What is Solarcoin?

SolarCoin is an alternative digital currency that works like air-miles for Solar electricity generation.
For more information on Solarcoin refer to https://solarcoin.org
And watch the video here.

What needs to be done ?

Solarcoin wallet has at its core Bitcoin's Bitcore technology. The current version of Solarcoin found here uses version .04 of Bitcore. It needs to be updated to Bitcore version 0.14.1

Development requirements

Solarcoin is a standard clone coin with the following unique aspects:
1. Ability to add a 523 character message to each TX transaction. This capability is inherited from Florincoin.
2. POST consensus algorithm. The POST algorithm is inherited from Vericoin. White paper here.

Please include the bitpay features for copay.io support as well, the various indices (address, spent, unspent) and the new rpc calls - https://github.com/bitpay/bitcoin/tree/0.13-bitcore



Please post your outcome on the open repository at https://github.com/.
Ideally updated compiled versions of the Linux, MacOS and Windows QT wallets would delivered as well.  Ideally they would also be developer signed.

Prizes to go

The best solution will get the prize of 10,000 SLR (approximately $ 1,900) . The rest of the contributing members will share 15,000 SLR (approximately $ 2850), with the sum of one prize not exceeding 5,000 SLR (approximately $ 950). The amount of each award will be calculated individually, based on the quality of the work provided.

Please note the SolarCoin foundation is also offering SLR 20,000 added to the 1st prize winner to deliver a solution that is compiled and functional.

Any reason why the development team behind SolarCoin can't handle this? I love that this is a project and there's a prize and all, but find it confusing that it's not being handled by SolarCoin's own team.
