I want to test raw transaction features. mhj9NdGREwiGsCNXfGatzu3RboyNiah68Z Testnet is useful, thanks.

I am mining at a speed of 3.15573555, Gigital Ocean's control panel says it uses less than 40% of the CPU. Launch another client program in the droplet. You should be able to double your speed. How? Could you explain me, please?

I have signed up with Digital Ocean. Piyxv6aY45psg3qttGXf2mSdQdXtQiG1vk Thanks in advance.

I think that Momentum also has Time-Memory-Trade-Off (TMTO). There are some birthday attack algorithms, one particular example is Floyd's cycle finding algorithm, which can be used to find hash collisions using memory of O(1). Fortunately, because the nonce space is limited to 2^26 bits, and the collision difficulty is 50 bits, the "memoryless" attacker is forced to try about 16 million (2^(50-26)) times harder to find one 50-bit-collision than he was given full nonce size of 50 bits.

What's the point of this coin? It is neither asic-resistant nor gpu-resistant. Is the strength of this coin an efficient cryptographic hashing function? I wonder if an inflational fork will succeed in the future.

Quote from: pedrog on September 03, 2013, 01:11:13 PM It's a little more complicated than that, the consensus of the network doesn't rests only on hashrate power, ever full node is a vote, so it may be impossible to control the protocol like that. Ledger consensus of Bitcoin relies on voting based on hashing power (in my understanding...). So it is a problem if large portion of hashing power is controlled by a few companies, I think.

Quote from: pedrog on September 02, 2013, 05:16:28 PM If that happens, bitcoin fails! Yes, I think that way, too. Wondering saving bitcoin is feasible or not. But I also think that at the stage of extreme concentration, we may have to embrace it. And Bitcoin will be like just one of the money services operated by ordinary corporations (still all transactions might be visible to anyone, though).

I happened to see this post. This will be my first try of NVC. Thank you! 4LVSsof2jmJDB1zRF45uzCKAAc1kYU6dtM

I wonder if that will happen in the near future. Concentration of mining power eliminates one unique characteristic of bitcoin (distributed network). It is inevitable because concentration gives an advantage of cost-effective mining capability. Ultimately, the result will be extremely big mining data centers of only 3 or 4 locations. At that time, does the price of bitcoins rely on historical or story-telling value?
