Analysis of first 100000 blocks

After a profitable launch, Frontier crossed its 100,000th block earlier this week. Listed below are some attention-grabbing statistics from these first blocks.

First 50 block occasions (in seconds):

Proper after genesis, the second block took 29 seconds to look, then the following few blocks took 31 and 29 seconds. Not too stunning as miners scrambled with their setups when the final genesis block was identified.

After these first blocks, we see block occasions drop considerably as a consequence of an assault by massive miners, which is the 1 second restrict enforced by the consensus protocol.

Let’s now take a look at the common block time (each 2 hundredth block from genesis to dam 10000):

We will see that the hashing energy is actually hitting the community after the primary few hundred blocks, with block occasions of 1-2 seconds as the issue adjustment algorithm is catching up. This algorithm both will increase or decreases the issue in every block by diff/2048, relying on the block time.

After a number of thousand blocks, we see that the issue will increase a lot that block occasions fall into the vary of 4-5 seconds. After 9k blocks, we’re beginning to attain the goal time of 15 seconds.

Though nobody can ever know for positive whether or not a single miner makes use of a number of Coinbase addresses, assuming they do use the identical one, we now have a reasonably uniform distribution of hash energy over the primary 100k blocks. is 0xe6a7a1d47ff21b6321162aea7c6cb457d5476bca with 11% hashing energy athpoolThe primary mining pool for Ethereum. Then we now have the 2 large miners with round 8% every. The distribution is pretty even after these three, with most miners having lower than 1% of the whole hashing energy.

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

0x580992b51e3925e23280efb93d3047c82f17e038 327  2.2%
0xbb7b8287f3f0a933474a79eae42cbca977791171 496  3.3%

0xe6a7a1d47ff21b6321162aea7c6cb457d5476bca 5775 38.5%

It’s clear right here that ethpool at present has round 40% of the hashing energy, with the second and third largest miners under 4%.

blocks in a row

One other attention-grabbing statistic is to take a look at a steady set of blocks from the identical miner. This may occasionally present some perception into how hashing energy and latency are figuring out for the bigger miners.

Instantly after launch, we observed that the majority blocks in a row had been 6, for instance blocks 1578, 1579, 1580, 1581, 1582 and 1583 had been mined by 0x9dfc0377058b7b9eb277421769b56df1395705f0.

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

This miner mined 5, 4, 3 and a pair of blocks in a row on a number of events, which was not too stunning contemplating he had 21% of the whole hashing energy on the time.

This occurred lengthy earlier than the launch when the issue was rising quickly and plenty of miners had not but joined the community. As hashing energy runs out after block 5000, we’ve not seen greater than 4 blocks in a row for some time.

Nevertheless, probably the most blocks in a row not too long ago have been 10, for instance blocks 103049, 103050, 103051, 103052, 103053, 103054, 103055, 103056, 103057, 103058 by Ethpool. Aside from Ethpool, not one of the miners have greater than 6 blocks in a row.

Keep tuned for extra stats from Frontier Networks as we’ll see it everywhere in the subsequent months!
