| properties: * Decentralization (defined as the
| system being able to run in a scenario where each
| participant only has access to O(c) resources, i.e.
| a regular laptop or small VPS) * Scalability (defined
| as being able to process O(n) > O(c) transactions) *
| Security (defined as being secure against attackers with up to
| O(n) resources) In the rest of this document,
| we'll continue using c to refer to the size of
| computational resources (including computation, bandwidth and
| storage) available to each node, and n to refer to the
| size of the ecosystem in some abstract sense; we assume
| that transaction load, state size, and the market cap of
| a cryptocurrency are all proportional to n. The key challenge of
| scalability is finding a way to achieve all three at the
| base layer.
