Numbers we worked out ourselves
These are not published figures. They are arithmetic on the cited numbers above, shown here with the method so anyone can check it or disagree with it.
- 75% to 99.98%
The share of three-party remittance transactions that would touch more than one shard, as the shard count rises from 2 to 64. Method: with a sender, a conversion provider and a recipient assigned independently and uniformly across n shards, all three land together with probability 1/n squared, so the cross-shard share is 1 minus that. Ours, not measured, and uniform assignment is a generous assumption: real networks concentrate load, which makes it worse rather than better. It is drawn to show the shape of the effect the cited sharding research reports.

Our own estimate of what closing the gap would return to families each year. Method: (6.36% − 3%) × $905bn. It is arithmetic on the two cited figures above, not a published number, and it assumes the average rate applies evenly across all flows.

What each provider keeps out of $200 on the US to Mexico corridor. Method: the fee, plus the gap between the mid-market rate and the rate applied, converted back to dollars. Wells Fargo, $6.00 + (18.75 - 18.54) x 200 / 18.75. Delgado Travel, the same sum on 18.74 and 18.37. Both rates are cited above; the subtraction is ours. The split matters more than the total: the fee is the same $6.00 on both, so it is the larger share of each, and the whole $1.71 gap between the two providers is exchange rate margin.

Average transactions per second a network carrying all global remittance volume would have to sustain, across assumed average transaction sizes from $500 down to $100. Method: $905 billion divided by the assumed size, divided by 31,536,000 seconds in a year. The flows figure is cited above; the division is ours, and the fivefold spread comes entirely from the assumption, not the arithmetic. The realistic target is roughly a tenth of this, because no single architecture carries the whole market.
