bitcoin had more power than the top 500 supercomputers This is a nonsensical comparison. Sure, nothing compares to the aggregate of all Bitcoin miners in quickly computing the last 32 bits of the double-SHA256 hash of particularly structured 80-byte inputs. But at the same time, Bitcoin mining hardware can also literally not do anything else. It can't ...

It would never, ever happen. The increase in difficulty and the reduction in mining reward would mean that you would never, ever accumulate anywhere near 1 BTC with a mining speed that low. You would need to be more than a billion times faster. Mining is perfectly competitive. Trying to mine with hardware like that is like trying to win a race to build a ...

No, it would not. A node that uses BIP 157/158 is not a full node. It is not downloading every single block and making sure that all blocks and transactions are valid, thus it is not a full node. You can already run a full node without storing the entire blockchain. For a very long time now, Bitcoin Core has supported pruning where it discards old blocks ...

A Bitcoin mining ASIC: does not attempt to complete a single hash, rather fragments of two SHA256 compression rounds which is then compared to a target, the result is never returned can not accept arbitrary information that is not in the form of a partial SHA256 compression round So in terms of competitiveness, a CPU can actually complete a SHA256 hash, ...

ZCash uses Equihash algorithm for proof of work rather than SHA256, so if it uses ASICs, the hardware would definitely not be compatible.

the hash rate for bitcoin tripled from around 15 EH/s to 45 EH/s. Why is this the case? Well, at the simplest level, that means more hashing power is being used to secure the network. This could mean that a larger number of ASIC units are running, and/or that more efficient ASIC units are being created and used. A more efficient ASIC would perform more ...

2) Is such a fullnode phone helpful and positive impact on the overall btc network (what are the positive impacts?)? In addition to what @Andrew wrote, its worth noting that a user should want to run a full node for their own gain, not just ‘for the health of the network’. Certainly more full nodes creates a more robust network, but we don’t depend on user ...

1) >How can this phone act as a "FULL NODE" of BTC? Is this really true? You could throw away your full node on linux computer, and instead use the HTC phone? A smartphone is just a lower power computer that fits in your pocket. For a computer to be a full node, it just needs to run full node software. Phones can already do this, and it seems like HTC is ...

Bitcoin clients no longer use version 2 or version 1 in the block headers. Block version is now defined as per BIP-9, and miners use specific bits in the block version number to signal their support for specific soft-forks in the bitcoin protocol. The top 3 bits of the blocks must be 001, so the range of actually possible nVersion values is from 0x20000000 ...

No l, floating point operation are pointless, regardless of how fast they are or what precision they have. Also, BTC is mined using ASICs since 5 years ago or so, using a GPU is a waste of time and money.

What you have here are components for a rig. They are not "rigged" yet, ie, not connected, not structured to work yet. The main components for a mining rig such as you show are: PC motherboard (there seems to be one in the 3rd picture, the one with a large circular heatsink with fan & intel label) so this is in fact the core component of a 'Personal ...

Both Bitmain and Braiins have now released S9 firmware that enables overt AsicBoost.

The main hardware difference is, the hash board heat sinks are different heights! You cannot use all 3 S9i hash boards in a regular S9. The S9i heat sinks are 3mm smaller on the bigger heat sink side(silver) and the smaller brown heat sinks on the other side are 3mm taller. You can only fit 2 S9i hash boards in a S9 housing.
