Full transparency, I was fortunate enough to have participated in one of the private sale rounds but this has in no way (fully) influenced why I am so incredibly bullish. Read on…
Polkadot is a sprawling blockchain platform with lofty aims, ambitions, and capabilities. Sure, there are plenty of big words thrown around when describing what Polkadot can do, but let’s drill down to the essentials.At its core, Polkadot is a highly scalable and fully interoperable blockchain protocol upon which the next generation of the web is being built. When saying this exact sentence to my wife, her response was “fuck off Daniel”. So if you, like she was (and still is), are already lost at the word “interoperable”, fear not. We’re going to unpack that concept, along with several others, by starting off with an explanation of Polkadot’s most important concept: ushering in the decentralised web era.Despite these applications, blockchains are hampered by a major roadblock: they don’t play nicely with others. This means they can’t interoperate.
Why should that matter? Because when platforms are non-interoperable, the tendency is to grow one network into monopolistic proportions. Need proof? Look no further than Google, Facebook, and Amazon.That’s why Polkadot’s core mission is to create and connect a new web of decentralized blockchains, a vision of tomorrow’s internet they call web 3.0. In this new version of the web, trust is implicit in the network, individuals have more power than corporations and governments, and people own their data.
As the Polkadot team puts it in their,In a nutshell, Polkadot bridges different blockchains, along with giving developers the tools to build new ones, to create a decentralised web of blockchains.
Every time a blockchain is created on or around the Polkadot standard, it becomes a parachain. The Polkadot blockchain itself is built using Substrate, a broad toolset for building blockchains and digital assets.
When Substrate-built parachains run on Polkadot, they’re conferred all of the advantages of the Polkadot Network, like advanced consensus and high throughput scalability.Building a standalone blockchain network from scratch is really tough. It’s resource and skill intensive, not to mention you’ll fall into the whole silo category Polkadot is making obsolete. By using Substrate to build a Polkadot-connected parachain, you get simple tools out of the box, helping you go from ‘nocoiner’ to blockchain-based real quick.
Question: Just how quickly can developers launch custom blockchains using Substrate?
Answer: 15 minutes.
Yep, that’s how long it took Polkadot founder Gavin Wood to unwrap a brand new Macbook Pro and create a parachain.Because Polkadot has its own consensus algorithm (Proof of Authority), incoming blockchains can simply port in, thus taking advantage of what’s called pooled security. Pooled security takes the onus of creating a secure blockchain off the shoulders of parachains, and instead places it on the Polkadot Relay Chain.Since parachains benefit from the Polkadot Relay Chain’s pooled security and sharded scalability, they can instead focus on what matters: their own specialisation. Because independent blockchains are forced to be profitable to survive, they’re forced to build generally rather than specifically. Polkadot lets blockchains get weird, communicate with each other, and swap smart contract data securely and privately.Connecting to the Polkadot Relay Chain enables blockchains to send transactions between one another seamlessly, thus providing true interoperability between networks. For developers, this is especially tasty, as it allows them to build applications using smart contracts and features from different parachains. For DeFi applications, the era of full crosschain swaps is finally upon us.
These are the core features powering the Polkadot paradigm:
Polkadot token, or $DOT for short, is the network’s native digital asset for governance, staking, and bonding. Let’s take them one at a time.
But, just because you could say that doesn’t mean you’re correct. In fact, bonding is quite different from the ICO crowdfunding model.
The ICO model merely trades one token for another. If you want to participate in X ICO, all you do is send ETH or USDT, or some other token to the contract, and you’ll receive Y token in return. Problematically, this doesn’t encourage value to stay on the network, nor does it encourage value to the network’s native token.
Why not? Because the main incentive in traditional ICOs is to dump the crowdfunded tokens into something more stable, like a stablecoin. Countless projects swore to hodl their ETH after raising ICO funds in 2017, only to sell them off as the market cascaded in 2018.Polkadot avoids this scenario with the bonding mechanism. In the Polkadot realm, ICOs are called IPOs, short for Initial Parachain Offering.To join the Polkadot as a parachain, new projects need to raise an amount of DOT from the community. The raised $DOT is bonded (locked) to the network for a predetermined amount of time — the longer in duration the parachain slot is, the more $DOT must be bonded.At the end of the parachain slot duration, the bonded DOT is released back to their owners, whereupon the said parachain can either apply for another slot, or withdraw from the network.As you can see, the bonding mechanism requires $DOT to be locked rather than sold, thus adding value to the network and $DOT token.Under the hood, Polkadot has a powerful consensus mechanism that guarantees security. To keep the mechanism running, the community plays a crucial role through the act of $DOT token staking.
Every transaction passing through the Polkadot Relay Chain needs to be validated. $DOT token holders who do the validating are called…err… validators.
As a validator, you stake your $DOT tokens on the network to do the job of confirming transactions. Basically, you’re saying that transactions on your watch are all true, and are putting up your stake as a guarantee.At the end of the day, it’s users who are in control of the Polkadot network. Unlike centralised tech corporations who operate in the service of their shareholders, Polkadot users directly make decisions about the network.
To make those decisions and signal ‘skin in the game’, those users must hold $DOT tokens. Additionally, in a move similar to bonding and staking, users voting on community referenda do so by locking their $DOT tokens with their vote.
Locking your tokens in with your vote signals your seriousness about the vote, and keeps community members from selling their votes.Now, you might be tempted to say that Polkadot governance can favour big shareholders over smaller DOT wallets. Thankfully, that simply isn’t so because of a unique mechanism called time locking.
With time locking, users with a small amount of DOT tokens can leverage a larger stake in the governance mechanism by locking their DOT into referendum votes for longer periods of time.⏳ Time Lock Example:
Alex: Votes `No` with 10 $DOT for a 128 week lock period ⇒ 10 * 6 = 60 VotesSimon: Votes `Yes` with 20 DOT for a 4 week lock period ⇒ 20 * 1 = 20 VotesJonathan: Votes `Yes` with 15 DOT for a 8 week lock period ⇒ 15 * 2 = 30 VotesIn this way, community members invest their opportunity cost into their vote, thereby keeping small holders in play and mitigating centralisation.Amongst the many exciting new projects are several major blockchains occupying the current top crypto market cap spaces. Ontology, a blockchain for decentralized identity services, is one of them:
Although Polkadot can be harnessed for literally any blockchain application out there, the vast majority of those being built today are in the DeFi sector. Why? Because Polkadot offers the benefits of Ethereum 2.0 today, rather than in several years from now.
