Principle 3 Value as Incentive
Summary
TLDRThis video script explores the third design principle of blockchain: value as an incentive. It explains how blockchain aligns incentives of stakeholders using tokens like Bitcoin, promoting behaviors that benefit the network and build reputation. Satoshi Nakamoto's programming rewards self-interested actions that protect and develop the blockchain, countering destructive incentive systems of the past. The script also touches on Bitcoin's monetary policy, capped at 21 million, and the potential for new financial instruments and applications in virtual worlds, emphasizing the implications of financial incentives for collaboration and innovation.
Takeaways
- π Blockchain uses a token of value, like Bitcoin, to incentivize behaviors that benefit the network and build a person's reputation.
- π‘ The alignment of incentives in blockchain systems contrasts with traditional internet structures where power is concentrated in large corporations.
- π¦ The 2008 financial crisis highlighted the negative consequences of incentive systems that reward short-term thinking and risk-taking in large banks.
- π‘οΈ Blockchain technology addresses issues like Sybil attacks by making it economically unattractive to create multiple identities, thus maintaining network trust.
- π° Satoshi Nakamoto's protocol rewards miners with Bitcoins for creating blocks, which also serves as a disincentive for bad behavior as miners are invested in the network's success.
- π The Bitcoin reward for mining blocks halves every four years, which has been effective in rewarding early adopters and maintaining the integrity of the blockchain.
- π€ The self-interest of miners in choosing the longest chain to mine on helps to solidify the blockchain and keep the network in consensus.
- π On the blockchain, a person's identity is inherent and recorded with their actions, which is a departure from traditional forms of identity verification.
- πΌ The Bitcoin blockchain's monetary policy is hard-coded into the software, capping the supply at 21 million, which helps protect against inflation and currency devaluation.
- π The blockchain opens up possibilities for new financial instruments and applications, including those for virtual worlds and smart contracts.
- πΌ The divisibility of Bitcoin to eight decimal places enables micropayments and smart contracts, which are particularly useful for the Internet of Things.
Q & A
What is the third design principle of blockchain technology discussed in the script?
-The third design principle discussed is 'value as an incentive,' which means that blockchain aligns the incentives of all stakeholders and uses a token of value to promote behavior that benefits the entire system.
How does blockchain technology align incentives to promote good behavior?
-Blockchain technology uses a token of value to incentivize behavior that benefits the network as a whole, and it builds a person's reputation within the system. This incentivization encourages participants to act in ways that maintain the health and integrity of the blockchain.
What problem does the value incentive system solve that was prevalent in the early internet era?
-The value incentive system solves the problem of a destructive incentive system where power was concentrated in large corporations and banks, leading to behaviors like predatory lending and exploitation of user data, which contributed to the 2008 financial crisis.
How did Satoshi Nakamoto program the blockchain to reward people who work on it and use its tokens?
-Satoshi Nakamoto programmed the blockchain to reward participants with Bitcoins for their contributions, such as mining new blocks. This reward system encourages participants to act in their self-interest, which in turn benefits the blockchain network.
What is a Sybil attack, and how does the blockchain design address it?
-A Sybil attack is when a node forges multiple identities to seem like different people, undermining the trust in a peer-to-peer network. The blockchain design addresses this by making it economically unbeneficial to acquire extra identities through its consensus mechanism and token rewards.
How does the blockchain protocol reward early adopters and miners?
-The protocol rewards early adopters and miners with a set quantity of Bitcoins for mining new blocks. Initially, miners received 50 Bitcoins per block, and this reward has halved every four years, incentivizing miners to invest in the platform's success.
What is the significance of the longest chain in the blockchain network?
-The longest chain represents the greatest amount of work and is considered canonical by the network participants. This consensus on the longest chain solidifies the blockchain and ensures that all participants are on the same page.
How does the blockchain technology leverage a person's reputation online?
-Blockchain technology allows a person's identity to be inherent and recorded with their actions. This means that a person's reputation is built and can be leveraged within the blockchain network, providing a new dimension of trust and accountability.
What is the monetary policy programmed into the Bitcoin blockchain, and why is it important?
-The Bitcoin blockchain has a monetary policy that caps the supply of Bitcoins at 21 million, to be issued over time. This policy is important as it makes the currency more secure, immune to counterfeiting and theft, and resists inflation, providing a stable store of value.
How does the divisibility of Bitcoin facilitate transactions in the internet of things?
-Each Bitcoin is divisible to eight decimal places, allowing users to combine and split value over time in a single transaction. This divisibility enables the setup of smart contracts for micropayments, which is ideal for the internet of things where devices need to exchange information and perform transactions.
What are the implications of using value as an incentive in blockchain for collaboration and innovation?
-Using value as an incentive in blockchain provides financial motivation for effective collaboration and the creation of new services and products. It also means that a person's reputation becomes valuable and trackable, potentially reducing bad behavior and encouraging positive contributions to various fields, including sustainable energy and open-source software development.
Outlines
π° Value as Incentive in Blockchain Design
The third principle of blockchain design is the use of value as an incentive mechanism. This principle aligns the interests of all stakeholders, encouraging behaviors that benefit the blockchain ecosystem through the use of tokens like Bitcoin. Satoshi Nakamoto's software rewards participants for contributing to the network, which also enhances their reputation. The system addresses the issue of destructive incentive structures prevalent in traditional internet and financial systems, exemplified by the 2008 financial crisis. Blockchain combats issues like Sybil attacks by making it economically unviable to create multiple identities. The consensus mechanism and Bitcoin rewards compel participants to act with integrity, ensuring the long-term success of the platform. Miners, for instance, are incentivized to invest in the best equipment and maintain the ledger, as they own and are invested in the success of Bitcoin.
π Reputation and Security in Blockchain Systems
This paragraph delves into the importance of reputation and security in blockchain technologies. Unlike traditional systems, blockchain allows for the leveraging of one's reputation online, with identities and actions inherently recorded on the blockchain. The Bitcoin blockchain, in particular, is designed to preserve value by incorporating a fixed monetary policy into its software, capping the total supply of Bitcoins at 21 million to prevent inflation and ensure security against counterfeiting and theft. The divisibility of Bitcoin to eight decimal places enables the creation of smart contracts for micropayments, which is particularly useful for the Internet of Things. The implications of using value as an incentive in blockchain are profound, fostering financial incentives for collaboration and the creation of new financial instruments and applications. This could lead to innovative solutions such as real-time payments for sustainable energy generation and contributions to open-source software projects.

in these lessons we're looking at the
seven design principles underlying
blockchain our third principle is value
as an incentive
what does this mean well the way
blockchain is set up it aligns the
incentives of all stakeholders it uses a
token of value like a Bitcoin to promote
Behavior benefiting the blockchain as a
whole
the behavior also builds a person's
reputation
Satoshi Nakamoto programmed the software
to reward people who work on it and use
its tokens
when everyone has a stake in the network
people make sure that it stays healthy
problem this solves is a destructive
incentive system in the first air of the
internet power was concentrated in large
corporations they could extract enormous
value from the system making them more
powerful still large Banks nearly broke
the financial system because their
leadership was rewarded for risk taking
and short-term thinking remembered 2008
that's how the incentives were set up
the quarterly report was King this
caused a host of bad behaviors including
predatory loans targeting the poor
likewise
large.coms pretended to offer something
for nothing
they advertised free services and Retail
search social media and the real unseen
cost was user data which they exploited
to boost revenues
but whenever these firms get hacked
consumers are left to deal with the
stolen credit card and their bank
account information the blockchain
Breakthrough is in using programming to
incentivize good behavior Satoshi
recognized that people act in their own
self-interest so he needed to harness
that self-interest to build and protect
the blockchain
one of the things he had to defend
against was the so-called civil attack
that's when a node forges multiple
identities making one person seem like a
bunch of different people
this makes the peer-to-peer Network less
trustworthy you don't know whether
you're dealing with three parties or one
party using three identities
on the other side of things it also
makes it much harder to prove you are
who you say you are to fight civil
attacks Satoshi didn't make it
impossible to acquire extra identities
instead he made it so that there was no
benefit in doing so he programmed the
source code so that no matter how
selfishly people acted their actions
benefited the system
the resource requirements of the
consensus mechanism combined with
Bitcoins as a reward compel participants
to do the right thing to act with
integrity
civil attacks no longer make economic
sense when minors create a block and
Link it to the previous one The Miner
who completes the blog first gets a set
quantity of Bitcoins for their efforts
satoshi's protocol rewarded early
adopters handsomely with Bitcoins for
the first four years miners received 50
Bitcoins for each block
every four years the reward per block
has halved 25 Bitcoins
12.5 Bitcoins and so on
and because they now own Bitcoins the
miners are invested in the platform's
long-term success
so they buy the best equipment to run
mining operations spend energy as
efficiently as possible and maintain The
Ledger
Bitcoins also represent partial
ownership of the blockchain itself it's
not just incentive to mine and transact
with others by owning and using Bitcoin
participants are financing the
blockchain's development here's an
example of how making a selfish Choice
benefits the network and it involves
miners every so often different miners
find two equally valid blocks of equal
height
this means the rest of the miners need
to choose which block to build on next
they generally pick whichever they think
will win rather than building on both
otherwise they'd have to split their
processing power and all the electricity
they're providing between these Forks
well that's a losing strategy
the longest chain represents the
greatest amount of work so participants
choose it
as Canon this solidifies the blockchain
and keeps everybody on the same page all
because every Miner wants to back the
right horse
by acting in their own self-interest
miners serve the peer-to-peer Network
and that affects their reputation
before blockchain Technologies people
couldn't easily leverage the value of
their reputation online even offline our
identities are multi-faceted and our
reputations are different among
different groups we keep documents to
prove our ID like passports and and a
driver's license
but on the blockchain your identity is
inherent and recorded with your actions
the Bitcoin blockchain also preserves
value by programming its monetary policy
right into the software
this means the currency is more secure
not only is it immune to counterfeiting
and Theft
but it also resists inflation Satoshi
capped the supply of Bitcoins at 21
million to be issued over time
the current rate of mining is six blocks
per hour
since the amount of Bitcoins awarded for
mining a block is halved every four
years those 21 million Bitcoins should
all be in circulation around the year
2140.
this should guard against hyperinflation
and currency devaluation and currencies
are not the only asset we can trade on a
blockchain the sky's the limit really
new financial instruments are possible
from proof of asset authenticity to
proof of property ownership
there might also be blockchain and
Bitcoin applications for Virtual Worlds
such as the ones described in books like
Neil Stevenson's snow crash or Ernest
Klein's Ready Player One
unlike fiat currency each Bitcoin is
divisible to eight decimal places
and this lets users combine and split
value
over time in a single transaction
that means that users can set up smart
contracts to measure the use of a
service and eke out tiny fractions of
payments or micro payments
that kind of metering is great for the
internet of things when the physical
world becomes smart and starts
exchanging information and doing
transactions so what are the
implications of using value as an
incentive
with blockchain people have a financial
incentives to collaborate effectively
and to create just about anything
if your reputation is valuable and
trackable online discussion groups won't
be inundated with trolls bad behavior
will cost too much
homeowners could receive real-time
payments for using solar panels to
generate sustainable energy for the
network
software developers on open source
projects could pay contributors for
acceptable code
imagine all that and more
