MicroBitcoin

Initially original MicroBitcoin network has been launched 11 July 2018 as an hard fork of Bitcoin network.

Main focus was on ASIC[1] resistance and faster block time to be more suitable for micro-payments. To

make interaction with currency units easier decimal poin was shi!ed by 4 places making 1 BTC equal to

10,000 MBC.

First MicroBitcoin block was mined at 11 July 2018 causing hardfork by replacing default sha256d hash

function with NIST SHA-3 candidate Groestl[2] algo which didn't had ASIC implementation at the time and

because of that was considered ASIC resistant. Time proven that this assumption was wrong a!er Baikal

released[3] BK-G28 featuring Groestl support on 26 October 2018. Since this time BK-G28 miners had been

main source of hash power on MicroBitcoin network fundamentally corrupting decentralization. A!er

extensive research we stopped on Rainforest[4] PoW algo by Bill Schneider. On 6 March 2019 MicroBitcoin

network hardforked to Rainforest and on 7 May 2019 to second version of Rainforest (also known as RFv2)

which fixed some flaws of original algo.

A!er a while it became clear that Rainforest v2 algorithm is way to slow during PoW validation phase and in

combination with more than 200 GB of blockchain size make it very hard to sync/keep full node of

MicroBitcoin essentially undermining decentralization. This situation became the main reason behind

launch of new network
