TOPISTO

What is a TOPISTO ?

This is generative art. Each TOPISTO represents a block of the Bitcoin blockchain and is automatically generated by an algorithm. It use the Bitcoin Blockchain as a source of random for drawing pictures. To secure the transactions, each block have a hash, a cryptographic key that seals the block and will never change. Nobody can predict the hash of the next block of the blockchain. So nobody can know what the next picture will look like.

Each picture have 3 parts. The top strip represents the hash of the block. It contains information like the height or the name the block. The middle strip is the drawing. Method, colors, thickness ... Everything depends on the transaction within the block. The bottom strip represents the revert hash of the previous block. So, like in the blockchain, each TOPISTO is chained to the previous one.

Get your own TOPISTO !

Some blocks are special blocks. The first block in History is at height 0, it is called the GENESIS block. So special blocks have a name. Block at height 42, is "THE_ANSWER", because 42 is the answer to everything ! Each 210000 blocks, the reward is divide by 2, so those are HALVING blocks. The fisrt real BTC transaction was to buy 2 pizzas, this transaction is in the block 57035 which is named PIZZA block. The COVID19 pandemic kill some friend, so there is a RIP_STEEVE block.

Just like me, you will be able to name a block and put it in History as an NFT. This is not yet implemented, but it will be on this page. Buying a TOPISTO is a way for you to help me

R. Topisto is a Twitter Bot

I also create a bot (@r_topisto) that tweet the LAST TOPISTO almost every hour. It is doing that since march 2017. Sometimes lucky people mined block without any tranaction in it. They only get the reward without waiting transactions to put in the block. You can follow those events via my main twitter, @topisto_42
