This blockchain scripting contest is a way to raise awareness about the possibilities and powers of the scripting mechanism integrated in the Bitcoin protocol.

Every trial will be about a non-standard transaction output (scriptPubKey) broadcast by me and funded with a given amount. Objective of the trial is to find an appropriate script (scriptSig) that will succesfully resolve the stacked scripts, as requested by the bitcoin protocol. The amount in the tx output is the award of the trial and can be claimed at will.

The difficulty of the trials will increase in each step.

Recommended Toolchain to build and broadcast a custom transaction:

Documentation: Transactions, Raw Transactions API, Scripts and OPcodes reference.

Have fun!

PS: Any amount sent to the address 1JHCn9wLLXHc4yfo968FrT259Um2hzeUpy will be used to fund the next trials.
