Output: In Solana, data/state is stored in accounts rather than in programs.


Input: What is the purpose of instruction data in a program?

Output: The instruction data in a program is used to convey what operations the program should perform and any additional information those operations may need.


Input: How is information encoded into the instruction data byte array?

Output: Programs are free to specify how information is encoded into the instruction data byte array. The choice of encoding should consider the overhead of decoding, as that step is performed by the program on-chain.


Input: Can a transaction contain instructions in any order?

Output: Yes, a transaction can contain instructions in any order. This means a malicious user could craft transactions that may pose instructions in an order that the program has not been protected against.

Output: The "getTransaction" method returns transaction details for a confirmed transaction.


Input: What does the "getFeeCalculator" method return?

Output: The "getFeeCalculator" method returns the fee calculator associated with the query blockhash, or null if the blockhash has expired.


Input: How are accounts in the program similar to files in operating systems?

Output: Accounts in the program are similar to files in operating systems because they both hold arbitrary data that persists beyond the lifetime of a program.


Input: What is the purpose of metadata in an account?

Output: The metadata in an account includes information about who is allowed to access the data and how, allowing the runtime to make authority decisions.


Input: How are read-only accounts treated in transactions?

Output: Read-only accounts can be read concurrently by multiple programs, but if a program attempts to modify a read-only account, the transaction is rejected by the runtime.


Input: How can an account be marked as executable?

Output: An account can be marked as executable during a successful program deployment process by the loader that owns the account.


Input: What happens when an instruction references an account that hasn't been previously created?

Output: When an instruction references an account that hasn't been previously created, the program will be passed an account with no data and zero lamports that is owned by the system program.


Input: What is the importance of checking an account's validity in a program?

Output: Checking an account's validity ensures that the program is interacting with the correct and owned accounts, preventing unauthorized access or manipulation.


Input: How does the Solana SDK check the validity of a sysvar account during deserialization?

Output: The Solana SDK checks the validity of a sysvar account during deserialization by verifying its address and owner, ensuring it is a real and valid sysvar account.

Input: Is it necessary to run solana-watchtower on a separate server from my validator?

Output: It is recommended to run solana-watchtower on a separate server from your validator to avoid situations where both processes stop simultaneously, such as during power outages or system restarts.


Input: How can I set up watchtower notifications on Telegram?

Output: To set up watchtower notifications on Telegram, you need to create a bot using @BotFather, obtain an HTTP API token and chat ID, and then set the corresponding environment variables for your bot.

Output: If the rebroadcast queue size is greater than 10,000 transactions, newly submitted transactions are dropped.


Input: How does Solana's leader schedule differ from other gossip protocols like Ethereum?

Output: Solana's leader schedule is known in advance of every epoch and transactions are broadcasted directly to the current and next leaders, unlike Ethereum which propagates transactions randomly across the network.


Input: What are some scenarios in which a transaction can be unintentionally dropped from the network?

Output: Some scenarios include UDP packet loss, overwhelming validators, issues with RPC pools, and temporary network forks.


Input: What is the primary tool available for developers to submit transactions?

Output: The primary tool available for developers to submit transactions is the sendTransaction RPC method.

Input: How can developers manually control the retry process when developing their own rebroadcasting logic?

Output: Developers can manually control the retry process by taking advantage of sendTransaction's maxRetries parameter.


Input: What is a common pattern for manually retrying transactions?

Output: A common pattern for manually retrying transactions involves temporarily storing the lastValidBlockHeight from getLatestBlockhash and then manually retrying the transaction at an appropriate interval.


Input: In times of network congestion, what is advantageous to do with maxRetries?

Output: In times of network congestion, it is advantageous to set maxRetries to 0 and manually rebroadcast via a custom algorithm.


Input: What is the purpose of this guide?
