No. Bloom filters are probabilistic data structures, they don't give strong guarantees.
If all you want to do is ensure that a transaction is "valid for inclusion" then you can just check the user's nonce in state and see if the nonce in the transaction you have is 1 higher (more than 1 higher may eventually become valid, but aren't yet valid).

@qsmen
Thank you, I see almost. An address or an account will have the nonce field for comparison?
Micah Zoltu
@MicahZoltu
If you have access to state for the blockchain as of a particular block, you can get the accounts current nonce, and compare that against the transaction you have to determine validity.
qsmen
@qsmen
nonce get increased 1 higher each transaction, not random
Micah Zoltu
@MicahZoltu
Yes, exactly.
Every transaction from an account increments the account nonce by exactly 1, and no nonce can be used twice, and you cannot skip a nonce.
qsmen
@qsmen
ok,ok. thank you
Micah Zoltu
@MicahZoltu
So an account's first transaction is nonce 0, second is nonce 1, third is nonce 2, etc.
qsmen
@qsmen
i see,
Micah Zoltu
@MicahZoltu
So if you lookup an accounts nonce and get back 1, that means the next valid transaction from this account MUST have a nonce of 1.
qsmen
@qsmen
ok, I see. a simple way to prevent replay attack under the condition the bit size of nonce is long enough

heyo can anybody tell me if eth2 is based on the casper paper?
is there any formal paper on the maths behind eth2?

Guys I have been reading about EIP 1559 and the replacement of gas fee with a base fee. I have a question - How does EIP 1559 deal with the halting problem? Running out of gas whilst processing a transaction currently solves the problem of infinite loops as I understand it. But if the base fee model doesn't have gas then how is the halting problem mitigated?

Hello everyone I am Phd student and am looking for some answers could someone help
I wanted to know if its possible to have a blockchain based program that works with traditional currency while having a wallet that pays the gas?

hi everyone, I have used tender mint consensus engine. It is proof of stake and uses the weighted round-robin algorithm to select the proposer. Is it same in Ethereumโ€™s Casper design also?

Hi, does anyone know how we can manipulate the value of msg.value when testing Solidity contracts on the remix IDE? msg.value is always set to 0 and I can't seem to change this on testing
Marius van der Wijden
@MariusVanDerWijden
On the deploy and run tab, there's a value field (below gas limit) that you can use to specify msg.value

In casper, do voters validators vote on every block or only every 100 blocks?

Hello all, not sure if this is the right place to ask the question. Sorry if it is not.
I have deployed my contract to Rinkeby and I can see my deployed address in rinkeby.etherscan.io but I am not able to access that from remix tool. I could connect to my account using the Injected Web3 environment and see my account get populated, but I do not see any deployed contracts in the bottom. I have tried both https and http versions of remix tool, but not luck. Any help would be highly appreciated.

Hi all. Suppose I wanted to create a messaging service that uses Ethereum as it's backend. How could I create a free-tier for the service when there are GAS fees to pay for each transaction (message from sender to recipient)? Is there an established or emerging business pattern to negate the fees somehow? Is it possible to pay the fees by generating the eth in other ways?

hello, everyone.
how are you?
I am new in this group.
what is mission of this group?
Michelle Antonello
@Seagat2011

Hello Ethereum research group I have a personal request: I would like The Ethereum group to again fork the project to focus on a new Locked token which cannot be sold but only bought or transferred into another locked wallet.

This would eliminate downside volatility on the exchanges while allowing the wallet to be collateralized possibly up to 85%+ by banks! all while maintaining the ability to create new tokens and new wallets on the exchange without diluting the Value of ones ownership

Please consider this

I am getting above error sometimes.
But I ignored them before realtime.
once I add realtime code, it is showing error like that.
