It was only today that I realized that Ethereum is over 10 years old, that it has become (or will become) a movie!

It's really impressive that, after all this time, no one realizes an obvious fact: Smart contracts are useless.

In other words, they are just a factory of useless tokens. Ah, ok, they also serve as mathematical proof that you paid for a thing that can be copied for free.

You can get mathematical proof of how stupid you are.

It all started with the bitcoin scripting language, a mistake by Satoshi that Vitalik raised to the thousandth power.

That in all this time there has been nothing useful built with smart contracts is obvious, but nowadays it is necessary to state the obvious.

Re: New coin ideia - reveal the private key - Democracycoin?
by
soldate
on 25/09/2024, 17:04:53 UTC
yeah you are right.. i think "my ideia" is actually a "permissioned blockchain".

in fact 100% real decentralization is impossible, its always be more or less decentralization.

bitcoin has a fame of being descentralized, but its in fact very few decentralized. few developers can really understand the code, few miners (very big miners)..

people should keep looking for solutions, but i guess greed has already ended this search

This does already exist, in many variants. It's called a "permissioned blockchain". One example is the Bitcoin "sidechain" Liquid. As all nodes are known, if one node misbehaves, he can be excluded from the list.

A slightly more decentralized variant is DPoS or delegated Proof of Stake, where stakers (coin owners) vote a subset of validators.

However, 50% for a "vote" has been proven too low for these algorithms. Most use two thirds (66%), which is also the threshold for PBFT, the technical base of Ethereum since the Merge.

Double spending is also not fixed by "revealing a private key". Normally in double spends two subsets of nodes are tricked, one (with the victim(s) amoung them) into believing that a transaction is valid, the other that it never existed or that it was invalid.

In a permissioned blockchain however this is normally not possible. But all nodes have to trust each other. So I see no advantage of your "reveal private key" approach to the traditional Bitcoin transaction format, where you don't reveal a private key but sign a transaction.

I think maybe you are oversimplifying this a little too much.  The system you described seems to have some big holes that could make it pretty easy to hack.  For instance, having a set list of nodes that everything runs through leaves a pretty obvious weak spot.  If someone managed to mess with enough of those nodes, they could maybe bring the whole system down and  or make fake nodes to rig the voting system.

Whats to stop someone from creating hundreds or thousands of fake nodes even on a single computer?


the urls/nodes will be written in the source code. more nodes, more decentralized.

Suppose:

a huge (100? 1000? 10k?) list of urls/nodes in the source code

many coins, each coin with a different id and owner (public key).

the owner of the coin (public key) wants to send it to someone else.

it signs a transaction with the coin id and the public key of the new owner and notifies all the urls in the list.

then it counts the 'ok' answers.

If it gets 50% + 1 'oks', it sends the private key to the nodes.

Transaction complete. That coin has a new owner.

Since the private key has been revealed, there is no way to double spend.

If the transaction/coin does not receive 50% + 1 of the votes, in pratice it will be "burned" (nobody will not be able to spend it).

While the majority of the nodes/ips are honest, the coin is safe.

"The proof-of-work also solves the problem of determining representation in majority decision
making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone
able to allocate many IPs.
Proof-of-work is essentially one-CPU-one-vote. The majority
decision is represented by the longest chain, which has the greatest proof-of-work effort invested
in it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the
fastest and outpace any competing chains." - Satoshi Nakamoto

We just need a FIXED long list of nodes/urls.

If we choose 300 nodes, we already has a propaganda for the coin  Grin

Bitcoin é "dinheiro honesto" só no sentido da pessoa se sentir bem, fingir que acredita, mas o troço já era.

Pra substituir tem que ter alguma paridade com a moeda estatal, transação grátis e instantânea, etc.

Estou tentando, vamos ver se aparece alguém sonhando igual e começamos uma moeda honesta.

Entendi. Você então quer "dinheiro honesto" dos outros, pra sua moeda tem paridade com a moeda estatal?

Muito honesto  Cheesy

Boa sorte.

Transação grátis e instantânea não faz sentido, só se você fizer tudo do computador da sua casa.  E mesmo assim não seria gratos. Quem pagaria os servidores para manter tudo?

Veja bem, não é pra levar tudo ao pé da letra. Os servidores precisam ser pagos, mas o custo é mínimo. Pode ser com impressão monetária ou com uma pequena taxa de transação.

Dinheiro honesto é dinheiro vigiado, transparente e com opção de saída. Mas o principal é as pessoas quererem isso, hoje só se quer ficar rico sem fazer nada, a verdade é essa.

Não falo em paridade fixa com o dinheiro estatal, mas alguma estabilidade tem que ter, senão o comércio não aceitará a moeda.

MAs falando sério, o bitcoin não tem com dar certo. Pode ter feito muitos ricos, pode até ser um "sucesso" mundial, mas não atngiu o objetivo de tirar o dinheiro do estado, de fazer as moedas competirem no mercado como qualquer produto.

Todo mundo quer só comprar barato e vender caro, quer dólares, a mudança real, criar um dinheiro honesto, já ninguém nem fala mais sobre isso.

A alternativa ao DREX é o bitcoin.

Essa altcoin, drecs, é apenas uma alternativa para fazer o criador dela acumular mais drex ou mais bitcoin.

Essa tal de Drecs é do mesmo criador da moeda CHOPPcoin, aquela que seria aceita em todos os bares e locais similares do Brasil. Parece que a CHOPPcoin não deu resultado e o desenvolvedor está tentando um projeto novo. Quem sabe esse "novo projeto" não vá adiante. Eu não apostaria, mas tem maluco para tudo.

Bitcoin block height now is about 770,500

So, we need now:

1) "reset" bitcoin blockchain. i mean:
1.1) Understand how to generate a "new genesis" block using the 770,500 block.
1.2) Put utxo (of the 770,500 block chain) directly in the source-code or in a file to be loaded when daemon starts.

and see if it works (keep receving bitcoin blocks).

then

2) change to RandomX. i mean:
2.1) understand how to call c++ code (randomx) from golang.
2.2) choose some height (like 770,611) to use the new algo
2.3) mine a new block and see if works.

[ANN] Bitcoin 3x - Back to the future
by
soldate
on 04/01/2023, 16:12:27 UTC
Words: Decentralization, money primarily as a medium of exchange, simplicity and guarantee of honesty.

Bitcoin: merits and demerits.

Bitcoin is (was) the biggest attempt to create a state-free money.

This must be considered, so one of the principles is that changes should not harm current participants.

What we propose is a fork on bitcoin, creating a new currency from the current one, keeping people's balance and without creating money out of thin air.

What is Bitcoin supposed to be? Decentralized money.

What is Bitcoin? Greed. A centralized betting game, dreaming of to be a new gold. Bitgold.

How can we get it back on track to be an out-of-state money?

We have to solve 3 problems:

Centralization. The best fight against this issue was given by Monero, with the RandomX algorithm. Keeping the currency decentralized is not just desirable, it's all that matters.

Complexity. We need to return to the Bitcoin White-Paper, doing just the basics and doing it well, in order to attract a lot of developers who understand the source code and able to correct the path if they get lost again, maintaining decentralization. No more smart-contracts, which have proven to be just a useless token factory.

Adoption by commerce. In the long term, the ideal is to have a certain stability with dollar price, otherwise the commerce will not accept it and we will be one more stupid attempt to be invisible gold.

How to make this thing works? 3 steps:

Fork the project, setting a date (or block height) for the RandomX be the new mining algorithm. Also, we can recreate the genesis block (with the UTXO) from the chosen block, in such a way as to speed up the blockchain download, throwing away the old data.

Step 1 does not solve the problem of infinite data growth, but it gives us time to solve it, while making it easier for new miners to enter.

In the long term, think of a solution to get more price stability with dollar. Maybe we can increase the amount of it in proportion to what each one has. Thus, the gain for the user will be the same at the same time that it facilitates adoption by commerce. In another words, inflation will work in your favor.

Important questions before project starts:

The current bitcoin source code is very complex. We can start from it or start from other simpler project that has implemented a Bitcoin full node.

Possibilities: C++ project (current): https://github.com/bitcoin/bitcoin
Rust Project: https://github.com/paritytech/parity-bitcoin
Golang Project: https://github.com/btcsuite/btcd
Project C: https://github.com/chjj/mako

Of all of them, it seems to me that the best solution thinking in more developers, is to start with the Go version.

Once the project has really started, that is, with the first block incompatible with bitcoin be mined, we will start preparing the code cleanup.

At another future date, we will remove the scripting language, segwit and anything else that makes the code bigger and complex.

Once that another fork takes place, we finally clean up the source code, making it 1% of the size and easily understandable by any developer.

After that, we started discussions on how we can achieve price stabilization, without harming users, keeping the currency strong and facilitating adoption by commerce.

Let's do it?
