+CROWN PRODUCT ROADMAP
+1.	CORE UPGRADES
+Bringing in all useful features, enhancements, bug fixes, and performance improvements from the bitcoin core codebase. Some of these include:
+A.	Compiler updates
+B.	Memory performance improvements
+C.	Block and transaction handling
+D.	Build system updates
+E.	Unit tests
+F.	Transaction malleability, fee sniping and other potential vulnerabilities fixes
+G.	Bitcoin Scripting language upgrade
+H.	P2P and network protocol optimization
+I.	Wallet improvements (ex. All transactions will use Instant Send)
+2.	GOVERNANCE
+The voting system that funds community proposals and network development. New features, new voting nodes, and more!
+A.	Moving unspent proposal funds to the next budget
+B.	Implement new Systemnode voting ability
+C.	Bug fixes
+D.	In-wallet proposal notifications
+3.	PROGRESSIVELY EVOLVING CONSENSUS
+The part of the network that provides agreement on the order and validity of transactions is the consensus algorithm. Crown is currently secured by Proof-of-Work (PoW) through Bitcoin SHA256 merge-mining, which is Phase 1 of the process to a more energy-efficient form of network agreement and security. Phase 2 is the switch from PoW to Proof-of-Stake (PoS). Phase 3 is the implementation of a newer algorithm that is currently being researched and developed.
+A.	Migrate network to the PoS algorithm
+B.	Increase node incentives for Masternodes and Systemnodes
+C.	Test and implement new algorithm once R&D and testnet auditing are complete
+D.	Contracts Notarization
+4.	REGISTRATION
+To become a provider in the Crown ecosystem, an application service must be registered in the Crown blockchain. For this goal, Crown Platform will provide registration agents and other infrastructure.
+A.	Community Delegated Agents
+B.	Services Registration
+C.	Identity Verification
+5.	API
+The Crown Platform API will be an access point for transacting on the network. With this implementation, network businesses and service providers will have programmatic access to the blockchain, providing easy hookup to user ID verification and payment mechanisms. Developers will be able to program dApps in any language and enable features of the Crown blockchain right in their code!
+A.	RPC updates
+B.	REST implementation
+C.	Services payment hooks
+D.	Registration system integration
+6.	DATA STORAGE
+Decentralized file storage integration like Storj, filecoin, using IPFS or another file system designed for encrypted peer-to-peer distribution.
+A.	dApps hosted on Crown Platform will be able to securely store and distribute files
+7.	TREZOR (95%)
+Integration of support the Crown token into a hardware wallet will be a huge advance for CRW token holders in secure cold storage options. Previously only an offline computer or mobile phone or a paper wallet were the only options. The next Trezor firmware update will include CRW support!
+A.	Crown core software updates
+B.	Hardware wallet code updates
+C.	Firmware update
+8.	NATIVE WALLET INTERFACES
+The interaction tool between users and the blockchain, the native software wallets present Crown to the public. In an effort to evolve the professionalism and usability of our features, a professional designer has been brought on to design a new UI that will match the current generation of branding.
+A.	A complete redesign of the native software wallet interfaces on all platforms by an industry professional
