User Guide
PBS(Proposer-Builder Separation) framework offers several advantages for SimpleChain2.0 users:
- Users are less likely to have their transactions front-run or sandwiched.
- Increased competition among block builders can lead to more efficient markets and potentially lower gas prices.
- Enhanced transaction privacy: Users' transactions are exposed to fewer parties before being included in a block.
- Faster transaction processing: More efficient block construction can lead to quicker transaction confirmations.
For Retail Traders
When you trade on a decentralized exchange (DEX), you risk being targeted by bots that can front-run your trades, meaning they see your transaction in the public mempool and execute a similar trade first, profiting from the price change you were going to cause. This can result in you getting a worse price or even losing money. Private RPCs offer a solution to this problem. They route your transactions through a private mempool(Provided by builders), hiding them from bots. This means your trades are less likely to be front-run, and you're more likely to get the price you expect.
Some DEX protocols or builder providers are keen to provide free protection features, and the average transaction confirmation time is around 4-5 seconds, and it may fluctuate according to the network conditions.
Builder Proxies
The builder proxies act as a transaction broadcaster for builders. Instead of users' transactions being limited to a smaller set of pre-registered validators or specific builders, the proxies take each submitted transaction and broadcasts it to all registered builders across the network. This broader dissemination benefits users by significantly increasing the chances of their transaction being picked up by a builder and included in the next block, leading to faster transaction confirmation times. Furthermore, the increased competition among builders, who now have access to a larger pool of transactions, can potentially result in more efficient block construction and, indirectly, potentially lower transaction fees and improved censorship resistance for users.
Wallets with Manual MEV Protection:
Several wallets now offer built-in protection against malicious MEV (Miner Extractable Value) attacks, enhancing the security and fairness of users' transactions. This protection is often available as a feature that users can manually enable during their swap or trading activities.
- Private Transaction Relays: These relays hide transaction details from malicious actors, preventing them from front-running or sandwich attacking the user's trade.
- Specialized Builders: Some wallets utilize builders that prioritize user protection and fair ordering of transactions, minimizing the potential for MEV exploitation.
