If you do not trust seed generators and do not believe your random keyboard smashing is random enough, you can use a dice to generate a random, perfectly distributed IOTA seed.
Just follow the instructions below and write down the seed while you are throwing your dice.
Note that this can be tedious, as between 162 and 243 dice rolls are required to generate the whole seed.
- Roll your dice two times (remember the order of the results).
- If the first roll is a 6, or if the first roll is a 5 and the second roll is 4-6, roll a third time.
- Look up the character in the table below
- Repeat until your seed has 81 characters
| First roll | Second roll | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|---|
| 1 | A | B | C | D | E | F | |
| 2 | G | H | I | J | K | L | |
| 3 | M | N | O | P | Q | R | |
| 4 | S | T | U | V | W | X | |
| 5 | Third roll 1-2 Third roll 3-4 Third roll 5-6 |
Y | Z | 9 | A B C |
D E F |
G H I |
| 6 | Third roll 1-2 Third roll 3-4 Third roll 5-6 |
J K L |
M N O |
P Q R |
S T U |
V W X |
Y Z 9 |
The method I describe above is fast, just takes a few minutes. Note that I meant roll two dice at once, not separate rolls of one die. Have used this method twice, and it requires about 100 rolls of two dice. To further avoid detectable patterns in the generation of the seed: (i) the nine grid squares to block out should be the pairs (1,1), (2,2), etc. plus (1,6), (2,5) and (3,4). This excludes all the dice numbers about equally (ii) fill in the remaining grid squares with A-Z and 9 in random order, and (iii) use different brands and sizes of 6-sided dice and mix and match them on the different rolls. For example I used 7 different pairs from 3 different dice brands, for a total of 14 dice to choose from on each roll. (i) and (iii) help avoid predictability from dice that might tend to land on certain numbers more than others due to being weighted imperfectly. In addition shake the dice a lot before each roll, and roll them on a surface/in an area where they can roll and bounce around a lot. I prefer rolling dice to relying on a computer-generated seed because with dice I can see for myself that it's random i.e. the mechanics of generating the seed are out in the open and simple. Also it is impossible for anyone to steal the seed electronically as a result of the generation method.
