Google Lets Slip That It's Exploring Possible Bitcoin Integration

Google Lets Slip That It's Exploring Possible Bitcoin Integration

Since Overstock.com began accepting Bitcoin payments earlier this month, the cryptocurrency community has been buzzing with speculation about which tech company will integrate Bitcoin next. So Jarar Malik decided to ask.

“After the whole Overstock thing, I said ‘f–k it,’” says Malik, a Bitcoin early adopter, online marketing manager and musician with a following in Pakistan. “‘Let me email the head guys at a bunch of tech companies and see what they say.’”

He started with Jeff Bezos and Tim Cook, asking if Apple Apple or Amazon had any plans for the cryptocurrency. No response. Then he tried the Google Google triumvirate Larry Page, Sergey Brin and Eric Schmidt.

When they also ignored him, he moved down a rung to Google’s Senior Vice President Vic Gundotra. And to his surprise, Gundotra wrote him back, forwarding Malik’s query to another Google staffer and starting a series of email exchanges that eventually led to one Googler telling Malik that the company is indeed pondering how it can make use of the world’s first form of decentralized digital cash.

“We are working in the payments team to figure out how to incorporate bitcoin into our plans,” wrote Google Senior VP of Ads and Commerce Sridhar Ramaswamy at one point in the email exchange that Malik forwarded to me. He promised to get back in touch “when we are a little more sure.”

When Malik posted Ramaswamy’s response to the Bitcoin forum on Reddit and immediately got an positive response from the site’s bitcoiners, Google Wallet exec Ariel Bardin followed up by asking Malik to serve as a moderator on a Google survey posing the question “What would I want to do with Bitcoin?”

I reached out to Google, and the company responded in a very different tone, but didn’t deny that the comments Malik posted to Reddit were real. “As we continue to work on Google Wallet, we’re grateful for a very wide range of suggestions,” a spokesperson writes. ”While we’re keen to actively engage with Wallet users to help inform and shape the product, there’s no change to our position: we have no current plans regarding Bitcoin.”

Malik isn’t deterred. “They’re not dismissing it,” he says. “Maybe this will force their hand.”

Although it hasn’t adopted Bitcoin into any of its products, Google has been more Bitcoin-friendly than most other major tech firms. While Apple hasn’t allowed a single Bitcoin client into its iOS app store, dozens of Bitcoin wallets are available for Android. And in 2011, Eric Schmidt said at the Mobile World Congress that the company’s co-founders once considered introducing a Bitcoin-like virtual currency called Google Bucks, which he discouraged for regulatory reasons.

But some sort of Bitcoin integration could offer a boost to Google in its digital payments competition with Paypal. And Overstock.com illlustrated the buzz that Bitcoin adoption can generate earlier this month when it received $130,000 worth of Bitcoin sales in its first day accepting the currency, mostly from new customers.

Redditors certainly seemed wild about the idea. “I would love for google to make it possible to pay with bitcoin on most shops I come across,” wrote a user named Sturmhardt. “This is HUGE guys. I’ll move over to Google+ if this turns out to be true… ;-)” wrote a user named maxilllian.

As for Malik himself, he’s holding out hope that Google will make Bitcoin as ubiquitous and easy to use as Gmail. “Google is integrated in every part of our lives,” he says. “I’d like to see them let us send payments back and forth the same way we use email…to incorporate Bitcoin into our daily DNA.”

GrowthCoin (GRW) Crypto Currency



GrowthCoin (GRW) – a fork of Diamond, with several algorithms fixed and improved. It is decendent of Novacoin/PPCoin with Pow/PoS. It combines the great features from Luckycoin (random blocks) and Florincoin (transaction message).

Proof of stake coin is more resilient to 51% attack. Since 51% hashpower is not enough to execute a 51% attack. The attackers must also have at least 51% stake.

GrowthCoin provides monthly interest rate of 5.95%, for stakes that are held during that period of time. This equivalent to an annual interest of 100%. PoS blocks will be generated if the stake are held for more than 5 days. There is a hard limit of 2 billion coins.

PPCoin (Peer Coin) - Crypto Currency





PPC Specifications:

  • Blocks every 10 min
  • Coin supply* non-deterministic coins will be available
  • Difficulty adjustment each block
  • Hashing algorithm SHA-256
  • Reward varies on difficulty coins per block
Peer Coin, abbreviated PPC is a cryptocurrency which is forked from bitcoin. PPCoin aims to achieve high energy-efficiency while keeping as much as the official Bitcoin properties as possible.

PPCoin works with Stake/Proof-of-Stake, this is a term referring to the use of the currency itself to achieve certain goals.

PPCoin uses proof-of-stake to provide minting and transaction processing of place of proof-of-work. Unlike Bitcoin ppcoin does not require the use of energy to sustain the network. Proof-of-work currently remains the most practical way of providing initial minting of a cryptocurrency so it was decided to keep it as part of the hybrid design.

Untill v0.2, central checkpointing was a critical part of the protocol. The main purpose of this is to defend the network during the growth period and to ensure a smooth upgrade path if any critical vulnerabilities are found. Central checkpointing will slowly be weakened and should eventually removed from the coin.

Unlike Bitcoin there is no hard cap on the amount of coins that will be created. Bitcoin is limited to 21 million coins where PPCoin only has a hard cap of 2 billion coin in the code. There is no intention to limit the amount of coins that can be generated.

“There is a 2-billion coin max value in the source code, however that is only used for consistency checking and is not meant to be part of the minting design.”

Pennies (CENT) Coin - Crypto Currency



Introducing indivisible cryptocurrency- Pennies (CENT) Coin

Pennies [CENT] are a unique new cryptographic coin without decimal places. Every easy to mint coin is a single unit and is designed with Proof of Stake savings in mind. Pennies are based on scrypt-jane and set to retarget at long intervals to allow for easy CPU-based mining.

Specifications:

No decimals, no micro units, each penny is 1 coin.
1 CENT per block, 1,000,000,000 (this is 1billion, not 1 trillion) total cents via PoW.
Scrypt Jane (YAC) based, so mine via "Command Line Banking" and "setgenerate = true"
Progressive diff adjusment, targeted N factor retargeting at 1 week.

Quark (QRK) - Crypto Currency



Quark is a crypto-currency that allows online coin transactions. Quark uses nine rounds of secure hashing from six different algorithms to encode Quark transactions securely.

Specifications:

Super secure hashing: 9 rounds of hashing from 6 hashing functions (blake, bmw, groestl, jh, keccak, skein). 3 rounds apply a random hashing function.
* CPU mining
* Quick block generation: 30 seconds
* 2048 QRK per block (halving every 60480 blocks ~ 3 weeks)
* Block reward will never drop below 1 QRK
* Total of 247 million QRK will be mined in ~ 6 months, after that ~ 1 million QRK p.a. (~ 0.5% p.a inflation)
* Difficulty retargets every 20 blocks (maximum 10% up or 50% down)
