¹Ether sales

Purchases can be done on ethereum’s sale site or by using a python tool. The process is that an ethereum’s private public key pair is first generated and the ether address obtained. A password encrypted file with the keys is sent to the buyer which will be needed to spend the ether bought. A bitcoin address can then be generated by assuming the ether address is the SHA256( RIPEMD160() ) of a bitcoin public key. Then bitcoin can be sent to the exodus address with 20,000 satoshis used as the network fee, 10,000 satoshis sent to the corresponding bitcoin address as change and the rest left in the exodus address spendable by the ethereum’s team. Note that the private public key pair for the bitcoin address is not known so the 10,000 satoshis are burned to record the sale order.

²2 addresses anomalies with 0 wei

The following 2 sale orders were sent after the end of the sale period thus no ether was credited but they appeared in the genesis block. This is most probably a bug in the genesis block generator tool.

1. bitcoin transaction sale order:

3d4e17efa6c9e1eac81d950deafc9b4abd905694358bbfd39cedcc82336f1ca5

ether address: 0x5ed3f1ebe2ae6756b5d8dc19cad02c419aa5778b

2. bitcoin transaction sale order:

eb49a9f1e6822938a208c6582797dcb0fdbd4ca0b3dd85c0ebaeb471ecdf2f2e

ether address: 0x00c40fe2095423509b9fd9b754323158af2310f3

³2 anomalies in sale record

Adding on to the discussion above, if a buyer sent 1 bitcoin when the rate is 2,000 ether per bitcoin, his ether address will be credited with 2,000 ether but as 30,000 satoshis is not received by the exodus address the following calculation is used to determine the ether balance.

(bitcoin received at exodus + 30,000 satoshis) * rate

i.e. (99,970,000 + 30,000) * 2,000 per bitcoin = 2,000

As can be observed, if the bitcoin transaction fee and burned bitcoins does not add up to 30,000 satoshis the ether balance might be miscalculated. There were 2 such cases:

1. bitcoin transaction sale order:

a29c2307ccb90675785aa60e25a73aac10efd939b6a5daef4c9e91473177d3c0

ether address: 0xd7ebddb9f93987779b680155375438db65afcb6a

exodus: 5,000,000 satoshis

fee: 10,000 satoshis

burned: 859,110 satoshis

ether: 100.6 ether 2. bitcoin transaction sale order:

b6259f15e892de0b5e05fb2f291263eafb29492a4ac22f8b712fd3b4e41ba82d

ether address: 0xf8f226142a428434ab17a1864a2597f64aab2f06

exodus: 9,000,000 satoshis

fee: 10,000 satoshis

burned: 990,000 satoshis

ether: 172.473 ether

In both cases the buyer sent more bitcoin than needed, saved on fees and had access to the burn address. There is a chance that the buyer had created the bitcoin private public key pair instead of ethereum’s and does not have access to his ether.

⁴Fees anomalies

6 sale orders used a fee of 30,000 satoshis while 2 sale orders used a fee of 10,000 satoshis

Chart interpretation: 75% (y-axis right) of ether sold is purchased with purchase size at most 20% (x-axis) of the largest purchase size or 200,000 ether since in this case the largest purchase size is 1 million.

Bubble chart interpretation: each bubble represents purchases done on each day (x-axis) separated into 5 categories (y-aixs) with the size of the bubble representing the count of purchases in that category. The largest bubble contains 877 counts.
