Guide to the block explorer

This is beginners guide to understanding the different ways the block explorer can be used.

Search bar : When looking for a specific transaction, you can enter details here such as the block height, block hash or transaction hash.

Server time : the server time is the date and time in Co-ordinated Universal Time (UTC).

Network difficulty : this shows the current difficulty the blockchain is running at. Difficulty is the average number of miner hashing attempts required to find a valid block hash at the current time.

Hash rate : the estimated amount of power being put out by the miners, ie how many hash attempts are being made per second.

Median block size limit : The maximum allowed block size at any given time is twice the MBSL. The MBSL currently has a fixed lower bound of ~150kB, but takes the value of the median of the last 100 blocks should it exceed this size.

Transaction pool : the transaction pool/mempool contains all the transactions currently waiting to be assigned a block, including transactions that have been orphaned.

Transactions in the last block : This shows all the transactions that were in the most recent block, their size, associated fees and how many inputs/outputs they are composed of.

Tx hash : the transaction (Tx) hash is the unique identifier of the transaction.

Tx public key : is a ‘stealth address’ for funds, meaning that only the beneficiary can spend the funds located there with a one time private key and other outside observers of the blockchain can’t identify the Electroneum public address associated with the funds such to reveal the identity of the owner.

Block Timestamp : It equals to the date shown by the “second” (UTC) timestamp

Timestamp UTC : this is a translation of the first timestamp, but in human comprehensive way.

Age : the age of the transaction in seconds, minutes, hours, days, years running right to left.

Block : these show the block that your transaction has been assigned to. You can click on the block number and see more information, such as all the other transactions in the block, the size of the block, etc.

Fee : this shows the fee that was paid when the transaction was sent which is paid to the miner of the block.

Tx size : the size of the transaction (Tx) in kilo bytes (KB)

Tx version : the version of the transaction (Tx)

No of confirmations : the number of blocks that have gone by since your transaction entered the chain.

RingCT/type : this is called a ring signature, which is used for privacy. During our fork in May, we removed that so our transaction size would be smaller, allowing more transactions to fit in one block.

Extra : extra field of arbitrary data

Outputs : this can give a different number of outputs, depending on the size of the transaction. This is used as a privacy tactic, so that you cannot see how much has been sent.

Decode output : you can use this to check which of the outputs relates to the transactions. For example, only 3 out of 5 of the outputs would be “true”, so they would make up the actual amount of Electroneum (ETN) that belong to you.

Prove sending : use this to prove to someone that you have sent them Electroneum in this transaction and that certain outputs on the blockchain belong to them

Inputs : these are made up of individual transactions originally sent to the user, which are now being sent out. (i.e. if the user is sending 30 ETN, but it was sent to them in two transactions of 10 ETN and two transactions of 5 ETN, in the input section you will see those four transactions that created the 30 ETN originally)


This is only for ETN or you can use it for any Crypto?

This guide is based on the ETN blockexplorer.
