Weekly news :
Ethereum and Bitcoin are preparing for some major upgrades :
The two main crypto-currencies on the market have approved (by recording a sufficient number of block agreeing on the fork) an update that will enhance the scripting capabilities of their network.
Bitcoin's Taproot :
It has been proposed in January 2018 to make Bitcoin transactions more efficients, privates, and scalables by implementing smart contracts. This upgrade is expected to make smart contracts cheaper and smaller regarding the space they take on the blockchain by using Schnorr signature.
Ethereum's London Fork :
This modificiation will change the ETH blockchain's transaction fee model :
-The network will now set a base fee for each block rather than bidding on gas prices.
The ultimate goal of the London's Hard Fork is to reduce the "Ethereum Difficulty Bomb Delay", which is the fact that mining ETH becomes exponentially more difficult over time, and will eventually lead to a mining duration that will discourage every users/miners.
To reduce it, this next upgrade will implement a base fee that depends on the current level of network congestion, and burn a certain amount. It will also dynamically increase or reduce the block sizes.
Both those upgrades are highly controversive in the crypto-ecosystem because they cut miners revenue but are also expected to solve many problems seen recently (high transaction fee, long duration transaction due to network congestion, and so on ...)
