The proof of stake system is attracting a lot of attention these days, with Ethereum switching over to this system from the proof of work system.

MD:
The Bitcoin (i.e. blockchain) people claim it’s main asset is that there is no central authority. But there is certainly a central process or “switching over” wouldn’t be possible. The RFC process of the entire internet has shown us it is possible to have a universally accepted process … without cryptography and without block chains and without a central authority. The DNS (Domain Name System) is a distributed database protocol that has many attributes useful for a distributed database system with no central authority. And of course it has some serious issues.

HN: Proof of stake is an alternative process for transaction verification on a blockchain. It is increasing in popularity and being adopted by several cryptocurrencies. To understand proof of stake, it is important to have a basic idea of proof of work. As of this writing, the proof of work method is used by Bitcoin, Ethereum and most other major cryptocurrencies.

MD: At MD we know for “real” money you don’t need “proof” of anything. What you need is universal transparency to things. Those things are the “creation and delivery on time and space spanning promises made by traders.”

HN: Proof of work

Proof of work is a mining process in which a user installs a powerful computer or mining rig to solve complex mathematical puzzles (known as proof of work problems). Once several calculations are successfully performed for various transactions, the verified transactions are bundled together and stored on a new ‘block’ on a distributed ledger or public blockchain. Mining verifies the legitimacy of a transaction and creates new currency units
.
MD: Digging a hole and filling it right back in is work … totally useless work. A money system that relies on useless work is an open admission that the “money” itself has zero value. Rather it “represents” something of “perceived” value … and that perception must be universal. Thus, here we have open admission of a failure of the “proof of work” scheme.

HN: The work must be moderately difficult for the miner to perform, but easy for the network to check. Multiple miners on the network attempt to be the first to find a solution for the mathematical problem concerning the candidate block. The first miner to solve the problem announces their solution simultaneously to the entire network, in turn receiving the newly created cryptocurrency unit provided by the protocol as a reward.

MD: This is admission that this scheme is even more stupid than using precious metals as money (being proof of work). At least with precious metals all miners are creating something of “real” value. And when someone else gets there first, they don’t lose their work.

HN: As more computing power is added to the network and more coins are mined, the average number of calculations required to create a new block increases, thereby increasing the difficulty level for the miner to win a reward. In proof of work currencies, miners need to recover hardware and electricity costs. This creates downward pressure on the price of the cryptocurrency from newly generated coins, thus encouraging miners to keep improving the efficiency of their mining rigs and find cheaper sources of electricity.

MD: Another open admission of the absurdity of this process. We see the predictable today. So-called “miners” use exotic bots to “steal” computer cycles from internet users. They sneak onto government owned super computers. They also create faster machines that quickly obsolete existing machines thus wasting more “real” resources. It’s not unusual for brand new state of the art ASIC and FPGA based machines to pay themselves off in one to three months … and be totally obsolete in three to six months. In the meantime, they make so much noise they drive their owners out. But they do have an advantage. They use so much electricity, they can mask a hidden marijuana operation.

HN: Bitcoin is an example of a cryptocurrency that uses the proof of work system.

MD: There is no need for the “currency” to be encrypted. In fact, in a “real” money process, the traders, the process, and the terms must be in universal plain view … and unchangeable. This is easily accomplished with simple universal hashing protocols.

HN: Mining rigs in a bitcoin mining facility.

Proof of Stake

Unlike the proof of work system, in which the user validates transactions and creates new blocks by performing a certain amount of computational work, a proof of stake system requires the user to show ownership of a certain number of cryptocurrency units.

MD: In a “real” money system, new traders creating money don’t have to be existing large money changers. Here is open admission that the “proof of stake” system copies a myth from our existing flawed (rigged actually) Medium of Exchange (MOE) process.

HN: The creator of a new block is chosen in a pseudo-random way, depending on the user’s wealth, also defined as ‘stake’. In the proof of stake system, blocks are said to be ‘forged’ or ‘minted’, not mined. Users who validate transactions and create new blocks in this system are referred to as forgers.

MD: In any MOE system, counterfeiters are often “forgers”. Interesting choice of terms isn’t it. Presumably they’re using the “forge” metaphor where existing metal is hammered into different shapes. But there is also the “faking” form where signatures and whole documents are forged. Any MOE process must prevent this. In a “real” MOE process, it is the only leak possible and is mitigated by total transparency of the money creation and destruction activity.

HN: In most proof of stake cases, digital currency units are created at the launch of the currency and their number is fixed.

MD: Bad idea. This fixing of the number “guarantees” the process will be deflationary. In a “real” process, inflation (deflation) is perpetually zero.

HN: Therefore, rather than using cryptocurrency units as reward, the forgers receive transaction fees as rewards. In a few cases, new currency units can be created by inflating the coin supply, and forgers can be rewarded with new currency units created as rewards, rather than transaction fees.

MD: What are these cases? If this can be done, how can they say the number is fixed? Also notice that their process seems to “require” that the creators of the money be “rewarded”. This is also taken from our flawed (corrupt) existing system. They implement a process of elites with power and privilege and ability to demand tribute … just like our current flawed system.

HN: In order to validate transactions and create blocks, a forger must first put their own coins at ‘stake’. Think of this as their holdings being held in an escrow account: if they validate a fraudulent transaction, they lose their holdings, as well as their rights to participate as a forger in the future.

MD: So they take their fake wealth and risk it … like putting it up as collateral. This is also from our existing flawed system. The capitalists take just two years to reclaim their stake (they collect 40%/year interest which doubles in two years). After that, they are forever playing with OPM (Other People’s Money) and risk nothing themselves at all.  A “proper” MOE process uses perfect “transparency” and “interest collection according to propensity to default” to keep the players honest and provide negative feedback for stability. In a proper process, these deadbeats can pay back their defaults and return to good standing.

HN: Once the forger puts their stake up, they can partake in the forging process, and because they have staked their own money, they are in theory now incentivized to validate the right transactions.

MD: Myth in the open. Putting up a stake does not mean putting up their own money. They’ve gotten back their own money through deflation very quickly.

HN: This system does not provide a way to handle the initial distribution of coins at the founding phase of the cryptocurrency, so cryptocurrencies which use this system either begin with an ICO and sell their pre-mined coins, or begin with the proof of work system, and switch over to the proof of stake system later.

MD: Now they’re borrowing from the corporate model where a group can create a vision, sell a little less than half to suckers (in the form of stocks), hype the vision, pull out their stake but leave themselves in control, and bingo … you have another form of elite gaming of the system. And again, how do they switch systems later.?This sounds like they’re destroying the money and then using it to buy gold. Our current MOE manipulators call this the “business cycle”. It’s their “farming operation”.

HN: Cyptocurrencies that currently run the proof of stake system are BlackCoin, Lisk, Nxt and Peercoin, among others.
Proof of work mining versus proof of stake forging.
Block Selection Methods
For a proof of stake method to work effectively, there needs to be a way to select which user gets to forge the next valid block in the blockchain.

MD: There must be privileged users. In our present corrupt system we call them bankers (and sometimes governments) and they get 10x leverage over the rest of us.

HN: Selecting the forger by the size of their account balance alone would result in a permanent advantage for the richer forgers who decide to stake more of their cryptocurrency units. To counter this problem, several unique methods of selection have been created. The most popular of these methods are the ‘Randomized Block Selection’ and the ‘Coin Age Based Selection’ methods.

MD: This is characteristic of processes invented by very smart people with very good memories. Rather than seeing the rudimentary flaws in what they are doing, scrapping it, and starting over with a better concept, they run into obvious flaws we less smart people see immediately, and come up with more and more complicated workarounds … and the process soon stops because no one understands it.

HN: Randomized block selection

In the randomized block selection method of selection, a formula which looks for the user with the combination of the lowest hash value and the size of their stake, is used to select the next forger. Since the size of the stakes are public, each node is usually able to predict which user will be selected to forge the next block. Nxt and BlackCoin are two proof of work cryptocurrencies that use the randomized block selection method.

MD: This looks like an open invitation to corruption and manipulation. And when you have a “randomizing” process, the pseudo-random number generator must be open and fixed. Everyone must use the same process. The same random seed must yield the same next random number. This is problematic for obvious reasons.

HN: Coin Age based selection

The coin age based system selects the next forger based on the ‘coin age’ of the stake the potential forger has put up. Coin age is calculated by multiplying the number of days the cryptocurrency coins have been held as stake by the number of coins that are being staked.

MD: Look how long Bitcoin ran before people started to pay attention  … it was several years. During that time they were giving coins away just to make it look like there was activity. Mining costs were trivial and the supply grew very quickly with the demand not growing at all. Now that it is starting to catch on (the hook is getting set), these early worthless “coins” own the process. What’s not to like about that? Duh? A Ponzi scheme with no Ponzi.

HN: Coins must have been held for a minimum of 30 days before they can compete for a block.

MD: This is building a time constant into the process … and is open for manipulation. A proper MOE process has no openings for manipulation at all.

HN: Users who have staked older and larger sets of coins have a greater chance of being assigned to forge the next block. Once a user has forged a block, their coin age is reset to zero and then they must wait at least 30 days again before they can sign another block
.
MD: How is this done? Does this mean the “timestamps” for the coins … used for determining age … can be manipulated too? What’s not to like?

HN: The user is assigned to forge the next block within a maximum period of 90 days, this prevents users with very old and large stakes from dominating the blockchain thereby making the network more secure.

MD: Another knob to manipulate … another opening for fraud and corruption … by regulators.

HN: Because a forger’s chance of success goes up the longer they fail to create a block, forgers can expect to create blocks more regularly. This mechanism promotes a healthy, decentralized forging community.

MD: This is classic complication delivering fairness. Hint people: Fairness is not complicated. But it does go against something that is current flawed wisdom … wisdom that says centralization is good. This says centralization is “not” good. So let’s apply that wisdom … iterative secession. BTW: With a “proper” MOE process, there can be any number of independent processes as long as they all deliver the same transparency and follow the same simple rule (DEFAULT perpetually equals INTEREST collected). No system can be better in any way so all competing systems are equal in performance to the traders using it.

HN: Peercoin is a proof-of-stake system based cryptocurrency which uses the coin age selection process combined with the randomized selection method. Peercoin’s developers claim that this makes a malicious attack on the network more difficult, since purchasing more than half of the coins is likely costlier than acquiring 51% of proof-of-work hashing power.

MD: Notice how all these “complicated” processes have “developers” making “claims” and solving open flaws in other complicated processes … such flaws being prone to “malicious attacks” … opened by their complexity.

HN: Most proof of stake coins that pay a reward in the form of a transaction fee for verifying transactions and creating new blocks, set a target interest rate which users can expect to earn from staking their coins.

MD: Another knob (interest) that a proper MOE process knows should never exist but rather should be an automatic negative feedback mechanism with no opening for intervention. A proper MOE process has no monetary policy. Rather, it precludes it totally.

HN: In the case of cryptocurrencies where forgers create new coins, this rate also becomes the maximum rate at which the currency supply is inflated over time.

MD: “Maximum rate”? For inflation? Over time? What a joke. They clearly have no understanding of what money is. Hint: Don’t try to create a money process without know what money is. Hint: Money is “an in-process promise to complete a trade over time and space and is “always” and only created by traders”.

HN: Proof of stake systems are more environmentally friendly and efficient, as the electricity and hardware costs are much lower than the costs associated with mining in a proof of work system.

MD: A “proper” MOE process is “perfectly” environmentally friendly and efficient. It costs nothing to create and destroy money. There is no “profit” to be made in the process anywhere. The total cost is always borne by the traders and is trivial to the size of their trades. Ideally, it is absorbed as an implicit default and is paid through interest collections on deadbeat traders. Responsible traders pay nothing at all.

HN: A greater number of people are encouraged to run nodes and get involved because it is easy and affordable to participate in this system; this results in more decentralization.

MD: In a proper MOE process, the only incentive to become a node is to decrease latency … and that is a huge incentive. It’s like a communication system with no backbone. Rather it is a mesh system where all nodes make up the connection path. This would be an obvious improvement over the current (easily manipulated) internet process. Can you say “network neutrality?”

HN: This is only a general guide to the proof of stake system. Each cryptocurrency issuer will most likely customize this system with a unique set of rules and provisions of their own as they issue their currency or switch over from the proof of work system.

MD: But the different monies  themselves must be indistinguishable to the “users” (as opposed to the “creators”) of the money. And they must be non-counterfeit able.

HN: Additionally, this is a rapidly evolving industry, and apart from proof of work and proof of stake, there are currently several other systems and methodologies of transaction verification and block creation being tested and experimented with.

MD: All equally complicated and demented I’m sure.
