HBC-001: What is blockchain
In video one for the Helsinki Blockchain Center, I talk about what blockchain is for.
People often ask, "what is blockchain", but that is the wrong question, because most of us ...don't need to know how something works, we just need to know what we can do with it.
Blockchain is about enabling decentralized digital ownership, that is, without having to rely on a central party to manage the ledger recording this ownership.
And ownership is ultimately about control - if you own something, you have control over it in a manner that no one else does, and you have control over whether you maintain the ownership, or transfer it to someone else.
Why would this be important?
If you outsource your ownership to a centralized authority, you have lost some control. Transactions you wish to undertake with your property can be censored by the authority.[+] Show More

In video two for the Helsinki Blockchain Center, I talk about why blockchain is of significance.
The significance of blockchain arises from its decentralization of ownership, which is not a new ...thing - for most of the existence of humanity possessions have not been centrally controlled. But in the digital world this is not the case - most digital assets are managed by a central authority.
There are three facets to ownership that should be considered. It requires:
- a thing to own,
- someone to own it, and
- the possibility of transacting with the owned item
By focusing on one of these more than the others, you find that different blockchain use cases emerge.[+] Show More

The eternal "not quite a beginner question" is about permissioned, permissionless, public, and private blockchains.
Not all blockchains are made alike. In this video I look at the spectrum of "permissioned ...versus permissionless" and "private versus public" blockchains, which defined a field of possibilities in which a blockchain may operation.
At one extreme you have public permissionless blockchains such as Bitcoin, where anyone can participate in any manner that they like, provided they follow the protocols and rules of the system.
At the other extreme you might have a private permissioned blockchain run by a consortium of companies, in which the general public are not aware of its existence, and members of the consortium have to approve the addition of new accounts on the blockchain.
In practice, most systems fall somewhere between the two, but there is mounting evidence that provided you can provide the right governance and incentive structure, open and permissionless provides more value to the ecosystem.[+] Show More

The key date for the appearance of blockchain is 31 October 2008 (I accidentally say 2009 in the video - can't believe I said that wrong!), when an anonymous person ...or persons going by the name of Satoshi Nakamoto published the paper, "Bitcoin: A Peer-to-Peer Electronic Cash System".
Nakamoto didn't use the term "blockchain" in the paper, but the system described remains one of the clearest examples of what a blockchain is and how they function.
Naturally, as is always the case with invention, there were many components that came before, however, if recombining existing building blocks creates a system that exhibits unexpected properties, it is definitely something new.
What is now known as Nakamoto consensus - the incentivization of a decentralized system through proof of work - result in a wide range of unexpected properties.
So unexpected that we're still analyzing what the full meaning behind them is.[+] Show More

If you start hanging around in Blockchain-related forums, you'll see the term "consensus" cropping up a lot in discussions.
This is because reaching a common view of the truth is possibly ...the core purpose of blockchain.
And consensus is hard if you've got a lot of different participants, and none of them has absolute power over the others.

Identity is an essential feature of blockchain. So essential that describing it as a 'feature' feels like trivializing it.

Ownership is a more complex concept than you would think at first.
When you own a small object, such as a coin or a knife, it is usually because it is ...in your possession. But you can't carry around a house or a piece of land. So we use a ledger or a registry for that.
These registries used to be maintained on paper, but now it is done digitally. And most such registries are maintained by a central authority. For example, land registries.
You can also own virtual assets. For example, patents aren't tangible. But your ownership of a patent is recorded in a ledger held by the relevant patent office.
Blockchains are also ledgers recording ownership, typically of virtual property. But they differ from the previous registries mentioned, in that there is no central authority.
So although they are digital ledgers recording virtual assets, in some ways your ownership of those assets is more similar to the ownership of small physical objects.[+] Show More
