the energy source is coal/nuclear/natural-gas or solar/wind/hydroelectric

"...estimates for what percentage of Bitcoin mining uses renewable energy vary widely. In December 2019, one report suggested that 73% of Bitcoin's energy consumption was carbon neutral, largely due to the abundance of hydro power in major mining hubs such as Southwest China and Scandinavia. On the other hand, the CCAF estimated in September 2020 that the figure is closer to 39%. But even if the lower number is correct, that's still almost twice as much [renewable energy sources] as the U.S. grid"

The facts are that the energy usage of bitcoin is magnitudes less than the energy used by pre-cryptocurrency financial intuitions, that energy usage does not increase as the number of transactions processed by the network increases, and that mining bitcoin is often done with renewable energy.

Low Fees

The introduction to the Bitcoin White Paper (2008) clearly states that Bitcoin was created to reduce costs by using a distributed ledger (the blockchain) to eliminate the need for a trusted third party.

"Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model.
Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs...
These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.
What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions."
source: Bitcoin Whitepaper	Satoshi Nakamoto

At the time of writing, the average transaction fee for a bitcoin transaction is $0.06. And unlike pre-cryptocurrency transactions, you can increase or decrease the fee that you pay to increase or decrease the time it takes for the transaction to complete (at $0.06, it will get added to the blockchain in ~1 hour).

By comparison, the way to send funds internationally through the Internet via pre-cryptocurrency banks is via an international wire transfer. Fees very per bank, but they typically charge $15-$85 per transaction. And unlike bitcoin, wire transfers won't make move on nights and weekends, so they can take 1-7 days to complete.

Also, with bitcoin, that $0.06 transaction fee only applies when you're sending money. Many banks will also charge a fee for an incoming wire transfer. In bitcoin, there is no transaction fee to receive money.

Anonymity

Though early cryptocurrencies like Bitcoin don't ensure anonymity like newer privacy coins, ZCash and Monero were designed specifically to provide private transactions.

This allows our customers to purchase from us anonymously, which can be extremely important for activists and journalists whose lives are threatened by their adversaries.

WikiLeaks started accepting donations in Bitcoin 7 months after PayPal froze their account

We accept both ZCash and Monero. If you'd like us to accept another privacy coin, please contact us :)

Censorship-Resistant

Cryptocurrencies like bitcoin are peer-to-peer and permissionless. Transactions exchanging bitcoins occur directly between two parties. There is no middle-man that has the power to block, freeze, or reverse transactions. Before blockchains were used to maintain a public ledger and enable peer-to-peer transactions, we were dependent on big financial institutions to move money on our behalf through the internet. That antiquated system allowed them to censor transactions, such as donations made to media outlets reporting war crimes and donations to protest movements.

"For me, that is one of the coolest things about bitcoin...
People can potentially use it donate more anonymously to dissident groups and causes in a world where mass government surveillance threatens freedom of expression and certainly harms activists' ability to fundraise for their work, when people are afraid they could be targeted by a government for donating to a worthy cause."

After PayPal froze WikiLeaks's donation account in 2010, WikiLeaks started accepting bicoin in 2011. From Occupy Wall Street to Ukraine, defenders of democracy have utilized permissionless cryptocurrencies to accept international donations without the risk of transactions made through financial institutions.

I want to be able to achive this:

• a private key or its substitute (P) of a user wallet is stored on a server

• there're 100s of user wallets there, so there're 100s of (P) too

• let's say, it's ETH, SOL or any other major network

• server isn't a safe environment, as it's known

• there's also a main, admin wallet (M), in cold, local storage

• (P) must only be used to send outbound TXs to (M). Not anywhere else

This can't be achived with a normal private key, right? But how, if at all, it can be archived? Multisignature wallets?

The goal is automate withdrawals from the user wallets on a server, to make the process safer.

I don't consider any third-party solutions.

Community coming back to life with the death of MOONS?

Hello, did you know about signum network? I've been researching it for some time and it seems good, nothing wrong about it besides low popularity. It uses proof of capacity (where mining is reading special files from disk instead of using cpu or gpu). It has low transaction fees and overall looks like a good project. Do you know any particular reason why it's not more popular?

Hey all,

I've been curious about purchasing Monero lately, but I'm not a fan of dealing with KYC requirements or those annoying minimum purchase amounts. I'm sure some of you have already found some great platforms that offer a more hassle-free experience.

Could you please share your recommendations for where to buy Monero without any KYC hoops to jump through or pesky minimum purchase restrictions? Your insights would be greatly appreciated! Thanks in advance for your help!

From my experience, it seems that any service that offers cryptocurrency payments seems to always set them up as a one time purchase that you manually must renew periodically. Is there any standard that exists, or is in the works that supports recurring payments to a service directly from a wallet?
