Additional columns and indexes were added over time to the original SQL design. The size of the database is now almost GB, resulting in very high server memory costs. Such costs, ongoing maintenance and limited interest in the project has caused a re-evaluation of the overall design and business model.
Compute facilities will no longer be available past the above date. Access to saved snippets will be available for a limited period after this date. Please locally save any snippets you may have. Blockbin has recently added some additional columns and indexes to the SQL schema.
Your Python code now has access to even more data from the Bitcoin blockchain. This may offer some additional insights into the operations and growth of the network. Let us take a look at block size. We can construct a more complex query here. Note - older coins are typically prioritized and can influence the overall required fee, even qualifying for a 'free' transaction occasionally. There are also a number of other conditions that affect transaction fees. Firstly, let us determine how many transactions have no fees at all.
Instead of charting overall block sizes, we will sum all transaction sizes within each block that contain no fees. An average of 7KB per block contain transactions with no fees approximately 4 transactions per block. These will either be old coins moving, transactions without fees, or the coinbase transaction. For simplicity and argument's sake, let us conclude that all transactions should pay a fee. We will now sum all transaction sizes within each block, filtering out transactions that do not include a minimum fee per kilobyte 10, satoshis per 1, bytes.
An average of KB per block. Note a huge difference compared to the first chart. This is good, however, as it means participants are paying fees!
The current 'fee' of 10, satoshis approximately 4c USD per transaction or KB becomes very expensive for those looking to spam the network. Should spam, however, determine the cost of a transaction?
Let us go further with this.. The 'halvening' is close approaching. Sometime in July of this year block height , the block reward will drop from 25 BTC to Miners operate in the physical world and are subject to real-world costs.
This drop has probably already been priced-in to some extent by the major miners and their projected earnings, but it could still wreak havoc with other operators. Could fees soon become more interesting to miners?
Out of curiosity, what if the average fee increased? Four cents for a fast, worldwide transaction seems quite cheap after all! What if miners, for the most part, determined fees based on their physical world costs e. How many transactions currently pay a minimum 10c 26, satoshis per transaction or kilobyte for example? An average of KB per block is paying at least 10c per transaction or kilobyte.
How about 20c 52, satoshis per transaction or kilobyte? An average of KB per block is paying at least 20c per transaction or kilobyte. We could go on.. These are arbitrary numbers. These are ignored in the above figures. Out of curiosity, which miners are already dropping low-fee transactions? How about we first take a look at average weekly block size, by miners?
Let us again filter out some low-fee transactions and chart the average weekly block size. This query will be a little more difficult.
We will first create a temporary view for our transactions, joining the 'tx' and 'block' tables. We will now filter out transactions that do not include a minimum fee per kilobyte 10, satoshis per 1, bytes.
There seems to be a difference with Bitfury between those two charts. Let us count up all low-fee transactions there are not many over a week period and and see who is mining them. Blockbin was built with exploration and curiosity in mind. Originally developed to satisfy a private curiosity with Bitcoin trends, Blockbin is now encouraging others to play with this wonderful experiment known as Bitcoin.
Blocks are full, right? Apologies for any inconvenience. We hope to welcome you back in future with a possible relaunch. So, are blocks full? They are, however, very busy.
