An Analysis of the First 100000 Blocks

After a profitable launch, Frontier handed it is 100000th block earlier this week. Listed below are some fascinating stats from these first blocks.

The primary 50 block instances (in seconds):

Proper after genesis, it took 29 seconds for the second block to look, then 31 and 29 seconds for the subsequent couple of blocks. Not too stunning as the miners scrambled with their setups as the last genesis block turned identified.

After these first blocks, we see the block time drop considerably at the onslaught of bigger miners, flooring at 1 second that’s the restrict enforced by the consensus protocol.

Let’s now take a look at the common block time (each two hundredth block from genesis to dam 10000):


We will see the hashing energy actually attacking the community after the first few hundred blocks, with block instances at 1-2 seconds as the problem adjustment algorithm is catching up. This algorithm both will increase or decreases the problem by diff/2048 every block, relying on the block time.

After a couple of thousand blocks, we see the problem going up sufficient for block instances to get into the 4-5 second vary. After 9k blocks, we’re beginning to strategy the goal time of 15 seconds.

Whereas one can by no means know for certain whether or not a single miner makes use of a number of coinbase addresses, assuming they use a single one, we now have a fairly even distribution of hash energy over the first 100k blocks. 0xe6a7a1d47ff21b6321162aea7c6cb457d5476bca with 11% of hashing energy is ethpool, the first mining pool for Ethereum. Subsequent we now have two giant miners with round 8%. After these three the distribution is sort of even, with most miners having lower than 1% of whole hashing energy.

Nevertheless, issues develop quickly in the Ethereum world and if we take a look at the final 15k blocks we see:

0x580992b51e3925e23280efb93d3047c82f17e038 327  2.2%
0xbb7b8287f3f0a933474a79eae42cbca977791171 496  3.3%
0xf927a40c8b7f6e07c5af7fa2155b4864a4112b13 612  4.1%
0x790b8a3ce86e707ed0ed32bf89b3269692a23cc1 674  4.5%
0xe6a7a1d47ff21b6321162aea7c6cb457d5476bca 5775 38.5%

Right here it is clear ethpool is at present having virtually 40% of the hashing energy, and the 2nd and third greatest miners are all the way down to 4%

Blocks in a row

One other fascinating stat is to take a look at steady units of blocks from the identical miner. This can provide some perception into how hashing energy and latency is coming into play for bigger miners.

Early after launch, most blocks in a row we noticed was 6, for instance blocks 1578, 1579, 1580, 1581, 1582 and 1583 mined by 0x9dfc0377058b7b9eb277421769b56df1395705f0.

0xbb7b8287f3f0a933474a79eae42cbca977791171 additionally mined 6 blocks a couple of instances, for instance blocks 656, 657, 658, 659, 660 and 661.

This miner additionally mined 5, 4, 3 and a couple of blocks in a row on a quantity of events, not too stunning with 21% of the whole hashing energy at the time.

This occurred very early after launch when problem was quickly growing and plenty of miners had not but joined the community. As hashing energy evened out after block 5000 we didn’t see greater than 4 blocks in a row for a while.

Nevertheless, not too long ago the most blocks in a row is 10, for instance blocks 103049, 103050, 103051, 103052, 103053, 103054, 103055, 103056, 103057, 103058 by ethpool. Excluding ethpool, no miner has had greater than 6 blocks in a row.

Keep tuned for extra statistics from the Frontier community as we observe it over the subsequent months!
