Decred wallet

Decred utilizes a unique hybrid consensus mechanism known as ‘proof-of-activity’ (PoA), which is a combination of proof-of-work (PoW) and proof-of-stake (PoS). The primary value proposition of Decred is its ambitious take on governance — an autonomous blockchain network.

As a fork of Bitcoin, the Decred codebase has many similarities with a distinct difference — governance is baked into the protocol. This is known as ‘on-chain governance’, and the development, consensus rules, and future direction of the network are decided by the community of Decred participants.

The main participants in the Decred community include the stakeholders, PoW miners, and community contributors. Splitting the power of consensus validators (i.e., miners and stakers) into two groups is designed to mitigate the ability of small subsets of people to launch chain reorganizations, and also plays a critical role in governance and funding.

For example, block rewards are split between the miners, stakeholders, and Decred Treasury as follows:

• PoW Miners: 60%
• PoS Voters: 30%
• Decred Treasury: 10%

The Decred Treasury funds the development of the Decred network through a community-driven voting mechanism called the Politeia voting and proposals system, which is part of the overarching governance structure.

Concerning governance, miners play a similar role as in Bitcoin, however, stakers in the PoS voting mechanism play a central role to governance. At a high level, the Decred principles for the initial structures in the network are laid out in the Decred Constitution, which can even be changed via Politeia voting.

The overall governance is predicated on a system of ticket-holder voting where users stake (lock-in) DCR — the native Decred token — to purchase multi-purpose tickets. The tickets can be applied to consensus validation via PoS, the Politeia proposal system, and consensus rule changes.

Decred’s dedication to a pure form of on-chain governance is intriguing, and live decision-making on protocol changes — such as the ongoing consensus change vote to support the Lightning Network — should serve as compelling experimentation grounds for decentralized governance.

Examples of community-driven decisions via the ticket voting system include changes to the Decred constitution and which projects to fund using the Decred Treasury. Politeia voting occurs off-chain, while on-chain judgments encompass validating blocks furnished by PoW miners and consensus rules voting.

Decred has an ambitious roadmap that includes ongoing developments such as ticket splitting, an Android wallet, and simple payment verification nodes (i.e., light clients) using compact filters. Similarly, Decred is working on a full-scale implementation of the LN using a port of Lightning Labs’ lnd codebase.

Future developments also include Schnorr signatures and block header commitments.

When you first buy asset, you’re issued with two keys: public and private.

• A public key serves as an address that can be shared with other parties to perform transactions.
• A private key represents a randomly generated number that signs transactions and protects your assets from malicious attacks. If it gets compromised or lost, you won’t be able to access your wallet to spend, withdraw, or transfer your coins.

To safeguard and keep track of your keys, you can use online or offline wallets. Online wallets, also known as hot wallets, store private keys on systems or devices that are connected to the internet. Hot wallets are easy and convenient to use, however, they come with several drawbacks. Besides being susceptible to attacks and a honeypot for hackers, with hot wallets, the custody of private keys is often entrusted to a third party such as a crypto exchange, which means you never have full control over your funds. The safer choice are specialized hardware wallets that store private keys offline. Stealing private keys from a hardware wallet would require physical access to the wallet and corresponding PIN or the recovery phrase. What’s more, with hardware wallet, you don’t need to rely on third party custodians.

Ledger Nano is the industry-leading hardware wallet. With more than five million customers, Ledger Nano wallets have several layers of security that protect private keys, and hence your assets:

• Your private keys are stored on secure element chips.
• A PIN code and a 24-word recovery phrase are required to access the wallet.
• Ledger Nano cold wallets have been built using highly durable materials for protection against physical damage.

With full isolation between private keys and your computer/mobile, Ledger Nano hardware wallets keep your keys secure and give you complete control over your tokens.
