<span id="example-1---exchange-bootstrapping"></span>
=== Example 1 - Exchange bootstrapping ===

A coin could be created to incentivize liquidity on decentralized exchanges. The coin would enforce a system that brought together multiple blockchains (the service) and gave away rewards to help do it (the reward.) This could be done using probabilistic collateral contracts or something like BlockNet.

'''Shared service:''' Increased adoption of an exchange for its users.

<span id="example-2---search-engines"></span>
=== Example 2 - Search engines ===

A coin that rewards users for processing information in torrent files to find files that all the participants want in accordance to some formula (they use bandwidth to randomly check files in some hashed set of files and the more bandwidth contributed, the faster the torrents can be “searched.”)

'''Shared service:''' Finding results for a search query that all users need.

<span id="example-3---ddosing-people"></span>
=== Example 3 - DDoSing people ===

A coin that rewards users for attacking SSL-enabled websites. The more people who use the coin, the more powerful DDoS attacks become, the more users it gains, the more the rewards are worth.

'''Shared service:''' More powerful DDoS attacks.

<span id="example-4---ledgers-name-registries-permissions-etc"></span>
=== Example 4 - Ledgers, name registries, permissions, etc ===

* A coin that reward users for securing the ledger and the more people mining it, the more secure it becomes.
* Any new cryptocurrency that improves on the process in some way like scaling, privacy, decentralization, security, smart contract DSLs, etc.

'''Shared service:''' High security ledgers.

<span id="example-5---math-problems"></span>
=== Example 5 - Math problems ===

Certain classes of problems may be outsourceable and easily verifiable. If all the parties cared about the solution this would be a good use-case but it differs from something like Golem since the service is shared with everyone.

'''Shared service:''' Access to new knowledge

<span id="example-6---trustless-software-bounties"></span>
=== Example 6 - Trustless software bounties ===

A ledger that allows for arbitrary computations to be run for the purposes of running deterministic software builds against a number of conditions would allow smart contracts to be written that could specify trustless bounties for algorithmic speed improvements or security vulnerabilities.

'''Shared service:''' Trustless software bounties
