Polygon Is Bringing EIP-1559 Upgrades to Its Network With a Testnet Release
https://blog.polygon.technology/polygon-is-bringing-eip-1559-upgrades-to-its-network-with-a-testnet-release/
"Polygon is taking steps to bring this much-requested upgrade to our network. It goes live on the Mumbai testnet on Dec. 14, at 8 a.m. UTC.
Polygon’s MATIC has a fixed supply of 10 billion, so any reduction in the number of available tokens will have a deflationary effect. We took Ethereum’s experience since the upgrade as the baseline to simulate the potential impact on MATIC’s total supply. The analysis, which can be seen here, suggests that annualized burn would represent 0.27% of the total MATIC supply."

I constantly hear what is better zk rollups than an optimistic. But who is the best of zk rollups? @Dareal_sisyphe has an opinion on this question.

Protocol zkSync
https://blog.matter-labs.io/funding-ea89c1fa731e
"zkSync is a ZK rollup, a Layer-2 scaling solution that preserves the security properties of the underlying blockchain by leveraging the latest generation of succinct zero-knowledge proofs."

exchange
https://trade.zigzag.exchange

Works with ledger. Commission ~ $ 1 per transaction

https://zksync.io/faq/tokens.html#listing-a-token
"Transfers in zkSync support "gasless meta-transactions": users pay transaction fees in the tokens being transferred. Thus, for example, if you want to transfer DAI stable-coin, there is no need for you to own ETH or any other tokens. Just pay your fees in a fraction of DAI.

For tokens without a liquid market price, fees are paid in a different token."

Is the $6B locked in L2 secure?

"Today L2BEAT lists nineteen Layer 2 solutions live on Ethereum Mainnet. To fully grasp the security of all the $6B locked in those systems one would need to analyse each and every one of them individually."

Heard this l2 solution Arbitrum months ago but never tried it yet. Im still trying to understand how this work on top of eth, Is this l2 already supported by top CEX exchanges like Binance? I know its already live in Uniswap v3, but according to what I search you have to bridge your eth into arbitrum chain to be able to use but Im thinking it can cost you huge transaction fees on this process?   

Personally I switched to layers 2 and alternative chains long time ago as Ethereum's transaction fees are unbearable. Arbitrum and Optimism are  Layer-2 solutions running on top of the Ethereum blockchain. They combine several transactions and remove some of the load from the main network, which allows you to reduce the transaction fee and increase its speed.

Polygon Just Gave Us a $1 Million Early Birthday Present!
"QuickSwap will be one year old this month!
To celebrate, and help bootstrap some additional liquidity onto the DEX, Polygon has provided us with $1 million in $MATIC to offer dual farming rewards for select pairs — similar to the campaign they funded that helped Aave grow massively on Polygon.
We will match and exceed all funds provided by Polygon in $QUICK rewards over the coming months
Stay tuned for more information about all of our upcoming birthday celebrations"

Optimism
https://vitalik.ca/general/2021/11/16/retro1.html

"Conclusions
Generally, I think Round 1 of Optimism retro funding has been a success. Many interesting and valuable projects were funded, there was quite a bit of discussion, and all of this despite it only being the first round.

There are a number of ideas that could be introduced or experimented with in subsequent rounds:"

"Updated weekly, the score will initially be comprised of the following metrics:

Two-week engagement: How active has a user been in the last two weeks
10-week retention: How many weeks in the last 10 weeks has the user engaged with Polygon
Net inflows: Has the user deposited or withdrawn more funds into Polygon in the last two weeks. This is a binary metric, and the total amount is not a factor"

Aurora sidechain is a better alternative. It is 100% trustless and compatible with Ethereum. It uses ETH natively to pay for gas and DApps work on Aurora without modification. Aurora uses sharding, which means it can theoretically process infinite TPS. There is no long withdrawal time for Aurora like most L2s. Transactions on Aurora are less than a penny, that's cheaper than L2s.

The problem is always a high "gwei", this is the reason for the emergence of new ones besides being economical, plus the network is fast, and easy, once they have this trust it will repeat itself, by increasing the gwei slowly.

As far as I understand, the Arbitrum network does not have a native coin, so it looks like an L2 scaling technology for Ethereum. Its main advantage is that the Uniswap decentralized exchange supports this solution, so traders can use different farming and harvesting protocols and pay low transaction fees. On the other hand, the downside is that people cannot invest in Arbitrum as a promising cryptocurrency.

Polygon seems to me the better solution for scaling and acting as a bridge, although I admit that in general, PoS networks are too centralized. In fact, Polygon has a native coin, so I want to buy some MATIC as a middle-term investment.

Even now, asset transfers on the Polygon network are very cheap.

https://forum.matic.network/t/increasing-min-gas-price-to-30gwei/2531
Increasing Min Gas Price to 30Gwei
"To reduce the number of spam txns in the network, we are increasing the minimum gas price to 30Gwei from the current (default) value of 1Gwei. It’s recommended to increase the gas price to 30 gwei, but validators are free to chose their own min gas price."

another reason why to go with Arbitrum is the possibility of an airdrop to their users, we've seen airdrops like that this last few years, it is a good interface and even though i think that optimism is a bit better, I am using Arbitru and it is because of the possible airdrop and the small differences between the two of them.

It is now impossible to work in the 1st level of Ethereum. Commissions can grow at any time.

how sure if there is a turmoil it will not be the same as the ETH gwee incident, the network path causes the price to be high, in the past when they used ERC 2.0 they also did the same thing but it couldn't be dammed by the market pressure. alternatives are temporary but BSC, Polytron and ECO have so far started to balance those prices. I hope they can keep it up in the future.

The cost of TVL in the Ethereum solution L2 Arbitrum increased by more than 3263% over the week and reached a record $2.2 billion.

On September 15, a 45-minute failure occurred in the work of the Ethereum solution of the second level of Arbitrum due to an error in the Sequencer contract. During this time, the network did not process transactions. The developers reassured users that their funds are safe. https://medium.com/offchainlabs/arbitrum-one-outage-report-d365b24d49c

The commissions on Ethereum are very large, I advise you to start understanding Level 2 solutions.
