First look at FUSION Mainnet Parameters:

Total Supply 57344000 FSN(NOW)

Average Block time 15s

Lock-In Lock-Out Block reward 6 FSN

TX Block reward 2.6666666 FSN

TX Block vs LILO Block 9:1 (90% of Tx Blocks vs 10% of LILO Blocks)

Number of collateral FSN for Supreme Node 5000 FSN

Supreme Node can compete for PoS stacking in 9 transaction blocks

Overview of ROI of PoS and SNs:

Annual PoS RoI = Daily PoS RoI * 365

Annual SN ROI = Daily SN Block Rewards * 365

To visualize the PoS and Supreme Nodes ROI there are 3 graphs, an

explanation on these graphs can be found below.

In graph 2.1 and 2.2 we take the 1000, 2000, 3000, 4000, 5000, 8000 and

10000 Supreme Nodes into account. In these graphs, the lines won’t start

from the same point on the X-axis as did in graph 1.

This is because the number of all Supreme Nodes that we take into account

hold a higher percentage of the total supply then for example 10 or 20%.

You can see the math I did to calculate the total supply and the PoS and SN

ROI, in the example I used a number of 2000 Supreme Nodes, as you can

see this number exceeds the 10% and thus far there is no outcome to be

found on the 10% (found on the X-axis).

TOTAL SUPPLY:

NUMBER OF ALL SUPREME NODES * AMOUNT OF FSN REQUIRED FOR

A SUPREME NODE / TOTAL SUPPLY * 100 = PERCENTAGE OF ALL

SUPREME NODE COLLATERAL AND PoS STAKING AS A PERCENTAGE

OF TOTAL SUPPLY (in this case only the Supreme Node holders are solving

blocks)

2000 * 5000 / 57344000 * 100 = 17.43%

PoS ROI:

SECONDS * MINUTES * HOURS / AVERAGE BLOCK TIME X BLOCKS TO

GET REWARD FROM * BLOCK REWARD / PERCENTAGE OF ALL

SUPREME NODE COLLATERAL AND PoS STAKING AS A PERCENTAGE

OF TOTAL SUPPLY * TOTAL SUPPLY * NUMBER OF DAYS IN A YEAR *

100 = PoS ROI

(60 * 60 * 24 / 15 * 0,9) * 2,666666 / (0.1743 * 57344000) * 365 * 100 =

50.48% PoS ROI

SN ROI:

SECONDS * MINUTES * HOURS / AVERAGE BLOCK TIME * BLOCKS TO

GET REWARD FROM * BLOCK REWARD / NUMBER OF ALL SUPREME

NODES * NUMBER OF DAYS IN A YEAR / AMOUNT OF FSN REQUIRED

FOR A SUPREME NODE + PoS ROI

(60 * 60 * 24 / 15 * 0,1) * 6 / 2000 * 365 / 5000 * 100 + 50.48 = 63.09

Three Steps to calculate the Daily FSN rewards:

Because there are 2 different kind of blocks (Tx blocks and LILO blocks),

each step will calculate 2 different reward for PoS Tx (the rewards for Staking

for transaction blocks) and reward for LILO (the rewards for staking for Lock-

In Lock-Out Blocks which require a Supreme Node, but note that LILO reward

is not SN reward).

Step 1: Calculated the daily numbers of blocks

Step 2: Calculated the daily fixed total reward

Step 3: Calculated the daily reward per FSN

1. Determine the Number of PoS Tx Blocks and the LILO Blocks daily

Firstly, calculated the total Seconds in a day by Seconds * Minutes *

Hours, then divided by the time it takes to process each block (15

seconds). The result would be the total number of block during the day

The Total Number of blocks (per day) include both the Tx (transaction)

blocks and the LILO (Lock-In Lock-Out) blocks.

It is given that there ratio between Tx Blocks and LILO BLocks is 9:1

To get number of Tx Block, multiply the number of Total Blocks with % of

Tx Block which is 90%

To get number of LILO Block, multiply the number of Total Blocks with %

of LILO Block which is 10%

2. Get Total Reward Daily for PoS and LILO

Multiply the Tx Blocks per day with the Tx Block reward 2.66666 FSN will

get the Total Reward for PoS Tx Block for that day

The number of both two kind of blocks per day is fix, and the reward for

each block is also fixed, thus the daily reward of Tx Blocks (and LILO

Block) is fixed

But the only variable here is the number of FSN coins is being staked,

thus different number of FSN coins currently staked will get different

reward % per FSN coin

To get the reward for each FSN coin, divide the total daily reward for PoS

Tx blocks or LILO blocks by the corresponding number of FSN used in Tx

or in SN (for LILO blocks)

3. Daily Reward of PoS Tx and LILO per staked coin

To get PoS Tx reward per FSN, divide the Total Tx PoS reward by Total

number of FSN being staked (including both in Tx PoS and those in SNs)

To get the LILO reward per FSN, divide the Total LILO reward by Total

number of FSN being staked in SNs (exclude the number of FSN outside

of Supreme Nodes)

To get the Supreme Nodes reward per FSN, combine the LILO

reward per FSN and the PoS Tx reward per FSN
