While this is a given, it is advisable to wait for six additional blocks to be mined and added on top of the block where your transaction was entered. When this happens, your transaction is said to be finalized and irreversible. Remember that the blockchain is a chain of blocks containing transaction details.

In a situation where validators add two blocks to the chain at the exact same time, the blockchain will momentarily split into two. Going forward, the chain that subsequent validators add their newly created blocks to will eventually become valid, while the second block will become orphaned that is, not accepted into the main chain. Simply put, the longest chain is widely regarded as the main chain or the most valid chain.

By checking the status of your transaction, you can determine whether your transaction is pending or successful. You can also confirm the number of blocks that have been created since your transaction was added to the blockchain. Get to know the cost of transacting on Ethereum Ethereum participants must pay to use the network in order to transfer value and create or deploy a smart contract.

However, unlike the fixed fee structure we are used to with conventional payment systems, the amount paid to process each transaction largely depends on the number of participants looking to execute transactions at any given time. If the demand is high, expect the transaction fee to rise in cost. The opposite is the case when demand is low. That said, checking your transaction details helps keep track of the cost of using the Ethereum network. In addition to this, you can determine when your gas fee is not enough to trigger the confirmation process.

This is paramount, knowing fully well that miners tend to prioritize transactions that will fetch them the highest reward.

A not so trivial example seems to track token balance of an address. I thought about the following example: Having nothing but an address and a full node, how can I get all the transactions made by this address, including token transfers and amount of transferred tokens? I understand that tokens are not more than mapped addresses in a smart contract correct me if I'm wrong and so my first thought was to just read the balanceOf method assuming its ERC20 standard.

But that would just give me the current amount, not all the past transactions. So what gives me some headaches now is trying to "connect" like wire the concept in my brain addresses and smart contracts. On gas As mentioned, transactions cost gas to execute.

Simple transfer transactions require units of Gas. Diagram adapted from Ethereum EVM illustrated Any gas not used in a transaction is refunded to the user account. Transaction lifecycle Once the transaction has been submitted the following happens: Once you send a transaction, cryptography generates a transaction hash: 0x97d99bca21b12ccd4ff1dffdff The transaction is then broadcast to the network and included in a pool with lots of other transactions.

A validator must pick your transaction and include it in a block in order to verify the transaction and consider it "successful". As time passes the block containing your transaction will be upgraded to "justified" then "finalized". These upgrades make it much more certain that your transaction was successful and will never be altered. Once a block is "finalized" it could only ever be changed by an attack that would cost many billions of dollars.

A visual demo Watch Austin walk you through transactions, gas, and mining. Typed Transaction Envelope Ethereum originally had one format for transactions. Each transaction contained a nonce, gas price, gas limit, to address, value, data, v, r, and s.

These fields are RLP-encoded, to look something like this: RLP [nonce, gasPrice, gasLimit, to, value, data, v, r, s] Ethereum has evolved to support multiple types of transactions to allow for new features such as access lists and EIP to be implemented without affecting legacy transaction formats. EIP Typed Transaction Envelope defines a transaction type that is an envelope for future transaction types. EIP is a new generalised envelope for typed transactions. In the new standard, transactions are interpreted as: TransactionType TransactionPayload Where the fields are defined as: TransactionType - a number between 0 and 0x7f, for a total of possible transaction types.

TransactionPayload - an arbitrary byte array defined by the transaction type. Further reading Know of a community resource that helped you?
