Funding Bitcoin development seems to have always been problematic.

While the Bitcoin industry collectively has raised more than a billion dollars worth of investment over the past years, development of the Free and Open Source Software the industry largely relies on has always had trouble gathering sufficient funds and manpower for development. Several arrangements to raise funds have been tried over the years – but with varying degrees of success and longevity.

Bitcoin Core, considered by many to be Bitcoin's “reference client,” therefore, announced a “Sponsorship Programme” earlier this week. As the latest effort to raise funds, this program is intended to be an easy access-point for companies and other Bitcoin industry players to support Bitcoin Core developers and projects. Companies that decide to take part in the sponsorship program will join a, so-far, short list of entities that do already help fund Bitcoin Core development.

All older clients are compatible with this change. Users and merchants should not be impacted. Miners are strongly recommended to upgrade to version 2 blocks. Once 95% of the miners have upgraded to version 2, the remainder will be orphaned if they fail to upgrade.

like there is ethereum blockchain and bitcoin one. or not?

1.Currency issuance: Bitcoin creates 12.5 new bitcoins every 10min (or 75/hr) while Ethereum creates 3 new ether every 15 seconds (or 720/hr).
2.Currency cap: Bitcoin is limited to 21 million bitcoins, of which 17m have been created so far. Ethereum has no hard cap currently, but there are plans to reduce or stop issuance in a year or two. There are currently roughly 100m ethers.
3.Bitcoin creates a new block every 10 minutes (on average). Ethereum creates a new block every 15 seconds.
4.While bitcoin has a scripting language built in, it’s very limited in functionality with only a few dozen operations. Ethereum has a full general-purpose language integrated (known in computer-speak as Turing-complete). Programs written in this built in language are known as “smart contracts”.
5.Ethereum assigns a cost, known as gas, to every operation or use of storage on the blockchain. Bitcoin transaction costs are based simply on their size.
6.Each block in bitcoin is limited to 1MB in size (or 8BM in the case of Bitcoin Cash). In Ethereum, blocks are capped by the gas-limit, the total overhead of all the operations in the block. In practice bitcoin can process 4 transactions per second, Ethereum roughly 15.
7.Ethereum smart contract code lives at its own address on the blockchain as opposed to being within a transaction as in the case of Bitcoin. Therefore Ethereum has two account types, one to hold user funds, the second to hold computer code (which can also hold funds).
8.Ethereum includes blocks that are valid but were outpaced by another newly accepted block. These almost-accepted blocks are known as “uncles” and their incorporation provides added security to the chain and allows Ethereum to have shorter block times.
9.Bitcoin’s hashing algorithm (SHA-256) can be performed efficiently with special purpose hardware, known as ASICs (application-specific integrated circuit). The Ethereum hashing algorithm (KECCAK-256) is memory intensive so it’s far more difficult to build an economical special-purpose chip for. This allows for Ethereum to have greater mining decentralization.
10.Ethereum has plans to move away from mining altogether by changing the consensus algorithm from Proof-of-Work (PoW) to Proof-of-Stake (PoS). PoS creates blocks based on the token holdings of the nodes rather than computational power. In addition, Ethereum plans to tackle scalability by implementing “sharding”. Sharding breaks up the blockchain into many many interconnected sub-blockchains. Bitcoin currently has no such plans.

can u give me some trustable resources to learn it?

At worst, this firmware backdoor allows Bitmain to shut off a large section of the global hashrate (estimated to be at up to 70% of all mining equipment). It can also be used to directly target specific machines or customers. Standard inbound firewall rules will not protect against this because the Antminer makes outbound connections.

Even without Bitmain being malicious, the API is unauthenticated and would allow any MITM, DNS or domain hijack to shutdown Antminers globally. Additionally the domain in question DNS is hosted by Cloudflare making it trivially subjected to government orders and state control.

Well, bye bitmain. I was going to try to buy from you, now I'll switch to other companies...

According to the Bitmain pre-IPO investor deck, they sold most of their #Bitcoin for #Bcash. At $900/BCH, they've bled half a billion in the last 3 months. If Bitcoin Core devs didn't disclose the Bcash vulnerability, it could've wiped a billion dollars off their balance sheets.

Hi.

I am making a microwallet, and I am looking for a API or something that I can use in PHP to generate address and send transactions.

Thank you very much.


( Also if you know one for altcoins, please tell me )

Hi,

I wanted to pay for something on the internet, but I didn't send enough bitcoin to get it, as the website I'm making the transfer from only let me put 6 decimals.
How can I fix the issue?

Thanks in advance.

I have few concerns regarding this, say BTC does Hit 100k suddenly (like it did when it jumped to 19k about a year ago) at some point, will Any Exchange actually accept buying my ONE (1 BTC) and give me Cash ?.....

Which Trusted International Exchanges should I deal with to sell my BTC in exchange for Fiat ??...

I am from Dubai, we have here a website called Bitoasis, but am hesitant, I have a feeling that many exchanges will refuse buying my BTC for real cash WHEN BTC hits huge numbers 30-100k $...

plz correct me if am wrong...

I have just heard the word faucet.
And the question is does it really worth it?

Thank you for giving a free guide for those who want's to start their own faucet site. You are a great person dude. I'll give it a try to make my own faucet site, by the way what is the best capital $ to start my own faucet?

hello, thank you for sharing these guides with us. I never considered running my own faucet site. But thanks to your post, I am going to give it a try. very cool idea

I am going through your guide for launching premium faucet site and have few questions, if I may:

what is the difference between paid ($100) and free fauce scripts?
does it make a difference if my site has free or paid domain? you mention both options


thank you for sharing this with us

i think it is more secure and reliable trading platform. it will make you transaction easily and ensure transparency. it is more potential and committed to perform better service.

it is more potential and committed to perform better service.

The weirdest part of this to me is that the website's called AIMiner, but this has nothing to do with mining at all- might just be a repurposed domain name.

Lately, I have been hearing about these things called ICOs.

Can someone explain what they are? Curious to learn, thanks!  

Nice idea will definitely try it out,

Some question of concern,
1- Can i profit on shorting ?
2- Will this be an ongoing service ?

Thank You.

Do you know? all mods are also human being and will die. They are not GOD so why so much ego and giving sad so easily even not giving a second chance to others who are trying to earn some bucks by using this group for their life because no one can be reach by this earning?

Love all and help all as best as possible that will help you forever for a peacful life. Money is not everything in the life.

If one person feels sad or cries for you then you are not good human being and that KARMA will follow you.

Money is not everything in the life.

You're getting this error because bitcoind isn't running. Once it is, it will create an authentication cookie, and bitcoin-cli will be able to connect.

To start bitcoind from cmd prompt, type:
Press enter, then type:
And press enter.

I would stay away from Blockchain wallet. I have been using it few months back and I stopped after my balance on this wallet reached 10k$. I was not anymore able to send, but I could still receive. I tried many different browsers but it was exactly the same effect. I can't say if there was any technical issue or whatever, but very very strange that it happened once my balance there was over 10k.
I think as hot wallet to do daily small transactions, its something we can use.
And by the way, check their ToS, you will see that Blockchain is not anymore a place to trust.

If you want to use the wallet with the big security. Come on all the wallets are same to use it you missed to keep the fund safe with all the private key secured wallets. I do not know wallets completely secured even you do the mistake.

Common mistakes like private key sharing and phishing site access is the biggest problems to get scammed. Here are suggestion. Electrum, Multibit. Blockchain and Exodus.

I think it is so to some extent but still I may not buy that coin because my goal is to make profit not hold good coins.

Guys is that posible token price become 0 ?
And market price depend on demand and supply right.  so let say in market a :  coin x price = 1$ with active volume  in market b : coin x price = 1$ with almost passive volume.
how the price beetween that exchange almost same?

Guys is that posible token price become 0 ?

Hi.  The private key has 52 xters.  Thanks.

hardware wallets do still have a risk . what if you drop them ? that may cause a shock or corruption to your data 's . you can also get a virus and other threats if you connect your hardware wallet online whenever you transafer files or data . so overall , I don't think that there is a secure wallet . not only on cryptos but also to other types or forms of storage (e.g banks , piggy banks , personal wallets ,etc ) . best way to do to minimize the risk of loosing it all , is to divide or diversify your cash/cryptos to different kind of wallets or much better if you can withdraw some of them and keep your own money with you .

Your private keys are safe, that's what the device is for (protecting you against malwares).

What the Nano S will not protect you against:

Malwares that change the addresses displayed in your browser: let's say you are buying stuff on the Web, the webshop displays address "1abcd" and in a split second, the malware changes it to "1zzzz". The idea is that you will then copy/paste the fake address and send funds to it

Validating transactions without double-checking: when signing a transaction, the Nano S will always ask you to double-check the receipient address; if that address has been modified on-the-fly and you don't double-check if what's displayed on the device's screen is really the address you are trying to send funds to, you will lose money

Note that the first case is more likely to happen than the second one right now (there are no known malwares that target transaction building right now) but both of them are valid scenarios and may become more frequent in the near future.

Hi, am trying to convert bitcoins to Doge coins in coinpot, but 3-4 days ago this message showed up and coinpot doesn't let me withdraw all the amount.  

For fraud prevention reasons all offer/surveys earnings are put on hold for up to 10 days
before they can be withdrawn.
