News articles that do not contain the word "Bitcoin" are usually off-topic. This subreddit is not about general financial news. Submissions that are mostly about some other cryptocurrency belong elsewhere. Promotion of client software which attempts to alter the Bitcoin protocol without overwhelming consensus is not permitted.
No referral links in submissions. No compilations of free Bitcoin sites. Trades should usually not be advertised here. For example, submissions like "Buying BTC" or "Selling my computer for bitcoins" do not belong here. New merchants are welcome to announce their services for Bitcoin, but after those have been announced they are no longer news and should not be re-posted. Aside from new merchant announcements, those interested in advertising to our audience should consider Reddit's self-serve advertising system.

Personal computers were the result of continuous innovation and change in which part of the developments remained proprietary such as chip-making technology , and part was fully exposed to the light of day in academic research and shipping products. The Internet grew as a result of well-documented government funding and with the initial participation of many thousands of people in academia, government, and private industry working together.
Much of this was public, and I could list off hundreds of people involved in the creation of the Internet, and the popularization of the Web—including Andreessen! Andreessen wants to paint parallels to show how Bitcoin has a fundamentally similar origin story, when there is little in common. By trying to normalize Bitcoin against previous technologies—PCs being primarily hardware with a significant software component and the Internet primarily data with a significant hardware component—he wants a general audience to accept that an entirely philosophical and intangible new thing is the same as these familiar old things.
I agree with Andreessen that Bitcoin is the first practical, large-scale mechanism to deal with the problem of decentralizing trust—no parties need know each other nor trust each other for transactions to complete successfully, verifiably, and irrevocably.
Bitcoin has a remarkable set of interlocking mechanisms that make it exceedingly hard for any individual or group to accumulate enough power to distort the public block chain, a sequence in which one set of transactions builds upon the next. If such distortion took place, it would become known, and various scenarios have been painted about what kind of response would occur. Some suggest Bitcoin would collapse, and thus that no party would engage in attempting it, however impractical it would be to achieve.
I also agree completely with Andreessen that Bitcoin can be used for an enormous number of non-currency related purposes in which permanent, irreversible proofs of transactions are required. Further, these transactions can be proven to have been created by a party who possesses a private key; no other party can create such a proof. One of the fundamental current software architects of Bitcoin, Mike Hearn, explained to me how such transactions could be used to validate identities for discussion forums and for passports.
As a payment system, he asserts Bitcoin has enormous advantages over current credit-card and bank-processing networks. That contains a bunch of problematic statements. Without getting into the weeds, many Bitcoin transactions can be carried out without fees or very low fees, but transactions are only committed into the global block chain when miners accept those transactions: The minimum rate to pay, when a fee is paid, is based on the size of the transaction in bytes, and starts at 0.
One can pay more, however. Transactions with higher fees attached are committed more quickly. As the rate of transactions has increased, the fee has seemingly become more important, as no-fee and low-fee transactions can linger for longer periods without being built into a block and made permanent and thus useful for consummating a deal. The team has no specific power; it has to convince a supermajority of participants in the Bitcoin ecosystem to adopt software updates.
Andreessen masks several upcoming problems with his seemingly straightforward statement:. Andreessen then moves into advantages related to fraud:. But that is only true within the Bitcoin system.
As far as can be determined, transactions are irreversible after a short period of time and cannot be counterfeited. Chargebacks occur in the credit-card processing world, as do stopped checks, because of a dispute between a buyer and seller.
Credit-card companies and banks mediate in disputes as a backstop to keep buyers happy and because of oceans of government regulations. On the other side, sellers by percentage of sales volume tend to be multi-billion-dollar companies, who otherwise have a lot of leverage against consumers and most other businesses. When Andreessen says there are no chargebacks this is the point of view of a merchant or seller who deals with fraud. This will move chargebacks from intermediary mediated settlements to small-claims court and higher civil courts.
This can, of course, save many tens or hundreds of billions of dollars a year globally and translate to more efficiency in commerce. Because Bitcoin is like untraceable cash, the process for solving a dispute would likely follow the same rules as for cash.
It also glosses over theft. Because Bitcoin relies entirely on the private retention of secrets private keys that prove ownership of given Bitcoins , a stolen Bitcoin is only traceable within the system to a certain extent, and thefts of millions and tens of millions of dollars have already occurred. Because committed transactions are irreversible, stolen Bitcoins are valuable and nearly laundered. The discussion of fees and fraud thus also excludes the overhead to businesses.
Companies will have to deal with fraud under the laws of the government under which they operate. We already have laws in America and most countries about receiving counterfeit currency it is valueless to the recipient when discovered and about fraudulent transactions: This is partly how the Madoff trustee has reclaimed lost billions from those who received payouts. The issues for PCs and the Internet were about utility, not about whether or not they actually existed and had value.
You could buy a PC; you could get an Internet connection. The cost and complexity of both started out so high, that early adoption was low, but the curve of acceleration for uptake was extremely high. With Bitcoin, we already have hard cash and credit cards that can be used for digital transactions, and we can transfer money as bits.
Bitcoin is a replacement or supplement for an existing creaky and somewhat broken system that nonetheless works. Is it a currency or a payment system? However, greater adoption could switch the verity of this statement and allow low-fee but some fee Bitcoin exchanges that take place in short periods of time.
Much of his argument, including instant transactions at Target your Bitcoin account is instantly filled if needed; Target instantly exchanges Bitcoins back to dollars , relies on such a future.
On another front, Andreessen overstates how readily trackable Bitcoins are when discussing theft and illegal activities:. This is only the case because of the current implementation.
