Has the two generals problem been solved?
The (Almost) Solution It is impossible for both the armies to coordinate a time with 100% certainty. Most solutions to this problem simply accept the uncertainty of the communication channel and try to mitigate it. However, there is an almost-perfect solution which uses the absence of messengers to deliver a message.
What is the problem that Satoshi Nakamoto solved?
Nakamoto was not the first to hit on the concept of cryptocurrency but was the one to solve a fundamental problem that prevented its adoption: Unlike paper currency, cryptocurrency could be duplicated. This was known as "double-spending," and Nakamoto solved it by creating the blockchain system of verification.
Is the Byzantine Generals Problem solvable?
It is shown that, using only oral messages, this problem is solvable if and only if more than two-thirds of the generals are loyal; so a single traitor can confound two loyal generals. With unforgeable written messages, the problem is solvable for any number of generals and possible traitors.
Why is it called the Byzantine Generals Problem?
The term takes its name from an allegory, the "Byzantine generals problem", developed to describe a situation in which, in order to avoid catastrophic failure of the system, the system's actors must agree on a concerted strategy, but some of these actors are unreliable.
What do you understand by two general problems in blockchain?

How do you solve two general problems?
The story of the Two Generals' Problem General B is in the valley to the east. The only way you can defeat the enemy is if your soldiers and General B's soldiers make a coordinated attack from opposite sides of the valley.
How did crypto solve Byzantine Generals Problem?
Satoshi devised a means to use cryptographic security and public-key encryption to answer the Byzantine general problem in a digital electronic network. To prevent data tampering, cryptographic security uses hashing, a process of encoding. The identity of a network user is verified via public key encryption.
What problems can blockchain solve?
